Earthwise LSW70021 21-Inch Width Leaf & Grass Push vs PowerSmart Self Propelled Gas Lawn Mower 21-inch
Updated July 2026 — full head-to-head comparison.
Overview of the Products
The Earthwise LSW70021 lawn sweeper is priced at $129.99, while the PowerSmart self-propelled gas lawn mower comes in at $339.99. This makes the lawn sweeper about 62% cheaper than the mower, appealing to budget-conscious consumers. Both products serve essential roles in lawn care but cater to different needs and user experiences.
Intended Use
The Earthwise LSW70021 is specifically designed for collecting dry leaves and light yard debris, making it ideal for well-maintained lawns. It performs best on flat surfaces and short grass, requiring multiple passes for effective cleanup. In contrast, the PowerSmart mower is a versatile 3-in-1 machine that can mulch, side-discharge, or bag grass clippings, making it suitable for various mowing needs. The mower’s capabilities make it more versatile for general lawn maintenance compared to the sweeper's specialized function.
Design and Build Quality
The Earthwise sweeper features a 21-inch sweeping width and a medium-capacity 2.6-bushel collection bag, designed to make yard cleanups easier. It is built for use on maintained lawns and is less effective on uneven terrain. The PowerSmart mower, on the other hand, boasts a rugged 21-inch steel deck and a powerful 170cc OHV engine. This design not only enhances durability but also improves cutting efficiency, making it a robust choice for a variety of mowing tasks.
Performance
When it comes to performance, the Earthwise sweeper excels in collecting dry leaves and light debris, especially on freshly mowed lawns. However, it struggles with wet leaves and heavier debris. The PowerSmart mower's self-propelled rear-wheel-drive system offers great traction on slopes and uneven terrain, with a single speed ranging from 3.5 to 4.1 km/h. This makes the mower a more capable option for diverse lawn conditions compared to the sweeper, which has limited effectiveness based on grass height and terrain.
Maintenance and Ease of Use
The Earthwise sweeper is relatively low maintenance, requiring users to adjust the brush height for optimal performance. However, it may necessitate multiple bag dumps during use, which can interrupt the cleaning process. The PowerSmart mower, with its recoil starter and auto choke, is designed for easy starting and operation. Its foldable design saves storage space and enhances convenience, making it easier to maneuver and maintain.
Price Comparison
With a price of $129.99, the Earthwise sweeper is significantly cheaper than the PowerSmart mower, which retails for $339.99. The approximately $210 price difference highlights the cost-effectiveness of the sweeper for those primarily focused on leaf collection. However, for users seeking a multifunctional lawn care solution, the investment in the mower may provide better long-term value given its versatility.
Customer Popularity
The Earthwise LSW70021 holds a bestseller rank of 6474, indicating a solid level of popularity among consumers looking for an effective lawn sweeper. The PowerSmart mower, with a bestseller rank of 9309, is also well-regarded but ranks lower in comparison. This could suggest that the sweeper is more widely recognized for its specific functionality, while the mower appeals to a broader audience.
Which should you buy?
Choosing between the Earthwise LSW70021 and the PowerSmart self-propelled gas lawn mower largely depends on your specific lawn care needs. If you primarily need a tool for collecting leaves and light debris from a maintained lawn, the Earthwise sweeper at $129.99 offers a cost-effective solution. However, if you require a more versatile machine capable of mowing, mulching, and bagging grass clippings, the PowerSmart mower, priced at $339.99, would be a better long-term investment. Ultimately, consider your lawn size, terrain, and maintenance preferences when making your decision.
