Material: The main brush cover is made from wear-resistant materials such as ABS plastic or polycarbonate to ensure durability and withstand repeated friction. Disassembly and cleaning: The design allows easy disassembly, simple cleaning and maintenance, and helps prevent dirt buildup that can impair suction. Sealing: A good seal design prevents dust and dirt from entering the machine, extending the life of the motor and other components. Fit: The main brush cover must be perfectly matched to the respective vacuum model to ensure secure installation and prevent loosening or detachment during operation. Use scenarios: - Daily cleaning on carpets and hard floors where consistent suction is important and routine maintenance is desired. - Homes with pets, where frequent fur contact requires a durable cover that maintains performance. - Seasonal or routine maintenance after brush replacements to ensure secure fit and uninterrupted operation.
