iRobot Roomba 530 Vacuum Cleaner Side Brush Roomba 500 Series Side Brush - Replacement For iRobot 81501 Side Brush
I wouldn't buy this again. Would return the item to the seller if it is worth the hassle. It has a design defect in that the side brush arms are at a greater angle compared to the OEM part. Do a side by side comparison of this item with the original side brush from iRobot. The side brush arms in the replacement part are too close to the floor (once installed in Roomba) unlike the OEM part. This causes the side brush to go under a rug instead of floating on top when Roomba makes a transition from hardwood or tile to a rug lying on the hardwood/tile floor. This in turn causes the Roomba to get stuck, then back up and try a different angle and it happens too often. I went back to the OEM part and my Roomba transitions from tile to rug-on-tile easily as before.
A Bad Design Copy
I totaly agree with some of the other reviews even for the 700 series. There is an angel error in the design of this brush. This causes the side brush to go under a rug instead of passing on top when making a transition during cleaning a) from hardwood or tile to a rug lying on the hardwood/tile floor or b) when a rug is lying on top of the wall to wall carpet floor. This in turn causes the Roomba to get stuck everytime it trys to pass a rug. I will go back to the OEM part, and I advise everyone to do the same.
Hawaii Review
This product was a great item for the price. The value was good. The number of brushes, of course, improved on the cleaning. The problem with the product is that because it had so many brushes, it had a hard time transitioning from the floor to the rug. Sometimes I had to give it a little tug. This was not a problem with four brushes. I think the brushes being so many kept the roomba from being more mobile when going from floor to rug.
