The material is moderately wear-resistant, with the bristles and rubber chosen from durable materials. Under daily sweeping of sand and dust, wear is relatively slow, and the service life is relatively long. Improved anti-tangling design: Some main brushes use a low-tangle structure, which can reduce the amount of long hair and pet hair wrapping, making subsequent cleaning easier. Easy replacement operation: Fixed with clips or press-type ends, they can be removed and installed by hand, making the process of maintaining and replacing the main brush relatively convenient. Beneficial for carpet beating: When rotating at high speed, the bristles can lightly beat the carpet fibers, helping to dislodge deep-seated dust and improving carpet cleanliness.
