Designed for Tineco wet and dry vacuums. Compatible with: Tineco Floor One S7 Flashdry PET and Tineco Floor One S6 Flashdry PET. The kit includes 2 brush rollers and 2 HEPA filters. The intelligent self-cleaning brush roll offers maximum convenience. It can be effortlessly removed, cleaned, and replaced. The Tineco brush roll should be replaced every 3-6 months depending on the level of dirt. The high-performance microfiber roller head with soft bristles not only vacuums efficiently but also cleans the floor at the same time. The vacuum's bristles reliably capture small particles, large debris, and liquids. Additionally, the HEPA dry filter is perfectly suited to trap escaped particles during the cleaning process while simultaneously expelling allergen-free fresh air.
