Vacmaster VWM510 5-Gallon 5 Peak HP Remote Control Wall Mount Wet/Dry Shop Vacuum

The canister for this unit is very well constructed and very thick. I can see that drilling holes and bolting on some wheels would be easy. but, vac master does make a unit with wheels.

The suction hose goes to the canister not through the motor so I guess it does not cool the motor.

You can. Make absolutely sure there are no embers. I would put the vacuum outside. I would not want to put the ash dust in the air in the house if the fit on the filter is not perfect. The hose length should make that doable.

Yes. We have ours mounted on the wall and remove it from time to time to use elsewhere. Just press in one clip and lift it off the mounting bracket. Just make sure the cord is not wrapped thru the lip that goes onto the mounting bracket when hanging it back up.

You may be able to put 2 together. See what’s available at Home Depot

lol don't put a trash bag inside the vacuum. It's a vacuum... It'll try to suck the bag through the filter like everything else. The bag is air tight so no air flow. No air flow means no suction and a burnt out motor.

Not sure how much it blows. Never really used it for that But it surely does suck. I really like this machine. Very well made, wall mountable and well priced here. If you compare the price with the one available at Sears you will see it's virtually the same machine
