Everything you need for your robot maintenance
Color: Saros 10r-20/Qrevo Curvx Accessories, Color: Saros 10r-20/Qrevo Curvx Accessories
Automatic floor robots are a great convenience and, at this point, I can't picture our house without one. Being able to turn them on at night and wake up to vacuum and mopped floors is pretty amazing. The problem is that you eventually have to do maintenance on them to keep them running. I guess it's not that much to ask of you since they do go for a long time with only water refills and waste water dumps. It's hard to find kits that are comprehensive enough to cover all the needs, so when I saw this one, I had to pick it up. The kit contains multiples of every consumable on the Roborock (ours is named Mrs. Nesbit). It also comes with a screwdriver and a blade/brush to clean dirt and hair. The small spinning brush is easy to replace, and the only one you need the screwdriver for. The mopping pad functional on the Roborock is one of my favorite features, so having multiple replacements makes this kit very attractive. They simple peel off of the Velcro and lay back the same. The split rollers take a minute to figure out, but you don't need to loosen the screws - they pull right off the U shaped plastic pieces they are attached to, but keep track of which goes with which color because each plastic piece only goes back on its correct side. The easiest to replace is the filter on the dust bin in the robot since it just pops out and the new one fits in. The lasts step is to replace the dust bag in the base itself, which is very simple. Overall, the quality and fit of all the pieces included in this kit were great. I didn't run across anything that was off or I had to force on. While my pads and brushes weren't as bad as my other vacuum (named The Beast), the vacuum had been warning me that their life was coming to an end and I needed to swap them out. Now I have multiple replacements for the future and my Roborock is good to go for many months. I will be picking this kit up again when I run out and wouldn't hesitate to recommend it at this price point.

Good Budget Replacement Set, but Mop Pads Differ from Original
Color: Saros 10r-20/Qrevo Curvx Accessories
These replacement accessories fit my Roborock Qrevo S5 without any issues. I run my robot daily because I have a dog, so I go through mop pads pretty quickly and have already used this set for a couple of cleaning runs around the house on vinyl floors. The bags seal properly, and I did not notice any loss of suction or performance with the filters compared to the original parts. The biggest difference was the mop pads themselves. They feel noticeably different from the OEM Roborock ones and seem a bit lower in quality. Even so, they still got the job done for normal daily cleaning and handled pet hair and dirt well. Since the original pads also wear out for me after multiple washes, this set still feels like a practical and more affordable alternative overall.

Not as good as the oem accessories
Color: Saros 10r-20/Qrevo Curvx Accessories, Color: Saros 10r-20/Qrevo Curvx Accessories
I have a roborock saros 10r and all of these accessories seem to be compatible and work with my robovac however the quality of them isn’t nearly the same level. The mop pads material are much coarser and less fine than the original. The side brushed bristles weren’t nearly as tightly bound together. The roller brush isn’t as well made. The cleaning performance I think is similar but i suspect they will not last as long as the oem accessories which are just much better made. Over it’s a mix on value.

All the parts needed to maintain your Roborock robot, with a great fit and finish.
Color: Saros 10r-20/Qrevo Curvx Accessories, Color: Saros 10r-20/Qrevo Curvx Accessories
This is a great consumable parts replacement package for many Roborock robots. I utilized it for my Saros 10R. The parts all fit great and honestly look and feel just like the OEM parts that came with the robot. Over time, I have purchased new consumable parts for my Saros 10R from various sources, but I think that I will be using this kit in the future. The kit comes with everything one needs to maintain Roborock robots, as outlined in its description. The main brushes are of good quality and fit well. I have found that the main brushes and the filter fit are the hardest things for third-party vendors to duplicate, and these do that well. What I like most is the mop heads. They are of very good quality and may be better than the OEM mop heads. Everything in this kit fits well and mimics the manufacturer's parts closely in both quality and fit. Compared to the cost of Roborock OEM parts, this is a home run.

Nice Value Replacement Kit for the Qrevo CurvX, Brushes Slightly Less Dense Than OEM
Color: Saros 10r-20/Qrevo Curvx Accessories, Color: Saros 10r-20/Qrevo Curvx Accessories
All of the included items fit my Roborock Qrevo CurvX nicely, and the material quality is fairly close to the OEM parts. I also liked the quantity of each item included, since it should be quite a while before I need to buy another replacement kit. The only downside I noticed was that the main roller brushes have about 1/4 fewer bristles than the OEM versions, so they don't seem quite as dense. Other than that, everything fits as expected and the kit seems like a solid value for maintaining the CurvX.
