Rinser Toothbrush is a toothbrush with a power fountain, designed to work without a motor. The stream of water leaps upwards from its center.
The heads of this toothbrush are replaceable, meaning you can keep it much longer.

“The inlet area is significantly larger than the outlet, therefore the outlet velocity is proportionally larger than the inlet velocity. This would allow the stream to shoot higher up.”
