Should you prefer the slightly more minimalist approach of a double chainring setup over a triple while still looking for a broad gear range, then the BIG.SEVEN 60 (2x) might be the right one for you. It combines a double butted aluminium frame with a more comfort-focused geometry providing you with the perfect 27.5" wheeled hardtail for long off-road outings and fast blasts through the urban jungle. A 100 mm suspension fork from RockShox and hydraulic disc brakes improve comfort and control even further.
The alternative to our BIG.NINE 29er hardtails for riders who prefer the smaller 27.5"" wheels. The latest aluminium frame generation of our BIG.SEVEN TFS and SPEED mountain bikes featuring slim tube shapes create a new look and a more relaxed geometry. A shorter top tube and a higher head tube offering a more upright riding position and enhanced trail visibility.

Solid Kit That Saves You Some Money
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I ordered this accessories kit for my Roborock Saros 10R mostly because I didn’t feel like spending a ton just to keep up with teh normal maintenance. After using it for a bit, I can say it’s been doing exactly what I hoped it would. First thing you notice is the cost of course, keeping these robot vacuums running can add up fast, and this kit really helps take the sting out of replacing the usual wear parts. Most of the pieces line up with the Saros 10R really well. Everything went in without a fight and once installed, it all works the way it should. Brushes rotate fine, filters sit where they’re supposed to, and nothing feels janky or poorly sized.
Quality wise, it’s pretty close to the name brand stuff. You can tell there’s a small difference if you really look for it on some parts. Some of the plastic feels a bit lighter and a couple items don’t have that same premium feel. But in use, I’m not seeing much of a difference, cleaning performance is still strong and the vacuum hasn’t skipped a beat.
Durability is the one thing you can’t fully judge right away. So far though, everything seems to be holding up nicely. No fraying, cracking, or early wear, so I’m cautiously optimistic they’ll last about as long as the originls.
Overall, this kit is a good deal for the money. It does what it’s suposed to, saves you some cash, and keeps the Saros 10R running smoothly. Not perfect, but definitely worth it. Four stars.

most can fit saros 10, but not all
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I should have done a little more research with these. I purchased this for a Saros 10, i thought the Saros 10 and 10R was basically the same besides the filters. I was wrong. Although the brushes are the same size, they didnt fit. They lacked a special metal piece on one side, and the 10R has a different shape on the other, cant even jerry rig it to fit. The filters didnt fit my Saros 10, but that didnt cause the dropped rating, but they quality of it looks very good, and seems well made. The side brushes are good and they fit my Saros 10, replaced them and didnt have a problem. The bags also fit and they are very good. The mopping brushes did not fit, but it was very well made and definitely wasnt just a cheap set. The brush and screw driver were just to add additional number counts and basically useless.

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.
