Though the cars make our life more convenient, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, they can cause disease and even death. Through investigation and research, the paper takes forth street cleaner as a solution to the air problem and in the meanwhile, city landscape is incorporated into the design of street cleaner. Considering its feasibility, the cleaner will be proposed to be fixed on pole of street lamp. Through the fixing method, the power supply of cleaner can either rely on the street lamp or wind energy and solar energy. The cleaner can both alleviate the city air pollution and be a city landscape and give a novel idea to control city air pollution.
