You don't mention whether your vacs are round or oval, but why not use that bracket I listed in the other thread when we were on this subject. It holds a foam brush by the head. Turned around backwards, with the bolt holes facing out it should be great for a vac hose. For an oval you could bolt it on the side or on the back of an adjacent vac. I can't picture it being a huge deal to use on a round one or maybe bolt it to an adjacent light pole or something.
