power aside, i imagine the time saved unloading the machine, and buckets aswell as any rinse agents amd defoamers, bags of hoses and the heater -then filling emptying etc, then reloading it at the end.
Vs roll up , vac,prespray and agitate- then roll out desired hose, hook up wand, power on and off you go.
Would love a go on a tm for sure
