i use it as a vac . i am glad you changed to a metal grinding blade instead of plastic . the vac does a great job it grinds the leaves to almost nothing . i really liked the variable speed so you don't vac up small rocks or big pieces of mulch . it's a very good blower vac that's why i gave it five stars .
I have been thru 2 of the model 151.30381. They last for a couple months of minor usage and quit. Yes, there is a warranty, but still poor quality. This is ridiculous.
