Abstract: A method of using an upright vacuum cleaner includes positioning a floor nozzle on a surface to be cleaned, measuring a first characteristic of a brushroll motor with a first sensor, and communicating the first characteristic with a controller. The method also includes comparing the first characteristic with a first threshold value stored by the controller, which is associated with determining if the floor nozzle is on a first cleaning surface or a second cleaning surface. The method further includes changing a suction motor between a first mode when feedback received by the first sensor is greater than the first threshold value, and a second mode when feedback received by the first sensor is less than the first threshold value. The method also includes operating the suction motor at a first speed while in the first mode, and at a second speed while in the second mode.

Abstract: A cleaning system including a motor, an impeller driven by the motor, a battery receptacle, and a motor controller. The battery receptacle is configured to receive a battery pack. The battery pack includes one or more battery cells and a battery controller. The motor controller is configured to receive from the battery controller one of a first type of data and a second type of data, and operate the motor at a defined speed, the defined speed being a first speed upon receiving the first type of data, and a second speed upon receiving the second type of data.

Abstract: A cleaning system including a motor, a battery receptacle, and a motor controller. The battery receptacle is configured to receive a battery pack. The battery pack includes one or more battery cells and a battery controller. The motor controller is configured to receive from the battery controller at least one selected from the group consisting of a first signal indicative of a first characteristic of the battery pack and a second signal indicative of a second characteristic of the battery pack. The motor controller is further configured to operate the motor at a defined speed, the defined speed being a first speed upon receiving the first signal and a second speed upon receiving the second signal. Wherein the first characteristic and the second characteristic are at least one selected from the group consisting of a capacity, a current, and a resistance.

Abstract: A vacuum cleaner includes a base having a floor nozzle that defines a suction chamber, a brushroll driven by a brushroll motor, and a brushroll motor sensor configured to measure an electrical current used by the brushroll motor. The vacuum cleaner further includes a pressure sensor configured to measure an internal pressure within the vacuum cleaner, and a controller in communication with the brushroll motor sensor and the pressure sensor. The controller is operable to control an operating speed of the brushroll motor based on feedback received from the pressure sensor and the brushroll motor sensor.
