ABSTRACT:
A vacuum cleaning device powered by compressed air includes a canister forming an internal collection chamber for collecting liquid and debris sucked up by the vacuum cleaning device. The vacuum includes a user operated drain from which liquid and debris collected in the collection chamber of the vacuum can be drained, when desired, and may also include a liquid extraction conduit extending into the collection chamber and attachable to a liquid pump for pumping liquid sucked up into the vacuum from the collection chamber. This makes draining the collection chamber much easier that in other vacuums. The vacuum device also includes a filter for air leaving the device which may include filter material in a filter housing over which a vacuum bag may be placed. A bypass in the filter housing may be opened to allow air from the device to bypass the filter material in the housing and pass directly into the vacuum bag.
