Affordable Roborock Qrevo CurvX Accessories That Fit Well
Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
I have a Roborock Qrevo CurvX vacuum cleaner, so when I saw this replacement parts pack, I wanted to give it a try. The box contained everything needed to carry out the maintenance schedule recommended in the Roborock app. It even included a small screwdriver, which made changing the side brush easy — a thoughtful extra touch. I compared all of the replacement parts to the original ones and didn’t notice any major differences. Overall, the parts do seem slightly lower in quality than the originals, but not to the extent that I think it will significantly affect performance or durability. I replaced the side brush without any issues, and it fit properly. The mop pads were softer and fluffier than the originals and didn’t fit quite as snugly, although I don’t think this will have much impact on cleaning performance. The new filter installed perfectly, and the vacuum bags also fit as expected. Overall, I’m happy with this product. It’s reasonably priced and represents good value for money. I can see myself continuing to use these replacement parts in the future. I’m taking one star off due to the parts being of slightly lower quality

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.
