ATTACHMENT is for cleaning bare floors with a Dyson Ball Upright Vacuum (purple). This part has never been used as I ended up with 2 of the same kind of heads after buying an "extra parts package" from Dyson. The attachment is 11 3/4 inches or 295 mm wide. We live in a condo in James Bay which has a circular driveway in front so you can park off the street if you would like to have a look at the part. I will meet you just outside the front door and will be wearing a mask. Feel free to call, email or text. Thank you for your interest.
