Price Comparison

When comparing the EGO POWER+ Electric Lawn Mower and the RB 9" Small Lawn Mower, the price difference is significant. The EGO POWER+ is priced at $649.00, while the RB small mower is about 74% cheaper at $169.99. This price disparity may appeal to budget-conscious consumers who need a more economical option for maintaining their lawns. However, the higher price of the EGO mower reflects its advanced features and capabilities, making it suitable for larger and more complex mowing tasks.

Performance and Power

The EGO POWER+ Electric Lawn Mower is designed for high performance, featuring a high-efficiency brushless motor and a powerful 56V 7.5Ah battery that provides up to 60 minutes of run time on a single charge. In contrast, the RB 9" Small Lawn Mower, with its 40V 2Ah battery, is ideal for small lawns up to 540 sq.ft. While the RB mower is efficient for its intended use, it operates at a lower power level compared to the EGO model, which is capable of handling more extensive and demanding mowing jobs.

Cutting Technology

The cutting technology in the EGO POWER+ features a Select Cut Multi-Blade System with interchangeable blades, allowing users to choose between mulching, bagging, or side discharge functions. This versatility ensures superior cutting performance that can exceed traditional gas mowers. The RB small mower offers three adjustable cutting heights from 1.2" to 2", making it suitable for maintaining small, well-groomed lawns. While the RB mower provides basic cutting capabilities, it lacks the advanced options available in the EGO mower.

Design and Maneuverability

The RB 9" Small Lawn Mower is ultra-light and compact, weighing only 11.5 lbs without the battery. This design allows for easy maneuverability in tight spaces and corners. Its one-hand steering and pivoting front wheels make it highly suitable for small yards. In contrast, the EGO POWER+ is larger and heavier, designed for performance rather than compactness. While the EGO mower may be more challenging to navigate in confined spaces, it is built for efficiency in larger areas, where its self-propelled technology shines.

Battery Life and Charging

Battery life is a critical factor in lawn mower performance. The EGO POWER+ boasts a 56V 7.5Ah battery that charges in about 60 minutes, offering a robust run time that allows for extensive mowing without interruption. On the other hand, the RB 9" mower's 40V 2Ah battery is suitable for smaller spaces but will require more frequent recharging for larger tasks. The EGO mower's superior battery performance aligns with its higher price point, making it a better option for those needing extended mowing sessions.

Safety Features

Safety is an essential consideration for any lawn mower. The RB 9" Small Lawn Mower includes advanced safety features that stop the mower automatically if it is tilted beyond 20°–70°, adhering to US safety standards. This feature makes it a reliable choice for beginners and those unfamiliar with lawn maintenance. While the EGO POWER+ does not specifically highlight safety features, its robust design and high-performance capabilities can offer a safe user experience when operated correctly.

Storage Solutions

Storage options differ significantly between the two products. The RB 9" Small Lawn Mower features a detachable aluminum handle and an upright storage design that saves up to 70% of space, making it ideal for users with limited storage space. The EGO POWER+, while efficient, does not emphasize compact storage solutions, which could be a drawback for those with smaller garages or sheds. The compact design of the RB mower makes it more suitable for urban environments where space is often at a premium.

Which should you buy?

Deciding between the EGO POWER+ Electric Lawn Mower and the RB 9" Small Lawn Mower depends largely on your lawn care needs and budget. If you have a larger yard and require advanced cutting technology with a powerful motor, the EGO POWER+ is worth the investment at $649.00. However, for those with small lawns or limited space, the RB mower at $169.99 offers an economical and highly maneuverable solution. Ultimately, your choice should reflect the size of your lawn, the complexity of your mowing tasks, and your budget constraints.
