Keep your iRobot Roomba operating at peak performance with this iRobot 21905 replenishment kit that features 3 sets of dual HEPA filters and 5 replacement brushes for maintaining your Roomba's cleaning power and reducing dust and allergens in your home.
Roller brushes seem to be the ones that will fail the most. Spinner no problems with them yet, so I think this should have 2 more each brushes. There were no other kits avail from Best Buy when I needed a replacement.
iRobot Roomba 770 Vacuum Cleaning Robot: The Roomba 770 Vacuum Cleaning Robot provides a concentrated clean, all at the push of a button. The 3-Stage Cleaning System with Dirt Detect Series II identifies dirtier areas in your home and focuses cleaning, ensuring Roomba tackles even fine pet hair, dust and dirt.
I have 2 Dogs and a fairly big LR area and the Roomba is doing a great job keeping it clean. I just wish it had a bigger container since I have to empty it every day. So, it is great, but I think it is still an expensive toy to have.
