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.

ATTENTION: The motor housing under the body of the tool is the air intake for the Worx AIR Cordless Leaf Blower / Sweeper.

Rated 5 out of 5 by from Very good battery operated blower I've had this blower for several weeks and am very pleased with it. I did upgrade to the 4.0 Ahr battery which I think may be the key. Obviously the force from the blower is not as powerful as a gas operated blower but it is good. I've used it to blow leaves in the yard and then pine straw from my older home that I'm selling. The run time from the 4.0 Ahr batter is good. I'm glad I did purchase this blower with the 4.0 Ahr better and did get a second battery so I could have one ready when the first was used up on projects. So far I have not use any of the handy attachments that came with the unit but a lot of "thought" went into the design and they will be handy.

Rated 5 out of 5 by from Great Blower ! I purchased this blower mainly for my wife due to it be light weight and portable. I took advantage of the special one day Fathers Day buy and have no regrets. I was worried about the battery life but surprised after 15 minutes of use I still have two of three lights lit. Basically, I've used it more than my wife as I enjoy using this blower which has plenty of power to clean my driveway etc. after mowing. The battery charges fast and overall I'm well pleased with the purchase!

Rated 5 out of 5 by from Definitely does the job! I received this as a gift and have used it to remove grass clippings and debris from my driveway and sidewalks after mowing. It works great! The battery charge was enough to get the entire job done and the blower is very lightweight. I'm sure it will be very useful when the leaves start dropping this fall.

Rated 5 out of 5 by from Still a great tool. I bought this to replace one that was many years old but was recently stolen from my yard or garage. The new one is more powerful and works exceptionally well to clean up the sidewalk after edging and mowing. I live on a corner so I have 150 ft of sidewalk. Being light weight and no cord it is very easy for an older person to use.

Rated 5 out of 5 by from Light weight and easy touse, stays charged I bought my blower three years ago and have loved using it. My 88 year old father just had his shoulder replaced and was so impressed with how lite weight the blower is he hinted that he wanted one for Fathers day. He has been thrilled with what the blower can do! He will never drag a electrical cord around again nor will he pull on a cord to start his gas blower!

Rated 5 out of 5 by from No more back aches!! My old messy gas powered blower began leaking last summer, so I had to start using a broom to sweep up every time I mowed. The sweeping motion really irritated my back. I used the broom once this season and was done! It was time for a new blower and I wanted something easy and lightweight. The Worx Cordless Leaf Blower is FANTASTIC!! This blower is so much easier than my old gas powered one and lighter! I can get the job done without the aches and pains of using a broom! And it's one needs to be in the Texas heat any longer than necessary! After using this just once, I was sold on the Worx products and have ordered the cordless trimmer/edger. Can't wait to receive it!

Rated 5 out of 5 by from You’ve got to be kidding me! It’s unfortunate I didn’t know about his blower sooner. The gas blower I used for more than 20 years, along with its cumbersome choke start and need for mixed gasoline, has been banished to the dusty corners of my garden shed as the back-up tool. I bought the extra battery pack which I highly suggest other customers to purchase. When the battery needs recharging, it’s an abrupt end to blowing. The 2nd battery pack has saved me a few times. You won’t see me pulling out the gas-blower again. This tool is a must-have!
