Is the HX3711 cordless?

Yes. It runs on a rechargeable battery, so there is no cord at the sink. It charges between uses.

How many nozzles come in the box?

Two irrigator nozzles are included, which covers a second user or a spare.

Is it good for braces?

Yes. A directed water stream reaches around brackets and wires where string floss struggles. Expect to refill the tank during a full clean.

How does it compare with a countertop water flosser?

It is smaller and cordless, but its tank is smaller and its pressure is lower than plug-in models. Choose it for convenience, not maximum force.

Is $74.96 a good price?

Six stores list it new, and $74.96 at Philips as of November 7, 2026 is at the low end of that spread. It is a reasonable buy at that figure.

Does it have a pressure sensor?

Yes. The pressure sensor signals when you press too hard, which helps protect gums.

Our take on the Philips HX3711

The Philips HX3711 is a cordless water flosser with a rechargeable battery, two nozzles in the box and a built-in pressure sensor that warns you when you press too hard. It is a compact, white, ergonomic unit meant to replace string floss for people with braces, crowns or tight contacts. At $74.96 at Philips as of November 7, 2026, it sits at the low end of what the six stores listing it new charge, so this is a fair entry point rather than a splurge.
