A surface cleaning machine including at least one cleaning roller, a drive device for rotary driving of the at least one cleaning roller, a wetting device for applying cleaning liquid to the at least one cleaning roller, and a suction unit arrangement for generating a suction stream is provided. The suction unit arrangement is fluidically connected to at least one suction duct and at least one suction nozzle that is associated with the at least one cleaning roller. The wetting device includes at least one pressure-controlled switch that opens a fluid path for cleaning liquid to the at least one cleaning roller and shuts off the fluid path, and the at least one pressure-controlled switch is coupled to the at least one suction duct, wherein a suction stream in the at least one suction duct moves the pressure-controlled switch into the open position and/or maintains the open position.

While the described wand can include any suitable component, in some cases, it includes a wand head having a vacuum port with a front face and a back face, a jet port that is coupled at the back face of the vacuum port, and a jet that is coupled to the jet port, the jet being configured to spray effluent through the vacuum port to a surface to be cleaned. In some cases, the front face includes a first jog that extends from a front side of the front face and across a width of the front face. In some cases, the second face includes a second jog that extends across a width of the back face of the vacuum port such that the second jog extends into the vacuum port and defines a second recess at a back side of the back face. Additional implementations are also described herein.

A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air including dust flows and at least a portion of which extends in a front and rear direction. First and second rotation cleaning units are arranged on the lower side of the nozzle housing to be spaced apart from each other in a lateral direction. Each of the first and second rotation cleaning units includes a rotation plate adapted for attachment of a mop. A first driving device including a first driving motor drives the first rotation cleaning unit and a second driving device including a second driving motor drives the second rotation cleaning unit. A water tank mounted on the nozzle stores water to be supplied to the mop.

A cleaner includes a body forming an external appearance, and a spin-mop cleaning module configured to support the body and including at least one spin-mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side. The inclination angle of a lower surface of the spin mop is changeable relative to a horizontal plane.

A cleaner includes a body which forms an outer appearance; a mop module having at least one rag part which is provided to wipe a floor while rotating; and a detaching module comprising at least one catching portion which detachably catches the mop module to the body, and a manipulation button which is exposed outside, wherein when the manipulation portion is touched, the catching portion releases catching of the mop module.

A mobile floor cleaning robot includes a body defining a forward drive direction, a drive system, a cleaning system, and a controller. The cleaning system includes a pad holder, a reservoir, a sprayer, and a cleaning system. The pad holder has a bottom surface for receiving a cleaning pad. The reservoir holds a volume of fluid, and the sprayer sprays the fluid forward the pad holder. The controller is in communication with the drive and cleaning systems. The controller executes a cleaning routine that includes driving in the forward direction a first distance to a first location, then driving in a reverse drive direction a second distance to a second location. From the second location, the robot sprays fluid in the forward drive direction but rearward the first location. The robot then drives in alternating forward and reverse drive directions while smearing the cleaning pad along the floor surface.

Systems and methods for providing a wand that is configured to clean a surface, such as carpeting and rugs, are disclosed herein. While the described wand can comprise any suitable component that allows it to be used to clean a surface, in some cases, the wand includes a wand head having a shroud, with a jet orifice and a vacuum port being disposed within the shroud. In some such cases, the vacuum port includes a breaker bar that is recessed within the shroud such that a portion of the shroud extends past the breaker bar. Additionally, in some cases, the shroud further includes one or more rollers that are optionally adjustable in height such that the wand head can is useable by operators of varying heights. In some cases, the wand head is coupled to a vacuum tube that attaches to a vacuum. Additional implementations are also described herein.

The present disclosure provides a floor cleaner that includes a replaceable component, such as a brushroll or a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

A cleaner includes a nozzle assembly, a cleaner body in communication with the nozzle assembly, and a damp cloth-based wiping unit coupled to the nozzle assembly. The damp cloth-based wiping unit includes a water tank. The water tank includes a storage space defined therein for storing water, an air hole defined in a top face of the water tank for receiving external air, a discharging port formed on a bottom face of the water tank for discharging the water from the storage space, and a deformable member configured to be depressed inwardly into the storage space. A damp cloth is attached to a bottom face of the water tank for receiving the water discharged through the discharging port. A pressing mechanism is configured to selectively press and translate the deformable member.

A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air including dust flows and at least a portion of which extends in a front and rear direction. First and second rotation cleaning units are arranged on the lower side of the nozzle housing to be spaced apart from each other in a lateral direction. Each of the first and second rotation cleaning units includes a rotation plate adapted for attachment of a mop. A first driving device including a first driving motor drives the first rotation cleaning unit and a second driving device including a second driving motor drives the second rotation cleaning unit. A water tank mounted on the nozzle stores water to be supplied to the mop.
