ABSTRACT:
A floor-cleaning machine which can be driven over the floor, includes a driven brush for sweeping the floor to be cleaned. The brush picks up dirt and debris from the floor and carries it, assisted by forced air flow, in an overhead motion and through a transfer duct to a pair of dirt containers in the form of buckets located side-by-side at the rear of the machine. A manual linkage at the rear of the machine moves a pivoted carrier frame which holds the dirt containers, between a raised use position in which the upper rims of the dirt containers are sealed to the machine for collection of debris, and a lowered access position for removal of the containers. Each container is independently accessible for emptying, and includes a bail-type handle pivotally attached such that a bucket, the opening of which faces forwardly and upwardly in the use position, extends generally horizontal when removed, to avoid spillage. Each container has a recess adjacent the inlet opening for receiving the handle in the operating position.
