A vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator, and an illumination system. The agitator is rotatably disposed at least partially within the agitation chamber and includes an agitator body defining an illumination chamber. The illumination system is at least partially disposed within the illumination chamber and includes at least one light source. Alternatively, a vacuum cleaner includes a vacuum body defining an agitation chamber, an agitator rotatably disposed at least partially within the agitation chamber, an illumination coupled to the vacuum body and including at least one light source, and a light guide configured to redirect light emitted in a first direction from the at least one light source to a second direction.

Disclosed is a method of controlling a plurality of robot cleaners, the method including a first step of docking a first robot cleaner and a second robot cleaner with a first docking device and a second docking device, respectively, a second step of checking whether the first robot cleaner is undocked from the first docking device, and a third step of if the first robot cleaner docked with the first docking device again, undocking the second robot cleaner from the second docking device.

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.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head and the suction motor is powered by an energy storage member.

The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head and the suction motor is powered by an energy storage member.

A surface cleaning apparatus, wherein the suction motor is operable using current supplied from an energy storage member when the power cord is removed and operable using current supplied from an external source when the power cord is in electrical communication with the suction motor.

A cleaner includes a first extension pipe connected to a suction portion contacting a surface to be cleaned, and a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe. The first and second extension pipes operate in a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other. Such configuration enables a user to increase cleaning efficiency.

A vacuum accessory tool is provided. The vacuum accessory tool includes a body, a turbine, a generator, and a light source. The body defines a suction inlet, a fluid outlet, and a fluid flow path extending from the suction inlet to the fluid outlet. The turbine is rotatably mounted to the body in fluid communication with the fluid flow path to be rotated by fluid passing through the fluid flow path. The generator is coupled to the turbine such that rotation of the turbine rotates the shaft to generate power. The light source is electrically coupled to the generator and configured to receive the power generated by the generator to power the light source by the fluid passing through the fluid flow path.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner and an energy storage member may be in an upper end of the handle.

A surface cleaning apparatus includes a floor cleaning unit and a portable surface cleaning unit. The floor cleaning unit includes a surface cleaning head and an upper section moveably mounted to the surface cleaning head between an upright storage position and a rearwardly inclined floor cleaning position. The portable surface cleaning unit is connectable to the floor cleaning unit, and includes a portable surface cleaning unit air inlet connectable in air flow communication with the floor cleaning unit, a main body, an air treatment member, a suction motor, a handle and a capacitor. A remote charger is provided wherein the capacitor is rechargeable at a rate of at least 4 C.
