I have recently seen that Makita have a 18V Vacuum pump which i was thinking would be handy for on top of roof's or just where theres no power supply by the units.

Was just wondering if anyone has had/used one and if they are worth it or not?

I've attached a link to the one i was reading and looking at there may be others/better ones this was just one i saw the other day.
