We have zero carpet in the home, but I vacuum behind/underneath things about once a week. H has a very large gem and mineral collection full of large pieces that need to be vacuumed around every week. It probably take about 30 minutes to get everything vacuumed. I sweep the main living areas (kitchen, living room ,and hall) daily and mop once or twice per week. If I'm doing ALL of the floors (sweeping and mopping) it takes about an hour or so. Our house is 1400 sq ft.
