Update side brushes garbage. Looking at this kit for just the brand name brushes will save you money in the long run. We'll be in the third set since the first check. This last set took about 3 weeks and has very few bristles left and is said to be 90% full. Side brushes are ok, filters are ok. But the big problem here is the main brush roll. It doesn't fit the size. The Ecovacs brush fits snugly, this one doesn't. Why that sucks because when cleaning you can hear it rattling up and down which makes Ecovacs very noisy. Also, one of the brushes had a broken tongue that was supposed to fix this roller. Although it has this function, its dimensions are not suitable to fulfill its task. You can see in the picture that the OEM is slightly larger.
