Okay, these are my 2 cents:
I own a Washtec brush machine which is very similar to an Istobal. Here is what I like and what I hate and why I would NOT buy another of those machines again:
I love:
The cleaning quality (gentle & thorough)
You can program every bit and piece of that software
Low energy and water consumption
Perfect for a dealership or rental car company where the staff operates the machine.
I hate:
The narrow guide rails (people drive up and down and then the machine stops during the wash)
The guide rails in general as they are either too low and people drive over them or if you get bigger ones their steel might damage some rims. I replaced mine now with plastic wheel stops for car parks. Too early to say.
The complexity of this German made machine. I.e. why on earth do you need to tilt your side brushes when you can just make the brush strains a bit longer at the top of the brush so it reaches the car? KISS - Keep It Simple, Stupid!
All frickin' galvanised: I replaced my contour dryer after the 3rd year of operation already due to rust. Nothing beats stainless.
Which brings me to the contour dryer: It is either me damaging the car antenna or the car antenna damaging my dryer if some idiot doesn't remove it beforehand. It depends how strong the antenna is.
and I have to babysit the machine all the time - not because the machine is bad but my lovely customers are. They go in with everything attached. I am very curios about the
www.cubewash.com This would be a nightmare with my machine: safe money for a new brush!
I would rather look at the
Washworld Profile Max or if that Cubewash ever gets out and was reliable....
