Hi Mark
Ive used mine on most and find it fine,most fabrics aren't that delicate that it can't be used on them in fact I can't think of one where I wouldn't have.That's not to say that I won't come across one

I dont find it cumbersome at all and for me,it cuts down a lot of the work involved in agitation and finishing off.
But I can see how it wouldn't be for everyone as it's not your every day bit of kit and takes a bit of getting used to.
