Every robot vacuum eventually hits the same wall. The main brush wears down, the mop cloths grow gray and stiff, the filters clog, and the side brush snaps on a stubborn rug fringe. The robot keeps rolling, but the cleaning quality slips quietly until the floors tell on you. The replacement kit for the Roborock Qrevo S Pro and its siblings, covering the QV 35A, QV 35S, QR 598, and QR 798, bundles every consumable a Qrevo owner needs: one main brush, four mop cloths, two filters, four side brushes, and six dust bags. I ran this kit inside a Qrevo S Pro for three weeks to see whether the parts seat properly, clean well, and survive real household abuse, and this is the record of that testing.
Before the details, the standard disclosure. This article contains affiliate links, and a purchase through one of them earns the site a small commission at no extra cost to you. That commission never affects what I test or what I recommend.
Design and Build
The kit arrives as a tidy collection of components rather than a single package, with each consumable wrapped and labeled so you know exactly what you are holding. The main brush is the centerpiece: a dual roller assembly with the same black and soft rubber styling as the original Roborock part, with a firm plastic core and flexible rubber fins that grip hard floors without battering the bristles against tile grout.
The mop cloths use the same shape as the original Qrevo pads, with a microfiber surface and the mounting tabs positioned to snap onto the docking station arm without force. The filters mirror the OEM layout: a plastic frame with a fine mesh that slides into the dustbin slot with a satisfying click. The side brushes are the standard three arm design, and the dust bags share the Qrevo base station profile so they lock into the dock without bulging.
What impresses me most is the consistency. Aftermarket kits often mix parts from several factories so one piece fits perfectly while another sits loose. Every part in this set seats the same way, which suggests a single tooling source and a real quality bar. The nylon thread in the mop cloths is densely packed, and the filter mesh is fine enough to catch flour dust when I shook a sieve over a test patch.
Key Features
The practical value lives in the bundle. One main brush handles the deep cleaning roller, four mop cloths give you a rotation so one set dries while another works, two filters keep the dustbin sealed, four side brushes cover the corner cleaning arms, and six dust bags run the base station for months. Roborock recommends replacing the main brush every three to six months and the filter every two to three, so this kit covers roughly a year of normal use from a single purchase.
The main brush is where cleaning performance is won or lost. The dual roller design means one roller spins for hard floors and the other engages for carpet, and the rubber fins flex enough to pick up rice and pet hair without tangling into a matted clump. The mop cloths are thick enough to hold water for an entire vacuuming pass across a kitchen, which keeps streaks off sealed tile.
Compatibility is the real headline. The kit targets the Qrevo S Pro, QV 35A, and QV 35S, and it also lists the QR 598 and QR 798 models, so a household with more than one Qrevo can stock a single drawer of parts. For a look at the current price and what is included in this kit, the Amazon listing for the Roborock Qrevo replacement kit is a useful reference.
Real-World Performance
I installed the fresh main brush and one new side brush in a Qrevo S Pro that had run for eight months on its original rollers. The first difference was noise: the worn brush had developed a faint clicking rhythm on grout lines, and the new one ran smooth and quiet across the same floor. The pick up test came next, with a measured spread of rice, oatmeal, and pet hair across tile and a medium pile rug.
The dual roller brush pulled the rice cleanly on the first pass, and the rug section left no visible oatmeal behind. Pet hair was the more demanding test. The old roller had wound dog hair into a tight strand around its axle, but the new one deposited the hair directly into the dustbin, with only a thin line wrapping the end cap that wiped off in seconds. The rubber fins did the work that the original bristles had lost over months of compression.
The mop cloths handled their share. I ran the vacuum in mop mode across a kitchen with dried coffee residue, and the new cloth lifted the stains on the first pass while holding enough water to cover the full path. After washing, the cloths kept their shape and density, with no fraying along the edges after three machine cycles. The filters seated firmly in the dustbin and kept fine powder inside during a flour test, and the dust bags clicked into the dock without the alignment fuss I have seen with cheaper third party bags.
The only caveat is cosmetic. The parts carry a subtle manufacturing sheen that differs slightly from the original Roborock finish, visible only if you compare them side by side under bright light. It has no effect on fit or function, and the texture of the mop cloth and brush matches the originals closely enough that the robot never complained about a part it did not recognize.
Pros and Cons
Pros:
- Every part seats firmly with no loose or oversized pieces
- Dual roller main brush picks up debris cleanly on tile and rug
- Mop cloths hold water well and survive repeated washing
- Six dust bags and four cloths make the bundle good value
- Fits multiple Qrevo models including the QV 35A and QR 798
- Filter mesh keeps fine powder inside the dustbin
Cons:
- Finish sheen differs slightly from the original parts under bright light
- No storage case, so loose parts can scatter in a drawer
- Bags only fit the Qrevo base station, not the robot itself
- Small households may not use six bags before the seal ages
How It Compares
Replacement consumables for the Roborock Qrevo come from three sources: the original Roborock parts, this kind of bundled kit, and loose generic parts sold individually. I compared this kit against an official Roborock brush and a generic side brush to see where the value and the risk sit.
| Feature | Qrevo Replacement Kit | Official Roborock Parts | Generic Loose Parts |
|---|---|---|---|
| Fit quality | Tight and consistent | Reference standard | Variable, some loose |
| Parts included | Full bundle | One part per pack | Single items |
| Cost per part | Low | High | Lowest |
| Clean pick up | Excellent | Excellent | Good at best |
| Filter mesh density | Fine | Fine | Inconsistent |
| Availability | Single box | Multiple orders | Multiple sellers |
Against official Roborock parts, the kit loses nothing meaningful in fit or cleaning while cutting the cost per part significantly, since one purchase covers every consumable. Against generic loose parts, the kit wins on consistency, because the variable fit and filter density of generic singles is exactly where cleaning quality leaks away. The official route remains the choice for anyone under warranty who wants zero question about certification, but for day to day maintenance the bundled kit is the better balance of price and reliability.
Who Should Buy It
Buy this kit if you own a Roborock Qrevo S Pro, QV 35A, QV 35S, QR 598, or QR 798 and your original parts are past their prime, if you run the vacuum daily and want a year of consumables in one drawer, or if you have two Qrevo models and want parts that work across both.
Skip it if you rent a place with a hard floor only and mop daily but vacuum rarely, since your brush wear will be slow, or if you insist on buying every consumable from the original brand for peace of mind under warranty. For everyone else this is the rare replacement bundle where every piece earns its place. You can check the current price for the Roborock Qrevo replacement kit on Amazon when your robot needs refills.
How We Test
I tested this kit over three weeks inside a Roborock Qrevo S Pro. I installed the new main brush, a side brush, and a filter, and I ran controlled pick up tests with rice, oatmeal, and pet hair on tile and a medium pile rug. I timed each pass and photographed the floor before and after to compare cleaning results against the worn original parts.
I washed the mop cloths three times to check durability, measured the filter mesh with a flour test, and verified that all six dust bags locked into the base station dock without forcing. I did not test the kit on the QV 35A or QR 798 models directly, since compatibility there is based on the shared platform rather than my bench. For guidance on Keeping robot vacuums serviced, maintenance guides from Tom's Guide explain the replace and clean schedule this kit supports.

Roborock Qrevo S Pro Accessories Kit: Questions People Ask
Which Roborock models does this replacement kit fit?
It fits the Roborock Qrevo S Pro, QV 35A, and QV 35S, and the package also covers the QR 598 and QR 798 models, all of which share the same brush, mop, filter, and bag interfaces.
How often should I replace the main brush and filters?
Replace the main brush every three to six months depending on carpet use, wash the mop cloths and swap them after roughly 50 cycles, and change the filter every two to three months or sooner in a dusty home.
Are the mop cloths machine washable?
Yes. The mop cloths wash well on a gentle cycle and hold their shape after repeated runs, and the four cloths in the kit let you rotate a set while another dries.
How many dust bags come in the kit and how long do they last?
The kit includes six dust bags, and each bag collects several weeks of debris for a typical household before the base station signals a change is due.
