how strange,i did refer in my post to being better suited to repetitive work,by definition,commercial.the original post stated that he was looking for" maximum height "and that weight was a factor.I thi nk if you read my post with close regards to the original i have answered precisely what was asked,in fact you agree with some of my points.I do not use a modular on domestic for the same reasons you state but some cleaners do ,personal choice i suppose,and how your work is organised. apology accepted.!
