Bought this for Christmas for my hubby. He's constantly whinging about the pool fence looking so dirty (hard to keep clean with kids jumping in the saltwater pool!) and we have floor to ceiling windows in our entire living space - which is also right next to said pool - that get equally dirty in a matter of a day or two. This has solved all our problems, and is quick and easy to use. Also bought the extension pole so we can get right to the top of the windows with ease. Sure beats paying to have them cleaned every month, and living with dirty windows for 2/3 of that time... We can just whip this out whenever we feel the urge, what a fabulous product!
