We would never buy such a robot for simple apartment window. And the shower is anyway cleaned every day after use manually. But we have a conservatory with large windows (depending 3,9m x 0,9m) as roof. Since I can not clean these disks (you have to climb onto the roof), we found no one to whom we could delegate this task, no professional window cleaners. So it seemed to us the use of a robot to be exactly the solution to solve our cleaning problem.
Shipping: prompt and easily
First impression: compact device consists of two parts. Each 4 small micro fiber should clean the discs. Quiet doubt moved, but a robot can indeed do this work long enough (if the battery does not have to be constantly recharged).
So the first test on a sliding glass door. After the cliff was overcome with the calibration of the magnetic force, he let rip. After shutting down the window dimension he was working from the surface of the disc clean actually.
Result:
light streaks on the previously clean plate, but could easily take off. Noise pollution is considerable. Since on both sides of the disc sits a part of the device, both surfaces must be easily navigable. Very important: the control requires a minimum of 1 cm high edge in order to detect the end of the disc can.
Now on to our roof windows.
New calibration because the discs are slightly stronger. After inspection of the equipment must be recalibrated, because the pilot light glowed red. Either we did something wrong, or the device is working so strange. Each new placement required a new calibration of the magnetic force.
If the Windoro starts, he experiences himself as first the width of the window, then he goes up and turns and now moves endlessly from the upper edge, back and forth. With the remote control he was also stop and restart. Then he went down first, and then turn around and down again to the top, where he constantly drove again at the top of back and forth. A manual control reconnaissance of the surface is possible but expected of anyone.
Conclusion:
Not suitable for our men application. For normal window I would always prefer a manual cleaning. The advantages of operation with magnetic force against a window-cleaning robot that speaks to, have not opened up to me. With large windows that can not be opened, a person inside and outside is needed to both parties on the start button to connect signally respectively. An advantage might be that the preening part copes well on a wet plate, as long as the control part moves to the opposite side dry. Whether the wheels leave no trace after a certain period of use on the clean inside questionable, but I could not test.
We had to return the device. It must be remembered: Porto 20 for delivery, postage for non-free return 21 A high price for a test of an inappropriate from the outset device.
