I bought this model to replace an older B&D blower that started making rattling noises. I use these blowers to clean up my sidewalk and driveway after mowing the lawn (bagless) and they work just fine. I thought the boost button would be a nice addition for those wet clumps of grass that the blower usually can't push. Unfortunately, it seems the boost button just brings the fan up to the level of the single speed of the previous model. So, I find myself mostly holding down the boost anyway.

Handy for light jobs
This Black & Decker blower is lightweight and easy to use. This blower works great in the garage and on patios for blowing dry and leaves leaves and debris away. It's not powerful enough for removing wet or caked on material from driveways or sidewalks. But it does work well for dry loose material. So it is great for garages and patios in small areas. To remove leaves and other debris from lawns or flowerbeds this would not work well. But it is a handy blower.

My kind of Blower!!
I bought this Blower/Sweeper because I had purchased the 20V Max Lithium Smart sense Trimmer and they use the same 20V Max Lithium batteries. I wanted a Blower/Sweeper that was lightweight and cordless and this item fit the bill perfectly!! Did I say it was powerful and battery was long lasting?! The PowerBoost feature is another added feature I love for extra boost. Thank you B&D for creating products that use the same type of power source - it makes my life so much easier.

I have an electric leaf blower (B&D) for big jobs, but it was a pain to pull it out for a quick clean up of deck or driveway and of course there were places out of reach of the power cord. This little blower works great! I've used it several times without running out of battery power, although I haven't used the powerboost much. Very satisfied customer.

The instructions say the battery needs to be be charged but it doesn't tell me how to charge it. How do you charge it?
