Overview of the Products

The Earthwise LSW70021 and PowerSmart Push Electric Lawn Mower are both priced at $129.99, making them equally accessible options for lawn care. However, they cater to different needs: the Earthwise is a lawn sweeper designed for collecting leaves and light debris, while the PowerSmart is a mower built for cutting grass. This fundamental difference in purpose is crucial when choosing the right tool for your lawn care needs.

Design and Build Quality

The Earthwise LSW70021 features a 21-inch sweeping width, making it well-suited for efficiently collecting leaves and debris from maintained lawns. Its design incorporates a medium-capacity 2.6-bushel collection bag, allowing for moderate storage during use. In contrast, the PowerSmart mower has a 14-inch cutting width and a lightweight, corded design that makes it easy to maneuver. The adjustable handle height adds comfort for various users. While both products are designed for ease of use, the Earthwise’s larger sweep means fewer passes are needed in ideal conditions, though it may require multiple passes in more challenging situations.

Performance and Efficiency

The performance of the Earthwise LSW70021 excels on short grass and flat surfaces, particularly when the lawn is recently mowed. It is designed to collect dry leaves and light debris effectively but struggles with anything heavier, like rocks or wet leaves. The PowerSmart mower, equipped with a 12.5 Amp motor, provides a robust solution for cutting grass, boasting six adjustable cutting heights ranging from 1 to 3 inches. Therefore, if maintaining grass length is your primary concern, the PowerSmart may be the more efficient choice.

Ease of Use

Both products emphasize user-friendliness but in different contexts. The Earthwise LSW70021 requires users to make several passes for optimal results, especially on uneven terrain. Its brush height is adjustable, ensuring proper contact with the lawn surface, which is crucial for effective debris collection. The PowerSmart mower, however, is designed for straightforward operation with its corded electric mechanism. It has a 10-gallon grass bag with a level indicator to signal when it needs emptying, making the mowing process more efficient. The lightweight design also makes it easier to handle, especially for smaller yards.

Maintenance and Storage

In terms of maintenance, the Earthwise LSW70021 is fairly straightforward, requiring users to ensure the brushes are adjusted correctly for the best performance. The PowerSmart mower has a more complex set of requirements, including checking blade screws and ensuring the power cord is intact before use. Both products are relatively easy to store, but the PowerSmart features a foldable handle, making it more compact for storage in smaller spaces.

Environmental Impact

Both the Earthwise LSW70021 and the PowerSmart mower are designed with environmental considerations in mind. The Earthwise model is a manual sweeper, which means it requires no electricity or fuel, reducing carbon emissions. On the other hand, the PowerSmart is a corded electric mower, which eliminates gas emissions while in operation. However, it does rely on electricity, making it important to consider the energy source. For users prioritizing sustainability, both options present eco-friendly choices, though they function in different capacities.

Pricing and Value

At $129.99, both the Earthwise LSW70021 and PowerSmart mower provide comparable pricing but offer different value propositions. The Earthwise has a 30-day average price of about $128.23, indicating a stable market position with a sales rank of 6474. The PowerSmart, while also priced at $129.99, has a slightly higher average price of $132.42 over 90 days and a sales rank of 32078. This may suggest that while both products are popular, the Earthwise LSW70021 might be more favored among consumers seeking a lawn sweeper.

Which should you buy?

Choosing between the Earthwise LSW70021 and the PowerSmart Push Electric Lawn Mower ultimately depends on your specific lawn care needs. If you're looking for an effective way to collect leaves and light debris, the Earthwise sweeper is an excellent choice, particularly for recently mowed lawns. Conversely, if you're focused on maintaining grass length and prefer a gasless mowing solution for small to medium-sized yards, the PowerSmart mower is likely the better option. Both are priced the same at $129.99, but their different functionalities cater to distinct lawn care tasks.
