The mayor organized the event to fulfill a pledge to clean up the city, which he had described during the campaign as being a "filthy mess."
An estimated 15,000 volunteers participated - about 5,000 more than expected.
Nutter also said Tuesday that 186 abandoned cars were towed and more than two dozen park sites were tidied.
The mayor himself helped out on Saturday by raking leaves, tossing out trash and planting a tree. He then welcomed volunteers to a barbecue at the Lincoln Financial Field football stadium.
