I work with my Missis; the way we work is that I use her for all our compact or large stuff. On residential we'll split up and work on separate houses.
I normally save my drive-betweens up - I don't think it's worth both of us doing them together - and when she has a day off, or when I drop her off and pick up more water, I'll head out and do the 'fanny about stuff' by myself.
Occasionally she will help with a 'drive between', normally where we've compact work and a couple of spare jobs near them. I normally just pole these myself but she helps with setting up and moves my hose about so I can work really quickly without any messing.
Also, don't worry about drips; they generally don't interfere with the quality of the clean.
