Surface treating appliance |
摘要 |
A surface treating appliance includes a first cyclonic separating unit including at least one first cyclone, and a second cyclonic separating unit located downstream from the first cyclonic separating unit and including a plurality of second cyclones arranged in parallel. The plurality of second cyclones is divided into at least a first set of second cyclones arranged about an axis, and a second set of second cyclones, the first set of second cyclones extending about the second set of second cyclones. Each second cyclone has a longitudinal axis, with the longitudinal axes of the first set of second cyclones being arranged at a first angle to said axis, and the longitudinal axes of the second set of second cyclones being arranged at a second angle to said axis, and wherein the first angle is greater than the second angle. |

1. A surface treating appliance comprising:
a first cyclonic separating unit including at least one first cyclone; and a second cyclonic separating unit located downstream from the first cyclonic separating unit and including a plurality of second cyclones arranged in parallel; the plurality of second cyclones being divided into at least a first set of second cyclones arranged about an axis, and a second set of second cyclones, the first set of second cyclones extending about, and being located at least partially above, the second set of second cyclones; each second cyclone having a longitudinal axis; the longitudinal axes of the first set of second cyclones being arranged at a first angle to said axis, and the longitudinal axes of the second set of second cyclones being arranged at a second angle to said axis, and wherein the first angle is greater than the second angle. |
