If any special liquid will be filled in the water tank, please clean the tank 

in advance. Inject some warm water in the water tank. 
Point the jet tip to the sink. Turn on the device until the tank is empty. It 
will help avoid tip blockage and prolong the service life of the device. 
The device shall be cleaned with a soft cloth and neutral wear-free 
detergent. 
Do remember to unplug the device before cleaning. 

Take  off  the  water  tank  and  start  operating  the  oral  irrigator  until  no 

residue can be found in it. 

1. Unplug the device after cleaning is completed, place the water tank 

upside down on a plate until it is totally dry, and then keep it with the 

clean body at a cool and dry place. It shall be kept in a package or 

appropriate paper box in case of long-term storage. 

2. You may consult the distributor or call us for relevant maintenance 

methods in case of any malfunction.

responsible for the maintenance of any fault arising therefrom. 

4. If the wire is damaged, please seek help at the designated mainte-

nance point or qualified repair shops. Do not replace the charger wire or 

plug by yourself.

but a proper amount of material and service fee will be collected. 

If the battery needs to be replaced, 

please insert the battery key to the hole 

on the battery lock and switch to unlock
