I'm not sure what all the fuss is about, but before I went wfp I read all these threads on how much time it takes to get up to speed. Well I'm not sure if I'm an exception or what, but in my second week I smashed my daily earnings record, and that with 1,5hr to spare.
Yes I had done a lot of research on how to quickly but efficiently clean with a wfp, but what is all this talk about only 40% faster for months etc? In my first month I was already twice as fast? And I was very quick traditional.
I put a lot of that time saving to excellent tools like the SL-X, but still wfp has been an absolute dream for me, it's so easy, I earn atleast a good 100-150 more a day now. With perfect results (I do a lot of insides aswell, and gives you the perfect chance to check the windows).
Only thing that I hate, is top seals that hold drips, not the seals were the water just flows off easily they are easy, but the ones that when you rinse or scrub the top, they just sit there on the seal, they almost always come down as runs after you've finished. And even with oxidized frames, I can still do a good job, thanks to the advice on this forum.
Customers absolutely love it, I haven't had a bad remark, (only one who was furious, last wfp'er they ditched cuz he did a rubbish job, and took me on, because I used trad tools, then switched over, and she was absolutely mad, how could you etc, the windows look terrible, went over there, two windows were bad, builders decided to wash them with a hosepipe, probably washed the brickwork or something, even told the owner I was only there for 20min, while I was there for 2.5hr!! Cleaned them next time, customer was there, and she was delighted, absolutely marvellous how clean you get them she said, big big smile on her face, now that made me happy).
Anyway, customers have been properly trained with introduction letters, and it really helps to sell the system with realistic remarks, not promote is a magic wand, but things like getting your frames cleaned every time really made them smile. Also be careful to not say, there can be spotting in the beginning etc, you need to find the middle way, be honest to your customers about the system, do not create expectations that you cannot live up to. Customers love it, very happy.
I probably should thank this forum with everyone who answered questions, otherwise I'd never come this far.
