In addition, you’ll want to regularly examine the machine’s brushes to see if any human or pet hair has wrapped around them, or if any large debris is preventing them from working properly. Some brushes are better than others at not succumbing to tangled hair, but it’s a good idea to check your robot’s brushes regardless — both their main brush and any smaller, side brushes or corner brushes they have. These parts are often easy to pop off of the machine (because they do require replacements eventually) so we recommend removing each brush entirely, getting rid of any tangles or other debris attached to them and reinstalling them afterwards. If you have a robot vacuum with mopping capabilities, you’ll need to wash the bots’ mop pads too, to avoid any unpleasant smells or tracking mess around your home. Similarly, if your robot vacuum has a water tank, it’s worth washing this out regularly to keep it clean.
