A scrubber includes: a drive assembly that includes a motor that rotates about a motor rotation axis extending in an up-down direction; a tool that faces a cleaning target and that is rotated by the motor; a guard portion that is disposed at least partially around the tool and that is to be attached to the drive assembly; and an adjustment mechanism configured to adjust a height of the guard portion with respect to the drive assembly according to an attachment position of the drive assembly with respect to the guard portion.

A scrubber includes: a drive assembly that includes a motor that rotates about a motor rotation axis extending in an up-and-down direction; a tool that faces a cleaning target and is rotated by the motor; a guard portion having at least a part disposed around the tool; and an attaching/detaching mechanism that includes a hook member and attaches and detaches the drive assembly and the guard portion to and from each other.

The invention relates to a cleaning machine, including a cleaning head, a holding rod device and a joint device by means of which the holding rod device is articulated to pivot on the cleaning head. Arranged on the holding rod device is a connection element that has a first region and a second region, wherein the second region is at a spacing from the first region in a transverse direction and the transverse direction is oriented transversely to a longitudinal axis of the holding rod device, wherein the connection element is connected by way of the second region to a joint of the joint device with which a pivot axis is associated, and wherein the connection element is connected by way of the first region to the holding rod device.

A floor machine with a segmented ring gear may include a motor operably connected to a planetary driver. The planetary driver may include two or more planet gears engaging a ring gear that at least partially surrounds the planetary driver. The motor may generate rotational motion of the planet gears about a first axis, and the ring gear may cause counterrotation of the planet gears about a second axis. The ring gear may be provided in the form of two or more ring gear segments configured to be detachably coupled together. Thus, in the event that the ring gear is damaged, worn, or malfunctioning, only the affected ring gear segments may be repaired or replaced as opposed to replacing the entire ring gear. In this way, the segmented ring gear may reduce manufacturing costs, repair cost, down time, and/or provide other benefits.

A suction protection device for an air duct arrangement between a liquid collection area and a negative pressure source of a cleaning device is disclosed. The suction protection device includes a sealing body, sealing the air duct arrangement when positioned in its closed position and releasing the air duct arrangement when positioned in its open position to suck air out of the liquid collection area. The suction protection device further includes a load actuator configured to generate a pulling load via which the sealing body may be forced into the closed position and/or the open position.

The present disclosure relates to a steam cleaner, comprising a housing, a liquid storage assembly, a liquid pumping assembly, an execution unit and a control assembly. The liquid storage assembly includes a water storage part and a liquid storage part. The first pump assembly of the liquid pumping assembly draws clean water to generate steam through the heating assembly, and the second pump assembly quantitatively draws cleaning liquid through the pressing handle and piston pump. The two are mixed and sprayed out the nozzle channel, achieving synergistic cleaning with steam and cleaning liquid, improving cleaning efficiency, and offering convenient and safe operation.

A control method for a cleaning device is provided. The device includes a machine body and a handle connected to its rear side, the handle is configured to be gripped in hand by a user, a floor brush is connected to a lower end of the machine body and is provided with a movable first squeegee and a rolling brush, and the first squeegee is provided at a front side of the rolling brush; the method includes: receiving a stop instruction of the cleaning device; if the first squeegee is located at a first position in contact with a to-be-cleaned surface, controlling the first squeegee to be lifted up to a second position, the first squeegee is not in contact with the to-be-cleaned surface; controlling the cleaning device to move in a direction away from the user, and stop moving when a moving distance reaches at least a first distance.

A bidirectional cleaning machine includes a cleaning mechanism and a handle. The cleaning mechanism includes a housing, a transmission shaft is mounted in the housing, a first gear is arranged on the transmission shaft, and one end of the transmission shaft is fixedly connected to an inner cleaning disk; the transmission shaft is sleeved with a transmission sleeve, and one end of the transmission sleeve is perpendicularly and fixedly connected to an outer cleaning ring; a base gear is fixedly arranged on the transmission sleeve, and a fixed gear is fixedly arranged in the housing; connecting shafts are perpendicularly arranged on the base gear, and each connecting shaft is sleeved with a second gear and a third gear; a power mechanism is arranged on the housing; clamping rings configured as circular structures are arranged a side face of the housing, teeth are distributed on inner sides of the clamping rings.

A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

A joint for floor cleaning machines, comprising: a first portion, a second portion which is articulated to the first portion, a third portion which is articulated to the second portion; the joint comprises: first stable inclination element for the stable inclination of the second portion with respect to the first portion, second stable inclination element for the stable inclination of the third portion with respect to the second portion, the first stable inclination element and the second stable inclination element being connected to a single lever and being operable by the single lever.
