  • Combination vacuum and air purifier system and method
    Patent number: 11471814
    Abstract: A system for environmental maintenance includes a vacuum unit, an air purifier unit, a controller communicatively connected to the vacuum unit and the air purifier unit, a sweep sensor communicatively connected to the controller, and a movement sensor communicatively connected to the controller. The sweep sensor detects debris swept into a detectable vicinity of the sweep sensor and the controller turns on the vacuum unit upon detection by the sweep sensor. The controller turns on the air purifier unit upon the vacuum unit being turned on, and the air purifier unit cycles on for a period as programmed in the controller. The movement sensor detects movement in detectable vicinity of the movement sensor and the controller turns on the air purifier unit upon detection by the sweep sensor, if the air purifier is not already turned on.

  • COMBINATION VACUUM AND AIR PURIFIER SYSTEM AND METHOD
    Publication number: 20200353402
    Abstract: A system for environmental maintenance includes a vacuum unit, an air purifier unit, a controller communicatively connected to the vacuum unit and the air purifier unit, a sweep sensor communicatively connected to the controller, and a movement sensor communicatively connected to the controller. The sweep sensor detects debris and sweeper in detectable vicinity of the sweep sensor and the controller turns on the vacuum unit upon detection by the sweep sensor. The controller turns on the air purifier unit upon the vacuum unit being turned on, and the air purifier unit cycles on for period as programmed in the controller. The movement sensor detects movement in detectable vicinity of the movement sensor and the controller turns on the air purifier unit upon detection by the sweep sensor, if the air purifier is not already turned on.
