Summary: I HATE housework but like a clean house....so cleaning gadgets are the way to go for me ! I was very pleasantly surprised when using this for the first time,with just Windex as the cleaner. Today I went all out. Live in the country so windows get a lot of dirt from windstorms and my dogs. So I used a bucket of soapy COLD water ( used Palmolive dish detergent after reading various cleaning blogs online) and a mop and scrubbed the outside of some very dirty windows.
Summary: I was so hoping this thing would work. Sadly, it doesn't. The videos really show you what you want to see, reality is different. Windows are still streaky and the think doesn't really suck up the water. Too expensive for something that doesn't work. Save your money.
