Abstract: A cleaner head including suction chamber having a suction opening; an agitator including a hollow body and supported the suction chamber by a support member, the support member having a first end that is fixed to a side wall of the suction chamber,and second end that free and over which the hollow body of the agitator can be slideably received; and a drive assembly forming part of the support member, and arranged to rotate the agitator about an axis. The fixed end of the support member is pivotal fixed to the side all of the suctionchamber such that the free end of the support member, together with the agitator supported thereon, can be pivoted to protrude out frome suction opening, to allow the agitator o be removed and replaced.

Abstract: The present invention relates to a regenerative filter comprising, a length of material having a first support tail and a filter portion, a first end of the material being wound around a first perforated support to form a first scroll type filter through which air to be filtered can pass, and a second end of the material being fixed to a filter support, the regenerative filter being arranged such that the material is movable in both directions between the first perforated support and the filter support, passing through a filter regenerator generator as it moves between them, the first end of the material forms the first support tail which extends from the first perforated support to at least the filter regenerator when the material is unwound from the first perforated support, the first support tail having a more open structure than the structure of the filter portion.

Abstract: A regenerative filter having a length of filter material, first and second perforated filter supports, a filter regenerator, and an intermediate duct, a first end of the filter material being wound around the first perforated filter support to form a first scroll type filter through which air to be filtered can pass, a second end of the filter material being wound around the second perforated filter support to form a second scroll type filter through which air to be filtered can pass, the filter material is movable in both directions between the first and second perforated filter supports by passing a single layer of filter material through the filter regenerator as it moves between them, the intermediate duct being arranged to take airflow which has passed through the first scroll type filter to the second scroll type filter for filtration during use of the regenerative filter.
