3.3.4 Product charging
Connect one end of the charger to the mainframe and the other end to the
home socket (the red light is always on when charging, and the green light is
always on when it is fully charged). When charging, the whole machine shall be
placed on the charging stand, close to the wall corner, to avoid tripping and other
injuries (Note: it is best not to plug the charger into the plug for a long time, to
prevent children from touching it ,etc.).
Note: Every 3 months after the product is purchased, please use the charger
specially provided by our company to charge the battery.

Before the self-cleaning, place the machine on the tray, insert the charger into the
plug, and keep at least 1/2 of the water in the water tank. Press and hold the
speed button for 3s and enter the self-cleaning mode after the indicator light
flashes for 3s. After the self-cleaning ends, the machine will automatically shut
down, which is a self-cleaning cycle.
Note: Before using the self-cleaning function, please clean the sewage in the
sewage tank after the self-cleaning is completed
