Everything fits perfectly and installs just like the original parts
Color: Saros 10R/Qrevo CurvX Accessories Kit
it exceeded my expectations. If you own one of these models, this kit is a smart and cost-effective way to keep your vacuum running at peak performance.
The value is excellent. Everything fits perfectly and installs just like the original parts. I didn’t notice any compatibility issues, and the vacuum recognized and performed with the parts flawlessly.
The main brushes are sturdy and pick up debris efficiently, while the side brushes sweep edges and corners just as effectively as the OEM versions. The HEPA filters do a great job capturing fine dust, which is especially noticeable if you’re sensitive to allergens. The mop pads are absorbent and hold up well after multiple washes.
I also appreciate having extra dust bags on hand. it makes routine maintenance simple and stress-free. The included cleaning tool is a thoughtful addition that helps remove hair buildup quickly.
Overall, this kit delivers quality, quantity, and convenience in one package. It’s an excellent investment for maintaining your Roborock and extending its lifespan. Highly recommend!

Fit My Roborock Saros 10R Perfectly
Color: Saros 10R/Qrevo CurvX Accessories Kit
I got a Roborock Saros 10R for Christmas and purchased this accessory kit to have on hand when they are needed. I have an older model Roborock and you never know when something might need to be replaced. Since the accessories for my older Roborock do not fit my new 10R I wanted to ensure that I have dust bags on hand and don’t lose precious vacuum time waiting for delivery. After shopping around I decided that this set, for the price, made the most sense for me. Not only do I get the dust bags, but I also get replacement mop pads, main brushes, side bushes, filters and tools so when it’s time to replace those items, I’m ready. Although I don’t have a need to replace all of the parts just yet, I did check each of them to make sure that they fit and that the quality appears to be adequate. Everything fit well, and looks to be a reasonable replacement. There was some slight quality differences, however, there’s nothing that is concerning, and the quality difference is so slight that it’s barely noticeable. Considering the price difference from the name brand this accessory set is an excellent bargain!
