1.Clean top to bottom, left to right
An awesome tip for a faster clean is that you start from the left and work your way to the right, because this way you will cover the entire room instead of going from the couch to the window and then to the rug. This is a smart way of cleaning too, because, according to the experts, wiping the coffee table then cleaning the blinds is a great chance of moving the dust in the air. And what was the purpose? You will still have a dusty room.
Start from the top of the room, dust the ceiling, and then work your way to the bottom in order to eliminate the unnecessary work.
