Top complaints

Waterpik Aquarius Countertop Water Flosser

  • Pump quits after about a year

    Amazon's review summary says durability gets negative feedback, with multiple customers saying the pump stops working after about a year. Wirecutter says there are more reports of it breaking down or getting caked with mold than it would like, though it found the unit reliable in long-term testing.

  • Harsh stream and noisy motor

    CNN Underscored found its flow powerful but much harsher than the ION's and its motor very noisy, so it didn't pick it. Electric Teeth found the noise pretty average, at up to 72 dB, despite Waterpik's ultra-quiet claim.

  • Bulky and tied to an outlet

    Wirecutter says it takes up more counter space than its other picks, partly because of the bulky power cord, and has to stay plugged in. CNET calls it the largest model on its list. Electric Teeth notes there's nowhere to stow the excess cable.

Philips Sonicare Countertop Power Flosser 3000

  • Breaks within months

    Amazon's review summary says reliability is mixed and durability is a concern, with units breaking after 3 months or burning out after 6. It also says shoppers consider it not worth the cost. 13% of ratings are 1-star.

  • Fixed nozzle and pricier refills

    Electric Teeth notes the nozzle doesn't rotate and replacement nozzles cost about $7.50, roughly $2.50 more than Waterpik's. The warranty is 2 years, one less than Waterpik's.

  • Slides around and sprays until docked

    Electric Teeth found the unit slipped on the counter when buttons were pressed and the smooth dial was hard to turn with wet hands. Water keeps spraying until the handle is docked, and the hose sometimes doesn't coil back.
