Remove any protective covers, pillows and cushions off the microfiber couch; set them aside.
Place a soft brush attachment on the accessory hose of the vacuum cleaner. Sweep the dirt, debris and loose lint balls off the surface of the couch. You may need to make several passes across the same area to get the material clean, Make sure you clean the entire couch: the back, seat area, the arms, sides and front. Sweep the pillows and cushions, if there are any.
Use a sticky lint roller to remove lint balls from the couch. Run the sticky end of the roller back and forth across the fabric to pick them up. When the surface of the roller isn't sticky anymore, rinse it off under running water to clean it. If the roller is a paper roll, peel off the soiled layer and discard it. Finally, use the sticky lint roller to clean off the pillows and cushions, if applicable.
