A: Use a wrench or socket sized for 5/16 in. hex bolt heads; check your tool set for the matching SAE size.

Convenient Roborock Kit, but Quality Feels Lower than OEM
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
This is a convenient accessory kit for Roborock products, but my experience was mixed overall. I have a QX Revo Pro, not the Ultra, and I realized after the fact that the main brush in this kit is not compatible with my robot vacuum. That was my mistake, but it does limit how useful this particular set is for me. The kit includes a variety of parts, and it is nice to have so many replacements on hand in one package. However, the overall quality feels disappointing compared to my original Roborock accessories. The disposable vacuum bags are noticeably smaller than my OEM bags, which makes me question how often they will need to be changed. The mop pads also seem thinner and less substantial than the originals, and they do not look or feel like the same quality material. Because of these differences, I am concerned about the long term performance and durability of the replacement parts in this kit. While it is convenient and generally compatible with Roborock models, I am not confident that these accessories will hold up or clean as well as the OEM parts I am used to.

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
Color: 12PCS side brushes for Freo X Ultra/Freo Z Ultra/Freo X Plus
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.
