I just finished my yard with my Worx Trivac.
I love it. I've had it for about three years now and abuse the hell out of it but the plastic fan is still intact and the unit is running great!
I didn't really like it when I first got it since I was expecting miracles from it. I have since learned that it's not meant to replace a rake but it's great for clearing out and sucking up leaves on my deck, in my driveway, in the street and in tough corners.
off topic:
Today was the first time I did my yard without a rake. I had just read that mulching leaves is actually good for your lawn. So instead, I just ran over everything with my lawnmower and sucked up the rest with the Worx.
