Hello, thank you for your feedback. Based on it, our supplier contacted us and would like to respond below.
"Hello, we're sorry that your first experience with the robotic window cleaner wasn't a positive one. Below are a few tips that may improve the cleaning results. The mopping pads need to be changed during cleaning. If dirty circles remain on the window after cleaning, the mopping pads are already dirty and need to be washed again. Before cleaning, you can spray the windows with a standard window cleaning product, which will help the robot polish the glass. For heavily soiled windows, we recommend first letting the robot clean the window with a water programme, then changing the pads and letting the robot polish the glass without the water function turned on. Should you have any questions, please don't hesitate to contact us at
[email protected]. Kind regards, Sencor."
Thank you and have a nice day, Ondřej - Alza Expert
