I was very happy to find a replacement kit as it seemed better than ordering each part individually. The side brushes are fine and the filters are fine and there are plenty of them for future replacement, but the brushroll keeps getting stuck. About 5 out of 7 cycles I get a notification that something has interrupted the vacuuming and each time it seems like the roller brush is really stuck, like it's too big for the space to spin. Today I ordered the original Shark roller brush. No more fakes for me.
