Equipment Maintenance/Cleaning

No matter how different our listening tastes may be we all are faced with keeping our audio gear clean and I'm sure some take this to higher levels of scrutiny than others. I would like to know who may be using a hand held vacuum device that works particularly well when its time to get in to delicate crevices and/or around the back side of your rack/equipment storage. There are many good commercial units available but they always seem to do well in some areas and compromise in others. An example of this and reason for my inquiry is my Dyson unit. Its great for carpet and hard wood floors but the hand held device isn't great mainly because the hose is too short and stiff. At any rate let me know if you are using a product that has worked well for you in cleaning your audio electronics.  Thanks in advance.
