Hi Dale, we've used Skyvac systems for 10 + years.
You get what you pay for great machines, poles and support.
We've used the Industrial models and recently upgraded to the Interceptor petrol models as we have large enough volume of business. I have a friend who runs a window cleaning business and he uses the Skyvac Atom systems seems like there's plenty of choice. I'm sure that there are other competing machines but I can only comment on the ones we've used.
Hope this helps .... its a challenging industry so you can usually find lightly used machines on EBay too.
Kind regards Keith
