My house is clean, I work full time, but I clean my house all the time, I usually do laundry every 2nd day, my girls will vacuum and wash the floors, I do bathrooms, change sheets on beds every weekend etc. I clean my kitchen every time I use it. Kids call me a clean freak, it doesn't take long if you are on top of it.
My house is lived in. Clean but occasionally cluttered. With 2 teens, I just close their bedroom doors . They are good about keeping their rooms clean-no food, dirty dishes, changing sheets, etc.
