Hello,
Our website should be shown below, we use the 1250 watt vacs all the time and they do the job. We started out with big vacs but then tested these machines and found they did the same job for a fraction of the price, also if you wanted a generator you only need a 2.4kva machine which can be lifted by one man and cost a lot less. These kits are designed for window cleaners who don't necessarily do a lot a jobs per year but want to do a few without the need to climb ladders! We've used them on houses, apartment blocks and schools and have always got the job done and we don't carry ladders.
