Don't start a room by wiping the coffee table, then clean the blinds, and seeing the dust from the blinds coat your newly clean coffee table. Sardone says to start at the top of the room, such as dusting a ceiling fan, and work down to the floor to eliminate redundant work.
Likewise, cleaning left to right ensures that you cover the entire room instead of darting from place to place.
"Most people see something and clean it, then they look up and see something else and clean it, and the dirt falls down on what you just cleaned," Sardone says. "If you work top to bottom and left to right, you're working once instead of cleaning areas you've just cleaned."
