This product does what it says it cleaned my flags thoroughly. One problem was they don't tell you to be extremely carefully with the hose, only had the product for one month and the hose got a puncture from being moved along the flags outside. You are unable to repair it yourself, and it is not guaranteed. Rang the manufacturer, they are getting loads of calls from customers with the same problem. Had to pay a further £22 plus p & p for a replacement. They should either stress to people to put an additonal cover around the hose, or come up with some sort of solution. The product does what it says, but the hose was expensive replacement only used it twice!!!
