The present disclosure relates to a cleaner according to one embodiment, which includes a cleaner body, a grip member disposed on the cleaner body to be gripped by a user, a pressure sensor part disposed in the grip member to detect pressure applied by the user to a part of an outer surface of the grip member, a driving unit disposed at a lower portion of the cleaner body to move the cleaner body, and a controller to control the driving unit based on the detected pressure.

A method for charging an energy storage device for use in a cleaning appliance includes the following steps: reading an energy demand signal representative of an energy required by the cleaning appliance for a predetermined cleaning run; and outputting a charging signal using the energy demand signal, the charging signal causing the energy storage device to be charged as a function of the energy required.

A vacuum system for use in excavation operations. The system uses a tank having an open end that is closed by a door. The door is opened and closed by a door lifting assembly made up of an upper linkage arm, a lower linkage arm and a hydraulic cylinder. A socket is formed in the upper linkage arm, and a shaft housing is formed in the lower linkage arm. The shaft housing engages with the socket to latch the door closed. The upper linkage arm is attached to the door at a first pivot axis and is attached to the lower linkage arm at a second pivot axis. The lower linkage arm is attached to a side of the tank at a third pivot axis. When the door is open, the second pivot axis extends below a reference plane that contains the first and third pivot axis.

An apparatus and method for monitoring the productivity of a portable machine are provided. The method includes receiving motion data for at least one component of the portable machine from a multi-axis accelerometer, receiving position data for the at least one component from a process parameter sensor communicatively coupled to the at least one component, and determining, based on the received motion data and the received position data that the at least one component is oriented in a predetermined position for productive operation. The method also includes determining an area of productive operation using at least one physical dimension of the at least one component and the received motion data when the at least one component is oriented in the predetermined position for productive operation and incrementing a total area counter based on the determination.

An apparatus for sealing a vacuum tank door. The apparatus comprises a circular flange attached to a door panel of a vacuum tank, a horizontal crossbar connected to the center of the door panel and a lifting assembly. The lifting assembly comprises an upper linkage arm, a lower linkage arm, and a hydraulic cylinder. Activation of the hydraulic cylinder causes the linkage assembly to move downwards pulling on the horizontal crossbar and pulling the vacuum tank door towards the tank. Activation of the hydraulic cylinder also causes a connection point of the lower linkage arm and the upper linkage arm to move over-center of the connection between the lower linkage arm to the to the tank creating a tight seal between the vacuum tank door and the tank.

A cleaner holder includes: a first body having a first charging port configured to charge a cleaner; a second body protruding from the first body to support the cleaner; and a battery accommodating space recessed in one surface of the second body and configured to accommodate a battery detachably mounted to the cleaner, wherein a second charging port configured to charge the battery is provided in the second body.

An upright vacuum cleaner (1) includes a brushroll (11); a motor assembly (200) including a motor housing (21) and a motor (22), in which a rotating axis of the motor (22) and a rotating axis of the brushroll (11) are disposed in a non-parallel manner, and the motor (22) drives the brushroll (11) rolling by a drive belt (13) and is rotatable between a first upright position of tensioning the drive belt (13) and a first oblique position of loosening the drive belt (13); a body assembly (300) including a body (31), a bridging member (32) and a dirt cup (37) mounted on the body (31), in which the bridging member (32) is rotatably connected with the motor housing (21) to make the body (31) rotatable between a second upright position and a second oblique position, and the motor (22) is moved by the bridging member (32) from the first oblique position to the first upright position when the body (31) moves from the second upright position to the second oblique position.

A vertical vacuum cleaner (1) is provided, including a brushroll (22); a motor assembly (200) including a motor housing (21) and a motor (22), in which the motor (22) is configured to drive the brushroll (22) to roll via a drive belt (13) and is rotatable between a first upright position where the drive belt (13) is tensioned and a first oblique position where the drive belt (13) is loosened; a body assembly (300) including a body (31) and a bridging member (32) rotatably connected with the motor housing (21); a lever driving device rotatably disposed to the motor housing (21) and having two ends respectively fitted with the bridging member (32) and the motor (22), in which the bridging member (32) is configured to drive the motor (22) to move from the first oblique position to the first upright position via the lever driving device.

A vacuum cleaning system includes an upright vacuum cleaner operable in a cordless mode and a corded mode. The upright vacuum cleaner includes a cleaning head for removing debris from a floor, a debris tube connected to the cleaning head for receiving the debris, and an electrical connection interface. The vacuum cleaning system also includes a battery and a power cord adapted for connection to the electrical connection interface. The upright vacuum cleaner operates in the cordless mode when the battery is connected to the electrical connection interface. The vacuum cleaner operates in the corded mode when the power cord is connected to the electrical connection interface.
