Price and rating as shown on Amazon when we collected them. Both change.
The Philips Sonicare Cordless Power Flosser 3000 is the number 9 pick in this guide. It is a battery-powered, cordless water flosser with a nozzle that rotates 360 degrees, two cleaning modes and an adjustable intensity, and at £62.99 it is the second dearest model on the list — £8 under the £69.99 Waterpik Cordless Advanced, and more than three times the £19.97 COSLUS. It carries 742 ratings at 4.3, against 47,762 at 4.3 for that cheaper COSLUS.
The listing's own numbers are where this one gets awkward. Philips states a 250 ml tank, well under half the 450 ml the £35.99 Waterpik Pulse claims, and then promises "a complete clean in 60 seconds" from it. The same page gives the model number as HX3826/33 while the manufacturer part number reads HX3826/35 — one of the two is wrong and the page does not say which. And the first review below calls the tank "very large", which is not what 250 ml normally means. Everything on this page comes from the Amazon listing for this product; we have not tested it ourselves.
