COSLUS C51 Portable Water Flosser

The COSLUS C51 is a cordless oral irrigator designed for individuals and families seeking effective interdental cleaning at home or while travelling. Its ADA accepted status confirms it meets recognised safety and efficacy standards. The device suits users with orthodontic appliances, sensitive gums or anyone wanting a convenient alternative to traditional string floss. A rechargeable battery provides cordless freedom for daily routines.

Build Quality and Daily Use

The unit weighs 0.331 kilograms and features a non-slip grip for secure handling during use. Built-in nozzle storage holds two tips inside the body keeping them organised and dry without a separate case. A 300ML water tank with a wide borderless opening allows quick spill-free filling and easy cleaning. The upgraded Type-C charging port requires 24 hours for a full charge though the adapter is not included.

Pressure Range and Practical Limits

The flosser delivers a pressure range of 20 to 130 PSI across three modes and six settings creating 18 distinct combinations for varied needs. Jet mode offers a press to clean and press to stop function that helps minimise splashing for beginners. The 300ML capacity is designed for a full cleaning session without refilling. Users without a compatible Type-C power source will need to obtain one separately.

Questions about this item

What pressure range does the C51 water flosser deliver in practice?

The C51 produces 20-130 PSI across six adjustable settings, giving you fine control from gentle rinsing to deep cleaning around brackets and implants.

What physical space and power does the unit need to sit on a countertop or pack in a bag?

It measures 14.33 in wide, 12.83 in high and 9.06 in deep, weighs .331 kg, and runs on a rechargeable battery that takes 24 hours to fill via the supplied Type-C cable.

How do you charge the C51 for the first time, and what is the step users often miss?

Plug the included Type-C cable into any 5 V USB power source — no adapter is in the box — and charge for the full 24 hours before first use; skipping the full initial charge cuts runtime noticeably.
