The device is great. I actually just use the suction / chaff function because I equal soaking the blades off the floor. But that makes the device with flying colors. Even the long bamboo leaves that are blown away by the neighbors on my property (grmphl), swallows and shreds the thing easily. When I assembled the sucker, I felt like Rambo (Riesenwumme before the paunch). So, an additional fun factor for men: O). Actually, there's only one problem, but for which the manufacturer can not for me. For people around the 1,90m like me, the tube is too short (yeah - we know all; O)). This means that the rollers do not put on the floor and the vacuum cleaner must be maneuvered alone / held with force of the arm, and after a long time sucking the Cross reports. Perhaps there will even out a XXL version. The device is in any case recommended.
