Overview of the RB 9" Small Lawn Mower

The RB 9" Small Lawn Mower is designed for small spaces, making it an ideal choice for those with compact yards. Priced at $169.99, it offers a lightweight and maneuverable option with a brushless motor that operates at a high speed of 6000 RPM. This mower can handle lawns up to 540 square feet and features three adjustable cutting heights. With its focus on ease of use and storage, it is particularly well-suited for beginners or those with minimal lawn care needs.

Overview of the WEN 20V Max 2-in-1 Lawn Mower

The WEN 20V Max 2-in-1 Lawn Mower is a more versatile solution, priced at $226.89. It serves as both a mower and a mulcher, making it a multifaceted tool for yard maintenance. This model features a 19-inch cutting deck and can manage lawns up to 10,300 square feet on a single charge with the included two 5Ah batteries. Its design emphasizes power and performance, with a brushless motor that operates more efficiently than traditional motors.

Price Comparison

The RB 9" Small Lawn Mower is approximately 25% cheaper than the WEN 20V Max, making it a budget-friendly option at $169.99 compared to WEN's $226.89. For users with limited space and smaller lawns, the cost savings can be significant, especially when considering that the RB model is specifically tailored for smaller areas. However, as the WEN mower offers more features and capabilities, it may justify its higher price for those needing a more robust lawn care solution.

Performance and Power

Performance-wise, the WEN 20V Max boasts a brushless motor that provides better longevity and efficiency compared to the RB model's motor. The WEN mower can cut grass with a blade rotating at up to 3100 RPM, which, while lower than the RB's 6000 RPM, is still effective over larger areas due to its size and dual-functionality. The RB mower, meanwhile, is more than capable for small yards, efficiently mulching with its high-speed motor, but may struggle in larger or thicker grass conditions.

Cutting Width and Height Options

The WEN 20V Max offers a significant advantage in cutting width and height options, featuring a 19-inch deck compared to the RB's 9-inch blade. This makes the WEN mower a better choice for users with larger lawns or those who prefer fewer passes to achieve a well-manicured yard. Additionally, the WEN mower provides five height settings ranging from 1.5 to 3.2 inches, while the RB offers three heights between 1.2 to 2 inches. This flexibility allows the WEN mower to accommodate various grass types and conditions better than the RB model.

Battery and Runtime

When it comes to battery performance, the WEN 20V Max is equipped with two 5Ah batteries, enabling it to cover larger areas—up to 10,300 square feet—on a single charge. Users can expect an actual runtime of 30 to 68 minutes, depending on grass conditions and cutting height, which offers substantial operational flexibility. The RB mower, powered by a 40V 2Ah battery, is ideal for smaller spaces but has a more limited runtime due to its lower battery capacity. For users with larger lawns, the WEN’s battery setup provides a distinct advantage.

Storage and Maneuverability

The RB 9" Small Lawn Mower excels in maneuverability and storage, weighing only 5.2 kg (11.5 lbs without the battery) and featuring a compact design that allows for one-hand steering. This makes it perfect for navigating tight corners and small areas. Its upright storage capability saves up to 70% space, making it ideal for users with limited storage options. Conversely, while the WEN mower has a collapsible handle for easy storage, its larger size and weight may make it less desirable for those with very small spaces to store their equipment.

Which should you buy?

Choosing between the RB 9" Small Lawn Mower and the WEN 20V Max 2-in-1 Lawn Mower ultimately depends on your specific needs. If you have a small yard and prioritize budget, the RB mower is an excellent choice, offering efficiency and ease of use at a lower price point. However, if you require a more powerful and versatile mower that can handle larger lawns and various tasks like mulching, the WEN 20V Max would be a better investment despite its higher price.
