    摘要： 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.

    摘要： A surface treatment device comprising:
    a body having a treatment head for treatment of a surface, and
    a handle by which a user can move the device over the surface,
    wherein the handle is connected to a rod rotatably held within a sleeve provided on the body of the device, the rod having a generally circular cross-sectional profile with a recessed portion providing an abutment surface adapted to abut a latching member so as to prevent rotation of the rod and of the handle in a first rotational direction when the latching member abuts the abutment surface,
    wherein the latching member is pivotably support on a pin and provides a trigger portion operable by a user, such that application of force to the trigger portion by the user causes rotation of the latching member about the pin, causing disengagement of the latching member from the recessed portion of the rod thereby enabling rotation of the rod and of the handle in the first rotational direction,
    and characterised in that the latching member is biased towards engagement with the recessed portion of the rod.
