Good spare parts for the vacuum robot 360 S5. The filters fit perfectly in the dust box, although the rubber gasket is a bit thicker on the outside so it's a bit tighter than the original. The only real issue is that the main brush isn't fully compatible with the S5. You have to pull one end with the small square nub of the original brush (it pulls out easily) and insert it into the replacement (protrusion on replacement is slightly larger). Not critical, but should be stated in the product description. Basically I am satisfied with the goods.
