"Having previously cleaned the patio with a pressure washer ,without anyform of attachment, I vowed never to do it again and I was sceptical whether anything could actually do it effectively and safely. Well this little beauty does exactly what is required. It connects with ease, is lightweight and after a couple of trial runs I even had the missus having a go. The fixed brush around the periphery acts as both a curtain and scrubber and prevents any kind of blowback and contains both the debris and the spray. It is as simple as using a vacuum and my patio was transformed in half an hour. I thought it was rather pricey, and this may well put many people off, but having used it, to great effect, it is worth every penny. Highly recommended"
