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.

Abstract: Disclosed herein are coated substrates comprising a coating layer and an adhesive formed on at least a portion of the coating layer. The coating layer may be deposited from a powder coating composition and comprises a dielectric strength of at least 50 kV/mm measured according to ASTM D149-09 (voltage limit 12.0 kV DC, Imax Limit 0.1 mA, 19 sec ramp, 20 sec dwell, 2 sec fall) and a thermal conductivity of at least 0.3 W/K·m measured according to ASTM D5470 (steady-state methods). The adhesive may be formed from an adhesive composition and comprises a thermal conductivity of at least 1.0 W/K·m measured according to ASTM D5470. Also disclosed herein are systems for coating substrates. Also disclosed are methods of coating a substrate.
