If your Roborock vacuum is leaving streaks of dust or struggling with pet hair, a worn-out brush is often the culprit. Replacing the main brush and side brushes regularly keeps suction strong and prevents tangles from slowing down your robot. In this guide, we focus on the best Roborock brush replacement options for 2026, specifically two comprehensive kits from Lacvik that cover popular Qrevo models.

Whether you own a Qrevo S Pro, QV 35A, or the newer Qrevo S5V, you need parts that fit perfectly and deliver tangle-free performance. We have evaluated these kits based on build quality, included accessories, and real-world cleaning efficiency.

Buying Guide: What to Look for in a Roborock Brush Replacement

Compatibility with Your Exact Model

Not all Roborock brushes are universal. The Qrevo S Pro/QV 35A kit fits only those models, while the Qrevo S5V kit works with S5V, Curv, Edge, and S5X. Always double-check your vacuum’s model number before ordering, as an incorrect fit can reduce cleaning efficiency or damage the unit.

We recommend noting your model’s exact name from the underside of the robot. If you are unsure, our vacuum parts and accessories guide can help you identify the right category.

Tangle-Free Design for Pet Hair

Pet hair and long human hair are the biggest enemies of robot vacuums. Look for arc-shaped asymmetric side brushes and rubberized main brushes that prevent hair from wrapping around the rollers. Both Lacvik kits feature anti-tangle technology, which minimizes maintenance and keeps suction consistent.

In our experience, the dual brush system on the Qrevo S5V kit is especially effective at guiding hair toward the dustbin inlet, reducing clogs. If you deal with heavy shedding, this design is a game changer.

Filter Quality and Dust Bag Capacity

A good brush replacement kit often includes filters and dust bags, which are equally important for air quality and suction. The Qrevo S Pro kit includes washable filters that capture up to 99% of particles, while the S5V kit features HEPA filters that block 99.9%. Larger dust bags, like the 3.3L version, mean fewer replacements.

Washable Mop Pads and Ease of Installation

Mop pads that can be washed and reused save money and reduce waste. Both Lacvik kits include microfiber mop cloths that are machine-washable and quick-drying. Additionally, every component snaps in and out without extra tools, so you can swap them in minutes.

We value kits that include a cleaning brush or screwdriver, as these small extras make maintenance simpler. The Qrevo S5V kit even includes a screwdriver for the side brush screws, which is a thoughtful touch.

Final Thoughts

After comparing both Lacvik kits, we recommend the Qrevo S Pro/QV 35A Replacement Accessories for owners of those models who want a complete set with washable filters and a 3.2L dust bag. For those with a Qrevo S5V or Curv, the Qrevo S5V Replacement Parts for Roborock Qrevo S5V offers a superior tangle-free dual brush and HEPA filtration, making it ideal for pet households. Both kits deliver excellent value and restore your robot’s cleaning power without breaking the bank.
