Is the Waterpik Cordless Pulse 3100 worth it?

At $29.99 at Amazon as of November 4, 2026, it is a low-cost way to try water flossing or to get a travel unit. If you floss at home daily, a countertop model with a larger reservoir will need fewer refills.

How does it compare with the Cordless Pulse 3200?

The 3100 has two pressure settings and a 6 oz reservoir. The 3200 adds a third setting and a slightly larger tank, so it costs more but needs fewer refills.

How long does the battery last per charge?

Waterpik rates it for up to 9 weeks of use per charge. Actual time depends on how often and how long you floss; heavy daily use will drain it faster.

Does it come with a charging cable?

It charges over USB-C at 5.0V up to 3.0A. The box includes two flossing tips; check the listing for whether a cable or wall adapter is included.

How much water does it hold?

The reservoir holds 6 oz, about 45 seconds of flossing. Expect to refill once or twice for a full session.

Only one new listing is tracked, $29.99 at Amazon as of November 4, 2026, so there is no recent low to wait for. Watch for holiday sales, when Waterpik units often drop.
