My coop is 8 x 8 with an attached 320 sq ft run with a top. At the moment I have 14 hens. I built a droppings pit-type roost, which works quite well and is easy to clean out through a trap door on the outside. I rigged a tarp over the nesting boxes that I can simply lower at night to keep hens from nesting and defecating in them and on them. Things usually stay pretty clean inside the coop, although we've been experiencing a prolonged period of miserable rainy weather, so I've had to do a little bit of spot cleaning. I clean the entire coop thoroughly about twice a year. I do limited free-ranging (hawks), which helps some in keeping the run clean. Fortunately it stays dry because it's on a slight slope. I also rake the run occasionally. On a daily basis, I guess I spend about 5-10 minutes cleaning the coop (scraping the poop off the roost, picking up any poop in the bedding, etc.). I clean out the droppings pit every day or every other day, so that the mess doesn't build up and smell. If I do it everyday, it's less than a shovel full.
