摘要: A vacuum cleaner includes: a vacuum motor; one or more sensors configured to generate sensor signals associated with the vacuum cleaner; and a controller configured to: process the generated sensor signals using a surface type model defining a mapping between generated sensor signals and surface types to determine a type of surface on which the vacuum cleaner is being operated; control the power of the vacuum motor in dependence on the determined type of surface; and update the surface type model based on the generated sensor signals and/or the determined type of surface.

摘要: A vacuum cleaner including a cleaner head defining a suction chamber and having an agitator arranged to be rotated by an agitator motor, a dirt separator, a vacuum motor arranged to draw air into the suction chamber and then into the dirt separator, and a controller. The controller is configured to monitor the electrical load of the agitator motor, compare the magnitude of the electrical load to a threshold, and selectively adjust the electrical power delivered to the vacuum motor. The controller is configured either to increase the electrical power delivered to the vacuum motor to a predetermined upper power level if the electrical load is greater than the threshold, or to decrease the electrical power delivered to the vacuum motor to a predetermined lower power level if the electrical load is smaller than the threshold.
