Review on LOVECO Replacement Accessories Compatible Roborock by Constance Bingham

Not sure about other models but works fine with E4. The filters may not be washable under water but they work well and you get 4 of them. You also get two main roller brushes that work just as well as the original and 4 spinners are pretty much the same, all for $27. Compare that to a real Roborock replacement and you get 1 filter, 1 roller brush and 1 spinner for $76. So apples to apples, that's a much better deal.
