When it comes to robotic lawn maintenance, Worx Landroid has made a name for itself with efficient, intelligent, and eco-friendly mowers. Two top-tier models in this range—the Worx WR150 vs Worx WR155 —are both designed for lawns up to ½ acre. But despite their similar coverage range, these machines differ in meaningful ways, especially in battery life, cutting system, connectivity, and maintenance.
In this in-depth comparison, we explore all the critical differences between the WR150 vs WR155 so you can choose the ideal smart mower for your yard.

Differences Worx WR150 vs Worx WR155
Below is a summary of the specifications:
Battery Capacity and Runtime Efficiency
The Worx WR150 comes with a 4.0Ah 20V lithium-ion battery, which provides enough juice for most suburban lawns. It can efficiently mow up to ½ acre, returning to its base station to recharge as needed. The recharge cycle typically takes around 90 minutes, with mowing sessions lasting about 70–75 minutes per full charge under average conditions.
On the other hand, the WR155 is equipped with a 6.0Ah battery, offering 50% more capacity. This translates into significantly longer mowing times and fewer interruptions, especially useful for yards with denser turf or complex layouts. The larger battery ensures that the WR155 is better suited for sustained operation over longer mowing cycles.
Winner: WR155
With longer runtime and greater energy reserves, the WR155 handles extended mowing sessions with ease, giving it the edge for efficiency.
Cutting Width and Lawn Coverage Performance
The WR150 features a 9-inch cutting width, slightly wider than the WR155’s 8-inch deck. This allows it to cover more ground with fewer passes, making it slightly more time-efficient on large open lawns.
However, the WR155 compensates for its narrower deck by including a floating blade disc, which adjusts dynamically to the contours of your lawn. This ensures more consistent cutting on uneven or sloped terrain and minimizes the risk of blade obstruction.
Both models feature Cut-to-Edge technology, which reduces the need for trimming lawn edges manually. The uniform finish and minimized edge growth are noticeable after just a few full mowing cycles.
Winner: WR155
Despite the smaller deck, the floating blade disc and adaptive terrain handling give the WR155 a smoother and more precise cut.
Both the WR150 and WR155 use Worx’s proprietary AIA™ (Artificial Intelligence Algorithm), allowing them to navigate narrow corridors, tight corners, and multi-zone gardens more efficiently than random-movement mowers. The algorithm ensures optimized mowing routes and saves energy by reducing redundant paths.
However, the WR155 improves terrain adaptability with its floating blade system, which allows the cutting height to self-adjust on bumps and uneven patches. This results in fewer stops and smoother transitions across hilly or complex yards.
Winner: WR155
Smarter terrain handling through its blade suspension system makes the WR155 more capable on varied topographies.
Smart Features and App Connectivity
The Worx WR150 supports Wi-Fi connectivity and integrates with the Worx Landroid app, which allows users to manage mowing schedules, check status, pause/resume mowing, and update firmware. It’s compatible with voice assistants and receives over-the-air updates for enhanced functionality.
The WR155 takes connectivity a step further by adding Bluetooth support, enabling local communication even when Wi-Fi is unavailable. It also features a more user-friendly LCD display with a scroll wheel, making on-device configuration far more intuitive.
Both models are compatible with the Find My Landroid GPS anti-theft accessory, and both support rain delay functions to avoid mowing in wet conditions.
Winner: WR155
Better connectivity options and an improved interface make the WR155 the smarter, more flexible mower.
Maintenance, Cleaning, and Durability
Maintenance is crucial for robotic lawn mowers. The WR150 has a standard undercarriage that is not waterproof, meaning you need to be careful when cleaning. Manual cleaning with a brush or cloth is required to avoid internal damage.
In contrast, the WR155 boasts a fully waterproof undercarriage, allowing easy rinsing with a hose. This significantly reduces maintenance time and ensures better long-term performance by preventing clippings and debris buildup around the blades.
Winner: WR155
Superior waterproofing and ease of cleaning give the WR155 long-term durability and lower upkeep requirements.
Noise Levels and Eco-Friendly Operation
The WR150 runs at around 63 dB, which is already quiet compared to traditional gas-powered mowers. However, the WR155 brings that number down to just 59 dB, making it nearly imperceptible in many outdoor settings.
Both models are battery-powered, emit zero direct emissions, and are well-suited for eco-conscious homeowners seeking to reduce their carbon footprint.
Winner: WR155
Quieter operation and the same eco-conscious performance make the WR155 more neighborhood-friendly
Weight and Portability
Weighing in at 22.9 lbs, the WR150 is lighter than the WR155’s 24.2 lbs. While this doesn’t affect automated mowing, it does make the WR150 slightly easier to lift, transport, or store when not in use.
If you anticipate needing to move the mower often—for storage, servicing, or reconfiguration—the lighter WR150 might offer a small advantage.
Winner: WR150
Slightly lighter and easier to carry, making it marginally more portable for users who move the unit often.
