Jorllina 2 Pack Replacement Main Brushes for Roborock S6 MaxV, S6 Pure, E4, S4, S5 Max, S50, S51, E25, E35, E2, C10 - Easy Clean Detachable Brush Accessories

Easy to replace, fit my model perfectly, and I can tell a big difference in an old brush versus the new one. I also think this brush is fluffier than the one that came with it when I originally bought it

The brush installed easy inside my S6. The first time using my in Roborock I did receive an error code 5. I rechecked the brush and everything was fine, so I reran the Roborock, it has been running fine since. I would like to add that I tried to buy the official replacement brush but it wasn’t in stock. After not being able to tell the difference between this brand and the other third party main brush replacements here on Amazon, I randomly choose this brand. So far it’s looking like a great cost effective replacement.

The brush does not provide the suction so I did not rate it. The brush works great. Received an error code the first few time but I sprayed a dry lubricant on free turning end and has worked with no problems since.

Compared to the original and other replacement brush rolls I’ve used these are by far the worse. They do not last very long and I spend more time trying to clean them off than actually using them. So disappointed with the quality and will not be buying again. Such a waste of material when something that lasts longer could be made.

Was skeptical off this generic brand main brush and agonized over which of the many off brand brushes to buy. Picked the “delta” version main brush for our Roborock S4 max anticipating an issue and lo and beyond worked great. A fraction of the cost of the OEM replacement. Quite relieved. Will be our go to for replacement of the main brush.

These rollers fit my S4 Max great, but if you look at the bristle count, Jorllina versus Roborock, you'll note that the Jorllina main brush has fewer brush fibers and lower brush density. Does this mean the Jorllina main brush won't function as well as a Roborock OEM main brush? Absolutely not, it cleans just as good as the OEM brush, however I strongly doubt the Jorllina brush will last as long as the Roborock OEM brush. For the price, it's still a good value.

I had tried some other brand replacement brushes from Amazon previously and the sweeper was constantly having faults and needing attention. These brushes work as good as the original brushes that came with the machine and they also are made identically which makes cleaning easier. They were a little more expensive than the other I purchased but from my experience the added cost is well worth it.

Only reason why I gave this item 4 stars is because the bristles are a little more stiffer than the genuine stiff or the bristles better the grooming of your carpet The only reason why this item does not get five stars is it seems that these generic brush rolls for Robo rock have horrible bearings which causes squealing if you do get the generic brush roll such as this use the original genuine bearings that came with your vacuums brush roll
