WFP, trad...does it really matter?, it's only cleaning windows is'nt it.
They are tools of the trade but the divide is almost gang like....mines better than yours....can anyone really say anyone of the systems is better for all users?
Trad can be quicker and as safe as wfp and vicky verky...personally I doubt I could be as fast with trad as wfp on my working week...but individual houses...yup faster with trad.
The end of the day is it about an individuals 'acceptable' turnover against, expenses, time worked, saftey and of course 'how we feel'....if we can tick most of those boxes then we are truely fortunate souls.
Have a great week
Dave.
