Claim:
1. A cable actuated lift device, comprising: a cable having a predetermined length; a first end of the predetermined length of cable provided in force transmitting communication with a linear actuator; a second end of the predetermined length of cable provided in force transmitting communication with a surface cleaning device; the linear actuator comprising an extended and retracted position, and adapted to extend and retract the predetermined length of cable, wherein the extended position of the linear actuator corresponds to the surface cleaning device being provided in contact with a surface and the retracted position corresponds to the surface cleaning device being provided in a raised position with respect to the surface; the linear actuator provided in force-transmitting communication with a first pulley, wherein the first pulley comprises a substantially vertical axis of rotation, and wherein the first pulley is translatable in a horizontal plane based on a movement of the linear actuator; the predetermined length of cable extending in a first direction and a second direction, wherein the cable is provided in contact with the first pulley and a second pulley, wherein the second pulley is provided at a transition point between the first direction and the second direction; the second pulley being rotatable about a first substantially horizontal axis that is substantially perpendicular to the substantially vertical axis; the second pulley being pivotable about a second substantially horizontal axis; and wherein pivoting of the second pulley about the second substantially horizontal axis permits translation of the surface cleaning device at least when the surface cleaning device is provided in contact with the surface to be cleaned, and wherein the first pulley is displaceable relative to the second pulley when the linear actuator is operated.
