A laundry dryer comprising: • a cabinet including a plinth portion defining an inner plinth volume internal to the cabinet; • a first door arranged in the plinth portion of the cabinet; • a drum rotatably supported in the cabinet; • a duct defining a flow passage for process air exiting the drum; • a filter assembly (30, 30', 30", 80) positioned in a duct section located in the inner plinth volume so as to filter process air flowing therein, said filter assembly being at least partly located behind the first door; • said filter assembly (30, 30', 30", 80) including: o a frame defining an inner frame volume and having a frame shape; o a filter supported by the frame and defining a first filtering surface; o a cleaning device positioned within said inner frame volume for cleaning the first filtering surface including a slidable wiper to wipe the first filtering surface; o said slidable wiper having a shape mating the frame shape of the inner frame volume so that it can be translated with respect to the frame so as to wipe the first filtering surface, said cleaning device further including a fluff collector apt to collect filtered material removed from the first filtering surface when the wiper is translated onto such first filtering surface; characterized in that said fluff collector is integral to said slidable wiper. • a cabinet including a plinth portion defining an inner plinth volume internal to the cabinet; • a first door arranged in the plinth portion of the cabinet; • a drum rotatably supported in the cabinet; • a duct defining a flow passage for process air exiting the drum; • a filter assembly (30, 30', 30", 80) positioned in a duct section located in the inner plinth volume so as to filter process air flowing therein, said filter assembly being at least partly located behind the first door; • said filter assembly (30, 30', 30", 80) including: o a frame defining an inner frame volume and having a frame shape; o a filter supported by the frame and defining a first filtering surface; o a cleaning device positioned within said inner frame volume for cleaning the first filtering surface including a slidable wiper to wipe the first filtering surface; o said slidable wiper having a shape mating the frame shape of the inner frame volume so that it can be translated with respect to the frame so as to wipe the first filtering surface, said cleaning device further including a fluff collector apt to collect filtered material removed from the first filtering surface when the wiper is translated onto such first filtering surface; o a frame defining an inner frame volume and having a frame shape; o a filter supported by the frame and defining a first filtering surface; o a cleaning device positioned within said inner frame volume for cleaning the first filtering surface including a slidable wiper to wipe the first filtering surface; o said slidable wiper having a shape mating the frame shape of the inner frame volume so that it can be translated with respect to the frame so as to wipe the first filtering surface, said cleaning device further including a fluff collector apt to collect filtered material removed from the first filtering surface when the wiper is translated onto such first filtering surface;
