As you see on the plug, this vacuum cleaner is effective. But in addition it is solid (steel pipe), handy (adjustable tube height, 360 ° rotation of the suction duct, large wheels). The bag is a large capacity (5 liters) which prohibits the storage of accessories in the vacuum cleaner (they can be stored at the base of the suction tube and here is the main complaint). There is a range above with a more efficient suction brush (apparently) but really much more!
