Somethings that i noticed when we switched over.
First clean took a lifetime,
We would have done a council house 10mins trad, first wash wfp took 15mins roughly. (More on the awkard ones)
Second clean takes a bit of time too.
After that 90% of houses were a doddle.
Between the 2 of us we find that we can get 4 council houses done now in 20mins, and not near as tired as we would have been previously.
a coupel of things i would mention, on a scorching hot day, give any hot windows a better than normal rinsing, and avoid frame vents like the plague.
