Close-to-ground and edge cleaning with no blind spots: featuring an elastic close-to-ground design, it adapts to different floor heights including wooden floors, tiles, and carpets. When rotating at high speed, it closely follows corners and furniture edges, actively sweeping dust and debris from gaps into the suction inlet, addressing the common issue of robotic vacuums missing dust in corners. Anti-tangle and knot-resistant, reducing manual cleaning: optimise the arrangement of brush bristles and brush shaft structure to minimise entanglement of hair, threads and pet fur, lowering the frequency of manual disassembly and cleaning, especially suitable for families with pets and people with long hair. Wear-resistant and hard to break: The brush rod is made of ABS eco-friendly plastic, bristles made of durable nylon, resistant to bending and aging, preventing the brush from breaking or bristles falling out during high-speed use, extending its lifespan. Easy to replace, plug and play: Brush shaft size and clip design match perfectly, no modification needed, just plug in and replace, very easy to install.
