High-quality and durable materials: This rubber brush, made of high-quality ABS material, is durable, flexible, and washable. It adapts perfectly to various surfaces and reliably removes dust, hair, and dirt. A special anti-tangle design prevents long hair from getting tangled in the brush, ensuring worry-free cleaning. Highly effective deep cleaning: Thanks to a multi-directional floating mechanism, the brush stays close to the ground – even on uneven surfaces. It effectively cleans hard floors, tiles, carpets, and laminate floors, easily removing deeply embedded dust and pet hair. The detachable and easy-to-clean design allows for quick maintenance. Simply twist the caps at both ends to remove hair or dirt. The brushes can be washed with water and reused – hygienic, environmentally friendly, and cost-effective. Easy installation and optimal performance: Thanks to the snap components, the main brush can be easily replaced without tools. For best cleaning results, it is recommended to replace the brush rollers every 3-4 months. This will maintain the robot's strong suction power and significantly extend its lifespan.
