"Double Roller Soft Brush for Dyson V7 V8 V10 V11 V15 Material: ABS Product dimensions (LWH): 22.5×13×27cm Package dimensions (LWH): 29×24×9.5cm Weight: 900 g Features Two fluffy soft roller brush heads can easily capture large pieces of debris and remove fine dust. Since it has the rear brush, you can now vacuum on the back-pull, with the traditional brush-head you can only vacuum forward, and anything else kind of gets trapped on the rear bumper/felt strip, but this totally eliminates that. Being able to vacuum on the back pull has cut down your vacuuming time drastically, which is a huge plus. Easy to Disassemble and Install, Red button, one-click disassembly, easy to clean. Perfectly Compatible, Suitable for Dyson V7 V8 V10 V11 V15 vacuum cleaner. *Note: it is not for carpeted flooring. Package Include 1 x Double Roller Soft Brush"
