A floor care appliance comprises a first dirt collecting system 300 removably mounted in a housing 200, and a second dirt collecting system (400) interchangeable with the first. The first dirt collecting system comprises a dirt cup 350 having two chambers 316, 318 arranged adjacent to each other, divided by an apertured wall 312 allowing communication therebetween. The apertured wall prevents coarse particles from exiting the first of the two chambers. The second chamber has a primary filter 381 for filtering fine particles, which may include at least one layer of expanded polytetrafluoroethene (PTFE). The second dirt collecting system may include a bag container (450) and a filtration bag (412), the bag including a layer of expanded PTFE. The bag container may be translucent. The dirt collecting systems are mounted sidewardly in a recess in the housing. There are seven other inventions embodied in further independent claims, each characterised by a differing arrangement of dirt container, filtration bag, and filter.
