Abstract
A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.
Claims17
A cleaning apparatus, comprising:
- a housing for movement over a surface to be cleaned;
- a suction source provided with the housing, the suction source including a motor and the suction source adapted to generate a working airflow through the housing;
- an electrical circuit supplying power to the motor;
- and
- a motor protection system provided with the housing, the motor protection system comprising a switch electrically coupled within the electrical circuit and a pre-motor filter, the motor protection system adapted to detect moisture in the working airflow and wherein the switch is normally closed and is selectively openable by the pre-motor filter and adapted to control operation of the motor based thereon.
