Abstract: A surface treatment apparatus may include a surface cleaning head having an agitator, an agitator motor configured to cause the agitator to rotate, and a controller. The controller can be configured to determine a surface type corresponding to a surface to be cleaned and to transition the surface treatment apparatus between a first operational mode and a second operational mode based, at least in part, on the determined surface type. Determining the surface type may include measuring a plurality values corresponding to a current draw of the agitator motor over a predetermined time window at a predetermined time interval, determining an average corresponding to the measured values, comparing the average to at least a first threshold, and transitioning the surface treatment apparatus between the operational modes based, at least in part, on the comparison.

Abstract: In general, the present disclosure is directed to nozzle control circuitry for use in surface cleaning devices that preferably reduces overall power consumption of a surface cleaning device by detecting the start of a cleaning operation by a user before energizing one or more components such as an agitator. The nozzle control circuitry can detect a cleaning operation based on data output from one or more sensors (also referred to herein as operation sensors). For example, the nozzle control circuitry can communicate with at least one of a motion sensor such as an accelerometer, an orientation sensor such as gyroscope, and/or an air pressure sensor operatively coupled within a dirty air inlet to detect the presence of generated suction.

Abstract: A cleaning device includes a cleaning device body and a replacement head. The cleaning device body includes an elongated handle, a housing and a replacement head mounting section. The replacement head has a pad that is intended to clean a surface, such as a floor and is removably attachable to the cleaning device body. The housing includes a circuit board having at least one sensor capable of sensing motion. The handle includes at least one button that can turn on/off either a vacuum source or a jet nozzle that sprays cleaner fluid. The cleaning device body further includes at least one light mounted thereon. The at least one light is illuminated when the button is pressed and then the at least one light remains illuminated until a predetermined amount of time has passed during which neither the button has not been pressed nor motion sensed by the sensor.

Abstract: The present disclosure is generally directed to a GF detection circuit for use in blenders and other appliances that can detect current leak/GF events and selectively decouple/de-energize components of the blender that could bring a user in contact with dangerous electrical currents. Preferably, a blender consistent with the present disclosure includes at least one ground plane, e.g., in the form of conductive material/sections, disposed on the blender and/or blender jar that act as an input to a GF detection circuit that is at least partially implemented within the base of the blender.
