Specially designed with soft suede to clean floor debris cleanly and gently to suit different floor surfaces. This removes everything from small dust to large deposits and better protects your floors. This filter traps fine dust, preventing dust, pollen and other allergens from entering the air you breathe. The filter and rotating brush can be cleaned under running water and must be completely dry before reinstalling. It can be easily removed and replaced as part of normal maintenance.
