Differences Between Worx WR150 vs Worx WR155
Below is a summary of the specifications:
Cutting Performance and Efficiency
The Worx WR150 is designed for lawns up to ½ acre, equipped with a 9-inch (22 cm) cutting width that efficiently covers large areas while maintaining clean and uniform cutting results. Its three-blade floating cutting system adapts to uneven ground, ensuring even cuts across various terrains. With an adjustable cutting height from 1.5 to 3.5 inches, the WR150 handles both fine trimming and thicker grass varieties with ease. The AIA™ navigation system enables optimized mowing paths, reducing time spent re-covering areas and increasing battery efficiency.
The Worx WR155 improves on this foundation with the same cutting width and height range but introduces enhanced performance through its higher-capacity 6.0Ah battery, allowing longer operation and fewer charging cycles. This makes it better suited for dense grass or extended mowing sessions. Both models are highly effective on slopes up to 20°, maintaining consistent performance on varied surfaces.
For homeowners prioritizing speed and efficiency, both mowers deliver exceptional performance, but the WR155’s superior runtime translates into fewer interruptions and more complete mowing cycles in large lawns.
Winner: Worx WR155 — With greater battery endurance and extended runtime, it’s more efficient for maintaining expansive yards.
Both the WR150 and WR155 employ Worx’s AIA™ (Artificial Intelligence Algorithm) navigation, a sophisticated pathing system that ensures the mower follows structured patterns instead of random routes. This technology allows them to maneuver narrow passages, optimize coverage, and prevent repeated mowing in already-cut zones.
The WR150 connects via Wi-Fi to the Worx Landroid app, offering remote control, scheduling, and tracking capabilities. It handles multi-zone mowing through the app, allowing users to define separate lawn areas or exclude certain zones using the Off-Limits module (available separately). It navigates efficiently but occasionally requires more boundary fine-tuning for irregular yards.
The WR155, on the other hand, integrates both Wi-Fi and Bluetooth connectivity, ensuring stronger and faster communication with the app, even when the Wi-Fi signal is weak. This model’s improved onboard processor enhances path recalculations and responsiveness, resulting in more accurate mowing along edges and corners. It’s also compatible with optional accessories like the Find My Landroid GPS tracker and ACS anti-collision system, allowing even smarter navigation in complex environments.
Winner: Worx WR155 — Dual connectivity and enhanced processing deliver smoother, more reliable navigation for large or complex lawns.
Battery Capacity and Runtime
Power is one of the defining factors separating these two models. The Worx WR150 uses a 20V 4.0Ah PowerShare battery, which delivers up to 90 minutes of continuous mowing. It’s sufficient for most mid-sized lawns, and because it uses the Worx PowerShare system, the battery is interchangeable with other 20V Worx power tools. This feature adds flexibility for users who already own Worx devices.
The WR155 ups the ante with a 20V 6.0Ah battery, providing up to 120 minutes of runtime on a single charge. That 30-minute difference may seem small, but in real-world terms, it allows the mower to cover an additional 200–300 square meters before returning to the charging base. Both models share a 90-minute recharge time, maintaining efficient turnaround for continuous operation.
For homeowners with dense grass or uneven terrain, the WR155’s additional power ensures smoother operation without mid-cycle charging interruptions.
Winner: Worx WR155 — Its larger battery capacity translates directly into longer runtime, greater coverage, and improved performance per session.
Design, Build Quality, and Terrain Handling
Both models exhibit Worx’s characteristic durability and ergonomic design, built with reinforced plastic casings and weatherproof coatings rated for outdoor operation. They’re resistant to rain, dirt, and UV exposure, making them ideal for extended outdoor placement. The WR150 weighs around 22 lbs, offering easy mobility when relocated or cleaned. Its compact form factor allows it to fit through narrow gates and tight corners.
The WR155, being slightly heavier at 26.5 lbs, has enhanced traction and stability on slopes and rough ground. Both mowers include floating decks that adapt dynamically to bumps or uneven surfaces, maintaining a consistent cutting height even across dips or rises. With noise levels capped below 65 dB, both models perform quietly enough for early-morning or nighttime mowing without disturbing neighbors.
In overall build quality, both feel solid and premium, though the WR155’s added mass and refined stability make it more reliable for large, mixed-terrain gardens.
Winner: Worx WR155 — Slightly sturdier build and improved slope stability give it the advantage for rugged or expansive lawns.
Smart Features and App Integration
Both the WR150 and WR155 integrate seamlessly with the Worx Landroid mobile app, which acts as the command hub for controlling, monitoring, and updating the mower. Through the app, users can adjust mowing schedules, set work zones, monitor battery status, and receive notifications or firmware updates. Over-the-air software updates ensure both models evolve over time, improving navigation and performance through machine learning.
The WR150 offers complete functionality via Wi-Fi, enabling scheduling, start/stop commands, and anti-theft notifications. It’s also compatible with accessories like the Off-Limits digital fencing system, ACS obstacle-avoidance sensor, and Find My Landroid GPS tracker.
The WR155 includes all of the above but adds Bluetooth pairing, improving responsiveness when you’re nearby. It supports voice assistant integrations like Amazon Alexa and Google Assistant, allowing voice control for starting or stopping mowing tasks. The improved app synchronization also enables multi-zone management, letting users control several areas in larger gardens with precision.
Winner: Worx WR155 — Broader connectivity options and advanced app integration make it the smarter and more connected choice.
