Differences Worx WR147 vs Worx WR155
Below is a summary of the specifications:
Lawn Size Coverage and Area Efficiency
The WR147 is built for lawns up to 1/4 acre, making it ideal for small to medium-sized suburban yards with moderate landscaping complexity. Its coverage is best suited for homes with defined boundaries, open areas, and a need for frequent, lightweight mowing sessions.
On the other hand, the WR155 is a robust unit designed for lawns up to 1/2 acre, effectively doubling the coverage capacity. With a wider cutting deck (8 inches) and longer runtime, it’s capable of handling larger, more intricate lawns in fewer passes, reducing total mowing time per session. For properties with more open space or extended mowing zones, the WR155 delivers improved area efficiency.
Winner: Worx WR155
Its increased mowing capacity and wider deck make it the superior choice for larger properties with more ground to cover.
Battery Performance and Charging Efficiency
The WR147 is powered by a 20V 4.0Ah Worx Power Share battery, providing up to 90 minutes of mowing on a single charge. Charging time is relatively fast at around 75 minutes, meaning the mower can complete small-yard sessions with minimal interruption.
In contrast, the WR155 uses a 20V 6.0Ah battery, extending its runtime to an impressive 120 minutes. While its charging time increases to 115 minutes, the benefit of a significantly larger coverage area outweighs the slightly longer charge cycle. Both mowers return autonomously to their charging bases when battery levels are low and resume mowing where they left off.
Winner: Worx WR155
With more runtime and the ability to mow more ground per charge, the WR155 takes the lead in energy efficiency for bigger lawns.
Cutting Height and Deck Versatility
The WR147 offers a cutting height range from 1.5 to 3.5 inches, adjustable via a manual dial. This allows it to handle most common grass types, including fescue, bluegrass, and ryegrass, making it suitable for homeowners seeking a shorter, more manicured look.
The WR155 builds on this by offering a slightly higher maximum cut of 4.0 inches, which is beneficial for lawns with denser or taller grass types like St. Augustine or Bahia. The 8-inch cutting width also means fewer passes are needed to mow the same space, resulting in faster mowing cycles.
Winner: Worx WR155
The expanded height range and wider deck provide more versatility and efficiency for users with varying lawn types.
Both mowers feature AIA™ (Artificial Intelligence Algorithm) navigation, which enables more intelligent route planning compared to traditional random-pattern robotic mowers. They navigate tight spaces, narrow passages, and non-linear yard shapes effectively, making them ideal for modern landscape designs.
With equal slope handling capability (up to 20°) and smooth terrain response, both models adapt to uneven terrain and moderate hills without sacrificing performance. They maneuver well around obstacles and adjust their mowing patterns to ensure full lawn coverage over time.
Winner: Tie
Both models provide intelligent, agile navigation for complex lawns and perform equally well on slopes and irregular terrain.
Smart Features and App Integration
Through the Worx Landroid app, both the WR147 and WR155 offer full remote control functionality. You can set schedules, monitor mowing progress, check battery life, and receive alerts directly from your smartphone. The connection is established via Wi-Fi and Bluetooth, ensuring stable communication during operation.
Each model also supports modular add-ons like the GPS Anti-Theft Module, Off-Limits Virtual Fencing, and Collision Detection Sensor, offering customizable upgrades based on the property layout and user preferences.
Winner: Tie
Both models offer identical app control features and support the same ecosystem of smart accessories for added functionality.
Build Quality, Weather Resistance, and Durability
The WR147 and WR155 share a solid weather-resistant design with sealed internal components, enabling mowing in damp conditions and rain. Both include built-in rain sensors that automatically pause mowing and return the mower to the charging base when precipitation is detected, protecting your turf from clumping and damage.
Each mower also features rubberized wheels for grip, a low-profile body for easy access under shrubs, and a rugged plastic exterior to withstand UV exposure, dirt, and daily wear.
Winner: Tie
Each mower provides reliable durability and all-weather operation suitable for seasonal mowing cycles.
Noise Level and Residential Comfort
Both the WR147 and WR155 operate at a quiet 67 dB(A), which is significantly lower than traditional gas mowers. This allows either model to run during early mornings or late evenings without disturbing neighbors or family members.
Because the WR155 has a more powerful motor and wider deck, there may be a marginal increase in pitch during heavy grass loads, but the overall acoustic performance remains comparable.
Winner: Tie
Both mowers are equally quiet and ideal for noise-sensitive environments.
Installation Process and Boundary Setup
Installation for both the WR147 and WR155 includes laying a perimeter wire to define the mowing zone. This process is similar between models, although the WR155 ships with additional boundary wire and stakes to accommodate its greater coverage area. Setup may take 1–2 hours for smaller properties and longer for complex lawns.
After initial setup, both mowers require minimal maintenance beyond blade replacement every couple of months and routine cleaning of the wheels and underside deck.
Winner: Tie
Both models offer a straightforward DIY installation and are backed by Worx’s support for guides and video tutorials.
