Waterpik vs Philips Sonicare Power Flosser

Countertop or cordless first

Format matters more than brand. A countertop flosser has a large reservoir, a mains-powered pump and a hose to the handle. It usually offers the widest pressure range and enough water for a full session without refilling.

A cordless flosser holds water in the handle and runs on a rechargeable battery. It takes less space and travels well, but the tank is smaller, so you may need to refill partway through a session. Both Waterpik and Philips sell each format.

Brand differences at a glance

The table sets out general differences between the two ranges. Check the listing for exact pressure settings, tank volume and tips in the box for any model.

Pressure settings and comfort

Both brands let you adjust pressure, which matters because you should start low and increase slowly. Waterpik countertop models typically use a dial with numbered settings. Philips models use modes and intensity levels, depending on the version.

More settings do not mean a better clean. What matters is a low enough starting point to be comfortable and enough range to increase it as you get used to the feel. If you have sensitive gums, check the lowest setting on the listing and ask your dental team for advice.

Tanks, tips and charging

Waterpik's specialist tips are one reason many dental teams mention the brand to patients with braces or implants. Philips' advantage is that it fits neatly alongside a Sonicare toothbrush if you already own one.

• Tank: countertop reservoirs hold far more than cordless tanks. Check whether the tank lasts a full session on your preferred setting.
• Tips: both brands sell replacement tips. Waterpik has a particularly wide choice, including orthodontic and implant tips. Check which tips come in the box.
• Charging: cordless models from both brands are rechargeable. Read the manual for first charge and full charge times, as these vary by model. See how long to charge.
• Cleaning: both need regular cleaning and descaling in hard water areas. See how to clean a water flosser.

What to check on any listing

Listings sometimes describe US versions, so check that the plug, voltage and instructions suit the UK. If a listing is unclear, the maker's UK website usually has a full specification sheet.

• Format: countertop or cordless, and whether a countertop unit's plug suits where you will put it.
• Pressure range: the number of settings and how low the lowest one goes.
• Tank volume: in millilitres, and whether that covers a full session.
• Tips in the box: which types, and whether specialist tips for braces or implants are included.
• Charging: for cordless models, the charger type and the battery figure the maker gives.
• Warranty: the length of the maker's warranty and what it covers.

If you already own a Sonicare or Oral-B brush

Owning a Sonicare brush does not lock you into a Philips flosser; they are separate devices. Choose whichever flosser suits your bathroom and needs. If you are buying a new brush as well, our sonic toothbrush guide and Philips Sonicare models compared cover the brushing side.

If you want brush and flosser in one unit, our water flosser vs electric toothbrush guide looks at the Waterpik Sonic-Fusion 2.0 combo.

Can I use Waterpik tips on a Philips flosser? No. Tips are designed for each brand's handles. Check the maker's compatibility list.

Is a cordless flosser powerful enough? Cordless models are designed for full use, but the smaller tank may need refilling. A countertop model suits home use if you have space.
