If you have a double story home and so cannot get to the high outside windows to clean.
I can help you with this amazing product.
The extension of the pole is long enough to clean high unusual windows.
The available configurations of the brush allows for cleaning at odd angles.
The bristles are strong enough to remove bird poo but made to not scratch your windows.
The results are so good because the water is filtered through many materials including resin in that scuba looking tank. So the water is at it’s purest form on your windows.
