My previous vacuum cleaner had a blow as well as suck option (Here's hoping Sh!tstirrer misses this post, else it'll be full of double entendres! ;D ). The blow function was great for helping get into hard to reach places to blow dust out from/off equipment. I've seen a hand-held device used by the local gym to help keep their equipment clean, but enquiries at local hardware stores have turned up a blank. Anyone know what the term if for them, or what I am talking about?
