like Mike, just over an hour.
Radek,
3 - 4 hours?
Just think how much more money you could make if you became more efficient
think how much more better your work can be if you do it correct
TM or portable, no matter, 1,5-2 hrs is not possibe if not missing most of the steps.
ps. I am not slow, can not me more efficient, no way, just not possible. Working as a TM with the storm, water tanks, automatic empty, quick filling with the pump inside the water tank, hose reels, remote control etc. Set up is only a bit longer becouse two power cables (max. 2 min).
Even if the job is just "refreshing" I am still doing agitation (then with Sebo, not the TM4), and 2,5 hrs would be min for the best fastest jobs.
I am sure that all you do is spraiyng the presprays, quick agitate (if any) with the grooming brush and extraction, becouse customer will see the different anyway not looking deep into the carpet.
If one person off course.
Simon, your times are probably true, you work as a two man team at least.
