How is this different from a full-size water flosser?

It is cordless and its tank collapses over the handle, so it stores and travels easily. A full-size unit holds more water and usually needs fewer refills.

Does it come with a wall adapter?

No. The box has a charging cord but no power adapter, so you charge it from a USB port or your own adapter.

How long does the battery last?

Philips rates it at 21 days of typical use. Owners often report weeks of daily use between charges.

What nozzles are included?

Two: the N1 Standard for between-teeth cleaning and the N2 Comfort for sensitive teeth and gums.

Is it good for sensitive gums?

Yes. It has a comfort nozzle and a gentle mode, and owners with sensitive gums report no bleeding.

Can I use it in the shower?

It is a cordless water flosser meant for sink use. Keep the charging cord and port dry.
