The Cleaner Head Assy Dyson 966377-01 is a brush head/tool attachment designed specifically for Dyson upright vacuums. Made from durable plastic, this red clip is suitable for models such as Cinetic Big Ball, DC55, DC41 MK2, and DC40. This product is sold individually and is ideal for those looking to replace or upgrade their vacuum cleaner with compatible parts from the Dyson brand. I think the motor inside doesn't work anymore but the brush a bar looks to be in great condition and it includes that red clip thing that you need onto the actual device if someone knew how to replace the motor in this and then I'm sure it would work absolutely fine
