I use my trad tools fairly often Adam, I’ve got a car show room, so inside requires squeegee, and several other jobs that need insides done, but I charge good amounts so it’s worth it.
For me, it’s how I learnt the ‘trade’ so it’s no bother, but I don’t enjoy it.
Once you’ve been wfp, trad becomes a nuisance. To think I did it trad for 8 years before going WFP. I should have gone wfp much earlier than I did (2014).
There is an art to trad cleaning though, I do quite like the fact that a lot of newer window cleaners can’t use trad tools, it does create a small niche area for inside work, but you do have to charge well for it, because it takes ages and is annoying!
You’re right though, you can have a perfectly good round without ever touching a squeegee.
