Review on 🔧 Complete Replacement Parts Kit for Eufy RoboVac 11S, 30, 30C, 15C, 12, 35C - Includes 8 Filters, 8 Side Brushes, 1 Main Brush, 1 Pre Filter, 1 Rolling Brush Guard by Rebecca Massey

parts were of high quality. I have replaced sweepers, roller brush, roller brush plate and filter. However, when my vacuum cleaner started to work, it was much louder than usual and also made a rattling noise. I've narrowed the rattling down to a roller brush. I could make sounds by moving the brush back and forth while it was in the case. The vacuum also had trouble going in reverse when I tried to operate it manually with the remote control. It worked great and was much quieter until I replaced the roller brush and sweepers. Obviously these fakes are not as good as the original components. Not sure which parts contributed to the problem but I am returning them for a refund and have ordered a genuine Eufy replacement kit instead.
