I am married with two boys a cat and a dog (shedding golden retriever). Once you get it cleaned it is all about maintnance. A little here, a little there. Make a schedule and post it. If your kids are old enough, give them an assignment also.
For instance. Monday- you clean kitchen she does laundry.
Tuesday- you vacum she dusts.
Wednesday- you laundry she cleans bathroom.
