Inexpensive unnamed replacement parts for my vacuum robot. The reel didn't fit so the bracket had to be trimmed and trimmed to fit and rotate properly (too big/long) and the bracket was not properly shaped. In doing so, we fixed it by cutting off some plastic. But it doesn't work the best. Filters and stuff are fine, no problems. As the roller was the only thing I needed urgently (had to hand in the original before replacing) I needed to get it working and didn't have a part to compare. I love my robot vacuum cleaner. It works well with cheap parts, but not like the original roller, but the parts are cheaply made, nothing like the original parts. You get what you pay for I guess.
