I am more or less the same as Roy (except I don't earn as much
)
I haven't had much in the way of problems, and I have found the amount of work I can get done in a day has increased by approx 25% overall.
You are obviously doing something wrong, both in the way you are using your WFP, and in the way you are selling it to your customers.
How much water are you using on each account?
Do you clean out the brush head regularly?
Is your brush a single or split type filament?
Is your brush jetted, or do you just have a couple of holes for the water to come out of?
What method do you use to clean a window?
What method do you use to unload and set up your WFP when you pull up to an account?
If you paid over £3,000 then I presume you do not have a trolley system, but is yours a van mount or trailer system?
It sounds like you would greatly benifit from one of the courses that are on offer, I think they are run by Craig Mowlam from Ionics (if I have that bit wrong, and without checking out other postings I'm not sure
others will correct me)
On some jobs you will be no quicker than using traditional methods, but they are generally tiny jobs, on most work you should be considerably quicker, the bigger the individual job, the quicker you will be.
