Wirecutter's budget pick and CNET's top cordless: about $39 for power on par with the Philips cordless, plus a bigger 290 ml tank. It is heavy and harder to grip and clean, can't take mouthwash, and some Walmart buyers report leaks.
Top complaints
- Hard to clean, with grime-collecting crevices
Wirecutter found two separate openings and extra crevices where grime and mold can collect, and the tank isn't dishwasher-safe. A 2-star Walmart reviewer says water gets trapped behind the tank and grows mold, even on a replacement unit.
Source: Wirecutter, Walmart reviews (lowest rated) - Heavy and wide
Wirecutter says it weighs about 1.7 pounds when full and has a wider neck, so people with smaller hands or dexterity concerns may struggle with it.
Source: Wirecutter - Leaks, dead units, stiff port cover
Walmart's lowest-rated reviews describe water spilling over the unit, a reservoir that doesn't seal, units that wouldn't charge, tips that came off, and a charging-port cover that's hard to open. One reviewer says only 3 of the 8 levels change the flow.

What owners love
- Power on par with pricier flossers
Wirecutter's testers loved the stream, comparing it to the Philips Cordless Power Flosser 3000 at about half the price, and preferred it to the Waterpik Cordless Express.
Source: Wirecutter - Big tank, long battery
CNET lists a 290 ml tank (Wirecutter says nearly 10 oz) and a 40-day battery. Walmart's review summary also highlights battery life of up to 40 days.
- QuickJet on/off control
Wirecutter says the QuickJet button lets you pulse the stream on and off, so it feels less like flossing with a firehose. CNET lists five modes and a travel bag.
