Check the condition of the brushes and replaced them if they are worn out;
Check the wear of the brushes: the minimum diameter shall not be less than 115 millimeters;
Check that there are not any wires, plastic threads or any other material which are tangled with the brush
Every 40 – 50 hours make sure to switch the front brush with the rear brush to even out the wear so they can last longer
CLEANING THE DETERGENT SOLUTION FILTER

supposed to be clean, in addition there is a filter in the mouth of the tank that filters the water
Follow the instructions below to clean the filter

brake;
