Abstract
A mobile litter pickup vehicle has a pair of forward corner brushes independently mounted on articulated arms so that the brushes may be moved in the event an obstacle is encountered to avoid damage to the brushes or to the object. An air recirculating system is employed for prolonging the life of the final outlet filter, and an impermeable trash bag may be used for disposing of the contents of a primary scrim collection bag.
