Portable 2-in-1 Oral Care Kit

The COSLUS W40 combines an electric toothbrush and a water flosser in one compact kit. It targets users who want both brushing and interdental cleaning without buying separate devices. The 300ml water tank supports extended flossing sessions. USB charging and IPX7 waterproofing suit travel and bathroom use.

Sustained Daily Performance

The toothbrush delivers 42000 strokes per minute across four modes for consistent plaque removal. The flosser uses ultra-fine dual-line pulse technology across three modes with four jet tips. Battery life reaches 45 days for the brush and 30 days for the flosser per charge. Auto shut-off protects the motor during long sessions.

Upgrade From Separate Tools

This combo replaces a standalone electric toothbrush and a countertop water flosser. The jump is worth it for households wanting one charging cable and a smaller footprint. It is not for buyers who need a larger reservoir than 300ml or who prefer a dedicated high-pressure flosser with more tip varieties.
