A floor care appliance such as a vacuum cleaner (10) is provided with a filtration bag changing assembly (300) located in the filtration compartment (fig 2, 220). A supply of filtration material is packaged in a container (320) in the form of a continuous tube (330) to be fed into the filtration compartment (fig 2, 220). A sealing and cutting assembly (350) seals the tube at the lower end after a bag is fed into the filtration compartment (fig 2, 220). Once a filtration bag is full, a new filtration bag is pulled in to place with the lower end of the tube being sealed and the old filtration bag being cut from the tube by a cutter. A pair of opposing heating elements are used to seal the opposing sidewalls (330a, 330b) of the tube together to form the filtration bag. The free end of the tube is fluidly connected to the suction nozzle by a connector and a dirt duct.
