Ronsit Side Brush Replacement Compatible with Roborock S6 S6 Pure S5 S5 Max S4 E4 E20 E25 E35 C10 S50 S51, Compatible with Mijia Robot Vacuums Accessories Kit,6-Pack

Once I put it on, I watch it and it work as good as the original so far.

I was honestly losing my mind trying to figure out what was wrong with my s4 for a while. I had recently moved into a new home. Deleted my maps and had my vacuum start going. It would go for a bit then do some spin moves in one spot then error out constantly. I had about 20 email exchanges with roborock customer service about it. I had tried factory resets. Multiple map deletions. New s4 side brushes new rollers.Nothing fixed it. Until I ran the vacuum without a side brush installed at all and boom it ran the whole house fine. What was the problem? Thicker carpets! Roborock suggested I purchase s5 side brushes (these) and see how they work.They work perfect! They’re not getting tangled in the thick carpet like the s4 side brushes do. Also now my robot is kind of two-toned (maybe you like it, maybe you don’t, maybe I’ll add racing stripes next.)

Since the center portion of the brush is made of rubber/plastic it is making lot of sound while brushing the floor.Otherwise no issues so far.

These work great and less expensive than the name brand ones.

Easy to add and does the job
