I have that problem with Candra, except she will just got to her room and play or make up some of the most feeble excuses ever. My spouse is not helping either which is probably why Candra doesn't help too. My problem with Rob is that he uses the "I work all day" excuse.
I would call a family meeting. You need help to keep the place clean. If your husband is also not helping, tell him how much extra energy you'll have at night.
He is a roll model too, and kids folow the laziest parent. And this is about your saniity.
Good luck.
