Do aftermarket parts void my robot vacuum warranty?

Technically, manufacturers cannot void your warranty solely for using third-party parts (Magnuson-Moss Warranty Act). However, if a third-party part causes damage, that specific damage would not be covered. In practice, manufacturers rarely investigate part origin.

How do I know when to replace parts?

Replace filters when suction noticeably drops even after cleaning. Replace side brushes when bristles are bent or worn. Replace main rollers when they show visible wear or the robot makes unusual grinding sounds.
