The invention provides a road sweeper which breaks through the structure form of a traditional road sweeper. Under the action of exhaust force of an exhaust fan, dust swept up from the ground can enter a dustbin along with air through a conveying device, the dust and air in the dustbin enter dust removal filter drums together through an exhaust opening of the dustbin; the air mixed with the dust is filtered by the dust removal filter drums, so that the dust is filtered out of the dust removal filter drums, and then the dust gathered outside the dust removal filter drums is stirred to fall in the dustbin through a stirring device; and all the dust is taken as garbage to be adsorbed, and clean air passes through the dust removal filter drums and then is exhausted to the outside through an outlet of the exhaust fan. When the road sweeper encounters with obstacles which cannot be swept away, main brushes swing upwards with the pivot position of a swing arm and the conveying device as a rotating point through the swing arm, so that the main brushes float vertically in a self-adaption manner according to road conditions, and the main brushes are prevented from being damaged. After the road sweeper encounters with large garbage, a first elastic baffle can be upwards lifted by a lifting mechanism so that the large garbage can smoothly enter main brush shells and then be swept away by the main brushes.
