Value replacements
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
As far as I can tell these are pretty solid replacements for the SAROS 10R. My original side brush was all torn up after just a few months of use so I found these replacement parts. Haven’t used the mop pads yet, but they are a similar design to the “upgraded” mop pads offered by Roborock which are superior to the standard one IMO. Everything else seems to be equal quality to the OEM parts, and at less than $12 I have no complaints on this kit.

Does not work for Qrevo Arc.

Filter does not fit my Qrevo Arc. Photo shows size comparison between my old (very dirty) filter and the replacement filter.

Solid replacement parts kit — just skip the mop pads
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
This kit has been a handy all-in-one refresh for my robot vacuum. The main brush, side brushes, filters, and dust bags all fit correctly on my Qrevo, slid in without fuss, and have been performing on par with the originals — suction feels unchanged, the side brushes kick debris toward the intake properly, and the filters look and seat identically to the ones they replaced. My one real complaint is the mop pads. They're noticeably thinner and flimsier than the OEM pads, don't hold water as well during a run, and left streakier lines on my floors compared to what I'm used to. I've ended up going back to the original-brand mop cloths and just using this kit for the dry-cleaning parts, which have genuinely been a good value. Four stars — great kit minus the mops.

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.
