The flosser shelf. Seven records judged on the documents they publish: the pressure range no maker prints on the page that sells the machine, the acceptances that stand in the ADA's own directory and the ones that stand only in copy, and a warranty column that runs from three years to a lifetime that expires with a subscription. The hero frame is one of the bank's portraits; the photo bank holds no water flosser product photography and no bathroom-shelf frames, so the cards below run imageless, as every grooming Card here does.
Checked and updated October 2026
The short version: Waterpik's Aquarius WP-660, the countertop standard with the most complete published record on the shelf, wins at 87, with Philips' Sonicare Power Flosser 5000 at 82 and Waterpik's Cordless Advanced 2.0 at 80 behind it. The counts the whole table rests on: a pressure range with its unit printed on the US product page itself, 0 of 7. The same range printed anywhere in the maker's own published record, 2 of 7, both Waterpiks, one in a manual's specification table and one in the maker's British table. A warranty term standing in the maker's own record, 7 of 7, running from one year to three, with an eighteen-month term on the sent-home card. A tip or nozzle price printed on the maker's own store, 1 of 7. An acceptance standing in the ADA's own directory as read, 2 of 7. The door prices run from $45 to $99.99. The Colgate Blast is sent home: its maker does not sell it in this country.
First, the decision
The default buy: Waterpik Aquarius WP-660, 87. The complete page, the seven tips, the three-year term and the directory standing, bought knowing its famous pressure range lives in its manual.
The footnoted-claims case: Philips Sonicare Power Flosser 5000 HX3811/20, 82. Ten intensities, the big tank and claim footnotes that name their own study basis, over a record that prints no pressure figure in any unit.
The travel case: Waterpik Cordless Advanced 2.0 WP-582, 80. The fullest cordless spec table here and four weeks a charge, on a page that prints two different charge times.
The printed-warranty case: quip Rechargeable Cordless Water Flosser, 74. The warranty written out entire on the page and the shelf's lowest door, against almost no numbers at all.
The full-page case: Oclean W10, 71. Every headline number on one page that prices itself, with the pressure figure absent and the tip record offshore.
The battery case: BURST Water Flosser, 66. Eighty days a charge, on a product page that prints almost none of its own numbers.
Sent home: Colgate Blast Portable Water Flosser. A real record standing on the wrong continent. The full case is at the foot of the cards.
This shelf, in three findings
The pressure range is the category's missing column, and settings counts are printed in its place
Count the makers who print the one number this category can be compared on, the pressure range in pounds per square inch, on the US product page that sells the machine. None of seven. Widen the count to the maker's whole published record and it reaches two, both from one house. Waterpik prints the Aquarius range, 10 to 100 PSI, in the model's own manual, in its specification table, a document a buyer opens after the purchase or never; the letters PSI do not appear on the Aquarius product page itself. The same house prints the Cordless Advanced range, 45 to 75 PSI, in the specification table on its own British site; its US page prints settings, flow and pulses and no range. Philips, whose toothbrush pages on Card No. 125 printed a movement figure, prints no pressure figure in any unit for the Power Flosser 5000: no PSI, no pulses a minute, no flow rate, only two modes and ten intensities it calls pressure settings without printing a pressure. quip prints none, BURST prints none, Oclean's US page prints none, and the Colgate record prints none where it stands. In the missing column's place the shelf prints settings counts, and a settings count is not a pressure. Ten at Waterpik span the manual's 10 to 100; ten intensities at Philips span a range the maker declines to state; three modes at BURST span another. The counts look comparable and are not, which is the same shape Card No. 126 found among the steamer wattages and Card No. 124 among the trimmer motors: the loudest number in the category is the one that cannot be checked against anything.
The directory, not the badge: two of seven stand where the ADA keeps its own list
Every acceptance on this page was graded in the ADA's own Seal directory, read product by product on October 23, 2026, never from a maker's badge, the method Card No. 125 set for the toothbrushes. Two records stand there. The Waterpik countertop family stands under the directory's own entry for the Waterpik Countertop Family Water Flosser, and the Aquarius was named in the acceptance when the Seal was first granted in this category, the first powered interdental product to earn it. The Philips Sonicare Power Flosser stands under a directory entry of that name. The Cordless Advanced carries its acceptance printed by its maker on the model's own page, image and all; the directory pages this desk read name the countertop family, the whitening flosser and the Sonic-Fusion hybrid, so the cordless claim is graded as the maker's claim, printed as such on its card. The quip flosser does not stand, and the cleanest evidence is the house's own: quip's published list of its Seal products names its electric toothbrush, its refillable floss string and its toothpaste, and the flosser is not on it, whatever the roundups say. BURST, Oclean and Colgate print no claim, and none was found. The ADA's own consumer page carries the necessary fairness, and this page repeats it: a missing Seal is not a failed test, because a maker has to apply. What is graded here is narrower and harder: whether a claim a buyer meets also stands in the body's own list. On this shelf, twice yes, once on a maker's word, four times not claimed at all.
The tip is the running cost, and one maker of seven prints what it costs
A water flosser is a machine that eats tips, and the shelf's documents treat that cost the way Card No. 126's shelf treated its steam times: mostly by not printing it. One maker of seven prints a tip price on its own store. Waterpik sells the Precision tip, the everyday JT-100E, at $14.99 for two on waterpik.com, with the interval printed on the same page, replace every six months, and its instructions for use print the per-tip table entire: the Orthodontic, Pik Pocket and Plaque Seeker tips at three months, the Precision and Tongue Cleaner at six. Philips prints its interval, replace the nozzle every six months, in its own instruction pages, and lists three nozzle types in two-packs whose prices would not render on the maker's pages as read. quip prints the cadence, fresh floss tips every three months on its refill plan, and not the plan's price on the product page. BURST sells its tips in two-packs and on subscription, prints neither a price nor an interval on its product page as read, and then does the shelf's most interesting thing with the gap: its published terms give the device one year of warranty, or a limited lifetime warranty for exactly as long as a tip subscription runs, so the tip programme is not an accessory to the warranty, it is the warranty. The warranty column itself runs one year to three, and the three belongs to the winner. A buyer pricing these machines on door prices alone is pricing the first year of a relationship whose terms, intervals and tip bills are all printed somewhere on this page, because the desks that published them put them in four different documents.
How the scores work
Each card is scored out of 100 on five rows. Specification & claim honesty (30) grades whether the published record matches the name on the box and the claim in the copy: whether a pressure range stands printed by the maker and on which document, whether a maker's page agrees with itself where it prints the same fact twice, whether an acceptance printed in copy also stands in the ADA's own directory, and whether a tank is printed as a volume or only as the seconds it lasts. Pressure & session record (20) grades the session as published: the range where one stands, the settings counted against it, the pulses and flow where printed, the tank and the session counted against it, and the cord or battery behind it. Fit & format (20) grades the format as printed against the job: countertop against handheld, the tips and nozzles counted and itemised as printed, and the box as the maker lists it. Value (15) grades the checked door price against the printed record, with the running cost of tips counted where a maker prints one. Longevity & service (15) grades the maker's printed warranty term and the tip programme behind it, a term printed on the model's own documents counted above one that lives only in a house's policy copy. Scores grade documents, not cleaning. Cleaning performance is graded nowhere on this page: this desk flossed nothing, and that discipline is printed again in the honesty section below.
The shelf, scored
Waterpik Aquarius WP-660
The winner is a product page that behaves like a specification sheet, the only one on this shelf that does. Waterpik's own page for the WP-660 prints the session entire: ten pressure settings, a PRECISIONPULSE action at 1,400 pulses a minute, a flow rate of 13 ounces a minute, a reservoir of 22 ounces (651 millilitres) counted by its maker as more than ninety seconds of flossing time, a one-minute timer with a thirty-second pacer, an LED pressure display, an on and off switch on the handle, and a swivel handle the copy says rotates 360 degrees. The box is itemised on the page as seven tips: four Precision tips with an Orthodontic tip, a Plaque Seeker tip and a Pik Pocket tip, one of the only two full tip counts on the shelf. The warranty stands on the page, a three-year limited warranty, thirty-six months, the longest term printed by any maker here. Its acceptance stands where this page requires acceptance to stand: the ADA's own directory carries the Waterpik Countertop Family Water Flosser, and the Aquarius was named in the acceptance when the Seal was first granted in this category, the first powered interdental product to hold it. Two deductions stand beside the win, both printed. The pressure range the whole internet quotes for this machine, 10 to 100 PSI, does not appear on its US product page at all; it stands in the model's own manual, in the specification table, and a buyer who wants the category's one comparable number has to open the manual to find it. And the house prints its tip interval two ways: the page's own FAQ says replace tips every three to six months, while its instructions for use print the per-tip table, the Precision tip at six months and the three specialty tips at three, and the Precision tip's own store page prices the pair at $14.99 with the six-month interval printed on it, the shelf's only tip price standing on a maker's own store. The format's terms are printed too: corded, a 52-inch cord, and 120-volt North American current only, on the page in plain type. It wins as the record a buyer can check most completely before he pays, manual opening included.

Philips Sonicare Power Flosser 5000 HX3811/20
The best-mannered claims on the shelf, attached to its emptiest pressure column. Philips' own page for the Power Flosser 5000 prints what it prints cleanly: two modes, Clean and Deep Clean, across ten intensities the maker calls pressure settings, without printing a pressure; a reservoir of 550 millilitres, the shelf's largest tank, in a corded countertop body on a magnetic dock with an automatic shut-off when the unit lifts from it; and a two-year warranty printed on the page. Its claim discipline is the category's best and this card credits it in full. The page's headline claims carry their basis in the maker's own disclaimers: the seven-times and 180% figures footnoted to a two-week study, the Quad Stream nozzle on setting eight, moderate-to-severe gingivitis patients, against manual brushing and string floss; and the house's own category copy names the basis of its area claim entire, an in-vitro study against the Waterpik 660 with its Classic Jet nozzle at setting eight, the competitor and the setting printed where a buyer can find them. Card No. 125 graded this house's footnotes highly and does again. The nozzle system is printed as a system: three types, the F1 Standard, the F2 Comfort and the F3 Quad Stream, sold in two-packs, with the replacement interval, six months, standing in the maker's own instruction pages. The acceptance stands: the ADA's own directory carries the Philips Sonicare Power Flosser under that name. What the record never prints, anywhere this desk could read, is a pressure: no PSI, no pulses a minute, no flow rate, on a machine whose entire marketing case is a comparison of cleaning force. The deduction is the shape of the one on Card No. 125's Oral-B row: the maker's page asks to be believed on the number it declines to publish. The card also carries no pill, because the price would not render from the maker's own pages as read, and this desk does not point a buy button at a listing it could not verify on the maker's shelf.
No pill: the price would not render from the maker's own US or Canadian pages as read. US retail readings for the 5000 stand at $99.96 (Walmart's listing); the card ships without a buy button rather than point at a door this desk could not verify on the maker's own shelf.

Waterpik Cordless Advanced 2.0 WP-582
The fullest cordless record on the shelf opens Waterpik's own specification table for the WP-582: three pressure settings, 1,250 pulses a minute, a flow rate of 10 ounces a minute, a reservoir of 7 ounces (207 millilitres) counted at forty-five seconds, four tips itemised as two Precision tips with an Orthodontic and a Plaque Seeker, up to four weeks of use a charge from its lithium-ion cell, a magnetic USB charging cable, global voltage, and a two-year limited warranty, twenty-four months, printed in the table itself. The page's honesty about the box is the shelf's best small print: the wall adapter is not included, printed as a fact rather than discovered as one, and the tip interval stands in the page's own FAQ, replace tips every three to six months. Two deductions hold it at 80. The first is a disagreement inside one page: the features list advertises a four-hour rapid magnetic charging system while the same page's own FAQ instructs the buyer to charge the unit for about eight hours. The four-hour figure is the previous model's headline, carried into this page's copy; a buyer cannot obey both numbers, and this page grades the maker for printing them. The second is the range. The US page prints no PSI; the range for the line, 45 to 75 PSI, stands in the specification table on the maker's own British site, the same manual-class exile as the winner's, one border further away. Its acceptance is printed by the maker on the page, seal image and all, and is graded here as the maker's claim: the ADA directory pages this desk read name Waterpik's countertop family, whitening flosser and Sonic-Fusion hybrid, and Waterpik's own acceptance article footnotes that the Seal applies to most models. Bought at the same $99.99 as its countertop brother, it is the cordless record to beat, contradictions printed.

quip Rechargeable Cordless Water Flosser
The best small print on the shelf and the emptiest number column on it, on one page. quip's own page for its rechargeable cordless flosser prints its warranty entire, the only house here that does: one year from purchase against defects in materials and workmanship, with the exclusions named, wear and tear, misuse, dropped water damage and lost items, and the remedy stated, replace the device or refund the price. Its thirty-day returns stand beside it. Its battery claim carries its condition in the same breath, up to eight weeks used daily, on its gentle mode, and its plaque claim wears its asterisk where a buyer can see it. The tip record is a plan: one magnetic floss tip with a 360-degree range of motion, and fresh tips every three months under the house's refill plan, whose cadence is printed on the page and whose price is not. Then the column runs out. Two pressure modes are named, gentle and deep clean, with on-demand and continuous flow; no PSI, no pulses, no flow rate. The reservoir is quantified only in time, sixty seconds of flossing per fill on gentle, no millilitres anywhere on the page, so the tank cannot be compared with the 7 ounces and 200 millilitres printed by its neighbours. And the flosser does not carry the house's acceptance: quip's own published list of its Seal products names its electric toothbrush, its refillable floss string and its toothpaste, and this device is not on it, a fact graded from the house's own page, not from the roundups that claim otherwise. The price is the shelf's lowest door, $45 against a struck $75 list for the metal model, and the value row credits it. A buyer who reads documents before prices will find this page the most honest and the least checkable of the six, both at once.

Oclean W10
A US page that prints nearly everything except the one number the category runs on. Oclean's own page for the W10 lists five flossing modes, named in the maker's own launch material as Intensive, Standard, Gentle, Pulsating and On-demand; a motor figure of 1,400 pulses a minute, matching the winner's; a detachable 200-millilitre tank; a fifty-second quad-pacer in the copy and up to thirty days of battery a charge; an IPX7 body; a thirty-day money-back guarantee; and a two-year warranty, printed on the page. It prices itself, $89.99 against a struck-through $109.99 list, one of only two houses here whose own page carries both the numbers and the price. The deductions are absences, and they are graded as absences. No pressure figure stands on the US page in any unit; the 30 to 100 PSI range attached to this model stands in retail specification tables, which is retail copy, and is graded as such. The box count disagrees across the house's own border: the maker's US page prints two high-performance nozzles in the box, while US retail listings for the same model describe four attachments; the maker's number governs on this card and the disagreement is printed here rather than resolved quietly. The tip record stops at the water's edge: no replacement interval and no nozzle price stand on the US page, and the maker's own launch material prices the nozzle two-pack at an Australian RRP of AUD 29.95, a figure a US buyer cannot pay against. No acceptance claim is printed and none was found in the ADA's directory as read. It is a fuller page than the two cards above it and a thinner record than either, because the numbers it prints are the ones that cannot be checked against a rival's.

BURST Water Flosser
The last card is where the documentation discipline of this run meets a house that keeps its numbers anywhere but on its own product page. BURST's own page for its water flosser, read entire, prints the price, three colours, a 360-degree rotating tip, three tip types described in its copy, the everyday Classic, the silicone Perio and the bristled Ortho, a travel bag in the box and use in the shower. It prints no tank size, no battery figure, no mode count and no warranty term. The numbers exist, in the house's marketplace listings and support copy: three modes named Standard, Turbo and Pulse, a 110-millilitre tank, an eighty-day battery, the shelf's longest, and one Classic tip in the box with the Perio and Ortho sold separately. They are graded here as the house's listings, one document class below a product page, and the gap between what this house knows and what its own shelf says is the card's central finding. The warranty, in the house's published terms, is one year on the device, or a limited lifetime warranty for exactly as long as a replacement-tip subscription runs: a lifetime measured in subscription months, graded as printed, neither as a year nor as forever. The pressure figure attached to this machine in review copy, upwards of sixty PSI, is not the house's print; BURST prints no PSI anywhere this desk could read, and prints no acceptance claim, and none was found in the ADA's directory. Replacement tips are sold in two-packs and on subscription, with neither a price nor an interval standing on the product page as read. None of this makes the machine bad; this page does not grade machines. It makes the record the thinnest of the six seated, on a shelf where the record is the product being bought blind.

Sent home: Colgate Blast Portable Water Flosser
No pill on a sent-home card: the record stands on the maker's Singapore and Malaysia pages, and no US first-party door with a US price stood open at the check.
The Blast is sent home on geography, and its record is printed whole so the ruling can be judged. On Colgate's own Singapore and Malaysia pages the device stands as a real product: three pressure modes named Gentle, Regular and Pulse, up to sixty seconds of water capacity from its reservoir, a rechargeable battery lasting more than three weeks on the gentle mode with the condition asterisked on the page itself, nozzles that retract and store inside the body, and an eighteen-month warranty printed on the Malaysian page, a longer term than two of the cards seated above it carry. The manners are not the problem. The problem is the map. Colgate's own US site does not list the device at all; the record prints no pressure range and no tank volume in millilitres, no ADA standing and no US price from its maker, and a United States buyer meets the machine only as a marketplace import wearing a third party's listing, at a price the maker never printed. Card No. 125 sent the hum brush home when its maker's own shop sold the name in this country only as a kids' manual brush; this name's maker does not sell the device in this country at all. A Card that grades the record a buyer can check and pay against cannot seat a record that stands on another continent, so the Blast is sent home with its foreign record attached and labelled, to be reseated the day Colgate prints a US page for it.

Which one to buy
Buy the Aquarius (87) if the record is the purchase. Ten settings you can map to a printed range in its manual, seven tips itemised, the longest warranty on the shelf, tips priced on the same store that sells the machine, and an acceptance that stands in the body's own directory. The two deductions are on its card; neither is hidden.
Buy the Power Flosser 5000 (82) if you want the claims with their homework attached. Philips prints the basis of its comparisons where you can read them, seats its acceptance in the directory, and runs the biggest tank here. You are buying ten intensities whose pressure the maker will not state, and you will pay a retail price this desk could not verify on the maker's own shelf.
Buy the Cordless Advanced 2.0 (80) if the bathroom has no counter to give. The fullest cordless table here, four weeks a charge and the adapter's absence printed before checkout. Charge it for the eight hours its FAQ says, not the four its features promise.
Buy the quip (74) if you read warranties and hate clutter. The warranty is written out entire, the returns are printed, the battery claim carries its condition, and the door is the shelf's lowest. You give up every comparable number: no pressure, no pulses, no millilitres, and no directory standing for the device.
Buy the W10 (71) if the page itself is the evidence you want. Modes, pulses, tank, battery, money-back and warranty on one US page that prices itself. Its pressure figure lives in retail tables and its tip prices in another hemisphere's launch release.
Buy the BURST (66) if eighty days between charges is the whole argument. The battery is real in the house's own copy. Everything else about the machine lives in that copy too, because the product page that sells it prints almost nothing, and its lifetime warranty lasts exactly as long as you keep paying for tips.
Buy none of them off a settings count. A setting is a position on one house's dial. Two of these makers print the range those positions span, both in documents other than the page selling the machine; the rest print positions and call the column pressure. Read the range column in the table above before the door prices, and let the directory, not the badge on the box, tell you which acceptances stand.
How we tested (and what we rested)
This desk flossed nothing, and the page says so wherever a score could be mistaken for a use claim. Every record was graded from published documents read on October 23, 2026: the maker's own product page or shop where it could be read, the maker's own manual, specification table and instruction pages where the page ran thin, the maker's own warranty text where a term lived there, the ADA's own Seal directory for every acceptance graded, and the merchant shelf for the doors. Claims about plaque, gingivitis and multiples of string floss were graded as claims, in the makers' words, with the basis printed where the maker prints one. Rested, with the reasons printed: the Waterpik countertop line beyond the Aquarius, rested for its fullest record, and the cordless line beyond the Advanced 2.0, rested for the same reason; the Waterpik Sonic-Fusion, a toothbrush with a flosser in the handle, rested as a hybrid on Card No. 125 and rested here on the same ground, though the directory seats it in this category; the Philips Cordless Power Flosser 3000, rested because the maker's own US page marks the model discontinued, its record divided against itself besides, fourteen days of battery in its specification sheet against up to forty days in the house's current cordless copy; the Philips Power Flosser 7000 system, a bundle built around a toothbrush, rested for the 5000; and the marketplace-first labels whose announcements this desk read, including the maker's June 2026 announcement of an ADA acceptance for its flossers, rested entire, because this Card grades first-party product records and theirs stand on listings. The Colgate Blast was graded in full from the pages where its maker does sell it, and sent home rather than rested, so its record stands in the open.
The honesty paragraph: Young Cotton has no laboratory, no test bathroom and no dental credentials, and nothing in this ranking rests on a use claim: no flosser here was filled, charged, run against a gumline or timed, by us or by anyone whose results we repeat. Efficacy is graded nowhere. The plaque percentages, gingivitis claims and string-floss multiples in these documents appear on this page only as claims, with the study basis printed where the maker prints one, the way Card No. 125 handled the brush claims and Card No. 122 the rinse claims. Every acceptance was read in the ADA's own directory on October 23, 2026, product by product; where the directory's own search page would not render its text, standings were read from the directory's own product pages, and the maker's claim is labelled the maker's claim wherever the two diverge. Where a maker's own US page would not render a price, the card says so and carries no pill. Where a record stands at retail or in a foreign storefront of the same maker, the card grades it as that copy and prints the geography. If a maker prints the missing pressure figure on its US page, prices its tips on its own store, or lists the sent-home device in this country, write to the desk and the card will be rechecked against the new document.
The directory method here is Card No. 125's, set among the electric toothbrushes, where the same directory seated four brushes and no Sonicare. The missing output column is Card No. 126's shape exactly, among the garment steamers, where two makers of eight printed the number the category runs on. The motor-figure lesson is Card No. 124's, among the nose hair trimmers, where one house printed two speeds for one retired model. And the name-over-several-records lesson is Card No. 122's, among the mouthwashes, where one name covered three different panels.
Questions, answered plainly
Why does the Waterpik Aquarius win a water flosser ranking?
Because this page grades documents, and the Aquarius page is the most complete record on the shelf. Waterpik's own product page prints the session entire: ten pressure settings, 1,400 pulses a minute, a flow rate of 13 ounces a minute, a reservoir of 22 ounces counted as more than ninety seconds, a one-minute timer with a thirty-second pacer, seven tips itemised by name, and a three-year limited warranty, the longest term printed here. Its acceptance stands where this page requires acceptance to stand, in the ADA's own directory, under the Countertop Family entry, with the Aquarius named in the acceptance from the first. The deductions stand on the card beside the win. The pressure range the whole internet quotes for this machine, 10 to 100 PSI, does not appear on its US product page at all; it stands in the model's own manual, in the specification table. And the house prints its tip interval two ways, three to six months in the page's own FAQ against a per-tip table in its instructions that runs the everyday tip to six months and the three specialty tips to three. It wins as the record a buyer can check most completely before he pays, with its two untidinesses printed where they belong.
Which of these flossers print a pressure range, and why does the unit matter?
None of the seven print one on the US product page itself, and two of the seven print one anywhere in the maker's own published record. Both are Waterpiks. The Aquarius range, 10 to 100 PSI, stands in the model's own manual, in its specification table. The Cordless Advanced range, 45 to 75 PSI, stands in the specification table on the maker's own UK site. Philips prints no pressure figure in any unit for the Power Flosser 5000, no PSI, no pulses, no flow; quip, BURST and Oclean print none on their US pages, and the Colgate record prints none on the pages where it stands. The unit matters because PSI is the only pressure column two makers can be compared on. A settings count cannot do the work: a setting is a position on one house's dial, not a pressure. Ten settings at Waterpik span the manual's 10 to 100; Philips' ten intensities span a range the maker declines to print; BURST's three modes span another. A buyer comparing settings counts is comparing the wrong column, the same wrong column Card No. 126 found among the steamer wattages and Card No. 124 among the trimmer motors.
Which of these actually stand in the ADA's own directory?
Two of the seven, as this desk read the directory on October 23, 2026, product by product, the way Card No. 125 read it for the toothbrushes. The Waterpik countertop family stands, under the directory's own entry for the Waterpik Countertop Family Water Flosser, and the Aquarius was named in the acceptance when the Seal was first granted in this category. The Philips Sonicare Power Flosser stands, under its own directory entry of that name. The Cordless Advanced's acceptance is printed by its maker on the model's own page; the directory pages this desk read name the countertop family, the whitening flosser and the Sonic-Fusion hybrid, and the card grades the cordless claim as the maker's claim. The quip flosser does not stand: quip's own published list of its Seal products names its electric toothbrush, its refillable floss string and its toothpaste, and the flosser is not on it. BURST, Oclean and Colgate print no acceptance claim, and none was found in the directory as read. A missing Seal is not a failed test, and the ADA says so itself: a maker has to apply. What a buyer can hold is the difference between a claim that stands in the directory and a claim that stands only in copy, and on this shelf that difference is printed on every card.
Countertop or cordless: what do the printed records say the two formats are for?
The documents draw the line at the tank, and the tank draws it at the session. The countertop records carry 22 ounces and 550 millilitres and print sessions counted past a minute and a half, or, in the Philips case, a tank its maker says holds more than one session; they are machines that live at a wall, the Aquarius by a cord its maker limits to North American current, printed on its page. The cordless records carry 45 to 60 seconds a fill, 7 ounces at the largest, and pay for the format in a second currency, the weeks between charges: four weeks at Waterpik, up to eight at quip on its gentle mode, eighty days claimed by BURST, thirty printed by Oclean. The refill is the cordless tax and every maker here prints it, in seconds. What no document on this shelf prints is a cordless machine that finishes a long session without a refill or a countertop machine that works in the shower, and a buyer whose bathroom has no free outlet who bought the Aquarius has misread the power column, which is printed on its card.
Why was the Colgate Blast sent home?
Because this Card grades the record a United States buyer can check and pay against, and the Blast has no standing record in that country. Colgate's own US site does not list the device. The record stands on the maker's Singapore and Malaysia pages: three pressure modes named Gentle, Regular and Pulse, up to sixty seconds of water capacity, a rechargeable battery lasting more than three weeks on the gentle mode, an eighteen-month warranty printed on the Malaysian page, and nozzles that retract into the body. It is not a disgraceful record; parts of it, the asterisk on the battery claim and the printed warranty term, are better mannered than records seated above it. But it prints no pressure range, no tank volume in millilitres, no ADA standing and no US price from its maker, and a US buyer meets the machine only as a marketplace import wearing someone else's listing. Card No. 125 sent the hum brush home when its maker's own shop sold the name only as a kids' manual brush; this name's maker does not sell the device in this country at all, so the card is sent home with its foreign record attached and labelled.
Did you floss with any of these?
No. Nothing on this page was filled, charged, run against a gumline or timed against a clock, and no score rests on a use claim. Every number grades published documents: the maker's own product page or shop where it could be read, the maker's own manual or specification table where the page ran thin, the maker's own warranty and instruction pages where a term or an interval lived there, the ADA's own Seal directory for every acceptance graded, and the merchant shelf, all read on October 23, 2026. Cleaning performance is graded nowhere on this page: plaque percentages, gingivitis claims and multiples of string floss appear only as claims inside the documents graded, with the basis printed where the maker prints one. Where a claim exists only in retail or review copy, the card grades it as that copy, and says so.
