Thank you for viewing. This is a third-party compatible floor felt (two sets of bottom felt) for Dyson's soft roller cleaner head. Bulk purchases are also available♪ Please let me know in the comments. Compatible models: dyson DC74 V6 V7 V8 V10 V11 Disassemble the head, remove the floor felt (bottom felt), clean the adhesive surface, and then attach & insert. A Phillips screwdriver and a T8 Torx screwdriver are required to disassemble the head. Recommended for those who are considering replacing the felt because it is worn out. Available for immediate purchase. You can find reference videos for the replacement procedure by searching on YouTube. Please refer to them. Bottom strip / Plush strip / Felt strip <Notes on attaching the felt> Adhesion will be weakened if there is glue, dirt, or oil. Please completely remove the glue, as well as thoroughly remove any dirt or oil from the adhesive surface, and press firmly after attaching. You can use a sticker remover to remove the glue (however, the use of solvents such as sticker removers is at your own risk). After attaching, leaving it unused for about a day will allow it to adhere more strongly. Since this will be sent by mail, it may take about a week to arrive if it falls on a weekend or holiday. Please be aware of this. This is a third-party product, so please refrain from purchasing if you are looking for something equivalent to the genuine product. #dyson
