Compact oral irrigator with IPX7 waterproof rating. - Brand: ROAMAN - Model Name: Mini-1 - Waterproof Rating: IPX7 - Power Consumption: 8W - Accessories: Charging cable, storage bag, instruction manual - Other: Water flosser nozzles Thank you for viewing. This is a used item. It wasn't used much, but it's rechargeable and portable, making it recommended for those undergoing orthodontic treatment or those with misaligned teeth. One nozzle is unopened. Since you replace the pink ring to use it, I've included a disinfected used one as a sample. Please discard the old nozzle after replacing the ring. Please check the photos for the slight stains on the included drawstring bag. I thought it was convenient that it could be used for about a month on a single charge. You extend the main body to use it, but it's not smooth and requires some force. It seems to be designed this way originally.
