Rank #3 in Best Water Flosser 2026: 10 Ranked, and Why the Cheapest Wins
Waterpik Cordless Pulse Water Flosser, White, 450ml
Price and rating as shown on Amazon when we collected them. Both change.
The Waterpik Cordless Pulse sits at number three in this guide and in the middle on price: £35.99 against £19.97 for the cheapest model here. It comes with 1,489 ratings at 4.4 out of 5, the highest rating of the models compared at the top of this page, on a fraction of the ratings the two cheapest carry.
The number that stands out is the tank. The listing gives a 450ml reservoir, the largest figure on this list, and in the same bullet says that removable reservoir is good for 'up to 45 seconds of flossing time'. Both figures come from the same listing, and they sit awkwardly together: the biggest tank here is described as emptying in three-quarters of a minute. Everything on this page is taken from the Amazon listing and the customer ratings shown on it. We have not tested the Pulse ourselves.
How those 1,489 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.
