My powerbot r7070 makes a loud rattling noise when it runs. Its so loud you can't hear anything else! It seems to only make this sound when the brush is in. When I take it out it seems to operate normally. How can I fix this? The warrenty expired earlier this year and it is only alittle over a year old. Will I need to get it serviced? Do I need a new brush? Please advise. Thank you.
Thank you for the link. I took the brush out and cleaned it very well along with the tray that the brush sits in. The brush is fully in tact with the rubber piece this link metions. After putting it back together and turning it on, it still makes the same loud rattling sound.
