ABSTRACT:
A manual operated and battery powered device is provided for complete removal of liquid spills by use of both vacuum and blow-drying. The device provides a wheeled cart including a liquid-tight pan on which are retained one or move waste liquid receivers. An electric motor powered blower within an enclosure provides both suction and blown air through attached flexible hoses. In operation, the blower creates a vacuum in the receiver which, through the flexible hoses, is used to suction waste material from a working surface. The waste material is captured in the receiver. The device is small to reduce interference with surrounding activities. The design enables cordless operation with convenient recharging from standard electrical power sources during non-operational periods.
