Short answer
Wait on Waterpiks: on Nov 12, 2026 Keepa showed the Waterpik Aquarius WP-660 at the top of its range after a mid-October jump, and its lowest price of the past year came in Black Friday week 2025. The Waterpik ION was at its regular price. The Sonicare Power Flosser 3000 is already down. Final verdicts the week of Nov 20.
How we researched this
We did not use these flossers. Models come from our water flosser guide. How we judge a deal: we compare a listing with its own public Amazon price history, not with the struck-through “list” price. On November 12, 2026, at about 8:40–9:00 AM CT, we read the one-year and 90-day Keepa price-history charts for every pick below that has a locked ASIN (both the Amazon-sold line and the lowest “New” offer). camelcamelcamel, our usual second tracker, was still showing a Cloudflare challenge to our research machine on Nov 12, so we link it but did not read it. We describe where today’s price sits in each product’s own history and when the lower stretches happened. We do not print dollar figures: Amazon prices change hourly, so use the “check current price” buttons. Final deal verdicts land the week of Nov 20. Last updated November 12, 2026.

DudProof Pick
Waterpik ION Professional
A DudProof Pick is the product the evidence says is least likely to be a dud for most people. What our badges mean
These four come from our water flosser guide. Water flossers are a wait-for-it category this year. On Nov 12, 2026, Keepa showed the Waterpik Aquarius WP-660 at the top of its one-year range after a jump in mid-October, even though its lowest prices of the past year came in late November to early December 2025. The Waterpik ION was at its regular price with patchy availability. Only the Philips Sonicare Power Flosser 3000 was down, at its lowest level since last winter.
| Pick | Why testers like it | Price-history read (Nov 12) | Verdict | Link |
|---|---|---|---|---|
| Waterpik ION Professional | Wirecutter’s top pick; runs cordless once charged | Regular price; dips in Dec–Jan, mid-June to early July and mid-August to mid-September. Availability patchy since early November. Keepa B08V1LS3FZ · camelcamelcamel | Coming week of Nov 20 | Buy on Amazon |
| Waterpik Aquarius WP-660 | Wirecutter’s runner-up; just as effective, corded | Top of its one-year range after a mid-October jump. Lowest in late Nov–early Dec 2025 and late June. Keepa B00HFQQ0VU · camelcamelcamel | Coming week of Nov 20 | Buy on Amazon |
| Sonicare Power Flosser 3000 | Wirecutter’s cordless/travel pick | Down since about Oct 8 to its lowest level since winter; last year’s holiday price was lower. Keepa B0C8KHTD16 | Coming week of Nov 20 | Buy on Amazon |
| AquaSonic Precision | Wirecutter’s budget pick (Aug 2026) | No baseline: the AquaSonic listings we found are a different model (the Aqua Flosser), so our button opens a search | Coming week of Nov 20 | Find on Amazon |

The water flossers worth buying on sale
Waterpik ION Professional
Verdict coming the week of Nov 20. Pre-sale read (Nov 12): Keepa B08V1LS3FZ shows the ION at one regular price for most of the year, with lower stretches in December and January, mid-June to early July and mid-August to mid-September, plus a brief deeper dip in early May. From about Nov 3 the line turns patchy, which usually means the listing has been going in and out of stock. A real deal is a return to those lower stretches from Amazon or Waterpik; a third-party seller charging more during a stock gap is not a deal.
What a real deal looks like: a price at or near the low stretches in this item’s own Keepa/camelcamelcamel history, on the exact model below, sold by Amazon, the brand or an authorized seller. A “% off” badge measured against a list price nobody pays is not a deal.
Why it’s worth watching: Wirecutter’s testers unanimously chose it as the best countertop water flosser, and its rechargeable battery means it does not need an outlet by the sink.
Model check: Confirm “ION” in the title. Waterpik’s corded Aquarius looks similar on the counter but always needs a plug.
Full evidence: best water flosser.
Waterpik Aquarius WP-660
Verdict coming the week of Nov 20. Pre-sale read (Nov 12): Keepa B00HFQQ0VU shows the Aquarius jumping in mid-October to the top of its one-year range, where it sat on Nov 12. That matters because this is a classic set-up: its lowest prices of the past year came in late November to early December 2025 and in late June, and it was much lower in early October than it is now. If the Black Friday price only takes back the October jump, it is not a special deal.
What a real deal looks like: a price at or near the low stretches in this item’s own Keepa/camelcamelcamel history, on the exact model below, sold by Amazon, the brand or an authorized seller. A “% off” badge measured against a list price nobody pays is not a deal.
Why it’s worth watching: Just as effective as the ION in Wirecutter’s tests, with 10 pressure settings. It is bigger and stays plugged in. Waterpik sells replacement reservoirs for it.
Model check: Confirm “WP-660” or the same Aquarius in another color. Bundles with a second flosser or extra tips are only a deal if you need them.
Wirecutter’s runner-up in our guide.
Philips Sonicare Cordless Power Flosser 3000
Verdict coming the week of Nov 20. Pre-sale read (Nov 12): Keepa B0C8KHTD16 shows it at one higher price from late January to early October, then a step down around Oct 8 to the level it held last winter. On Nov 12 it was still there. Its lowest price of the past year came in November and December 2025, so Black Friday could go a little lower.
What a real deal looks like: a price at or near the low stretches in this item’s own Keepa/camelcamelcamel history, on the exact model below, sold by Amazon, the brand or an authorized seller. A “% off” badge measured against a list price nobody pays is not a deal.
Why it’s worth watching: Small enough for travel, dorms and tiny bathrooms. The tank is small, so expect to refill mid-session.
Model check: Philips lists the older HX3806 as discontinued and replaced by the HX3826. Check the model number on the listing.
Wirecutter’s portable pick in our guide.
AquaSonic Precision
Verdict coming the week of Nov 20. Pre-sale read (Nov 12): We could not lock an Amazon listing for the Precision on Nov 12, so we have no price history. Paste the ASIN of the listing you choose into Keepa or camelcamelcamel before you buy.
What a real deal looks like: a price at or near the low stretches in this item’s own Keepa/camelcamelcamel history, on the exact model below, sold by Amazon, the brand or an authorized seller. A “% off” badge measured against a list price nobody pays is not a deal.
Why it’s worth watching: Wirecutter calls it the best water flosser under $50 it has tested. A good stocking stuffer or travel backup.
Model check: AquaSonic sells several look-alike cordless flossers on Amazon, including the older Aqua Flosser. Confirm “Precision” in the listing title.
Wirecutter’s budget pick in our guide (August 2026).
Fake water flosser deals to ignore
- The Aquarius “Black Friday price” that only undoes October. Keepa shows it was much cheaper in early October and last holiday season than on Nov 12.
- Two-pack and tip bundles. Waterpik bundles with a second flosser or extra tips look like big savings against list price. Compare the price per flosser with the single unit’s own history.
- No-name cordless flossers with huge “% off” badges. Wirecutter’s picks are the ION, Aquarius, Sonicare 3000 and AquaSonic Precision; a discount does not make an untested model one of them.
How to check any water flosser deal yourself
- Copy the ASIN from the listing and paste it into Keepa or camelcamelcamel.
- Use the one-year view. For the Aquarius, compare with early October and last December, not with list price.
- Confirm the model name and number (ION, Aquarius WP-660 family, Sonicare HX3826).
- Check the seller. Stock gaps bring in third-party sellers at higher prices.
Recalls to know before you buy
We re-checked the CPSC Recalls API on November 12, 2026 (latest release: November 5). We have never found a CPSC recall of a water flosser or oral irrigator from any brand, including Waterpik, Philips and AquaSonic (we searched all 3,745 notices since 2015 on Nov 11 and re-checked 2025–2026 on Nov 12). The main safety rule is the usual one for anything that mixes water and a charger: follow the maker’s charging instructions.
