<p>A self-propelled cleaning vehicle (10) has two wander hoses (350), each covering an arc of at least about 180 degrees at each side of the vehicle (10). The wander hoses (350) are stowed unobtrusively in recessed portions of the vehicle (10) extending lengthwise thereof at upper and lower locations thereon. The upper portion of the wander hose (350) is below the maximum vehicle height (366). The hoses (350) are pivotable about upwardly extending axes (368, 370). Each hose has an articulated support structure (378, 380) which permits hose articulation about a second, spaced, upwardly extending axis (382), whereby the hose assembly (362, 364) can cover two arcs of movement, and can reach forwardly around the projecting cab structure.</p> |
