CLEANING THE SIDE BRUSH (OPTIONAL)
Careful cleaning of the side brush guarantees better cleaning of the floor as well as a longer lifespan of the gear motor present in the brush head
body. To clean the brush, proceed as follows
1. Go to the right-hand side and press the brush locking pin ( Fig.11 ).
2. Keeping the pin pressed, turn the brush clockwise until it is locked ( Fig.12 ).
