Choosing the right robot vacuum often comes down to its core cleaning component: the brush roll. Roborock’s recent lineup favors rubberized, anti-tangle main brushes that make pet-hair households easier to maintain.

Below is a concise, comparative summary of four common Roborock Roller Brush Comparison, their pros & cons, and the robot models they pair with.

Roborock Roller Brush Comparison

1. Roborock S8 Series Brush Roll

Design & Material: Features the DuoRoller system—These are two side-by-side rubber rollers, easy to clean and more friendly to hair entanglement.
Pros: Superior cleaning efficiency on all surfaces, easy to clean with removable ends. High-strength rubber material is durable and suitable for a variety of models.
Cons: Can still require maintenance for long hair.
Compatibility: Roborock S8, S8+, S8 Pro Ultra. Also compatible with Q5 Pro, Q8 Max, and similar models.

2. Roborock Qrevo Curv Brush Roll

Design & Material: Utilizes the DuoDivide™ system: two short, parallel brushes with a gap in the middle. Made from nylon bristles for deep carpet cleaning and silicone flaps for fine dust.
Pros: Arguably the best zero-tangle performance; effectively guides hair to the dustbin without wrapping. Modular design for easy disassembly and cleaning.
Cons: Can sometimes scatter debris before picking it up on hard floors.
Compatibility: Roborock Qrevo Curv, Qrevo CurvX, and other Qrevo series models (sold as P20 Pro in some regions).

2. Roborock Saros Z70 Brush Roll

Design & Material: A single roller incorporating a unique active cutting technology and metal slots to automatically cut and capture hair. Made from a combination of rubber fins and reinforced nylon bristles.
Pros: Exceptional at handling long human and pet hair, reducing tangles significantly. Excellent on hard floors. Detachable design allows for easy removal of tangles; material combinations (e.g., rubber and metal grooves) reduce daily tangles and allow for less frequent maintenance.
Cons: Narrow design can leave debris on carpet edges; long hair can still require manual removal over time.
Compatibility: Specifically designed for the Roborock Saros Z70 and the Roborock G30 Space Explorer edition.

4. Roborock Q10 Series Brush Roll

Design & Material: Integrated rubber+bristle single roller with JawScrapers comb system.
Pros: Fantastic anti-tangle performance for a budget model. Easy to maintain and gentle on hard floors.
Cons: The brush is less efficient when dealing with mixed floors. Despite the anti-tangle system, long hair or large amounts of pet hair may still be wrapped around the ends.
Compatibility: Roborock Q10 S5, Q10 X5, Q10 VF, and their "+" variants.
