Frequently Asked Questions

How heavy is the 20V AIR Cordless Leaf Blower / Sweeper?

The great news is that it’s not heavy! The Worx AIR Cordless Leaf Blower / Sweeper only weighs 4.3lbs. With our ergonomic design to ensure even this small amount of weight is optimally distributed, clean-up has never been so effortless, comfortable or so portable!

Is the Worx AIR Cordless Leaf Blower / Sweeper electric or battery operated?

Worx has an entire family of products, some of which are battery operated and some of which are electric. The WG545.4 is a battery-powered model and uses a 4.0Ah 20V Worx battery.

How long can you use the Worx AIR Cordless Leaf Blower / Sweeper on each 20 Volt Max Lithium battery charge?

Runtime will vary from job to job, and sometimes between users, depending on how each person works. The battery included with your Worx AIR Cordless Leaf Blower / Sweeper will take you far, but remember you can also use any 20V Worx batteries you already have so you’ll never be out of power.

Is the battery larger than previous models?

The Worx AIR Cordless Leaf Blower / Sweeper features our highest capacity battery to date. The included 20 Volt Max Lithium Battery has an amp hour rating of 4.0 compared to our previous 2.0 Ah models. The amp hour rating measures how much energy can be stored in the battery (energy capacity). The Worx 20V Max Lithium 4.0Ah battery can hold almost twice the amount of energy as previous models in the same size battery due to advanced battery chemistry. This means it will have up to double the run time of the 2.0 Ah 20V battery.

I already have some 20V Worx batteries, will they work in this tool?

Yes! Powershare lets you share batteries and save money. Any 20V Worx battery you already own will be compatible with this tool, and the batteries included in this package will work on the 20V Worx tools you already have.

Is the battery going to be powerful enough?

The lithium battery powering our cordless Worx AIR Cordless Leaf Blower / Sweeper is powerful to drill through concrete and large timber, so they’re definitely powerful enough for clean-up to give your lawn the professionally manicured look you’ve always wanted.

What’s the difference between the WG545.4 and the previous WG545.1?

The difference between the two model numbers is the battery. The WG545.4 features a 4.0Ah battery where the WG545.1 features a 2.0Ah battery. This means the WG545.4 will have up to double the run time of the 2.0 Ah 20V battery, model WG545.1.

Does this use the same batteries as my other 20V Worx tools?

Yes! With Power Share, you can share the battery and save money. Your Worx AIR Cordless Leaf Blower / Sweeper can use any 20V Worx battery you already have. By sharing the battery between tools, you’ll always have the power you need to complete any job.

What is the horsepower rating of Worx lithium tools?

Battery powered DC motors are not rated for horsepower as output power is only measured with gas or induction AC (corded) motors. Worx lithium-powered products are designed with sufficient power to get the job done quickly & easily.

How long does it take to charge the 20 Volt Max battery?

It takes approximately 2 hours to fully charge the battery using the charger that comes with model WG545.5.

Are lithium batteries interchangeable with the Ni-Cad?

Our lithium tools and Ni-Cd tools are separate platforms and are not interchangeable. Lithium batteries offer our customers maintenance-free technology without the hassle of managing the memory effect inherent in Ni-Cad batteries.

Are the 20 Volt Max Lithium batteries interchangeable with the 32 Volt Max Lithium Battery?

While Power Share allows you to share batteries between tools within the same voltage family, batteries can only be used with tools of a corresponding voltage. Use your 20V Max Lithium battery with any 20V Worx tool – even the power tools – but save your 32V battery for your 32V tools.

What is the horsepower rating of the Worx AIR Cordless Leaf Blower / Sweeper? How powerful is it?

Horsepower rating is more accurately used to describe gas-powered tools. The Worx WG545.4 AIR Cordless Leaf Blower / Sweeper is powered by a 20V battery with a 4.0 Amp hour rating, which measures how much energy can be stored in the battery (energy capacity). This is twice as much capacity as our previous 20V batteries without increasing the size, an expansion achieved through advanced battery chemistry. You can depend on the power they provide. With an airspeed of 120mph, you can be sure the Worx AIR has the power to get the job done, whether cleaning up lawn trimmings or sweeping leaves off the front porch.

Is this also a vacuum like some of the other electric blowers Worx offers?

The WG545.4 does not include a vacuum feature. For a complete 3-in-1 electric leaf blower/vacuum/mulcher, check out the Worx TRIVAC or the TURBINE FUSION.

Is the Worx AIR Cordless Leaf Blower / Sweeper variable speed? How do I change the speed?

The WG545.4 Worx AIR is not a variable speed blower. If you’re interested in having more control over the air flow or speed, check out our Turbine family of blowers.

Does it come pre-assembled?

Each Worx AIR Cordless Leaf Blower / Sweeper comes with some minor assembly required, but it will take less than 3 minutes and will not require tools.

Once I put the AIR together, can I disassemble it?

Yes, you can disassemble the AIR after you’ve put it together. We make it convenient to easily switch out the accessories to meet the needs of each job. Locate the textured circle on top of the Worx AIR long tube. Press it and pull the tube away from the body of the Worx AIR. To install other accessories, line up the textured circle on the Worx AIR with the corresponding hole on the accessory and push them together until they click.

Are there any precautions I should follow when using the blower with damp leaves? Will I get shocked?

Regardless of the tool or job at hand, we recommend that our customers follow standard safety precautions while using our tools, including wearing safety eyewear, gloves, appropriate shoes and clothing, and keeping hair tied back. Always refer to the owner’s manual for complete safety information before operating any tool.

AIR Cordless Leaf Blower / Sweeper Hi-Capacity (4.0 Ah) is rated 4.7 out of 5 by 231.
Rated 5 out of 5 by from Easy to Use Purchased about a month ago. Don't know how I got by without it. After mowing, i use it to clear the driveway and stone patio in a fraction of the time I spent using a broom. Now I am blowing leaves off the front and back porches. So lightweight my wife loves using it too.

Rated 5 out of 5 by from Everything I wanted! It's that time again! Fall for me is about 4 weeks of non-stop work in a battle against the falling leaves from the 20+ 80' oak trees in my yard. I tried blowing them in the past, but what a pain dragging the extension cord out and dragging it behind me as I pushed the leaves all over the yard, and then the put away work was tedious too. I'm 70 and I just don't need that anymore. I just got in from clearing leaves from my deck, porch, and driveway, only now I have my new WORX Cordless Leaf Blower to help with my chore! No more set up work, no cords, nothing to it now, just put the battery in and get going. My deck is about 600'sq and my porch is another 300"sq so we are talking a lot of area here. No problem today! No moving the cord from the back to the front outlet, no reeling up and storing the cord either - just put the battery in the charger and go watch the football games. OOPS! Almost forgot, I bought a second battery and while charging the one I just used, my son and I cleared the leaves from the back yard. I think he is just finishing reeling the cord from that "other" leaf blower while I watched our games. Thanks WORX for a light weight, powerful tool that is most awesome! Oh yeah, I am going to use that 10% WORX coupon to buy the vac, my son could use a better tool too!

Rated 5 out of 5 by from Perfect for my Needs! Needed a lightweight leafblower that had enough power to blow leaves and small groundcover bark off my driveway. This one is it! Output air is finely focussed, so you can precisely control it: light for leaves and heavy for the bark. Battery lasted forever, it seemed. Very light weight, easy to carry and control. A Winner!

Rated 5 out of 5 by from Pleasantly surprised Bought this when I ordered the string trimmer thinking it would be a light weight blower that I may find handy to clear the decks and the garages. Light weight... it truly is. Handy... absolutely. This blower has now found itself part of my frequently used tools to keep our garages and decks looking spiffy!

Rated 5 out of 5 by from Excellent Tool To Add to Your Collection I purchased this Cordless Leaf Blower to make my job easier instead of sweeping up the grass clipping whenever I cut my lawn and also for the debris that washes down my sidewalks whenever it pours down raining. This Cordless leaf blower/sweeper saves me immense time and body work by merely blowing the clippings and debris to a centralized point where I can easily pick it up for the garbage. It sure beats sweeping as it difficult enough to cut my grass let alone to sweep up the trimmings left in the street after cutting grass. My wife can also use this tool which she enjoys as it is so easy to use. We both are glad we made the decision to purchase this Cordless Leaf Blower.

My leaf blower is not working correctly.  I am putting freshly charged batteries in and turning it on. It will run for 10 minutesor so and then go off.  The same battery will run my trimmer/edger for at least 30- 45 minutes so I don’t think that is it.

Asked by: The Mic

Asked by: TeriB

I purchased the Worx WG545.4 Air Cordless Leaf Blower HiCapacity (4.0AH) and found it to be blowing at a " LIGHTWEIGHT" removal of grass clippings and debris. I am returning this unit for the WG591 Turbine56V UNIT. Will the WG591 deliver the POWER ?

Asked by: Walt 47
Thank you for your question. We apologize that the WG545.4 did not meet your expectations. The WG591 Worx Turbine 56V Cordless Blower is effective because the TURBINE fan technology delivers forceful, high-capacity air volume and has a variable speed control setting that includes TURBO boost.
