Abstract
Vacuum cleaner, comprising a tube having a first diameter, a hose having a second diameter exceeding the first diameter by at least 15%, and a transition piece (T) having a first end (1) arranged for being connected to the tube, and a second end (2) arranged for being connected to the hose, wherein the transition piece (T) has a curved part that has a non-circular cross-section, the curved part having a first part (I) in which in a direction from the first end (1) to the second end (2), a first dimension (R1) of the cross-section increases to a diameter exceeding the first diameter by 15%, the first dimension (R1) being in a radial direction of the curved part, while a second dimension (R2) of the cross-section, perpendicular to the first dimension (R1), does not exceed the first diameter by more than 10%. Preferably, the transition piece (T) has a second part (II), between the first part (I) and the second end (2), the second part (II) having a non-circular cross-section where the second part (II) meets the first part (I), and a circular cross-section where the second part meets the second end (2). Advantageously, in the first part (I), in a direction from the first end (1) to the…
