⚡ At a Glance
  • Cleaning Performance: Adjustable pressures and a focused jet mode remove food and plaque with low splashing
  • Best for: Travellers, families, brace wearers and anyone needing tailored, gentle-to-deep cleaning
  • Not ideal for: Users who require larger tanks or more than two stored nozzles

Cordless oral irrigator with built-in storage for two nozzles and a 300ml tank. Three modes combine with six pressure settings to create 18 tailored cleaning options.


Personalised cleaning - with 3 modes and 18 pressure settings

Three selectable modes pair with six pressure levels each, producing 18 distinct settings that range from gentle to deep irrigation. Pressure is adjusted via controls that choose the strength suitable for different users.

Family members can select a comfortable intensity, from sensitive-gum cleaning to effective orthodontic care, ensuring safe daily use for varied needs.

Compact portability - with built-in nozzle storage and a lightweight body

Two nozzles stow securely inside the unit while the chassis weighs approximately 30% less than traditional models, preserving a small footprint. The 300ml tank fills and rinses easily thanks to an extra-wide, borderless opening.

Packable for backpacks or luggage and convenient for desk or dorm use, with no extra case needed and straightforward refills between sessions.

Fast post-meal refresh - with upgraded jet mode

Jet mode uses a press-to-clean mechanism to concentrate water flow for targeted removal of trapped food particles while limiting splash. The mechanism simplifies one-handed cleaning after meals.

Quick after-meal rinses leave the mouth feeling refreshed and help maintain a tidy sink area without extensive splashing.
