Personal care appliance delivering adjustable, splash-free water flossing for sensitive gums and braces. With an extra-large removable tank and 30-day battery life, COSLUS Water Flosser suits busy routines and travel. Could it make daily interdental cleaning quicker and gentler than traditional string flossing?

⚡ At a Glance
  • Cleaning Power: 20 intensity levels with 1,400-1,800 pulses and 30-140 PSI, using 0.3mm+0.3mm dual-stream water technology
  • Best for: Braces wearers, people with sensitive gums and travellers needing a compact oral-care tool
  • Not ideal for: Users who prefer traditional string floss exclusively or need hands-free mouthwash integration

Four cleaning modes with 20 settings cover everyday and orthodontic care. An extra-large removable tank and IPX7 waterproof rating support portable use.


Deep plaque removal - with ultra-fine dual-stream water pulses

Dual-thread 0.3mm+0.3mm water pulses operate at 1,400-1,800 pulses per minute and 30-140 PSI, producing a focused cleaning stream. US dental professional certification is noted for the pulse technology.

Focused dual-stream action reaches between teeth and around brackets to loosen and flush away plaque, making interdental cleaning more thorough than rinsing alone.

Gentle gum care and orthodontic cleaning - with four customised modes

Four modes each offer five intensity settings: Jet (splash-proof), Clean, Soft and Orthodontic, allowing fine pressure control for sensitive areas. Orthodontic tip and periodontal tip are included for targeted use.

Soft and orthodontic modes reduce irritation while still cleaning effectively, so sensitive gums and braces receive careful, consistent care.

Travel-ready convenience - thanks to long battery and removable tank

Rechargeable battery delivers up to 30 days of use after a two-hour USB-C charge, while the extra-large removable tank gives around 90 seconds of continuous cleaning per fill. Compact, palm-friendly sizing suits a toiletry bag.

Extended battery life and a single-fill runtime mean fewer charges and refills on trips, making daily oral care straightforward when away from home.
