Vacuum cleaner

Abstract

A vacuum cleaner (1, fig.1) comprising a dirt separator 400 with a filter assembly 405 and a drive assembly 450 for dislodging dirt and regenerating a filter 410 of the filter assembly by agitating, moving, wobbling or shaking it, wherein the drive assembly is activated by a controller. The drive assembly may comprise an electric motor (451, fig.50) coupled to the filter via a drive shaft (446, fig.48) with an eccentric mass (455, fig.48). The controller, which may be a microcontroller unit or a processing unit, may adjust the duration, speed, interval and / or frequency of the drive based on detection of opening of a bin base and / or dust load of the filter (i.e., blocking or blinding of the filter). Preferably, a bridge 440 and the filter are moved repeatedly along a closed path (458, fig.52), which is elliptical and eccentric. A primary dirt separator (210, fig.8) may be located upstream of the dirt separator within a bin (100, fig.8). Figure 36
