Yes, and I've got 5 years to go till I pack it all in mate. Looked at WFP, and it's next to useless here in ze Fatherland. Ladders on domestics on German domestics are hardly needed. All windows open inwards, and are cleaned both sides, on appointment.
We clean another 200 plus Brit/MOD custies on a 6 weekly basis too, but they are only possible using trolly or back pack, as most are terraced.
So, yes I'm trad, and I clean inside and out, because I can do both. Where-as, some people claim to be tradesmen and windies, but can't clean insides.
Like a plumber who can only fit 1/4 pipes in straight lines, or bricklayers that can't do rightangle corners.
The arrogance of a windy, that can't clean insides without a Kärcher housewives tool is really funny to me. To assume all tradders are thick and skint, just shows how far some dense people are up their own backsides mate. There are, thankfully, only a few on here. They, and the rest of us know who they are.
