In my opinion the unit just plain sucks! Ok, it does pick up stuff pretty well as was enumerated above, but I have had mine clog with some frequency doing leaves. If the leaves are wet you have to slow down, and it will eventually clog in my experience. The unit is a monster, at takes up to much space for me, makes the machine so wide like John said, and is a hinderence to vision. I would do as John said and get a side bagger, it would give you more flexibility and hold nearly as much. Those cans really don't hold a bunch of material, and can be a big pain to put on and take off. I will never again buy a unit like this again for a walkbehind.
I wish you well.
