By Editorial Team | April 2026
If you want better interdental cleaning without giving up half your sink space, the Waterpik Cordless Advanced 2.0 is the sensible buy. It’s the best balance of portability, brand trust and everyday usefulness, even if the tiny tank stops it short of countertop-class performance.

Best overall: Waterpik Cordless Advanced 2.0
Waterpik Cordless Advanced 2.0 — £69.99
This is the right answer if you want a water flosser that actually fits real life: small bathroom, awkward storage, travel bag, shower shelf. The score is 7.7/10 because it gets the important stuff right without pretending a cordless unit can match a countertop tank.
Why we picked it:
- Three pressure settings give you enough range to go gentle around sensitive gums or stronger on stubborn debris.
- The 7 oz / 210 ml reservoir is enough for a focused clean, and the waterproof body means shower use is genuinely on the table.
- You get four tips in the box, plus a rechargeable lithium-ion battery and about a 4-hour recharge time, so it works as a daily tool rather than a faff.
The trade-off: the small tank is the limitation, not a footnote. If you like to do a slow, thorough whole-mouth pass, you’ll be refilling faster than you want.
If you want the category leader’s cordless option, buy the Waterpik Cordless Advanced 2.0.
Best upgrade: Philips Sonicare Cordless Power Flosser 3000
Philips Sonicare Cordless Power Flosser 3000 — £79.99
This is the step up if your priority is a quieter, more polished cordless experience and you’re willing to pay a bit more for it. Electric Teeth consistently praises Philips’s cordless model for being quieter than comparable water flossers, and that matters if you floss early, late or in a shared flat.
Worth it if: you want a premium-feeling cordless flosser and care more about comfort and refinement than squeezing out the last bit of tank efficiency.
Best budget pick: Waterpik Cordless Pulse
Waterpik Cordless Pulse — £35.99
This is the cheaper Waterpik for people who just want to get flossing done without overthinking settings, accessories or design extras. You give up the Advanced 2.0’s extra pressure level and larger tip set, but you still get portability, shower-safe use and the brand most buyers recognise.
Worth it if: you want a decent cordless water flosser for travel or occasional use and the lower price matters more than a bigger feature list.
How we chose
We looked at the features that matter most for a cordless water flosser: reservoir size, pressure control, battery convenience, waterproofing, included tips and daily usability. We also checked expert review consensus from sources like Electric Teeth, Which?, and recent UK roundups to make sure the upgrade and budget picks are real, available alternatives worth comparing.
Frequently asked questions
Is a water flosser better than string floss? Not for everyone, but it is easier to stick with if you have braces, crowns, bridges or tight back teeth. If string floss never quite gets where it needs to go, a water flosser is the practical fix.
Why spend £69.99 on the Waterpik instead of buying a cheaper cordless flosser? Because you’re paying for reliability, fit and the Waterpik name, not just a motor and a tank. Cheaper models can be fine, but this one is the safer buy if you want fewer compromises.
Do you need to refill the tank mid-use? Sometimes, yes. The 7 oz reservoir is the main limitation, so heavier users or anyone doing a meticulous full-mouth clean may need a second fill.
