Portable Oral Care for Home and Travel

The ROYAL IRIS C15 is a rechargeable cordless water flosser designed for daily oral hygiene. Its lightweight, waterproof build and 300ml tank make it suitable for bathroom use or packing in luggage. Users seeking a simple, battery-powered device for cleaning between teeth and along the gumline will find it straightforward to operate.

Four Modes and Nozzles Tailor the Clean

The unit includes four adjustable pressure settings: Soft for sensitive gums or first-time users, Normal for everyday cleaning, Strong for deeper plaque removal, and Pulse for gum massage. Four included nozzles allow multiple users or specific needs such as orthodontic care to be addressed without sharing tips. A simple button cycles through modes before each session.

300ml Tank and 60-Day Battery Headroom

The 300 millilitre reservoir holds enough water for a full cleaning session of up to 90 seconds. A full charge takes approximately 4 hours and delivers up to 60 days of typical daily use, reducing the need to carry a charger on short trips. The 1800mAh battery and USB-C cable support charging from power banks or laptop ports, though very high-pressure use will shorten the interval between charges.

Questions about this item

How often will the rechargeable battery need to be replaced after the 60-day cycle life?

The built-in 1800mAh battery is not user-replaceable; after many charge cycles the whole unit would need service.

Which mode reaches the pressure limit first during a continuous 90-second cleaning session?

Strong mode delivers the highest pressure and will hit the motor's sustained-output limit before Soft, Normal or Pulse.

How much noise and heat does the low-noise motor produce when running all day on a single charge?

The motor is rated for quiet operation; it stays cool and under 60 dB even during back-to-back 90-second cycles.
