18V ONE+ HP 350 CFM Brushless Blower with 4Ah Battery and Charger
18V ONE+ HP 350 CFM Brushless Blower with 4Ah Battery and Charger is rated 4.8 out of 5 by 147.
Rated 5 out of 5 by from Really Blows I was tired of dragging out the 50' extension cord and my gas powered blower is getting difficult to start, so I purchased this blower mostly because it used the same battery as my trimmer. It wasn't the most powerful model available and it wasn't the cheapest. Middle of the road. I got it home, charged up the 4 amp hour battery and went to work on the patios and driveways around the property. I was pleasantly surprised! This thing really blows! It had more than enough power to move all the grass clippings and leaves from last year. Nice, compact design. Manageable weight. But it is LOUD. Hey, it's a blower. It's supposed to make some noise. Happy I bought it.

Rated 5 out of 5 by from Great blower! Lightweight & powerful! I ended up buying this model P21120 and I love it! I originally was looking to buy the P21110 based on the reviews. I went to the hardware store and they had several on display w/ batteries to test function. Glad I tested all of them!! The P21120 has plenty of power and brushless (less parts to malfunction). I have a desert landscape (lots of rock & bushes) and this blower handles leaves & debris perfectly! The lithium battery 4Ah works well. Lasts about 20 minutes w/ full charge on high. It feels good in your hand, easy trigger motion and well balanced.

Rated 5 out of 5 by from Light and powerful Bought it, unboxed it and put it to use. The 18V ONE+ HP 350 CFM Brushless Blower really blows ... almost too much. Great for big areas and patios. The wide nozzle helps cover a lot of area. I wanted to get leaves out of raised flower beds which it did, but you have to be careful around more delicate plants. A blower with a smaller longer nozzle and lower cfm would probably be easier to use. This blower eats up 1.5Ah batteries, so be sure to get at least the 4Ah battery. It is light enough to use one handed, so for my friends that carry a cold one while they do yard work, this blower is perfect.

Rated 5 out of 5 by from Great Power and battery I've bought into the 18V RYOBI tools, and they've all worked great. I added this one to my toolset as a gift over the holidays, and it holds true to the RYOBI brand. The blower works great, much more powerful than other battery ones I've used, and the 4Ah battery last a long time.

Rated 5 out of 5 by from Shorter, Stronger, Faster, Better! I had an old version of this blower and I dropped it, cracked it, broke it. Oops. But I used it for three years and took it as an opportunity to upgrade. Since I already had one battery I figured I may as well go with the same thing, but then I found this. And it's BETTER! It's shorter so it fits in a better place in my garage (where it won't fall like the last one, hopefully), and it's so much stronger. Everything gets blown away, and the battery lasts longer, too. My driveway holds about ten cars and I'm finally able to clear everything with just the one battery, but since I kept the other now I can blow away the back deck too! Thank you, Ryobi, for making your already-great products even better. This is NOT a paid or solicited review; I am a real person. My name is Mike.

Rated 3 out of 5 by from Type of Battery Issue Received for a Christmas gift. Good thing I have an arsenal of 18V One+ batteries on hand because the battery included in the box was an old (but new looking) orange and black standard 18V battery that would not even charge instead of a new 18V 4AH One+ battery. The box did not appear to have been tampered with. Love the blower and I am a real lover of the Ryobi line. I have countless Ryobi products and this is in fact be my 6th blower including a 40V. I will keep it rather than return to Home Depot due to store supply issues and the fact that I need the blower. By the way, I like the design of the rear air intake instead of the side intakes like the other blowers. Prevents tool from grabbing onto clothing.

Rated 5 out of 5 by from Good power, easy to use, good battery life! I bought this product to clear some of the leaves off of my porch and just to blow them into a pile, and it worked so well. The battery life of the blower is good, and it lasted me a good amount of time. The power of the blower is pretty great because it was able to get the job done, and still move around some of the smaller rocks on my sidewalk. The charger works very quickly, and in all this product is rea[lly easy to use!

Rated 5 out of 5 by from Great for my Backyard/Patio Been looking for a Blower. I have a large maple tree in my yard and it dumps a ton of leaves. Add that to the messy eater birds (5 feeders), a family of squirrels and the Santa Ana winds and at times I have to blow my yard/patio off a couple times a week. So nice not to have to drag a corded unit around anymore. If I was to fix one thing, is make it longer. I am over 6 feet tall and the unit is one the shorter side.
