Most likely these are tips for any robot vacuum cleaner: I don't have pets or people with long hair, so I'm not familiar with the problem of hair clogging my brushes. On the first day after the purchase, I watched how it works and what hinders it. Now I pre-clean what can interfere with the vacuum cleaner. Namely: 1. He doesn't like rags on the floor. Thin bed rugs. Long curtains that drag across the floor (get tangled) or fall into the field of view of his laser gun (will think they are an obstacle). 2. It is also better to remove the wires. 3. There is no need to specially leave garbage on the floor. Garbage compartment and so small. 4. So that the HEPA filter does not clog so much, I cut out a grid on its inner surface (I made it from mosquito window mesh). It has become easier to clean. Such a grid is on a newer model of a vacuum cleaner.
