15 grand. +vat. +900 for each pole. Can't do frames unless you add brisstle attatchment to the hoover head thing. If you do it leaves 20 % of the water behind, so wet windows.
The hosereel is one of those massive ones you see in trailers sometimes, the huge black stuff on a reel five feet in diametre, you know the stuff. So you need a huge van even though the machine is only normal size. It can go in a normal transit or even doblo, but needs a trailer for the reel. You still need the normal hose too, so pain in the butt.
It looks swish, the vacuum created smashes the water (hot) into the window and cleans it, so just rubber blades with the water jets in between and the suction hole. The water goes through the pole (captured water). The machine is two 300 litre tanks. The retrieved water is cleaner than tap water still (the bigger bits are captured before it goes back in the tank. That water is re-filtered. 300 litres will last one month I was told.
Also, it's not switched on, and the rep said it makes a racket.
It will cost around 20k in total + bigger van, plus it can't do frames.
What a waste of my time.
