  • System and method for detecting walls or objects within a specific proximity of a vacuum floor nozzle
    Patent number: 12605025
    Abstract: A vacuum cleaner may include a suction motor; one or more edge detect sensors; a headlight assembly; one or more light sensors; and a controller. The controller is configured to: determine whether the vacuum cleaner is within a predetermined distance of a vertical surface based on an input received from the one or more edge detect sensors; responsive to determining that the vacuum cleaner is within the predetermined distance of the vertical surface, increase a suction power of the suction motor to a predetermined value; determine an ambient light level in an environment of the vacuum; and adjust an intensity of the headlight assembly based on the ambient light level in the environment.
