Abstract: A cleaning apparatus comprises a cleaner module provided with a module mounting portion, a wireless cleaning module removably mounted to the cleaner module, and a wired cleaning module provided with a canister, a connection hose connected from the canister to the cleaner, and a connector provided in the connection hose to be removably mounted to the cleaner module. A wired cleaning mode using the wired cleaning module and a wireless cleaning mode using the wireless cleaning module are selectively operated by mounting one of the connector of the wired cleaning module and the wireless cleaning module, to the module mounting portion.

Abstract: A vacuum cleaner is provided. The vacuum cleaner includes a motor configured to rotate at a speed of predetermined revolutions per minute (RPM) in a normal mode, a first switch configured to control a power on/off operation of the vacuum cleaner, a second switch configured to change an operation mode of the vacuum cleaner, a battery unit including a first processor configured to, based on the first switch being pressed, control a power of the vacuum cleaner to be turned on, and a second processor configured to, based on the power of the vacuum cleaner being turned on according to an operation of the first switch, control the vacuum cleaner to operate in the normal mode, and according to an operation of the second switch in the normal mode, control the vacuum cleaner to operate in a standby mode where power supplied to the motor is turned off.

Abstract: A vacuum cleaner includes a fan motor configured to generate suction, an input button configured to receive an input of a user, a first power supply circuit configured to convert alternating current (AC) power supplied from an external power source and output first direct current (DC) power, a second power supply circuit configured to store electric energy upon receiving the first DC power, and output second DC power based on the stored electric energy, a driver circuit configured to drive the fan motor upon receiving at least one of the first DC power and the second DC power, a first semiconductor switching circuit configured to control the first DC power supplied to the second power supply circuit, a second semiconductor switching circuit configured to control the first DC power and the second DC power that are supplied to the driver circuit, and a microprocessor configured to output a control signal for turning on or off the first semiconductor switching circuit and the second semiconductor switching circu
