The present invention relates to a gas driven automatic moving steam circulation window wiping robot, comprises a housing, a driving mechanism, a wiping mechanism and a steam circulation mechanism. The driving mechanism comprises a main drive shaft, a follower shaft, a first motor, a rolling wheel, a suction cup walking device. The suction cup moving device comprises a crankshaft, a support pole, suction cups and a second motor. The wiping mechanism comprises a striped wiping cloth, a UV sterilization lamp and rotary brushes. The follower shaft is drivably connected to the rotary brush. The steam circulation mechanism comprises a negative pressure suction mouth, a negative pressure pump, a water precipitation tank, a filter tank and a steam generator connected in series through pipes. The structure is reasonable, having the advantages of simple, convenient to use, saves water, safe and reliable, and having a high level of automation, can effectively solve the problem of existing window wiping robots unable to clean the corners of windows.

A fall protection device includes a frame, a rotation unit, a safety belt, and a braking unit. The rotation unit is rotatably disposed in the frame; the safety belt is wound up on the rotation unit, and adapted to be pulled to drive a rotation of the rotation unit. The braking unit includes a braking plate, a braking block, and a stopper. The braking plate is connected to the rotation unit, rotates with the rotation unit coaxially. The braking block is pivotally connected to the braking plate, and includes a stopping part. The stopping part of the braking block can be spun out by a centrifugal force produced by a rotation of the braking plate, and abuts against the stopper to limit the rotation of the rotation unit. The braking block includes an abutted part. The stopper is disposed in a movement path of the abutted part.

A support device and associated method of use may be used for supporting a surface to be cleaned, such as a tilt-in window, and associated cleaning supplies. The support device may include at least one protective support feature or surface, such as a top cushion. The support device may also include at least one support feature for supplies, such as an attachment ring and/or a bag or other supply receptacle. The support device may include a plurality of legs, such as two front legs and two back legs, and the legs may be foldable or compressible for moving or storage of the support device. Pairings of legs may further include locking features or other support arms or similar features. The support device may be configured to support one or more elements of a tilt-in window when those elements are in an open configuration, enabling easier cleaning of the window.

An adjustable support, comprising a base, a first tubular member extending upwardly from the base, the first tubular member comprising a first friction lock, a second tubular member arranged in telescoping engagement with the first tubular member, the second tubular member comprising a second friction lock and, a non-abrasive transverse member pivotably arranged on the second tubular member, wherein the first friction lock telescopingly secures the second tubular member within the first tubular member and the second friction lock pivotably secures the transverse member to the second tubular member.
