Reliable Replacement Parts That Work Well
Color: Saros 10r-20/Qrevo Curvx Accessories
These replacement parts have worked very well with our machine so far. The fit was accurate, installation was straightforward, and everything lined up the way it should without needing any adjustments.
Performance has been just as good as the original parts we were replacing. Once installed, the machine operated normally, and I haven’t noticed any issues with function or compatibility during regular use.
Overall, this is a dependable set of replacement parts to keep on hand for routine maintenance or unexpected breakdowns. Having extras available makes repairs a lot easier when something eventually wears out or needs to be swapped.

Solid replacement kit for the Roborock Saros - everything you need in one pack
Color: Saros 10r-20/Qrevo Curvx Accessories, Color: Saros 10r-20/Qrevo Curvx Accessories
Everything in this kit fits my Roborock Saros without any issues. The main brushes, side brushes, mop pads, filters, and dust bags all installed the same way as the originals, and nothing felt loose or off. The kit comes with a lot of parts too, so I have plenty of spares to work through before needing to reorder anything.
The quality on the individual pieces looks good. The main brushes feel solid and the rubber fins on them look well formed. The mop pads have a dense microfiber texture on one side and a rougher scrubbing surface on the other, and they feel comparable to the OEM pads. The dust bags are the sealed filter bag style with the gray plastic collar, same as the stock ones, and the filters look like they have the same fine media as the originals. Overall this is a good replacement kit if you have one of the compatible Saros models and want to stock up on all your consumables at once.

Fully Functional Replacement Set
Color: Saros 10r-20/Qrevo Curvx Accessories, Color: Saros 10r-20/Qrevo Curvx Accessories
This 28-pack accessories kit is a highly functional and convenient option for maintaining your robot vacuum. It comes fully loaded with all the essentials, and every single part—from the main brushes to the mop pads and dust bags—fits the Saros 20. In terms of daily performance, the pieces work exactly as advertised, capturing dust and mopping floors effectively to keep your cleaning routine on track.The only drawback is that the material quality is not quite as good as the original brand-name parts. The plastic on the brushes and the fabric on the filters feel a bit thinner, meaning they may not last as long as the originals before needing another swap. However, given the sheer volume of pieces you get for the price, it remains a reliable, budget-friendly choice that gets the job done.

Excellent fit and value - recommended buy
Size: 3+12+12+2+1 pack
I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake.
Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha.
I can recommend getting this kit for your robot vacuum, if it's the right set for your model.

Good option for an aftermarket replacement solution.
Size: 3+12+12+2+1 pack
I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.
