ABSTRACT:
A device for removing liquid and small particulate matter from various surfaces is provided. The device includes a single compartmentalized enclosure supporting a rechargeable battery, a vacuum source and an airflow booster system for drying the surface. As liquid and particulate matter are vacuumed via a hose or other vacuum director, they are trapped in a removable reservoir container which may be detached from the device for emptying and cleaning. The exhaust air produced from the resident vacuum system may be accelerated by a booster system which redirects accelerated airflow through a set of louvers toward the damp spot left by the removed liquid. The booster system may be used individually, without the aide of exhaust airflow from the vacuum, to also effect such drying of the surface. The device also has attached a signal system to alert passersby of the hazard created by the damp surface supporting the device in the preferred embodiment. All electronic functions of the device are adapted to be operated from a rechargeable battery power source which may be removed from the device for recharging or may be recharged in place via a recharging socket.
