We're looking at WFP as an option on a new commercial contract that we have, rather than subbing out.
Visited a supplier on Monday to discuss potential requirements. The main points picked on were: -
1) Trailer systems are no good. This supplier did one and was honest enough to say that they'd prefer not to do another. The problem being the lack of suspension on the trailer leads to the system vibrating apart!!!
2) Results - Whilst there I spoke to a window cleaner who made the switch last year. Really nice and helpful guy. He said that the results were not as good, nor would ever be as good when using WFP instead of Trad. The problem for him was the frames, especially on old properties (most of his round being 40 years + old). The supplier was party to this discussion and didn't disagree, infact he nodded.
Looking for honest opinions from anyone and everyone with WFP experience, especially trailer owners and those that have had difficulties making the transition and have either reverted or persevered and succeeded.
