If it goes through a tight corner, often remains are something. Even in corners you can not really sweep. Where it goes straight, but the result is good.
Our solution: Larger amounts of leaves are collected as usual. The dirt from the corners is swept into the center and then we go to the sweeper on the way. The result is good. While it is not faster than with a broom, but the result is at least as thorough and also back friendly.
