Cleaning apparatus

A cleaning apparatus, comprising:

• a cleaning base comprising a brush roll capable of contacting a surface to be cleaned, a cleaning fluid dispenser for dispensing cleaning fluid to the brush roll and/or the surface to be cleaned, a suction nozzle and a brush-roll motor for driving the brush roll in rotation;
• a manipulating shaft, a lower portion of which is rotatably coupled to the cleaning base, an upper portion of the manipulating shaft is provided with a first handle, the manipulating shaft including a first engagement portion provided with a first port in fluid communication with the suction nozzle, a second port in fluid communication with the cleaning solution dispenser, and a first electrical connection terminal in electrical communication with the brush-roll motor;
• a portable cleaner body removably installed on the manipulating shaft and including a supply tank for storing cleaning liquid, a recovery tank for storing dirty liquid, a suction motor in fluid connection with the recovery tank, a second handle for the user to carry the portable cleaner body, a battery pack, and a second engagement portion providing a third port in fluid communication with the recovery tank, a fourth port in fluid communication with the supply tank, and a second electrical connection terminal in electrical conduction with the battery pack;
• wherein the second engagement portion is configured to be capable of coupling with the first engagement portion to fluidly connect the third port to the first port, the fourth port to the second port, and the second electrical connection terminal to the first electrical connection terminal;
• and
• a suction extension hose set independently of the manipulating shaft and the portable cleaner body and having a first end portion and a second end portion positioned on opposite ends in the length direction, and the suction extension hose providing a first fluid pathway, a second fluid pathway, and an electrical circuit located between the first end portion and the second end portion;
• wherein the second end portion is constructed to be capable of coupling with the second engagement portion to electrically connect the first fluid pathway to the third port fluidly, the second fluid pathway to the fourth port fluidly, and the electrical circuit to the second electrical connection terminal;
• wherein the portable cleaner body includes a housing, the recovery tank and the supply tank are both removably mounted to the housing, the recovery tank is located directly below the suction motor;
• wherein the portable cleaner body also includes a pump for outputting cleaning fluid from the supply tank outwardly;
• wherein the first handle is provided with a first control component for user operation, the second handle is provided with a second control component for user operation, the first control component has a first control button and a second control button for controlling the operation of the suction motor and the pump when the portable cleaner body is supported on the manipulating shaft, and the second control component has a third control button for controlling the operation of the suction motor when the portable cleaner body is removed from the manipulating shaft;
• and
• wherein the suction extension hose has a fourth control button for controlling the operation of the pump when the second end portion is coupled with the second engagement portion.
