Review on High-Quality Replacement Parts Kit for Xiaomi MiJia1 1S Roborock Xiaowa S50 S51 S55 S5 E20 E25 C10 T6 T60 T65 Robot Vacuums (5-Pack) by Wendy Mellgren

Just wanted to let you guys know that this pack of 2 replacement filters does not include the black pre-filter mentioned in other comments. HOWEVER it has a built in fine mesh that works similar to how I assume the black pre-filter works. I've used it a few times so far and found that it gets most of the dust and coarser things caught in it. fine-meshed, that's what matters. I'm sure the real filter will still get clogged with other finer particles, but perhaps this fine mesh will help keep the actual filter's durability and integrity intact. I just wanted you all to know this as I would like to know about this mesh. when I bought these replacement filters.
