Overall, the DEWALT DCBL790M1 finished just behind the top group of products, leaving it without an award. It failed to impress in our most significant metrics — power and battery life — significantly holding it back. While it is one of the easiest and least fatiguing cordless blowers to use and one of the quietest, it is priced comparably to the top products, making it quite hard to recommend.

|Cons||Expensive, so-so power, mediocre battery life||Could be a bit more ergonomic, quieter||Unimpressive battery life, so-so ergonomics and comfort||Moderate battery life, has a high-pitched undertone||Not the most powerful, can be earsplitting to operate|
|Bottom Line||The DCBL790M1 is priced like a top-tier model but couldn’t really compare to their performance in our tests||If you want the best you can get when it comes to cordless leaf blowers, we highly recommend the Ego Power+ 580 CFM||The XBUO2PT1 is a solid blower on its own merits and has interchangeable batteries with handheld Makita power tools||If you want a powerful leaf blower that isn’t going to blow your budget, you should snap up the Snapper 82-Volt Max||If you are a budget-conscious shopper looking for a new leaf blower, we highly recommend the Ryobi|

Our Analysis and Test Results
The DCBL790M1 finished just behind the Snapper 82-Volt Max and ahead of the Ryobi RY40460. Both of these blowers are quite a bit less expensive and more powerful, with all three having similar battery performances. The DEWALT is more ergonomic and quieter but its significant price increase over the other two makes both the Snapper and the Ryobi much better bargain buys.
To pick out which cordless leaf blowers we were willing to bestow awards upon, we first bought all the most promising models currently on the market and tested them head-to-head. We grouped our tests into four weighted categories, with the DCBL790M1's performance in each test explained in the sections below.
Comprising a whopping 50% of the final score for the DEWALT, our trio of blower strength tests are our most important assessments. We measured the height the DCBL790M1 could levitate a beach ball, its maximum range at moving sand, and its overall effectiveness at clearing different types of rubbish. As mentioned above, we weren't particularly impressed with this cordless blower's performance, awarding it a 5 out of 10 when it came to power.
Floating the inflated beach ball to a height of around 4' or so, the DEWALT did fairly well compared to the other products in this test.
It also didn't have a particularly impressive range, with this blower only able to clear sand up to just shy of 11' (129 inches) from the nozzle — quite a bit less than the almost 20' of the top blowers.
The DCBL790M1 is relatively average when it comes to clearing mixed debris. We set to work clearing some of our parking areas with the DEWALT, which was covered in leaves, lawn clippings, dirt, sand, and small pebbles. It can move the lighter items a fair distance but we still had to do quite a bit more walking compared to the best models. It also totally struggled with larger pebbles or when the pine needles clumped together, only really able to move them at point-blank range.
Our second group of tests dealt with the battery life and recharge time of the DEWALT. This accounts for 25% of its total score, with this blower delivering another lackluster set of results, earning it a 5 out of 10.
The DCBL790M1 runs on a nominal 40-volt battery system and includes a single 4 amp hour battery. For this test, we started this cordless leaf blower with a fully charged battery, then timed how long it lasted.
Unfortunately, this blower didn't have the most impressive battery life, only lasting for 17 minutes and 44 seconds, which is less than half of the operating time that the top products had. For our second assessment of this metric, we timed how long it took to recharge a totally dead battery with the included charger.
The DEWALT did charge a bit faster than average, only taking an hour and 26 minutes or so in our test.
Next, we rated and compared the ergonomics and ease of use for each cordless leaf blower, which is responsible for 15% of the final score for the DCBL790M1. It did quite a bit better in this metric, earning an 8 out of 10. This was based on the DEWALT's weight, its balance and grip, ease of access to its controls, and where its air intake is.
The DCBL790M1 is a bit on the larger and heavier side, weighing in at almost ten and a half pounds with its battery installed.
However, the DEWALT is almost perfectly balanced, maintaining an essentially ideal blowing angle with no effort at all on your part. The grip is fine to hold but is a bit on the larger side, so could be a bit more difficult to hold for those with more petite hands.
The intake is on the right side of this blower, which can be a bit frustrating if you use it in your left hand, as it will occasionally try and suck in your pants if they are on the baggier side.
This cordless blower does have cruise control settings and a trigger interface.
Our final metric focused on the noise level produced by the DCBL790M1, which constitutes the remaining 10% of its total score. We measured both the sound level for the user with the blower on its most powerful setting and the noise for someone standing 50' away. The DCBL790M1 again did quite well, meriting an 8 out of 10.
The DEWALT generates about 90 dBa of noise for the user, which isn't necessarily the quietest model we have seen. However, our judges liked that the tone of the DCBL790M1 is super mellow and it lacks a high-pitched whine that many other blowers had.
The sound does attenuate a bit at some distance away, only causing 82.9 dBa for a bystander 50' away.
Regrettably, the DEWALT is a terribly value, having a price tag that is comparable to the top models but finishing in the middle of the group overall.
The DEWALT is a decent cordless leaf blower but we are a bit reticent to recommend it due to its relatively weak performance in our power and battery metrics.
