Philips Sonicare Countertop Power Flosser 3000 (HX3711/20)
A corded countertop flosser with a 550 ml tank, ten pressure settings and an X-shaped Quad Stream nozzle, sold on usa.philips.com as the HX3711/20
Scored on the published rubric, from documentation, pricing and verified user reports.
Best for: Buyers who want the biggest documented tank in this price band and the cheapest replacement nozzles, and who do not need the orthodontic or implant tips that Waterpik sells for its own flossers.
Verdict
The Sonicare Countertop Power Flosser 3000 is the cheapest countertop water flosser from a major brand we have graded, and it leads on exactly one number: the tank. Philips lists 550 ml, described as sufficient for a 90-plus second clean, against 651 ml on Waterpik's Aquarius and 473 ml on the Sonic-Fusion 2.0. It costs $89.96 on usa.philips.com and takes ten pressure settings across two modes, Clean and Deep Clean, with a pacer that pauses every 30 seconds. This is a documentation review built from the Philips product page, the product specification data Philips publishes for the HX3711/20 and the ADA's own interdental cleaning guidance; we did not operate the unit. Three things hold the grade down, and all three are about missing documentation rather than missing hardware. Philips publishes no PSI range, no flow rate, no pulses-per-minute figure, no dimensions and no weight for this model in its own specification data, which makes it hard to compare against a Waterpik on anything but tank size. The warranty is 24 months, against 36 on two Waterpik countertop units. And the nozzle range is three, F1, F2 and F3, with no orthodontic or implant-specific tip.

Where it is strong
- 550 ml tank, the largest in millilitres at this price point, described by Philips as sufficient for a 90-plus second clean
- $89.96 on usa.philips.com, the lowest price of any countertop flosser from a major brand we have graded, checked October 30, 2026
- Ten pressure settings across two modes, matching Waterpik's countertop count rather than the three on cordless models
- Replacement nozzle packs at $14.96 for two tips, which is the cheapest documented consumable in this cluster
- Two nozzles in the box, one F1 Standard and one F3 Quad Stream, plus a multi-voltage power adapter
Where it falls short
- Philips publishes no PSI range, flow rate or pulses-per-minute figure for this model in its own specification data
- No dimensions and no weight in Philips' specification data, so counter fit cannot be checked before buying
- 24-month limited warranty, against 36 months on Waterpik's Aquarius and Sonic-Fusion 2.0
- Three nozzle types only, F1, F2 and F3, with no orthodontic or implant-specific tip in the range
- The ADA Seal is not mentioned anywhere on the Philips product page, and we could not open the ADA's own listing for this brand on October 30, 2026

What the Power Flosser 3000 actually is
The Sonicare Countertop Power Flosser 3000 is Philips' entry-level mains-powered water flosser for the US, sold as model HX3711/20 in white.
A base holds the 550 ml tank and the power adapter, a hose runs to a handle, and the handle takes one of three nozzles.
The design idea Philips sells is the nozzle rather than the pump. Quad Stream is a cross-shaped tip that splits the water into four wide streams, and Pulse Wave adds a rhythm meant to walk you from tooth to tooth.
It is also the cheap end of a three-model line. The Power Flosser 7000, model HX3911/30, was marked Discontinued on Philips' own site on October 30, 2026.
A Cordless Power Flosser 3000 sits alongside this one, with a 250 ml tank and three pressure settings.
This is a documentation review. Figures come from Philips' product page, the specification and disclaimer data Philips publishes for the HX3711/20, and the ADA's interdental cleaning guidance, all read October 30, 2026. We did not operate the unit.
Who the Power Flosser 3000 is best for
On the documentation, this suits a buyer who cares about tank size, price and consumable cost more than about specification depth.
- People who refill a small reservoir mid-session and want 550 ml instead
- First-time water flosser buyers who do not want to spend $100 to find out whether they will keep it up
- Households already inside the Sonicare ecosystem, where one brand covers the brush and the flosser
- Buyers watching running costs, given $14.96 for a two-nozzle pack
- Two-person households, since Philips sells the F1, F2 and F3 nozzles in two-tip packs
- Anyone who wants ten pressure steps rather than the three on most cordless units
- People with sensitive gums, who can start on the F2 Comfort nozzle and the lowest of ten settings
Who should skip it
Three groups should look at a Waterpik instead.
- Anyone with braces or implants, because the three-nozzle range has no tip specified for either case
- Anyone who buys on measured figures, since Philips publishes no pressure, flow or pulse rate for this model
- Anyone whose counter space is tight, because Philips publishes no dimensions for it
What is in the box, and what Philips does not print
Philips' own specification data lists the box contents precisely: one Countertop Power Flosser 3000, one F1 Standard nozzle, one F3 Quad Stream nozzle and one power adapter.
Two nozzles for $89.96 is modest against Waterpik's seven on the Aquarius, but both of the Philips nozzles are different designs rather than duplicates.
What is missing is measurement. We read Philips' published specification data for this model on October 30, 2026. It contains no PSI range, no flow rate, no pulses per minute, no dimensions, no weight and no noise figure.
There is a Voltage row, and its entire value is the phrase multi-voltage charger. There is no stated voltage range, which matters if you travel.
We are not saying Philips withholds these figures on purpose. We are saying they were not readable in the vendor's own product page or specification data on the day we checked, so no comparison table can carry them.
How the pricing is structured (as of October 2026)
Usa.philips.com listed the HX3711/20 at $89.96 on October 30, 2026, with availability marked InStock in the page's own product data.
The same page showed add-to-cart prices of $14.96 each for the F2 Comfort nozzle and the F3 Quad Stream nozzle, each pack holding two tips.
Philips' specification data says to replace nozzles every six months. Our arithmetic, not Philips': a single user on that schedule spends about $15 a year, and a two-person household about $30.
For comparison, the Waterpik Aquarius listed at $99.99 on waterpik.com on the same day with seven tips in the box, so the first-year cost of the two machines is close.
Philips also prices the brand's own replacement nozzles on the product page rather than sending you to a separate store, which makes the running cost easy to check before you buy.
Ease of use: what the 3.9 is built from
The ease score credits tank size, the pacer and the nozzle fitting.
A 550 ml tank described as sufficient for a 90-plus second clean means most users will not refill mid-session, which is the single most common complaint about small cordless flossers.
Philips' specification data lists a pacer that pauses every 30 seconds, a nozzle that easily clicks on and off, and a Whisper quiet design row.
The mode split is simple in a good way. Clean mode is a continuous flow for a 60-second pass; Deep Clean uses distinct pulses and is documented as a 90-second guided pass.
The deduction is for the unknowns. Without dimensions, weight or a stated voltage range, two ordinary pre-purchase questions, will it fit and can I travel with it, cannot be answered from the vendor's own data.
Features: what the 3.2 is built from
The feature set is competent and narrow. Ten pressure settings, two modes, two nozzle designs, a pacer and the Quad Stream head.
What the rest of this category offers and this model does not is a massage mode, a tip library and any published performance figure. Philips' own discontinued Power Flosser 7000 listed four flossing modes against this unit's two.
The nozzle restriction is explicit in Philips' data: fits only F1, F2 and F3 nozzles. Waterpik's countertop range includes a Plaque Seeker tip for implants, crowns and bridges and an Orthodontic tip for braces, neither of which has a Philips equivalent here.
Philips does mark a Great for implants and braces row Yes for this model, but that is a claim about the Quad Stream nozzle rather than a dedicated tip.
The score reflects a product that does one job at one quality level, with no published numbers to let you judge how well.
Value: what the 3.9 is built from
Value is the joint-strongest pillar, because the price and the consumable cost are both the lowest in this cluster.
$89.96 buys the biggest documented tank at this price, ten pressure settings and a cross-stream nozzle, from a brand with a large US service footprint.
$14.96 for two nozzles is cheaper per tip than any Waterpik tip pack we have priced, and nozzles are the only consumable on a corded flosser.
The score stops at 3.9 for two reasons. The warranty is 24 months where Waterpik's two countertop models document 36. And a buyer cannot price-compare performance, because there is no performance figure to compare.
For how we treat replacement-part intervals across grooming tools, see our note on how often to replace shaver heads and trimmer blades.
Support and warranty: what the 3.0 is built from
Support is the weakest pillar on this page, and the reason is the documentation rather than the service network.
Philips' specification data gives a 2-year limited warranty and nothing more: no exclusion list, no claims process, no returns window and no proof-of-purchase requirement in the data we could read.
By contrast, Waterpik publishes its full warranty text in the manual that ships with each flosser, including the exclusion of tips and batteries and a blunt statement that it does not guarantee parts availability.
The product page does link a support hub offering FAQs, user manuals and safety information, and Philips lists an accessory and spare-part route for the nozzles.
On the ADA Seal, we found no mention anywhere on the Philips product page on October 30, 2026.
The ADA's own listing for the brand's power flosser could not be opened that day, because the link redirected in a loop. We report that as unread, not as absent.
What owners report
Philips' product page showed an average of 4.0 out of 5 from 53 reviews on October 30, 2026, with 87 percent of reviewers saying they recommend the product.
Fifty-three reviews is a thin sample, and we weight it accordingly. For scale, Waterpik showed 2,905 reviews for the Aquarius WP-660 and 983 for the Sonic-Fusion 2.0 Professional on the same day.
Philips' own discontinued Power Flosser 7000 showed 4.7 from 106 reviews with 96 percent recommending, which is a better score on a sample that is also small.
We report the vendor's aggregates only. Philips states that its reviews are managed by Bazaarvoice under its authenticity policy, which we note but cannot independently verify.
What the health claims actually say
Philips makes three outcome claims for this model, and publishes a footnote for each. Reading the footnote is the whole exercise.
Up to 180 percent more effective than floss in improving gum health. The footnote: after two weeks, against string floss, with the Quad Stream nozzle.
Gently removes up to 99 percent of plaque up to 6 mm below the gumline. The footnote: in a lab study, with the Quad Stream nozzle, up to 6 mm periodontal pockets.
Removes up to 99.9 percent of plaque in treated areas. The footnote: in an in-vitro study, actual results may vary.
So one claim is clinical and short-term, and two are laboratory work rather than work in mouths. Philips also calls itself the dental professional recommended sonic toothbrush brand worldwide, which is a claim about brushes, not about this flosser.
The ADA's interdental cleaning page cites a 2019 Cochrane review that found the evidence for oral irrigators limited and inconsistent, graded low to very low certainty. Our note on what the ADA Seal and a pressure sensor tell you covers how to read these marks.
Alternatives
Choose the Waterpik Aquarius if you want published numbers. Waterpik lists 1,400 pulses per minute, a 13 oz per minute flow rate, seven tips, full dimensions and a 36-month warranty for $99.99.
Choose a Waterpik if braces or implants are the reason you are buying, because the Orthodontic and Plaque Seeker tips exist there and have no Philips equivalent in this range.
If brushing is the weaker half of your routine, spend the $89.96 there instead. The Oral-B iO Series 5 sits near this price with a pressure sensor, and the Oral-B iO Series 9 and Philips Sonicare 9900 Prestige lead our best electric toothbrushes guide.
To see those two brushes argued head to head, read our Oral-B iO Series 9 against the Philips Sonicare 9900 Prestige comparison.
Otherwise choose the Power Flosser 3000 if tank size, purchase price and cheap nozzles are what decide it for you.
Bottom line
The Philips Sonicare Countertop Power Flosser 3000 earns 3.5 overall on our rubric. It is the cheapest way into a countertop water flosser from a major brand, and the hardest to compare on paper.
What it wins on is concrete: $89.96, a 550 ml tank, ten pressure settings, two nozzle designs in the box and $14.96 two-packs after that.
What it loses on is also concrete. No pressure figure, no flow rate, no dimensions, no weight, a 24-month warranty, a three-nozzle range and no ADA Seal mention on the page.
Buy it if the tank and the price decide it. If you want numbers you can check against a rival, read our Waterpik Aquarius review instead. All figures were read on October 30, 2026 and will be rechecked.
Buy it if
- You refill too often on a small reservoir - 550 ml is Philips' own figure and the largest in this price band.
- You want the cheapest replacement tips - $14.96 for a two-pack is below any Waterpik tip pack we have priced.
- You want ten pressure settings under $90 - the countertop Waterpik Aquarius also lists ten, at $99.99.
- You already own a Sonicare brush - the nozzle range and spare parts stay inside one brand's supply chain.
Skip it if
- You want to compare pressure numbers - Philips publishes none for this model, so you are buying on claims rather than on figures.
- You wear braces or have implants - the F1, F2 and F3 range has no tip designed for either, while Waterpik lists both.
- You need to measure the counter first - Philips publishes no dimensions or weight for this model.
- You want the longest warranty - 24 months here against 36 on two Waterpik countertop units.
Frequently asked
How much does the Philips Sonicare Countertop Power Flosser 3000 cost?
Philips listed the HX3711/20 at $89.96 on usa.philips.com on October 30, 2026, with availability marked InStock in the page's own product data. The F2 Comfort and F3 Quad Stream replacement nozzle packs were listed at $14.96 each on the same page.
How big is the Power Flosser 3000 tank?
Philips lists 550 ml, described in its specification data as a 550 ml water tank sufficient for a 90-plus second clean. For comparison, Waterpik lists 651 ml on the Aquarius WP-660 and 473 ml on the Sonic-Fusion 2.0 Professional.
What pressure does the Philips Power Flosser 3000 deliver?
Philips does not say. We read the product page and the specification data Philips publishes for the HX3711/20 on October 30, 2026 and found ten pressure settings listed but no PSI range, no flow rate and no pulses-per-minute figure.
Does the Philips Power Flosser 3000 have the ADA Seal of Acceptance?
The Philips product page does not mention the ADA Seal anywhere, and the ADA's own product listing for the brand's power flosser could not be opened on October 30, 2026 because the link redirected in a loop. We cannot confirm it either way today.
What do the 180 percent and 99 percent claims mean?
Philips footnotes both. The 180 percent gum health claim applies after two weeks, against string floss, with the Quad Stream nozzle. The 99 percent plaque claim comes from a lab study using the Quad Stream nozzle in periodontal pockets up to 6 mm deep.
How often do the Philips nozzles need replacing?
Philips' specification data says to replace nozzles every six months for good hygiene, and that the unit fits only F1, F2 and F3 nozzles. At $14.96 for a two-pack, a single-user household spends about $15 a year by our arithmetic.
Is a water flosser a substitute for string floss?
No. The ADA's interdental cleaning page cites a 2019 Cochrane review that found evidence for oral irrigators limited and inconsistent, graded low to very low certainty, with most outcomes measured over one to three months. Ask your dentist what fits your mouth.
