Aspects of the present invention relate to a triggerless extractor surface cleaning device for cleaning a surface in which a cleaning solution is distributed to the surface and extracted using suction along with dirt and/or debris on the surface in a continuous operation as the extractor moves along the surface. The extractor further comprises an encoder positioned adjacent a wheel of the extractor for detecting a rotational direction and speed of the wheel to generate a signal. Based on receiving the signal, a controller controls operation of a valve to situationally distribute the cleaning solution to the surface depending on a forward rotation of the wheel and independent of user actuation of a trigger positioned on a handle used to propel the extractor along the surface. Distribution of the cleaning solution can be further optimized based on the detected rotational speed of the wheel.

An autonomous cleaning robot (e.g., an autonomous vacuum) may clean an environment using a cleaning head that is self-actuated. The cleaning head includes an actuator assembly comprising an actuator configured to control rotation and vertical movement of a cleaning roller, a controller, and a cleaning roller having an elongated cylindrical length connected to the actuator assembly. The cleaning head also includes a computer processor connected to the actuator assembly and a non-transitory computer-readable storage medium that causes the computer processor to map the environment based on sensor data captured by the autonomous vacuum. The computer processor may determine an optimal height for the cleaning head based on the map and instruct the actuator assembly to adjust the height of the cleaning head.

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 floor cleaner including a recovery tank. The recovery tank includes a tank body having a lower end wall, an open upper end, and a sidewall that extend upwardly from the lower end wall. A cover that includes a suction air outlet in fluid communication with a vacuum source. An inlet duct extends upwardly from the lower end wall. The recover tank includes a shutoff float including a float body and a closure. The float body is configured to float on a surface of cleaning fluid and the closure is received in the suction air outlet to close the suction air outlet. The float body moves along the inlet duct as the float body floats on the surface of the cleaning fluid. The float body includes an aperture extending through the float body and the inlet duct extends through the aperture of the float body.

The multifunction machine for cleaning and sanitizing surfaces and environments that has a body-machine that includes: a waste suction device; a wet filtration and collection device of sucked waste; a steam generating and steam expulsion device towards said surfaces and environments; a primary circuit for circulating sucked air and waste having a first inlet and a first outlet obtained in the body machine; a secondary circulation circuit for air which has a second inlet and a second outlet obtained in the body machine which also includes an ionizing device placed on said secondary circuit.

An arrangement of components in a portable wet vacuum cleaner, wherein the wet vacuum cleaner includes a container for collecting a liquid-dirt mixture. The component arrangement is characterized, in particular, by a sloping sealing plane as the upper termination of a collecting container of the wet vacuum cleaner, wherein the sloping sealing plane includes a filter unit. In a second aspect, the invention furthermore relates to a wet vacuum cleaner having a component arrangement of this kind.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

The present disclosure relates to a battery powered floor cleaner (10). The floor cleaner (10) is operable in various modes based on the capacity of a battery pack (22), such as a normal power mode (40) and a low power mode (42).

An apparatus may include a first layer that includes a plurality of inlets and a surface feature; a second layer, where the surface feature opposes the second layer; an outlet, and a pattern defined on at least one of the first layer and the second layer, where the pattern defines a suction path from each inlet of the plurality of inlets to the outlet.
