In my pursuit of the perfect lawn, I’ve had my fair share of encounters with lawnmowers, from the clunky gas-powered behemoths to the corded electric models that often left me tethered to an extension cord. 

Recently, I had the opportunity to test out the Worx WG779 Cordless Mower, and I must say, it left a lasting impression. In this comprehensive review, I’ll delve into the features and performance of the WG779, offering insights from years of testing different models.

Overview of Worx WG779’s Specifications

What's in the Box

Features of the Worx WG779

Blade Length and Cutting Power

The Worx WG779 boasts a 14-inch cutting blade, which strikes an excellent balance between coverage and precision. This cutting width is perfect for smaller to medium-sized lawns, providing efficient mowing without sacrificing maneuverability. 

The metal blades ensure durability and a clean, precise cut, far superior to plastic alternatives that tend to wear down quickly.

Intellicut Technology

One standout feature of the WG779 is its Intellicut technology. This system automatically adjusts the mower’s torque based on the grass conditions [1]. When faced with thick or challenging grass, the Intellicut feature steps up to provide extra torque, ensuring a smooth and efficient cut. 

On the flip side, during lighter mowing conditions, it conserves energy, extending the battery life. This intelligent system enhances both performance and efficiency.

Battery Powershare

The Worx WG779 is part of the Powershare family, meaning its battery works with all Worx 20V and 40V power tools. This compatibility is a significant advantage, as it eliminates the need to invest in various batteries for various tools. 

With the inclusion of two 20V 4.0Ah Lithium-ion batteries, you’ll have ample power to tackle your lawn. 

The smart dual-port charger provided with the mower ensures both batteries can be fully charged in just two hours, offering up to 40 minutes of runtime in ECO mode – a commendable duration in its class.

The added benefit of a ‘smart’ charger is that it prevents overcharging, safeguarding the battery’s health and safety. When a battery is done charging, the charger automatically stops, reducing the risk of overheating or other potential issues.

Indicators for Precision

Maintaining control and precision is crucial when mowing your lawn, and the WG779 excels in this aspect. It features a battery charge indicator that allows you to monitor the remaining power easily. 

Additionally, the batteries themselves have power indicators, eliminating any guesswork. The grass collection bag also sports an indicator to alert you when it’s full. With an ample 0.85 bushel (approximately 30 liters) capacity, it’s suitable for a mower of this size.

Handling and Storage

One of the immediate advantages of the Worx WG779 is its lightweight design. Traditional gas-powered mowers can be notoriously heavy, but this model’s use of lightweight yet durable plastic instead of a heavy metal deck makes it a breeze to maneuver. 

The padded handles provide a comfortable grip and enhanced control, which is particularly helpful in preventing users from sliding during operation.

Storage is another area where the WG779 excels. After folding up the handlebars, it can be conveniently placed on a shelf. Since this mower doesn’t rely on petrol or oil, you have the flexibility to store it at any angle.

Noise Level

If you’ve ever been bothered by the deafening roar of a gas-powered mower, you’ll appreciate the relatively quiet operation of the Worx WG779

Cordless mowers, in general, produce about less noise than their gas-powered counterparts, making them a more neighbor-friendly choice. 

You can further control the noise by selecting the ‘ECO’ mode instead of ‘TURBO,’ though ‘ECO’ mode is not recommended for cutting long or dense grass.


The Worx WG779’s metal blades and precise design allow it to cut near the edge of your lawn. For most yards, you won’t need additional tools like an edge cutter or a weed whacker. 

However, it’s worth noting that this mower isn’t ideal for tackling long or wet grass. Mowing under such conditions can significantly reduce battery runtime, so it’s best suited for maintaining well-manicured lawns.

With a cutting width of 13 inches, the WG779 is tailored for smaller yards. However, if you have a wider lawn to tend to, exceeding the size of two tennis courts, you may want to consider a mower with a wider cutting width, such as larger cordless models offering a 25-inch width.


Safety is paramount when operating any equipment, and the Worx WG779 incorporates unique safety features. It includes a key that must be plugged in order for the mower to fully activate. 

This key is securely attached to the mower with a cord, preventing it from getting lost. This safety measure ensures that the mower cannot be accidentally started, which is especially valuable if you have children around.

Pros of the Worx WG779 Cordless Mower

Compact and Lightweight Design

I absolutely love the compact and lightweight design of the Worx WG779. It’s a breeze to maneuver, even in tight corners, and storing it is a snap. The ease of handling makes the mowing process much more enjoyable.

Quiet Operation

Compared to the thunderous noise of gas-powered mowers, the WG779’s relatively quiet operation is a game-changer. 

It’s a pleasant surprise that allows me to maintain my lawn without causing a disturbance to my neighbors or disrupting the peace and quiet of my surroundings.

Battery Compatibility and Smart Charger

The inclusion of two 20V 4.0Ah Power Share batteries and a smart dual-port charger is a standout feature. 

Not only do I appreciate the versatility of these batteries, which can be used with other Worx 20V and 40V power tools, but the smart charger’s ability to prevent overcharging adds convenience and peace of mind to my battery maintenance routine.

Intellicut Technology

The Intellicut feature, which automatically adjusts torque based on grass conditions, is a real game-changer. It optimizes cutting efficiency, allowing me to tackle thicker grass without slowing down while conserving battery life during lighter mowing tasks.

Clean and Precise Cutting

The metal blades and precision cutting deck design deliver a clean and precise cut. I don’t need to worry about going back to trim the edges because the WG779 mows close to the edge, eliminating the need for additional tools. 

The durability of the metal blades is also a big plus, ensuring a longer-lasting cutting solution compared to plastic alternatives.

Safety Features

I greatly appreciate the safety features of the WG779. The key-based power activation and attached cord add an extra layer of security, ensuring that the mower cannot be accidentally started, especially when my children are around.

Eco-Friendly and Maintenance-Free

Being eco-friendly is important to me, and the WG779 fits the bill as it operates without the need for gasoline or oil. Plus, its minimal maintenance requirements save me time and effort, allowing me to focus on enjoying my well-maintained lawn.

Cons of the Worx WG779 Cordless Mower

Limited Cutting Width for Larger Lawns

While the WG779 is perfect for smaller to medium-sized lawns, its 13-inch cutting width can be limiting for those with larger properties. I’ve noticed that it takes longer to cover my entire lawn due to the narrower cutting path, which can be a bit frustrating.

Not Ideal for Tall or Wet Grass

Dealing with tall or wet grass can be a challenge for the WG779. It struggles under these conditions, and I often find myself making multiple passes to achieve the desired cut. 

This limitation can be a bit of a letdown when tackling overgrown or challenging grass.

Runtime May Not Be Sufficient

While the WG779 offers a runtime of up to 40 minutes in ECO mode, I’ve found that this may not be enough for larger lawns or extensive mowing tasks. Recharging the batteries can interrupt the mowing process, extending the overall time spent on the task.

Mulching Option Can Clog

While the mulching option is a great addition, I’ve encountered issues with clogging when using this function. Clearing the clogged chute manually can be a hassle and adds extra time and effort to the mowing process.

Not Ideal for Rough Terrain

I’ve noticed that the WG779 is best suited for relatively flat and even terrain. When faced with rough or uneven lawns, its performance can suffer, leading to uneven cuts or difficulty maneuvering over bumps and obstacles.

Review Conclusion: Worx WG779

As someone with extensive experience in lawn care, I can confidently recommend the Worx WG779 Cordless Mower to anyone seeking a dependable and user-friendly solution for their lawn maintenance needs. 

With its exceptional features and Worx’s reputation for quality, it’s a mower that will help you achieve a perfectly manicured lawn without the hassle of cords or the noise of gas engines.
