I've been thinking about buying a leaf vac this year to help with leaf clean-ups and other clean-up jobs throughout the year. To give you the background, we don't get one huge drop in a short period where you have to deal with a massive amount of leaves at one time. Leaves steadily drop from one tree or another for 4 months or more. Anyway, I rented a Billy Goat leaf vac to see how it worked. I could see the potential of the machine but the problem was that on an empty bag it would it vacuum great till the bag was about a 1/4 full then it went downhill from there. With the bag filling from the bottom that's not surprising. The second problem was dumping, trying to zip and unzip the bag was a pain and it was hard to get the leaves out. If the machine vac'd strong from an empty bag till full and was easy to dump I think I'd buy one. I looked at the Little Wonder vac and it fills from the top and the bag has an open top for dumping. For those who have used the Little Wonder, does it vac strong till the bag is full? If it does I may go with one of those instead.
