The Dyson Motor Main Body is designed for V7 Motorhead models (SV11) and includes a dead battery. This electric cordless motor is compatible with Dyson V7 models and is made of plastic material. It features a lightweight design, click lock mechanism, low noise level, and easy cleaning. The item dimensions are 4 inches in depth, 6 inches in height, and 5 inches in width. This was our original vacuum and the battery is going bad, so instead of a new battery, were getting a different brand name altogether. Everything works as it should (other than the battery). It does work for a couple minutes when fully charged, but nothing like it should. Reasonable offers encouraged. We love bundle deals and combine shipping. Your purchase supports a very small family business....Thank You! Happy Shopping.
