Review on JoyBros 25-Pack Replacement Parts Set Compatible for Eufy RoboVac 11S, 15C, 30, 30C, 35C, 25C, 12, 15T, 35C - Primary Filters, Side Brushes, Roller Brushes, Guard by Heather Johnson

If your Eufy 11s needs to be replaced, please choose another brand not suitable. They are 3-5 mm longer than necessary. I'll probably try cutting/sanding them to get them working. If not, I throw them away. However I would not recommend buying this kit of parts from this brand as you are paying for 2 roller brushes that do not work. The brush case seems to fit. I think it will stay, but it seems a bit big. The filters fit. It seems like they work fine. The brushes also worked without any problems. My brushes from another brand fell off while vacuuming. I hope they don't have the same problem. I didn't have to replace the plastic filter so I don't know if it will fit.
