A soft-bristled nozzle front and gentle water pressure are designed with children’s cleaning in mind. The water stream helps rinse teeth after meals and supports an everyday oral-care routine. The unit also has a smart memory function, while its textured, non-slip back helps children hold it securely. To change the pressure mode, hold the power button while the flosser is off until the indicator flashes, then select the desired setting.
Who it’s for
The C31 is intended for children aged 6 and up, with pressure levels labelled for different age groups. That gives families a way to choose a setting suited to the child, while the medium mode offers another option. The compact handheld format and one-button controls keep the routine straightforward, and the 150 mL tank means less frequent refilling during a cleaning session.
For families weighing a water flosser against string floss, this model offers a water-based approach that children can use as part of daily cleaning. Buyers commonly highlight its ease of operation and refilling, and some find water flossing easier to manage than regular floss. Feedback on changing pressure settings is mixed, and some buyers report durability concerns, so those experiences are worth considering alongside the product’s child-focused controls.
Box contents
The package includes two jet tips and customisable stickers, so children can personalise the flosser. It is rechargeable and reaches a full charge in about 2.5 hours. A charging adapter is not included, the manufacturer says it can be charged with a 5 V adapter. Its IPX7 waterproof rating makes it suitable for bathroom use.
When it makes sense
This flosser fits a daily routine where a child needs a simple way to rinse around their teeth, including after meals. At home, the tank capacity supports a cleaning session with fewer refills, while the lightweight, portable design is also practical for school or travel. The included stickers can make the device feel more personal and help invite children to take part in their routine.
It’s also suited to households looking for a rechargeable option rather than a flossing tool that relies on string. The manufacturer states that a full charge supports up to 30 days of use, making it convenient to keep ready between charging sessions. For children starting water flossing, the age-labelled settings, gentle-flow design and straightforward controls give the COSLUS C31 a clear role in everyday oral care.
