Dimension comparison
Design and Size
The RB 9" Small Lawn Mower for Small Spaces is significantly lighter and more compact than the 40V Cordless Lawn Mower. Weighing only 11.5 lbs without the battery, the RB model is ultra-light, making it easy to maneuver in tight spaces. In contrast, the Houselife mower weighs 22 lbs, which is almost double the weight, potentially making it more cumbersome for users with limited strength or mobility. The compact design of the RB mower allows for upright storage, saving up to 70% of space, which is a significant advantage for those with limited storage options.
Power and Performance
The Houselife mower boasts a 40V power system compatible with Dewalt 20V MAX batteries, delivering consistent performance for maintaining your lawn. It features a high-torque copper motor and premium steel blades, which provide sharp cuts even in dense grass. On the other hand, the RB mower is equipped with a high-speed brushless motor that runs at 6000 RPM, making it efficient for small lawns up to 540 sq.ft. While both mowers are designed for performance, the Houselife mower is tailored for broader applications due to its wider cutting path of 14 inches compared to the RB's 9-inch cutting width.
Cutting Height Adjustments
The Houselife mower offers six cutting heights ranging from 0.98 to 3 inches, allowing users to tailor their mowing to various grass types and seasonal growth. This flexibility is particularly beneficial for diverse lawns where different areas may require different cutting heights. In contrast, the RB mower provides three adjustable cutting heights between 1.2 and 2 inches. While this offers some customization, it is less versatile compared to the Houselife mower, which may be a consideration for those wanting to achieve a more precise lawn care routine.
Grass Collection and Maintenance
When it comes to grass collection, the Houselife mower features a 35L (9.25 gallons) grass collection bag, which minimizes the frequency of interruptions during mowing sessions. This larger capacity is ideal for users with mid-sized lawns who prefer to mow without frequent stops. The RB mower, however, does not specify a grass collection capability, indicating that it may not be as efficient for larger areas. Users with small yards may find the RB mower suitable, but those with bigger lawns might prefer the more robust collection system of the Houselife mower.
Ease of Use and Maneuverability
The ultra-lightweight design of the RB mower allows for easy maneuverability, especially in tight areas and corners. Its one-hand steering feature makes it user-friendly, particularly for those who might struggle with heavier equipment. Comparatively, the Houselife mower, while still manageable, may require more effort to navigate around obstacles due to its increased weight. Both mowers are designed with user safety in mind, but the RB mower's lightweight and compact nature may offer a more accessible mowing experience for seniors or beginners.
Battery and Charger Considerations
The Houselife mower is designed as a bare tool, requiring two 20V Dewalt batteries (not included) to operate at 40V. This feature makes it more suitable for users who already own Dewalt batteries and are looking to expand their collection without incurring additional costs. In contrast, the RB model includes a 40V 2Ah battery and charger, making it ready to use right out of the box. This all-in-one package may be more appealing for first-time buyers who do not already own compatible batteries, providing added convenience.
Price Comparison
The Houselife mower is priced at $199.99, while the RB mower is available for $169.99, making the RB approximately 17% cheaper. This price difference could be a significant factor for budget-conscious consumers. While the Houselife mower may offer more features and a wider cutting width, the lower price of the RB mower makes it an attractive option for those with smaller lawns and simpler mowing needs.
Which should you buy?
Choosing between the Houselife 40V Cordless Lawn Mower and the RB 9" Small Lawn Mower depends largely on your specific needs and lawn size. If you have a medium-sized yard and prefer a mower that offers more power, versatility, and larger grass collection, the Houselife mower is a solid choice. However, if you have a small lawn and prioritize ease of use, compactness, and lower cost, the RB mower presents a compelling option. Ultimately, your decision should reflect your lawn care requirements, budget, and storage capabilities.
