This replacement roller brush set is designed for a wide range of Roborock robot vacuum models, including the QV 35A, QV 35S, Q7 series, S7 series, T7S series, Q Revo, Q Revo MaxV, and Q Revo S. Each pack contains two rubber roller brushes, constructed from durable silicone material that resists hair tangling and maintains consistent cleaning performance over time. The rubber composition provides a balance of flexibility and stiffness, allowing the brushes to effectively agitate debris from carpets and hard floors without scratching delicate surfaces. The brushes feature a ribbed edge design that helps channel dirt and dust into the vacuum’s suction path, improving overall pickup efficiency. Their smooth outer surface and anti-static properties minimize the accumulation of pet hair and fibers, reducing maintenance intervals. The built-in bearing caps ensure stable rotation and quiet operation during cleaning cycles. These brushes are precision-molded to match OEM specifications, guaranteeing a snug fit into the brush compartment of compatible robotic vacuums. Users can expect reliable debris pickup on tile, wood, laminate, and low-pile carpeting. The rubber material withstands daily use and retains its shape even after repeated contact with edges and obstacles. The affordable price point makes this two-pack a cost-effective maintenance solution, offering a lower per-unit cost compared to single replacements. Installation is straightforward, requiring no tools or adapters, and the brushes are compatible with both main brush assemblies and side brush mounting points. The product is intended for routine replacement every three to six months, depending on usage frequency and floor conditions. By swapping out worn brushes, owners can restore their robot vacuum’s cleaning capability without investing in a full accessory kit. The absence of bristles reduces noise levels during operation and eliminates the risk of frayed edges shedding fibers onto floors. Each brush is individually wrapped to maintain cleanliness until installation. These roller brushes are constructed from thermoplastic elastomer (TPE) and silicone, offering resilience against household chemicals and temperature variations. The thermoplastic elastomer provides low friction against the vacuum’s housing, preventing excessive wear to the mounting points. The rubber composition is non-abrasive, ensuring no scratches on polished surfaces or sealed wood floors.

This replacement set delivers consistent performance and extended service life for multiple Roborock models at a very affordable price.
