I am lucky in that I work part-time and have several days off a week, but the days that I do work are very long days that start early and end late. On those days, I barely see my kids. I hardly touch the housework. I just try to survive. On the days I don't work, I try to catch up on housework - I'll be honest, my kids don't help with that much (yet), but it's a goal. I try to do some fun thing with them each weekend, even if it's just getting to a park in town.
My goal, at one point, was to pick one cleaning task to do each day so that it wouldn't all pile up but some things can't work on a schedule for our household - like laundry, dishes, vacuuming even (because we have 2 dogs and there is ALWAYS dog hair everywhere). So I just try to take a few minutes each night when the kids go to bed to tidy up and maybe take care of one chore - emptying dishwasher, wiping down counters, vacuuming, etc. And then the rest of the night I get to myself - because without my "me" time I'm no good to anyone!
I know none of that is really very helpful - honestly, I just keep myself afloat and call that good enough most of the time.
