If WFP is slower for any WC they have the wrong type of work,for the odd job i do use ladders but most of my houses are large and with WFP it takes half the time it used to with ladders,at least half the time.I do a number of houses that used to take 3 of us 2.5 hours,i can now do it on my own in 1.5 hours.The safty is a bonus the more work you can do with WFP is surprising over the course of a week-month,the real difference is seen in time saving after using it for about a year,forget all the rubbish people telling you that after a month you`ll be doing a months work in 2weeks cos you wont be,but that would be possible after you have a years experience under your belt.
