Cordless Water Flosser 300ml

The Waterpik FC5240 is a battery powered oral irrigator with a 300ml detachable tank and IPX7 waterproof rating. It delivers adjustable pressure from 20 to 115 PSI through five included tips. A memory function recalls the last used mode and the unit recharges in 24 hours.

Suits travel and shower use.

Cordless operation and IPX7 sealing make it practical for travel, shower use and smaller bathrooms. The 300ml tank supports a full cleaning session without refill. Buyers who need unlimited reservoir capacity for back to back users or a countertop unit with direct plumbing should consider a different design.

Pressure range 20 to 115 PSI

The adjustable pressure span of 20 to 115 PSI determines whether the flosser can meet your cleaning intensity needs. Lower settings suit sensitive gums and first time users while the upper end targets stubborn debris and braces. Select this model if that range matches your daily routine.

Questions about this item

How can I confirm the Waterpik FC5240 is working correctly after charging?

After the 24-hour charge, press the power button for two seconds. The unit should start on the last-used mode, and you will feel water pressure between 20 and 115 PSI from the selected tip.

What does the package include and what must I buy separately?

The box contains the white FC5240 handle, a 300 ml detachable tank, five specialised tips and a USB charger. Replacement tips are sold separately when the originals wear out.

Which pressure mode should I choose for daily use with braces?

Start with the Low setting at 20 PSI and increase toward Medium or High as comfort allows. The Pulse mode adds a gentle massage action for sensitive gums around brackets.
