Compact Oral Care for Home and Travel

The Coslus C51 is a cordless water flosser with a 300ml tank and ADA acceptance. It weighs 0.358 kilograms and measures 14.33in W x 12.83in H x 9.06in D. The rechargeable battery requires 24 hours to reach full capacity. Built-in nozzle storage keeps two tips organised inside the unit.

Suited to Families and Mobile Users

Three modes and six pressure settings create 18 combinations for children, seniors, brace wearers and adults wanting deeper cleaning. Jet mode uses a press-to-clean function that limits splashing for beginners. Buyers who need a countertop unit with a larger reservoir or continuous mains power should consider other designs.

300ml Tank and 20-130 PSI Range

The tank holds enough water for a full session without refilling. Pressure spans 20 to 130 PSI with a ±10 tolerance, covering gentle rinsing up to orthodontic debris removal. A 24-hour charge supports multiple daily uses before the battery runs out.

Questions about this item

What type of power source do I need to charge the Type-C cable?

You need a compatible Type-C power source such as a USB-C wall adapter or power bank; the charging adapter is not included.

Will the 20-130 PSI pressure range damage older dental work like crowns?

The 18 combined mode and pressure options include gentle settings suitable for sensitive gums and existing dental work, while higher settings target braces and deep cleaning.

How do I confirm the flosser is ready after the initial 24-hour charge?

After charging for 24 hours, fill the 300ml tank, select a mode and pressure setting, then press the power button to verify water flows from the nozzle.
