Abstract: A filter arrangement for a vacuum cleaning appliance includes: a filter enclosure having an enclosure opening; a filter configured to be received through the enclosure opening into the filter enclosure in an insertion direction; and retention means operable between latched and unlatched states for releasably retaining the filter in the filter enclosure. The filter includes an actuation portion configured to operate the retention means, wherein the actuation portion is moveable between at least first and second positions and is biased towards the second position. When the filter is in the filter enclosure, movement of the actuation portion in the insertion direction from the first position to a depressed position transitions the retention means to the unlatched state, whereinafter the actuation portion is moved to the second position in which at least a part of the actuation portion is elevated above the enclosure opening.

Abstract: A circuit includes a controller circuit configured to receive an output voltage of a converter and adjust a switching frequency of the converter in response to a status of an output load and an output load sensing circuit configured to determine the status of the output load and provide the peak current to the controller circuit. The output load sensing circuit may include a first timer configured to provide a delayed first signal to a peak current control in response to the output load being a heavy load. A second timer may be configured to provide a delayed second signal to the peak current control in response to the output load being a light load. The peak current control may be configured to adjust a peak current based on the received first signal and the second signal and configured to provide the peak current to the controller circuit.

Abstract: A vacuum cleaner comprising a main body and a cyclonic separating apparatus. The separating apparatus comprises a dirt collection chamber and a baffle arrangement, and is mounted within the main body such that a first part of the dirt collection chamber is obscured and a second part of the dirt collection chamber is visible during normal use. The baffle arrangement is positioned within the dirt collection chamber such that, during use, an airflow moving within the dirt collection chamber is disrupted by the baffle arrangement causing dirt to collect preferentially in the second part.
