I think that there is still room for another water tank in the hot water frame that is up on top of the other water tank. hahahahaha
It is very creative and I still think that if they used hot water they would clean better but I guess it would not fit on top of all that stuff, maybe the next generation will have hot water.
I think that they are on the right track with the drivable, self-contained surface cleaner then the vacuum unit behind them.
It would be great if they could combine it all onto one machine, paint it white like those Cyclone machines, I really like those and those do have hot water but I have not seen one clean a dumpster pad or drive thru to see how good it can clean.
I have been thinking about what kind of vehicle could be made into one of these machines so it could have a large water tank, hot water and a vacuum system?
