Updated July 2026 — full head-to-head comparison.

Overview of the Products

When comparing the STEELITE 21V 13-Inch Brushless Electric Lawn Mower and the WORX Nitro 21" Cordless Lawn Mower, there is a notable price difference of about 63%—the STEELITE retails for $139.99, while the WORX is priced at $379.99. This significant disparity suggests that budget-conscious consumers may lean towards the STEELITE, but it's essential to evaluate the features and performance of both mowers to determine which one best fits your needs.

Design and Build Quality

The STEELITE is designed with a compact 13-inch deck, making it lightweight at just 20.5 lbs, which is ideal for maneuvering in small yards and tight spaces. In contrast, the WORX features a larger 21-inch cutting deck, which enhances efficiency for larger lawns, particularly those up to half an acre. While the STEELITE is easier to store due to its small size, the WORX's robust design promises longevity with a high-strength polymer deck that resists impact damage and corrosion. Thus, if you prioritize portability and storage, the STEELITE may be your choice. However, for larger mowing tasks, the WORX design provides better coverage.

Power and Runtime

The STEELITE operates on a 21V 4.0Ah battery, offering up to 25 minutes of runtime on small to mid-sized lawns. On the other hand, the WORX is equipped with two 20V 5.0Ah batteries, providing a maximum no-load runtime of 50 minutes, making it more suitable for larger areas. The WORX also boasts a brushless motor that delivers 40% more power and longer runtime compared to earlier models. Thus, for extensive lawns, the WORX clearly outperforms the STEELITE in terms of power and runtime efficiency.

Cutting Performance

The cutting performance of both mowers is impressive, but they differ in adjustment capabilities. The STEELITE features a 5-level height adjustment ranging from 0.98 inches to 2.56 inches, allowing for some customization based on lawn conditions. In contrast, the WORX offers a wider 7-position height adjustment from 1.5 inches to 4 inches, which provides greater flexibility for various grass types and lengths. Additionally, the WORX incorporates Aerodeck Technology, which enhances air volume in the cutting deck to prevent clogs and improve cut quality. Therefore, if cutting versatility and quality are priorities, the WORX takes the lead.

Functionality and Versatility

Both mowers offer mulching and bagging capabilities, enhancing their functionality. The STEELITE includes an 8-gallon grass bag for easy collection or detaching for natural mulching. Similarly, the WORX supports 3-in-1 functionality: mulching, bagging, and rear side-discharging, making it more versatile for different mowing needs. The WORX also comes with a mulch plug and discharge chute for easy mode switching, while the STEELITE is more straightforward but limited by its single function. Therefore, if you desire flexibility in lawn care, the WORX presents a more comprehensive solution.

User Experience and Maneuverability

User experience significantly differs between the two models. The STEELITE’s lightweight design makes it easy to maneuver, especially in small yards or on slopes. Conversely, the WORX, while still manageable, is heavier due to its larger build. However, it compensates with features like a fully collapsible handle for convenient storage and a single-lever height adjustment for quick changes. The onboard charge-level indicator in the WORX also provides users with real-time battery status. For ease of use and storage, the STEELITE excels, but the WORX offers advanced features that enhance the overall mowing experience.

Price and Value

The STEELITE is priced at $139.99, making it about 63% cheaper than the WORX, which is $379.99. While the lower price may be appealing, it’s crucial to consider the value offered by each mower. The STEELITE provides a solid choice for those with smaller lawns who need a lightweight and easy-to-use mower. However, the WORX, with its advanced technology, longer runtime, and greater versatility, may justify its higher price for those managing larger areas or seeking superior cutting performance. Thus, your choice will depend on your lawn size and specific needs.

Which should you buy?

Ultimately, the decision between the STEELITE 21V 13-Inch Brushless Electric Lawn Mower and the WORX Nitro 21" Cordless Lawn Mower hinges on your individual requirements. If you have a small yard and prefer a lightweight, easy-to-store option, the STEELITE is a compelling choice at $139.99. However, if you maintain a larger lawn and value advanced features, longer runtime, and cutting versatility, the WORX at $379.99 offers significant advantages. Consider your lawn's size, your budget, and the features that matter most to you when making your decision.
