After two full weeks of heavy use - running every day, sometimes multiple times a day - cleaning our downstairs, I received my first alert from the app to clean some of the components, specifically the drop sensors and the fluffer bar.
As you can see in the images, there was very little hair build up, which continues to amaze me, given the amount of dog hair that comes from our golden retriever. It was very easy to take apart the components to clean, reassemble, and reset the alarms in the app. This has been far easier to maintain compared to other robot vacuums I've owned, especially as it does not build up dog hair around the main roller or around the side arm.
