Made of high-quality materials, this replacement kit includes side brushes that allow your vacuum cleaner to reach into corners for a more thorough cleaning. The filter captures fine dust to reduce dust, pollen, and other particles from entering the air you breathe. Uniquely designed brushes with rubber treads adapt to different floor surfaces, effectively removing debris from small dust to larger deposits. For optimal performance, it is recommended to replace the parts every 2 to 3 months as part of regular maintenance.
