A vacuum cleaner has an electric motor driving an air impeller for creating suction and a pump which draws liquid material through an inlet tube from the bottom of a tank and expels it from the tank. The vacuum cleaner also includes a non-water soluble collection bag that attaches to a tank inlet and is disposed within the tank. The collection bag filters large particulate material out of the material which is vacuumed into the tank. |
