This DeWALT blower fit my needs perfectly. I was so tired of carrying around our electric blower and its massive tangle of extension cords. It is so light and easy to hold you can blow with one hand and move furniture with the other. I can't speak to how long the battery lasts, only to say that I am able to blow my front porch, large courtyard area and walkways and the inside of my house, at least twice before a charge. I just throw it on the charger at that point because I don't want to run out of juice half-way through a job.
Being able to control the exact speed of the blower with your thumb while blowing is perfection. I can use a light setting to blow leaves, dirt and dog hair and increase speed to move heavier loads of dirt and debris. The battery is easy to remove and placement in the bottom within a stand is really handy. It takes about 1/4 of the space of our electric blower.
But what really blew me away, was the discovery of how much time it would save me inside my house. Since it was raining when I received the blower, which was my Valentines Day gift. I turned it on inside to try it out. Now I use it several times a week to blow the dog hair, dust, dirt and dog hair off my hardwood floors. Of course it doesn't work on chunky rugs or carpet, but it does get the dog hair, dirt, food and dog hair off the sofas too! Where this blower really shines is on the stairs. I used to just ignore my stairs between cleanings rather than drag my vacuum around or fumble with attachments. Now I can blow about 2000 sq ft of hardwoods, including stairs, flat rugs and furniture in about 7 minutes versus a good 20 with the vacuum. Sometimes I blow it all right out the door and keep going and sometimes I blow it all into a pile that I pick up with our quick pick up vacuum.
I attempted a video of this feat, but it is not easy to do. However the fact that I can hold my phone and blow my floors at the same time is a testament to how light and easy to use this blower is!
