Perfect set of replacement parts! Virtually identical to original OEM parts....!
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
These brushes, filters, and replacement bags fit our Saros 20 perfectly! Honestly, can't tell the different at all between these and Roborock's pricier first party brushes and filters. We got our robot just a few weeks ago, and the brushes snagged on something sharp and broke. We just dropped in the replacement brushes and up and running instantly. They clean as well, and maybe even slightly better than the original brushes, which is awesome. The extra vacuum bags are also really sturdy, and seem to be made with really strong woven fibers. Overall, really high quality materials, and build quality seems really solid, would recommend 100% to anyone looking for alternative replacement parts to first party OEM parts!

Works Perfectly

The side brushes work perfectly in my robot vacuum and mop and are a better price than the brand replacements. I'm happy with my purchase.

Fit Great, Nice Replacement at a Low Price
Color: 12PCS side brushes for Freo X Ultra/Freo Z Ultra/Freo X Plus
Our Narwal robot vacuum needed some replacement side brushes and these seemed to fit the mark. They went on fine and are working great. 6 pairs for under $20 felt like a good price point.
