Sorry for the late reply. The 1-1/2 hp is 110 the 2 hp is 220. I use mine on a band saw, drill press, little lunch box planer and for the lathe all one at a time and it works pretty good.
Setting up the lid on the can, it has a lift mechanism, is a little fidgety but you only have to do it once. The directions are just a little challenging. Not useless just a little off, so just use some common sense. FYI the blower assembly comes all put together with the motor and is kind of heavy so get an extra hand to help set it on top
I like mine, I bought it pre buy and it works pretty darn good, it rolls around good, overall very pleased with it
