Hey guys, thanks for the response. I am aware that brushes and filters would have to be replaced. My question is, will I have to replace them every 3-4 months of light use. I doubt it even done 50 hours of work. If I replace it and it happens again it will not be financially viable for me to use that. From the outside the rotating brush is absolutely fine, there is no damage to the bristles or the rubber. I am just trying to find out if anyone else had such issues. Also, how often do you change brushes and filters?
