Great for stocking up!
Size: 26 Pcs for Roborock Saros 10R
I bought this as I got a new one month old Roborock 10r. Comparing these with the original, the feeling of the products (the roller brushes, the filter, and the bag) feel the same. These supplies should last six months or so, so the price is good for the value. The tip I will give is when changing the mop, PULL THE EXISTING ONE SLOWLY! There’s cheapish adhesive from the factory and can easily come off the Roborock.

Love the quality and the price.
Size: 26 Pcs for Roborock Saros 10R
Loved that I don’t have to buy the expensive things from Roborock. This works perfectly for my vacuum and very similar quality as the original.

Eufy 11S Max Replacement Parts Work Well
Size: 20 PACK
For the 11S Max, the parts fit great. Changing out the parts is easy, and the parts are durable. I like that this kit has a new filter for everytime you change out the rotating brushes. Changing out the parts make the eufy vacuum cleaner function better everytime. I can’t tell a difference in the noise level when changing out the parts. Overall, thus is totally worth the money to keep the Eufy running in its best shape.
