Differences Between Worx WR147 vs Worx WR155
Below is a summary of the specifications:
Cutting Performance and Efficiency
The Worx WR147 is designed for smaller and medium-sized lawns, offering a cutting capacity of up to ¼ acre (approximately 1,000 m²). It uses an 8-inch cutting deck with a three-blade cutting disc that provides precise and efficient mowing results. The adjustable cutting height between 1.5 and 3.5 inches makes it suitable for various grass types and seasonal conditions. Its AIA™ (Artificial Intelligence Algorithm) ensures that the mower follows efficient routes instead of random patterns, reducing time while improving consistency across the lawn.
The Worx WR155, on the other hand, extends coverage to ½ acre (2,000 m²)—double the area of the WR147. Despite having the same cutting width, its higher battery capacity allows it to mow continuously for nearly two hours per charge. The consistent height adjustment range remains the same, maintaining flexibility for different mowing needs. It’s ideal for users who need a mower that can handle large, open areas or multiple mowing zones with fewer recharges.
Both mowers feature floating decks that adapt to uneven terrain, ensuring even cuts. However, the WR155’s higher power output and runtime provide a noticeable edge in overall efficiency and coverage for larger properties.
Winner: Worx WR155 — It offers longer runtime, larger mowing area, and improved endurance for extensive lawns.
Both models employ Worx’s intelligent AIA™ Navigation System, a standout feature that allows the mower to maneuver efficiently through narrow passages, corners, and complex garden layouts. The WR147 excels in small yards, efficiently navigating pathways and reducing redundant passes, which saves both time and energy.
The WR155 enhances this system further by integrating Bluetooth connectivity alongside Wi-Fi, resulting in more stable communication with the Worx Landroid app. The upgraded hardware also enables smoother multi-zone mapping and improved responsiveness when adjusting schedules or lawn boundaries remotely. Additionally, both models use boundary wire systems for perimeter setup, ensuring accurate coverage without skipping edges.
While both deliver intelligent navigation, the WR155’s broader connectivity options and upgraded responsiveness make it more suitable for users who demand better lawn management flexibility.
Winner: Worx WR155 — Enhanced connectivity and improved multi-zone handling make it superior for complex yards.
Battery Capacity and Runtime
The Worx WR147 operates on a 20V 4.0Ah PowerShare battery, sufficient for small to medium lawns. It runs for around 60 to 75 minutes per charge, depending on terrain and grass density. The PowerShare ecosystem allows users to interchange the battery with other Worx 20V tools, offering additional convenience for homeowners already invested in the brand.
The WR155 is equipped with a larger 6.0Ah battery, extending its runtime to roughly 90 to 120 minutes, which means fewer charging cycles and less downtime. The recharging duration for both remains around 90 minutes, but the WR155’s longer mowing session per charge translates to higher productivity.
Both models utilize energy-efficient brushless motors, ensuring longer motor life and reduced maintenance. However, for users with expansive lawns or thicker grass, the WR155’s battery endurance provides a more practical and powerful advantage.
Winner: Worx WR155 — Its higher-capacity battery and extended runtime make it the more capable and durable option.
Design, Build Quality, and Terrain Handling
Both models showcase the robust and weather-resistant design that the Landroid line is known for. Their compact dimensions allow easy movement around garden beds, trees, and narrow spaces. The WR147’s lighter 9 kg body makes it easier to lift, clean, or transport, while the WR155’s heavier 12 kg frame enhances stability on sloped or uneven surfaces.
In terms of slope performance, both handle inclines up to 20° (35%), making them reliable for most residential landscapes. They also feature floating blade decks that adapt to changing ground contours, maintaining even cuts even on bumpy lawns. The noise level of ≤65 dB ensures that both mowers operate quietly enough for daytime or evening use without disturbing neighbors.
While build quality is similar, the WR155 feels sturdier, reflecting its intended use for larger, more demanding lawns. The additional weight adds better traction and control, particularly when handling slopes or thicker grass.
Winner: Tie — Both models are durable and efficient, but the WR155 has a slight edge for stability on larger terrains.
Smart Features and App Integration
Both the Worx WR147 and WR155 integrate with the Worx Landroid mobile app, allowing users to manage mowing schedules, set zones, monitor performance, and adjust cutting parameters remotely. Users can receive notifications, start or stop mowing, and check mower status directly from their smartphones. Both models connect via Wi-Fi, but the WR155 also includes Bluetooth, offering faster local pairing and better reliability when Wi-Fi signals are weak.
The app’s intelligent features include weather-based scheduling, anti-theft protection, and over-the-air firmware updates, ensuring that both models stay optimized for performance. Optional accessories such as the ACS (Anti-Collision System) and Find My Landroid GPS module are compatible with both units, further enhancing safety and tracking.
While the WR147 provides all the essential smart controls expected from a robotic mower, the WR155 expands this ecosystem with greater compatibility and improved connectivity. It’s designed for users seeking a more autonomous and advanced mowing experience.
Winner: Worx WR155 — Its dual connectivity and superior integration make it more flexible for connected lawn management.
