A hand-held vacuum cleaner with a container for the storage of dirt and debris therein. To provide improved efficiency and performance, the hand-held vacuum may employ a primary HEPA filter, a device for swirling a dirt and debris laden air flow and/or a mechanized filter cleaning device. Swirling may be employed to direct entrained dirt and debris in a desired direction relative to the container to slow the rate with which dirt and debris accumulates on the primary filter and/or to centrifugally remove dirt and debris from the air flow. Mechanized cleaning is employed to shake, scrape or otherwise remove accumulated dirt and debris from the primary filter.

Aspirateur à main avec un contenant pour stocker la poussière et les débris. Pour augmenter l'efficacité et la performance, l'aspirateur à main peut utiliser un filtre HEPA principal, un dispositif pour faire tourbillonner l'air chargé de poussière et de débris et/ou un dispositif mécanique de nettoyage du filtre. Le tourbillonnement peut servir à acheminer la poussière et les débris dans une direction souhaitée par rapport au contenant de façon à réduire la vitesse à laquelle la poussière et les débris s'accumulent dans le filtre principal et/ou à enlever par la force centrifuge la poussière et les débris du flux d'air. Le nettoyage mécanique consiste à secouer, à racler ou à enlever autrement la poussière et les débris accumulés sur le filtre principal.
