I
I get my extension wands and vacuum ceiling fans and dusting areas with horsehair dusting brush. I then vacuum furthest area of the room from the plug in and work towards where machine is plugged in.
I dust first so if any dusts floats onto the floor I can clean it. The flooring is different. I do rugs and then oak floors. I move chairs or furniture on rugs vacuum and then put items back. I then follow the flow of the power cord.
I use rainbows 10 inch floor brush for dusting. I use power nozzle everywhere on all surfaces not dusted. I use turbo spin brush on the stairs. I do sometimes use a handvac on the stairs.
