The Amazon listing is the 'Cordless Advanced' WP-580, with 78,335 ratings pooled across colors (9% 1-star, 4% 2-star). Experts tested the 2.0 or an earlier version (Electric Teeth's review URL references WP-560).

The most popular cordless Waterpik, comfortable to hold with about a month or more per charge. Testers split on it: Electric Teeth and Good Housekeeping rank it best cordless, while Wirecutter, CNN and CNET found its pressure weaker or its $100 price hard to justify.

Top complaints

  • Weaker pressure than rivals

    CNN wished it delivered stronger pressure and found the Philips cordless did it better. Wirecutter says it did not perform as well as its cordless picks. Amazon's summary calls power mixed, with some owners finding it too weak, and Electric Teeth says it is less powerful than countertop models.

  • Stops holding a charge or breaks after a year

    Amazon's review summary says some owners report it stops holding a charge and units break after a year. Electric Teeth notes user feedback on long-term battery reliability, which it couldn't confirm.

  • Small tank, pricey, bulky charger

    Good Housekeeping says you may have to stop and refill mid-session; Electric Teeth timed a tank at about 45-65 seconds. CNET says it didn't stand out for its $100 full price, and Electric Teeth lists the price, bulky magnetic charger and fairly loud 70 dB as cons.

What owners love

Good for
  • A comfortable, grippy cordless handle
  • Shower use and travel (bag included)
  • Long gaps between charges

Scores (tap for why)

  • Cleaning3.5
    Why 3.5?Powerful per GH testers, but CNN and Wirecutter found it weaker than the Philips cordless; Amazon feedback on power is mixed.
  • Comfort & pressure control3.5
    Why 3.5?Three settings (45-75 PSI) with a mid-use mode button, and Electric Teeth found it the most comfortable cordless flosser to hold.
  • Tank size2.5
    Why 2.5?7 oz (207 ml), about 45-65 seconds per fill (Electric Teeth); GH warns of mid-session refills.
  • Less mess4.0
    Why 4.0?Shower-safe and rinseable (Electric Teeth, GH); Electric Teeth notes only the expected dribble.
  • Durability3.0
    Why 3.0?Electric Teeth found it well made, but Amazon's summary flags charge-holding failures and breakage after a year (13% at 1-2 stars).

What experts say

  • Electric Teeth: Best cordless (5/5 in its review): most comfortable and easy to use. Its flossing time is shorter than countertop models' and it is less powerful.
  • Good Housekeeping: Best cordless (2.0), powerful and consistent per testers; the small tank may need a mid-session refill.
  • CNN Underscored: Tested, not picked: best ergonomics and a month of battery, but its water pressure trails the Philips cordless.
  • Wirecutter (NYT): Dismissed: it found Waterpik's cordless models, including the Advanced 2.0, lacking next to its Philips and AquaSonic picks.
