Dreame Side Brush for X40 Ultra Robot Vacuum Cleaner, Genuine 2pkt Dreame Side Brush for X40 Ultra Robot Vacuum Cleaner, Genuine 2pkt Original Dreame spare part, OEM: RSB14 The side brush for Dreame X40 Ultra / X40 Ultra Complete is designed to maximize the performance of your vacuum cleaner, providing a deep and thorough cleaning of any surface. Thanks to its design and high-quality materials, the brush ideally picks up all dirt, dust and hair from hard-to-reach areas such as corners and edges. If the side brushes on your robot vacuum cleaner are worn, you might notice several issues: Reduced Cleaning Efficiency: Worn side brushes may not sweep debris effectively, especially along edges and corners. This can result in less thorough cleaning in those areas. Increased Debris Accumulation: With less effective brushing, dirt and dust may accumulate along baseboards and in corners, as the vacuum might not pick up everything as thoroughly. Potential for Scratches or Damage: If the brushes are damaged or broken, they might scratch or damage floors or other surfaces over time. Strain on the Vacuum: Worn brushes might put extra strain on the vacuum's motor or other components, potentially leading to reduced performance or damage. It's a good idea to replace side brushes regularly to maintain optimal cleaning performance and avoid potential issues. Suitable For: Dreame X40 Ultra Robot Vacuum and Mop with Auto-Empty and Mop Self-Cleaning Station
