    Powerful, well built, does a excellence job of picking up leaves, pine needles. Easy to change from vacuum to blower. I
    This is my first day to own. Put it together in 5 min. I normally wouldn't write a review on the first day but that's how impressed I am with the performance. If I never used it again it paid for itself today. I picked up a whole winters leaf accumulation. If I had hired someone it would have cost me the price of the Blower. Most impressed with the metal mulching blade. I picked up hundreds of Sycamore balls in my flower beds. Hate that tree. Checked the blade and no damage. Like any tool knowing how to use and care for it is the key. Also like the variable speed switch as lower speed lets me pickup leaves and leave the mulch in the flower bed. Don't be afraid to buy this product where you can use a electric cord. If it lasts a year I will be ecstatic. I wear out a gas trimmer/blower/edger every year with the yard and Blvd I keep so using this blower/mulcher only in my yard should last a long time.

    The mulcher. The metal mulcher does a great job of reducing the leaves and small debris.


    Nothing yet.

    Awesome product
    I've owned numerous leaf vac/blowers over the years. I don't post reviews, but in this case felt I had a duty to share my thoughts. AWESOME. I have large oak trees on my property. Leaf blowing / collection is an annual event. The blower is the best I've used. The vacuum works really well also. The best part is the optional collection system. A cloth cover fits over a trash container. I use a 32 gallon round plastic container. I put the plastic bag inside, then the B&D cloth cover. Connect their provided hose to the top. Connect the other end of the hose to the elastic band on the cloth cover. Doubles the collection compared to raking leave. It grinds up acorns and small twigs and shreds the leaves into a smaller more compact size creating more leaves per bag.

    Everything about it is great.


    Can't think of any cons.

    Great Product
    I am using this product for the second year now and it works great! I got the adapter kit with the unit and couldn't be happier. It makes cleaning up leaves a snap. Much better than the old unit I used to use..this unit has no problem with small sticks or clumps of leaves. The adapter allows me to put mulched leaves directly into large trash bags for pickup! I highly recommend this unit.

    Metal impeller. Adapter allows direct bagging of mulched leaves. High speed allows pickup of small sticks and clumps of leaves even if damp.


    Difficult to remove adapter hose connection to clear clogs.

    Very Nice Blower/Vac!
    Well I used both features on my Brother-in-law's lawn. He has a nice size yard with three huge oak trees and four or five medium maples. Needless to say, there were quite a lot of leaves. This blower/vac handled everything nicely. It definitely made the job easier.

    I love the leaf collection system for the trash can. It really does mulch the leaves well so you don't have to change out bags nearly as often. I thought the description was mostly marketing hype, but I vacuumed about 1/4 or so of the back yard and only had 1 1/2 bags of leaf mulch before quitting. I actually can't wait to get back out and finish the job!


    The only thing I can think of is that it needs a shoulder strap or harness to attach to the blower. I found myself stooping over quite a lot, making my lower back ache. I'm only 5'11", but maybe it was just the way I was holding it.

    excellent blowing & vacuuming, bag for vacuuming is not up to the task
    I have had this unit for a couple of years after getting frustrated with another unit that had a plastic impeller that kept jamming when I used it as a vacuum. The bag that captures the mulched material is not constructed of durable material and failed within the first year. I found a Worx brand large container adapter so I can use a 60 gallon trash cart as my receptacle however there are times when I want to use the bag that came with the unit. Black & Decker, use materials that are up to the task and last a reasonable time. This is not a difficult situation for your.

    metal impeller strong vacuum & blower force large vacuum tube minimizes clogs


    vacuum collection bag material wears out in less than one year! noise, though I understand you can't have the power without the noise.

    amazing vac very good blower
    First use was a shocker! The vac feature sucked up leaves so well it was almost scary at high speed and mulched very well (Not 16:1 prob 10/12:1). At low speed the mulching was not as good so I learned to operate it on high with the nozzle held up higher away from the leaves to keep it from sucking up dirt and stones. The blower met my expectations and suited my needs. I read the reviews about the substandard bag but I dont see a problem if care is taken when operating and emptying the bag.

    The vac operation and mulching


    The bag strap was not adjustable and made the bag somewhat awkward to carry during operation. The bag zipper seemed ok but did not unzip enough of the bag to make emptying as easy as it could be when overstuffed! :)

    you get what you pay for. a few more updates and it would be the best blower vac system ever.
    Packaging is great, metal blade out does my older unit. The larger vacuum tube is much better. As a blower, thr added horse power makes short work of the leaves. I have to use thr paper disposalbags for yard trash. I able to get 2.5 bag loads per each paper recycle bag. Good going B+D.

    The Metal Blade, and Added horse power. Larger vac tubes.


    The bag strap is too thin. and the connector on the bag is very tight to the motor housing.the old twist on would work better here.

    Product works well.
    Bought & used yesterday.

    The bagger option works very well.


    You need to have a fence stretcher to remove the blower assembly from the head in order to use the bagger. Secondly, the 240 MPH I feel is overstated. My old cheapy blower had more power, but, to be fair, I did not try the Leaf Blaster attachment.
