Technical Examples

A vacuum cleaner powered by compressed air includes a canister forming an internal collection chamber. The vacuum cleaner includes a drain at the bottom of the collection chamber from which liquid and debris can be drained, and may also provide for pressurizing the collection chamber for forcing collected liquid from the drain to a liquid drain or collecting drum or tank. This makes draining the collection chamber easier than in other vacuum cleaners. Preferably the bottom of the chamber slopes toward the drain. The chamber may be pressurized by the compressed air used to power the vacuum cleaner. The vacuum cleaner may also include a separate pressure tank for holding a degreaser, detergent, or soap which can be sprayed onto the residue of a liquid spill afier the liquid has been sucked up. The vacuum cleaner may includes wheels and a handle for easy movement.
