An apparatus comprises a main hopper having a surface cleaning configuration and a sander-salter configuration. In the surface cleaning configuration, the main hopper has a debris-laden airflow ingress, an airflow egress, and a debris dumping egress, and is sealed to the ambient surroundings other than the debris-laden airflow ingress and the airflow egress. In the sander-salter configuration, the main hopper has a sander and salt receiving ingress and a sand and salt egress. In use, in the surface cleaning configuration, the debris-laden air enters the main hopper through the debris-laden airflow ingress, air exits the main hopper through the airflow egress, and the debris exits the main hopper through the debris dumping egress. In use, in the sander-salter configuration, the sand and salt enter the main hopper through the sander and salt receiving ingress, and the sand and salt exit the main hopper through the sand and salt egress.
