Abstract
A separator for a cleaning device, the separator comprising: a housing that encloses a separating volume, the housing comprising an inlet for receiving a fluid flow containing entrained debris into the separating volume, and an outlet for discharging a filtered fluid flow output from the separating volume; a filter screen disposed on or in the housing to define part of a boundary of the separating volume, the filter screen being configured to retain the debris in the separating volume while allowing air to exit the separating volume to flow to the outlet; and a cleaning conduit configured to convey fluid towards the filter screen, the cleaning conduit comprising a jet-forming outlet that is configured to direct a fluid jet at or across the filter screen to remove debris attached to the filter screen.
