Definitions

• the invention relates to a window wiper, which is formed in a substantially T-shaped, comprising a wiper head and a wiper handle, wherein the wiper head is arranged relatively cranked to the wiper handle and wherein the wiper head and the wiper handle limit a Kröpfungswinkel.

• wiper handles Due to the flexible joint, which connects the wiper head and the wiper handle elastically yielding each other, the lower portion of windows can be easily cleaned even if a window sill is arranged under the window and / or the window wiper has a longer wiper handle. Under a longer wiper handle according to the invention are to be understood wiper handles from about 20 cm in length.
• the wiping head of the wiper head is, as far as possible, consistently assigned to the window during the entire removal process, in particular that the angle with which the removal lip is passed over the window, remains essentially constant.
• the offset angle can be increased to a maximum end bend angle, so that the then straighter shape of the window wiper makes it possible to wipe the window to its lower edge without the wiper handle touching the sill and without the angle between Abziehlippe and window adversely changed.
• crank angle refers to the angle between the main axis of the Abziehlippe and the main axis of the wiper handle.
• the offset angle is preferably infinitely variable from an initial crank angle to the maximum end bend angle against the spring force of the flexible joint.
• the handling of the window wiper invention is very simple.

• the initial crank angle preferably corresponds to the minimum
• the maximum final crank angle can be 120 ° to 175 ° and the

Characterized in that the suction nozzle is connected in flow-conducting manner with the storage space, the cleaning liquid located in the storage space is conveyed through the suction nozzle in the recovery tank and held there.
• the ratio of the length of the window wiper over everything in cm to the maximum end-of-turn angle in ° is preferably 0.2 to 0.4. Such a ratio has proven to be advantageous in practice. For example, if a window wiper for use having a length exceeding about 40 cm is used, the crank angle is approximately in the aforementioned range.
