The tiles on site were cleaned cleanest, the suction of the handle also.
Whether dry or with wet suction - is to achieve a usable vacuum, at the least attractive force itself vertically to the wall disengages the handle, and immediately after installation.
At least my copy is completely useless.
Unfortunately, due to circumstances occurred in a nursing case only one and a half months after the use of the handle, so that I can forget a products back.
