Hello Fred, We are happy to assist you with your inquiry about the Shark - ION™ 750 App-Controlled Robot Vacuum. We recommend that the side brushes be replaced when they are visibly worn. We hope this information helps. The Customer Support Team
Sorry, there was a problem. Please try again later.We've only had it a few weeks so I'm not certain. A few of the bristles were caught and bent when the robot tried a little too hard to clean something, but they were easily straightened, and performance wasn't affected at all. Based on the amount of use it's seen in the last few weeks I don't think they will need to be replaced very often at all.
Sorry, there was a problem. Please try again later.You should replace the brushes when they look worn, but the frequency depends on a variety of factors.
