I have the Airflex turbo.Just had it less than a week.I have a 400 litre upright baffled water tank that I use for my window cleaning.
My intention was to use the airflex as a van mount.Tryed it today,trouble was the intake hose is not longer enough,although the machine is right next to the tank.
Did manage to run as a van mount as an experiment, using a couple of 25 litre water containers.Stood the container on a plastic foot stool to give it a bit of extra height and the placed the intake hose into the container.
Need speak to Matt about extending the intake hose.Very pleased with the machine,used it Monday on a hotel clean,30 rooms cleaned.Set up one end of corridor,run of 75ft+ of hose.
Whatever size tank you do get make sure it is baffled.
