Problem:- Whenever V80 machine is switched on, it starts, goes few step and then come back and stop. 

Reason: In daily cleaning routine, sometimes a thread or some dust get stuck on bumper. Due to this 1 side of the bumper is pressed and does not come out.

Solution: ● In order to fix this, first turn off  the Machine, from the side button       

● Try to press the bumper, which is the front part of Cleaner and see if it comes out. Bumper need to be pressed from both corners and center. 

● Once you find that bumper is pushing back fine,  Please start the machine and it should work fine. This is the part of daily cleaning activities.
