Houselife 40V Cordless Lawn Mower Compatible with Dewalt vs PowerSmart 21" 2-in-1 Push Lawn Mower, 144cc
Updated July 2026 — full head-to-head comparison.
Overview of the Products
When it comes to lawn maintenance, both the 40V Cordless Lawn Mower compatible with Dewalt 2x20V MAX Battery and the PowerSmart 21" 2-in-1 Push Lawn Mower are designed to tackle grass cutting efficiently. The cordless mower is priced at $199.99, making it about 29% cheaper than the PowerSmart mower, which retails for $279.99. This price difference might influence your decision, especially if you are budget-conscious.
Performance
The performance of a lawn mower is critical, and both models deliver in their own right. The 40V Cordless Lawn Mower boasts a high-torque upgraded copper motor and premium steel blades, providing consistent cut quality, even in dense grass. Meanwhile, the PowerSmart features a robust 4-stroke OHV 144cc engine, ensuring reliability and efficiency. Although both mowers come with adjustable cutting heights, the PowerSmart offers a range from 1.5 to 3.9 inches, while the cordless mower ranges from 0.98 to 3 inches. This means that the PowerSmart mower may be better suited to achieving a variety of lawn finishes.
Cutting Capability
Cutting capability is another key differentiator. The 40V Cordless Lawn Mower has a 14-inch cutting width, which is wider than many common models, and is designed for easy maneuverability. In contrast, the PowerSmart 21" mower features a larger 21-inch cutting width, allowing it to cover more ground in a single pass. This could significantly reduce mowing time for larger yards. Thus, for those prioritizing cutting efficiency, the PowerSmart may be the more effective choice.
Design and Usability
In terms of design and usability, both mowers have unique advantages. The 40V Cordless Lawn Mower is lightweight at only 22 lbs, making it easy to handle, particularly for seniors or those with smaller yards. It also folds for compact storage. On the other hand, the PowerSmart mower weighs 62 lbs, which is considerably heavier, but its design includes high wheels that enhance maneuverability over uneven terrain. If ease of use is paramount, the lightweight design of the cordless mower may be more appealing.
Grass Collection and Maintenance
Grass collection is vital for maintaining a tidy lawn. The 40V Cordless Lawn Mower comes with a 35L grass collection bag, which minimizes interruptions during mowing sessions. The PowerSmart mower, while it includes both bagging and mulching capabilities, does not specify the size of its grass bag. The mulching feature can improve soil health by returning nutrients to the lawn, making the PowerSmart potentially better for those looking to enhance their yard’s eco-friendliness.
Safety Features
Both models incorporate safety features that ensure user protection. The 40V Cordless Lawn Mower has a double safety switch to prevent accidental starts, which is essential for safe operation. The PowerSmart includes a start/stop control lever that allows immediate stopping of the mower, providing peace of mind during operation. While both offer adequate safety measures, the unique features address different aspects of user safety.
Price Comparison
Price is a significant factor when choosing a lawn mower. The 40V Cordless Lawn Mower is priced at $199.99, while the PowerSmart is $279.99. This makes the cordless mower approximately 29% cheaper than its competitor, which could be a decisive factor for many consumers. If you're looking for a cost-effective solution for lawn maintenance, the 40V model provides excellent value for its price, especially given its features.
Which should you buy?
Choosing between the 40V Cordless Lawn Mower and the PowerSmart 21" 2-in-1 Push Lawn Mower depends largely on your specific needs. If you prioritize portability, lightweight design, and a lower price, the 40V model is the better option. However, if you have a larger yard and prefer a mower with a more powerful engine and wider cutting capability, the PowerSmart may be worth the extra investment. Ultimately, both mowers offer distinct advantages that cater to different lawn care preferences.
