In Brief: Worx Wg779 Lawn Mower Review

Worx WG779 is a cordless, highly efficient battery-powered lawn mower that features a deck of 14 inches. With two 20V 4.Ah batteries, it has plenty of torque to fulfill medium-sized lawn needs. More specifically, it is ideal for a maximum of 5,500 square feet lawn with one single charge, approximately one-eighth of an acre. Furthermore, it comes with the impressive ability to mulch the lawn or, alternatively, to collect the cuttings in a bag of 8 gallons.

Worx is a company that offers high-quality garden and lawn equipment, power tools, and other accessories. The brand offers its buyers a wide array of products, but it is best known for its range of lawnmowers and chainsaws.

Furthermore, their products distinguish themselves by having zero carbon emissions, as they run exclusively on batteries, thus protecting the environment.

The WG779 is a top choice when it comes to other lawn mowers in its league. It has a lightweight design that comes with impressive power for such a small, compact mower. This is perhaps the best lawn mower for yards under 5,500 ft.

Unique Features

The WG779 is a worthy choice due to several reasons, but we are going to present two that make it stand out from the crowd.

Battery Technology

Worx is well-known for its environmentally-friendly products that have zero carbon emissions.

This means that their battery-powered products also feature cutting edge battery technology that offers them high value for money and the required torque to perform any task.

This is possible by using the high-quality, durable pair of 20V Worx batteries that can be swapped with other 20V batteries from other power tools in the same line.

Port Charger

Furthermore, the WG779 features a port charger. This is important because it means that you do not need to take the batteries out every time you have to charge them, which might be cumbersome and even annoying.

All you need to do is plug the port in a socket, and it starts charging.

Furthermore, the battery technology used by Worx comes with a smart charger. You should know that this is a serious issue if you are not familiar with the dangers of overcharging batteries.


Power, Design, And Durability


The power of WG779 comes from its two cutting-edge batteries of 20V each. This ensures the power needed to perfectly manicure any lawn of up to 5,500 square feet. The batteries take approximately 4 hours for a full charge.

Furthermore, the product has an eco mode that can be used for lighter cuts, thus reducing the power needed. This can extend the cutting time.

However, this mode comes in handy if the lawn has been recently trimmed and does not require much power, unlike longer grass that can be cut with the turbo mode. The eco setting extends the mowing time by reducing power.


The design of this electric lawn mower is based on durability and convenience. It is lightweight; thus, you can easily cut around landscaping items, such as trees, or close to the edges.

The build of the lawnmower is also extremely stable, offering comfort and peace of mind when using it.


The durability of the product is undoubtedly not questionable. Worx uses only premium quality materials to design its power tools and equipment.

The lawnmower can last up to 50 minutes when mowing, which might not be a very long time. The eco mode can extend this time, but the turbo mode makes mowing a very quick task.

Cut Quality And Available Options

Given the light weight of the product, we can easily conclude that it is very nimble when in use. If you have a very large yard or wide-open spaces, you might find it quite small for your needs.

The cut quality is as expected, living up to Worx’s well-known standards. This lawnmower can do a beautiful job due to its maneuverability if you have many landscaping features, such as trees and contoured edges.

You can easily change the height due to the mower deck of 14 inches in terms of cutting options. All you need to do is use the single lever switch to adjust between the sizes: 2 inches, 3 inches, or 3.5 inches.

Performance And Ease Of Use

The performance of the Worx WG779 is flawless when used on small to medium-sized lawns. You can use it up to 50 minutes on a turbo mode, ensuring a quick manicure of your lawn.

You can quickly get to work, since the battery-powered system means that all you have to do is turn it on and start mowing, as long as it is charged.

When it comes to using it, the lightweight design makes it convenient and quick. You can turn around with ease, helping you to trim each landscape feature comfortably.

Furthermore, the single-lever switch that changes the cutting height requires only one push or pull to adjust all four wheels at once. This means that you can easily adjust them, unlike other mechanisms that change only one wheel at a time.


Ease Of Maintenance, Repairs, And Warranty

Similar to other products in this category, the WG779 needs blade sharpening and maintenance when you use it during the season.

It is best to check it out in the spring, and if you notice any problem, you might want to take it to a professional to sharpen it.

If it is damaged or very dull, it might not have the same performance: it could increase the cutting time, or eat through the power.

If you prefer to bag your clippings, make sure you empty the bag properly after each session. Otherwise, the small bits decompose very quickly and might be difficult to clear away.

The port charger will help you maintain the battery power with ease, without having to unplug it or monitor it all the time.

However, during cold weather, it is best to take the batteries out and keep them inside, since low temperatures can limit the battery life.

When the lawnmower is not in frequent use, such as during the winter, it’s best to charge the batteries every month.


Worx offers two years of warranty for most of its equipment, including the WG779. You can, however, extend the warranty to 3 years.  All you need to do is register your product online within 30 days of purchase.

The batteries have a 1-year limited warranty that cannot be extended.

Price Of Worx Wg779 14

The price of Worx WG779 is surely worth it. One significant aspect that offers high value for money and cost-effectiveness is the innovative battery technology.

For instance, the charging port and the smart charge will help extend the battery life, preventing damage.

Furthermore, if you have other Worx tools, you can swap the batteries at any time, or you could use these batteries to power other equipment.


Who Should Buy It?

The lightweight, user-friendly Worx WG799 is ideal for lawns up to 5,500 feet.

It might be exactly what you need if you have lots of features and trees that require you to move around. It is easy to operate and a sturdy built, that ensures durability.

Why We Like It

All in all, Worx WG799 has perhaps one of the best advantages: zero carbon emission and innovative battery technology.

The smart design makes it easy and convenient to use. It is clear that it comes with numerous features that you would expect from higher-end products, and can cover up to 5,500 square feet at once.
