Abstract: A vacuum cleaner with an automated diverter valve is described. The vacuum includes a handle, body, base, an automated diverter valve and air duct including two input ports. An automated diverter valve assembly at the junction of the dirty air intake within the base extends the air duct within the base and connects to the main air duct of the vacuum to the beater bar input and an attachment input. The automated diverter valve causes the air intake of the vacuum to be drawn from either the beater bar (floor) air input or the attachment input depending upon the position of the vacuum handle.

Abstract: A vacuum cleaner with a cooled drive belt is described. The vacuum has a handle, body, base housing, cooling fan, motor, drive belt and a drive belt housing. A fan draws ambient air over a drive belt within the belt housing. The belt housing can have a main belt housing and a belt housing cover. The belt housing can contain an air intake and air exhaust connected by an air duct. Belt housing can have a filter in order to clean intake air. The result is a vacuum with significantly greater longevity—reducing costs and increasing reliability of the vacuum for the user.

Abstract: An air cleaner including touch points is provided according to an embodiment of the invention. The air cleaner includes a chassis and one or more visually coded touch points on the chassis. The one or more visually coded touch points include indicia of user-contactable components of the air cleaner.

Abstract: An air cleaner is provided according to an embodiment of the invention. The air cleaner includes a high voltage power supply configured to provide a high voltage to a collector cell and a shut-down circuit coupled to the high voltage power supply. The shut-down circuit is configured to monitor an electrical current supplied to the collector cell, remove electrical power to the collector cell if the electrical current exceeds a predetermined cell current threshold for a predetermined time period, and generate an indication if the electrical power is removed from the collector cell.

Abstract: A magnetic clutch is provided according to an embodiment of the invention. The magnetic clutch includes a shaft including a flange, a magnetic clutch hub installed on the shaft, with the magnetic clutch hub being magnetically responsive, and an actuator member that magnetically operates on the magnetic clutch hub and causes the magnetic clutch hub to frictionally contact the flange of the shaft. The contact transfers rotational power between the magnetic clutch hub and the shaft.

Abstract: A tower ionizer air cleaner is provided. The tower ionizer air cleaner includes a tower chassis, with a base of the tower chassis including a small footprint, one or more airflow inlet openings in the tower chassis, one or more airflow outlet openings in the tower chassis and substantially opposite to the one or more airflow inlet openings, and an ionizer element positioned within the tower chassis. The tower ionizer air cleaner further includes one or more fan units substantially vertically located within the tower ionizer air cleaner and affixed to the tower chassis. The one or more fan units are configured to provide an airflow between the one or more airflow inlet openings and the one or more airflow outlet openings and through the ionizer element.

Abstract: An air cleaner is provided according to an embodiment of the invention. The air cleaner includes a power supply, an electrostatic precipitator cell, and a door. The door closes the electrostatic precipitator cell inside the air cleaner. The air cleaner further includes a door switch that is actuated by the door when the door is substantially closed. The air cleaner further includes a cell presence switch. The electrostatic precipitator cell actuates the cell presence switch when the electrostatic precipitator cell is at least partially inserted into the air cleaner. The cell presence switch and the door switch enable electrical power to be supplied from the power source to one or more air cleaner components when the electrostatic precipitator cell is at least partially inserted into the air cleaner and when the door is substantially closed.

Abstract: An air cleaner is provided according to the invention. The air cleaner includes a main power source, a backup power source, a state detector configured to detect a state of an air cleaner component, and a state memory element coupled to the state detector. The state memory element is configured to transfer a current state in the state memory element to a control circuit: using main electrical power from a main power source, receive the state in the state memory element from the state detector when the state memory element is receiving backup electrical power from a backup power source, and store the state in the state memory element using the backup electrical power.
