Abstract (en)
In the field of handheld vacuum cleaners, a vacuum cleaner unit (4) is provided that comprises a motor-fan aggregate (10) and a main body housing (30) accommodating the motor-fan aggregate (10), wherein a sleeve-shaped wall (31) of the main body housing (30) is arranged to surround at a distance an aggregate housing (20), at an exterior of the vacuum cleaner unit (4). The aggregate housing (20) has at least one aggregate air outlet opening (25), and the sleeve-shaped wall (31) has at least one main air outlet opening (36). An air channel (40) from the at least one aggregate air outlet opening (25) to the at least one main air outlet opening (36) comprises space that is present between an exterior surface (27) of the aggregate housing (20) and an interior surface (37) of the sleeve-shaped wall (31), which contributes to reduction of noise in the vacuum cleaner unit (4).
