Summary

A 3-setting cordless water flosser with a 7 oz reservoir, four tips and a sealed battery, waterproof for shower use. Plan on the battery deciding how long it lasts: owners report the unit dying at about 2–2.5 years, and it is not replaceable.

Strengths

  • Picked as the best overall cordless flosser in Electric Teeth’s hands-on testing.
  • Three pressure settings, four included tips and mode memory.
  • Easiest tip rotation and the best comfort and balance in that test.
  • Shower-safe and travel-friendly, with a bag, travel plug and tip case in the box.
  • Consumer Reports lab-tested the 2.0 for noise, charging, capacity and ease of use.
  • Two-year warranty and an ADA-acceptance claim.

Weaknesses

  • The sealed battery is not user-replaceable; owners report the unit dying at about 2–2.5 years.
  • Charging faults are the most repeated complaint, from blinking indicator LEDs to corroded magnetic contacts.
  • Claimed 4-hour charge; the tester and Waterpik’s own FAQ say about 8 hours.
  • No timer or pacer to pace your technique.
  • The magnetic charger is bulky and no wall adapter ships in the box.
  • All-plastic build, including the chrome-look trim.

Which model this is

Two generations share the Cordless Advanced name and are not interchangeable. The original WP-500 series (WP-560 white, WP-562 black, WP-563 blue, WP-565 orchid, WP-567 gray, WP-569 white/rose gold) used a sealed NiMH battery, a 2-pin charger and about a week per charge. The 2023 Cordless Advanced 2.0 (WP-580 white, WP-582 black, WP-583 blue, WP-587 gray) moved to a lithium-ion battery and a magnetic USB-A cable with a claim of up to 4 weeks per charge.

The listing’s ASIN is B09WVLDG75; because old and new stock pool under one title, confirm the model number on the bottom of the handle.

Battery and charging reliability

This is where the model earns its caution. Charging itself is the other weak point. A second thread shows the magnetic charger briefly lighting the pressure LEDs then going dark, and a Best Buy Q&A reply flags magnetic contacts that corrode and need polishing, with Waterpik advising a recharge after every 6–8 reservoirs. Waterpik’s FAQ tackles weak pressure with a 5-second Mode reset and a 1-hour charge. Charge time is slower than the marketing suggests: the page says 4 hours, but Waterpik’s own FAQ and the hands-on test both say about 8.

Pressure, tank and handling

Testing measures the range at 45 PSI low and 75 PSI high, with 1250 pulses a minute and about 70 dB of noise. The 7 oz (207 ml) reservoir runs 45 seconds on high and 65 on low, enough for most mouths without a refill. Tip rotation is the easiest the tester had used, grip and balance drew praise, and there is no timer or pacer. The build is all plastic, and the power button sits where it is easy to switch on by accident.

Repairs, parts and running costs

Nothing electrical is user-serviceable. The battery is sealed, and the parts actually sold are the consumables: replacement tips every 3–6 months, a $14.99 replacement reservoir for the WP-560 and WP-580 series, a tip storage case and an optional USB wall adapter that is not in the box. Monthly cleaning is a 1:2 vinegar-and-water soak of the tip and handle plus a run-through of the same mix; weak pressure is fixed with a 50/50 warm-water-and-vinegar deep clean. Electric Teeth estimates ownership at roughly $110 over 3 years at the about $90 street price.

Is it worth it?

At the promotional $54.99–$69.99 it is the obvious pick of Waterpik’s cordless line. Consumer Reports lists it from $85.98, Waterpik and Walmart list it at $99.99, and the hands-on reviewer puts the average street price near $90. Around $90 it still works if cordless shower use and the travel kit are what you want. Above $100 the sealed battery’s roughly 2–2.5 year life argues against it.
