My Neato works just like before changing the blade brush, but now the noise it makes is completely awful. It sounds like somebody is mowing lawn inside the house...but no, it's Neato. It's the best I can describe the sound as. It used to be smooth, vacuuming sound but now it's like a war is taking place in our home when Neato does it's job.
This started after I replaced the blade brush and the filter. I assembled everything like they're supposed to be (watched a video too), and I don't see anything being out of place. When I inserted the blade brush, I made sure the black thingy on the left side attached to it correctly. It's doing a good job but the noise is horrible.
