A debris collector comprises a chassis (1) and an impeller (14) for establishing a flow of air. A duct (4, 5) is supported by the chassis (1) for conveying loose material entrained in a stream of air generated by the impeller (14) towards a proximal region of the duct from a collection mouth (10) at a distal end thereof. The impeller (14) is mounted in a housing (3) at the proximal end of the duct (4, 5), the housing being pivotably attached to the chassis (1) in such a manner that pivotal movement of the housing away from the chassis exposes the impeller and the downstream end of the duct (4, 5) for cleaning purposes.
