TL;DR: In this paper, a floor cleansing machine for industrial use is defined, comprising a chassis, a driver's seat, and auxiliary lateral ground supports arranged on mutually opposite sides with respect to the steerable central wheel.
Abstract: A floor cleansing machine (1), particularly for industrial use, comprising a chassis (2) which supports floor cleansing means (3) in a downward region; the chassis further defines a driver's seat (8) and is provided at the rear with at least one pair of lateral wheels (9) and at the front with a steerable central wheel (11); the chassis is provided with at least one pair of auxiliary lateral ground supports (13) which are arranged on mutually opposite sides with respect to the steerable central wheel (11).
TL;DR: In this paper, a floor wiper consisting of a brush supported by a supporting structure is connected to the chassis of a floor cleansing and drying machine and can be engaged by contact, with one of its lower edges against the floor to be cleaned, the brush being associated with a supporting body which can be coupled detachably to the supporting structure by snap-acting quick coupling means.
