What changed since our last update
We rebuilt this page. The older version carried prices we couldn't source, so we removed them. Everything below comes from the dated sources listed.
What the sources report on Waterpik Aquarius prices
The list price is steady at $100. The discount depends on the date and on Prime membership.
- June 23, 2026: Slickdeals (June 23, 2026) reported $47.49 for Prime members with free shipping against $100. The post showed the deal as expired.
- April 8, 2025: PopSci (April 8, 2025) reported $60 against $100, 40% off, at Amazon. That is a year and a half old.
- We found no Amazon price report after June 2026, and we can't confirm a lowest price.
The free Zroppix extension puts that history on the Amazon listing itself: the last 90 days of price for the exact version you have open, a BUY or WAIT verdict based on where today's price sits in that range, and an alert if you would rather wait. No account is needed to see the history.
Is the listing near $47, or near $100?
Open the Waterpik on Amazon with Zroppix and check the 90-day price range before you pay.
What Waterpik lists for the WP-660
Facts from Waterpik’s WP-660 page (read November 1, 2026). Check that your listing shows the same model number.
- Pressure: 10 settings. The page gives a flow rate of 13 oz (384 ml) per minute and 1,400 pulses a minute, but no psi figure.
- Reservoir: 22 oz, which the page says is 90 seconds of flossing.
- Tips: seven in the “included with unit” list: four Precision, one Orthodontic, one Plaque Seeker and one Pik Pocket.
- Warranty: three years, limited, with details in the owner’s manual.
- Dental association: the page says the product is approved and accepted by the ADA for safety and effectiveness. It does not give a certification number.
- Size and power: about 10.35 inches tall and 1.46 lb, with a 52-inch cord, 120V, North America only.
- List price: $99.99 MSRP.
What the numbers say
The $47.49 reported on June 23, 2026 is about 47.5% of the $99.99 MSRP, or 52.5% off, for Prime members. PopSci reported $60 on April 8, 2025. The box lists seven tips, which matters if more than one person will use it.
How to tell whether today's price is fair
We don't publish a price chart or a predicted price for the Waterpik Aquarius on this page, because we can't back one up with recorded data here. What we can give you is a method that works for any product, and the free Zroppix extension that applies it for you on the Amazon page.
- Confirm the exact version. Model year, size, colour and bundle can each change the price. Read the title and the variant selector, not just the headline.
- Open the price history. Use the Zroppix extension (90-day history on Amazon pages) or another tracker such as CamelCamelCamel or Keepa. Where Amazon shows its own price history link, use that too.
- Compare today's price with the lowest in the window. At or near the low is a fair price. A big "percent off" badge on its own proves little, as our guide to sale badges explains.
- Check who sells it. Amazon or the brand is safest. Compare against the manufacturer's own site, which may run separate promotions.
- Set an alert if the price isn't right yet, and decide on your own timeline. Nobody can tell you what the price will do next.
Work out the price you'd pay
- Prime: the June price was for Prime members.
- Model: Waterpik sells several flossers. Check the listing says Aquarius.
- Seller: check that Amazon or Waterpik is the seller.
- Tips: the listing's tips and settings vary by version.
Common mistakes to avoid
- Comparing different Waterpik models.
- Assuming everyone gets the Prime price.
- Trusting an expired deal.
- Paying a third-party markup.
Compare before you decide
