Summary: I wanted to buy one of these for some time but decided that it was too expensive and then Very had a good discount so I got one. It works well, is light and easy to use and it is quick to clean windows.
Pros: Perfect streak free finish everytime and because the windows have been thoroughly cleaned, they stay clean so much longer., I bought the WV50, you don't need the expensive "extras" equivalents can be bought far more cheaply.
Summary: This is a brilliant window cleaning aid, I have tried numerous squeegees and things before but none came anywhere near the performance of this Karcher, I purchased it with a discount code making it even better value. Having said that, it is worth the normal full price.
Summary: I bought this product a couple of months ago and can't praise it enough. It takes all the hard work out of cleaning windows and they come up sparkling clean! My mum and sister also purchased one each after using mine. Definitely a good investment.
