Convenience + Performance
I recently got my hands on one of these and it's now in daily use. It offers comparable performance to gas blowers with a ton more convenience.

Powerful enough to clear debris from smooth surfaces as well as grass.

Quieter than most of the gas models. Also, it doesn't need to idle like gas models so it is silent when not in use.

Great trigger feel and responsiveness with a nice lock that can maintain any throttle setting

No emission – no need to close all the windows when you fire this up

It runs cooler than gas models

Low vibration – no internal combustion engine = less vibration

More to come – The 40V DeWalt line will surely expand offering a ton of great tools and equipment

No need for gas

Good run time. I cleaned up my entire yard (about 30 minute of use) on one charge. I haven't checked to see how long it can run continuously but it was more than enough for my 1/2 acre lot.

It's not as powerful as the mid 20 cc gas models. This delivers about 10% less CFM at 400 vs. 440 from most gas models. It's still quite powerful, but you'll be taking a hit during max output.

Cannot imagine a better blower.
This blower is the bomb! Of all the lawn equipment products I have purchased of late, this is hands down my favorite. I do my own yard work which includes mowing and edging the grass, trimming hedges and blowing loads and loads of ficus leaves from under a monster size ficus tree. This blower has the power to do it all with ease and the charge time to finish both the front and backyard in one charge. Love the variable speed, the ability to set a level of power and yet still increase on demand, the charge time left display and the quick re-charge time. I cannot think of one negative. The only thing to be aware of is if you switch to your left hand, you need to keep the blower away from your leg as the fan that sucks in the air is on the right side of the blower. A great, great product!

Very powerful
Very powerful and easier to use than my gas powered unit
Just snap in the battery and your are ready to go
After 1 1/2 hours of running The battery still had 1/3 of the power remaining.
Easily handles leaves and grass clippings and is great for blowing out the gutters

Dewalt Blower 40V
I was a little concerned the power would not be enough to blow with leaves but it has definitely lived up to my expectations. It's nice to have a cordless option that instantly works. Not to mention it is fun to chase my 2 year old around the yard.

Easy To Use
Typical DeWalt High Quality design and functionality. Very powerful and easy to use.
Good run-time on the 4 amp/hr battery. I have the DeWalt Weed Whip with the 6 amp/hr
battery, so I have a back up battery. The larger capacity battery is better but it prices the blower
much higher so I opted for the smaller capacity battery. I can do my large property (with lots
of plantings and beds) completely, 2 times on a single charge. No more messing around with,
and storing, fuel. Very Pleased! I would absolutely recommend it!

Dewalt 40v Blower
So far this has been a great product. I wish it came with diifferent attachments for the end to help direct the air. Nothing a little rigging can't fix. Overall the power and performance is comparable to a plug and unit I used to have. Battery life is enough to get most small jobs done

Not as powerful as gas backpack, but easier to use for medium to small jobs. Very adequate volume and speed of air for a battery device. Love the freedom the cordless feature gives you. Pick it up and go!!

Blow-Out or Not
Charge the battery, and this works right out of the box. I use it to clean up the garage floor, patio and walkways and enjoy its performance. Great tool to own.

Does this blower have a thermal overload shut off on it?
I just got this blower and after about 5 mins of use it shuts off.
Bob on Apr 14, 2016
BEST ANSWER: Don't know about the thermal cutoff. Mine has never shut off on me. Make sure your battery or charger aren't bad--batteries especially I've heard can be duds.

how does this unit compare in blowing power to the gas powered units? how long - number of minutes, will the blower battery last?
No nickname. Name is Ted on Sep 25, 2015
BEST ANSWER: I sold my Echo backpack blower because this cordless has almost the same CFM. Now I use it 10 times more than the gas ones because I don't have to check the fuel, (mix gas and oil if low), prime it, choke it, start it, let it warm up then use it. With the cordless DeWalt you just pull the trigger! So it gets used way more, great for cleaning off sawdust in the shop because your not running a gas engine inside. I mainly use it for leaves and blowing grass off the driveway after mowing. Also clean off the 4 wheeler, lawnmower, pollen off of vehicles etc. Im very happy with the unit, the other thing is I had a hand held gas blower but my hand would go numb because of the vibration of the gas engine and it could also burn your leg if you weren't careful. My wife and kids use this to and don't have to worry about them using the wrong gas or not getting it started!
Does this model (40V Cordless Blower) come with other attachments - i.e. hedge clippers?
If not does Dewalt have dual purpose - battery powered - lawn tools?
None on Aug 2, 2015
BEST ANSWER: No, the blower does not come with any attachments. However, Dewalt DCHT860M1 is the model number for a hedge trimmer that operates on the same 40V system.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
