  • Easy to Start: 9/10
  • Power: 8/10
  • Maintenance Requirements: 9/10
  • Rough Terrain: 7/10

In the easy-to-start category, the 24V-X2-21LM has a high rating of 9 out of 10. This testifies that starting the machine is simple since it is a cordless electric mower, as opposed to gas-powered equivalents that require pull cords or complex choke systems. It allows users to start mowing quickly and easily with a simple push-button start.

In terms of power, the 24V-X2-21LM receives an 8 out of 10. While it lacks the sheer power of gas-powered lawn mowers, its 24V rechargeable lithium-ion batteries give enough power to cut grass efficiently even in moderately dense regions.

The 24V-X2-21LM is developed with user comfort in mind, earning a solid 9 out of 10 for the maintenance requirements. As a battery-operated mower, it eliminates the need for fuel, oil changes, and spark plug replacements, substantially simplifying maintenance.

In the last category, it gets a 7 out of 10 for handling tough terrain. Its rear-wheel drive technology improves maneuverability and traction, allowing users to easily cross uneven areas. However, it may be limited to particularly harsh or extremely hilly terrains.


This mower tries to address the constraints of existing gas-powered options by focusing on sustainability and convenience of usage. The 24V rechargeable lithium-ion battery and 21-inch steel blade promise a smooth mowing experience with great cutting performance.

The brushless feature is a notable highlight, raising its performance and efficiency to a higher level. The use of a brushless motor distinguishes it from many other cordless models on the market, as it provides more efficient and dependable power delivery while minimizing friction and wear on internal components.

This not only increases the overall lifespan of the mower but also maximizes battery duration by optimizing power use. Now users can enjoy a consistent and vigorous cutting performance with the brushless motor without sacrificing battery life.Built Quality of Sun Joe 24V X2 21LM

As a result, the 1100 Watt max brushless cordless lawn mower is both powerful and environmentally friendly, giving homeowners comfort without losing cutting capabilities. The 24V-X2-21LM’s brushless feature solidifies its status as a top-tier pick for modern lawn care, giving a greener, quieter, and more efficient mowing experience for all users.

However, one drawback of this cordless mower is the time it takes to charge the battery. Charging lithium-ion batteries might take a long time, which may cause disruptions during lengthy mowing activities. While the presence of two batteries addresses this issue to some extent, customers still have to wait for the batteries to charge before mowing large lawns.

Also, it does not have a mulching function, unlike several other lawnmowers on the market. Mulching is a convenient feature that allows customers to recycle grass clippings back into the lawn, adding nutrients to the soil and decreasing the need for fertilizers. The lack of this capability may be a detriment to individuals who prefer to mulch.

Users can purchase the Sun Joe 24V battery or replacements via authorized Sun Joe dealers or hardware stores. Furthermore, because the battery is compatible with other Sun Joe 24V-X2 series mowers, it is a versatile investment for homeowners who own various lawn care instruments from the same line.

– How Has the Sun Joe 24V-X2-21LM Evolved?

The Sun Joe 24V-X2-21LM has evolved by combining modern technology and user expectations. This model diverted lawn care trends towards more eco-friendly and user-friendly solutions, adding a cordless feature too, as it focused on a powerful and efficient mower while remaining environmentally sensitive.Improvement of Sun Joe 24V X2 21LM

The 24V-X2-21LM differs from the Sun Joe 48V lawn mower and Sun Joe 24V-X2-DTS15-CT in terms of battery power and cutting capabilities. The 24V-X2-21LM and 24V-X2-DTS15-CT both have a 24V dual-battery setup that provides enough runtime for medium-sized lawns. The 24V-X2-DTS15-CT, on the other hand, has the extra benefit of a dual-blade design, which improves cutting efficiency and versatility for different grass kinds.

The Sun Joe 48V, however, has a more powerful Sun Joe 48V battery, which provides enhanced cutting capability for larger yards and rougher terrain. When compared to 24V models, its higher voltage contributes to improved torque and cutting capabilities, making it ideal for difficult mowing circumstances.

When compared to the Sun Joe 24V-X2-17LM 48-volt 17-inch mulching walk-behind lawn mower recall, we see that the 24V-X2-21LM has a larger 21-inch cutting width compared to the 17-inch of the Sun Joe 24V-X2-17LM recall. However, the Sun Joe 24V-X2-17LM replacement blade does offer mulching capabilities, which are not present in the Sun Joe 24V-X2-21LM 48V cordless lawn mower.

While the 24V-X2-21LM, 24V-X2-DTS15-CT, and 48V cater to distinct lawn care needs, they all share Sun Joe’s dedication to delivering environmentally friendly alternatives to typical gas-powered mowers. Each represents an advancement in cordless mower technology, addressing varied user requirements and preferences to suit the diverse needs of modern lawn care enthusiasts.
