Start by taking off all removable cushions. Collect coins, bobby pins, and any other large detritus that may have fallen into the couch. Then clean up the solids. If you have pets, a lint roller can be especially helpful in removing fur. Using the upholstery attachment and crevice tool, vacuum each cushion and the couch itself, taking extra care with the places debris can settle, like the corners and seams. If you’re cleaning a delicate fabric like silk, be cognizant of the vacuum’s suction strength and rollers, and consider switching it to a lower setting or attachment if necessary.
