Differences Worx WR140 vs Worx WR147
Below is a summary of the specifications:
Lawn Coverage Capability and Real-World Performance
Both models are purpose-built for lawns up to 1/4 acre, which makes them suitable for standard residential lots. The Worx WR140 is the earlier version, and while it still performs capably across various lawn layouts, the Worx WR147 introduces refined mowing logic and a slightly wider cutting deck.
The WR147’s 8-inch blade offers a key advantage: it allows for broader mowing passes, minimizing the number of rotations required to cover the entire lawn. This improves efficiency, especially in wider or rectangular lawns where fewer overlapping paths are needed.
Winner: Worx WR147
Its wider deck enables quicker coverage with fewer cycles, saving time and reducing wear on components.
Battery Power and Runtime Consistency
Both robotic mowers come with the Worx 20V 4.0Ah Power Share battery, compatible with other Worx cordless tools. Each unit delivers up to 90 minutes of runtime per charge, with a consistent 75-minute recharge cycle. This makes both highly capable of completing an entire mowing session on a single charge in most cases.
In terms of energy management, both models perform equally well thanks to their intelligent mowing algorithms, which help conserve power by avoiding unnecessary overlaps.
Winner: Tie
They offer identical runtime, battery compatibility, and recharge performance.
Cutting Deck, Height Adjustability, and Blade System
The biggest difference in cutting performance lies in the deck width. The WR140 features a 7-inch deck, while the WR147 expands this to 8 inches, translating to faster mowing times on large open areas.
Both offer cutting height adjustments between 1.5 and 3.5 inches, controlled via a manual dial on the mower. This flexibility allows users to fine-tune grass length for seasonal changes or aesthetic preference.
The cutting system in both mowers is based on a three-blade rotating disc, which mulches finely and evenly across the yard.
Winner: Worx WR147
The wider blade improves pass efficiency, particularly on flat or open lawns.
Each model incorporates the AIA™ (Artificial Intelligence Algorithm) navigation system developed by Worx. This technology allows for intelligent path planning that excels in narrow corridors and complicated mowing zones. Unlike random-pattern robotic mowers, both the WR140 and WR147 move predictably and efficiently.
Both models handle slopes up to 20° (35%), a capability that covers most real-world suburban lawns with gentle inclines, bumps, or uneven terrain. The large rear wheels provide adequate grip, while the compact design enables maneuvering in tight areas.
Winner: Tie
Both deliver smart, adaptive mowing behavior with excellent slope and obstacle performance.
Smart Features and Connectivity with the Landroid App
The Worx Landroid app, available on Android and iOS, gives full control over both the WR140 and WR147. Through the app, users can:
- Start or stop mowing
- Set or edit mowing schedules
- Track mower status and location
- Adjust blade height settings
- Update firmware remotely
The app-based control eliminates the need to physically access the mower each time, allowing for hands-free operation from anywhere with an internet connection. Both mowers support Wi-Fi pairing and communicate seamlessly once linked to the base station.
Each model is also compatible with a suite of modular add-ons:
Off-Limits Virtual Fence – Establish digital no-mow zones without running perimeter wire
Anti-Collision System (ACS) – Adds ultrasonic sensors to avoid physical contact with obstacles
Find My Landroid (GPS Module) – Provides anti-theft tracking and remote location monitoring
Winner: Tie
They are equal in smart feature capabilities, app integration, and modular customization.
Durability, Weather Resistance, and Seasonal Usage
Both the WR140 and WR147 are built with weather-resistant plastic housings, sealed against dust, debris, and light moisture. Each unit includes a rain sensor that automatically sends the mower back to the base when rain is detected, preventing grass clumping or blade corrosion.
They are intended for seasonal use in spring, summer, and fall, depending on your climate, and can be safely stored in winter. Regular cleaning of the wheels and deck ensures long-term performance.
Winner: Tie
Equal in durability, construction, and resistance to environmental conditions.
Noise Output and Residential Use
Operating at just 67 dB(A), both robotic mowers are significantly quieter than gas-powered alternatives. They can mow early in the morning or late in the evening without disturbing neighbors, making them perfect for communities with noise ordinances or HOA restrictions.
Their near-silent operation also allows for flexible mowing schedules, especially useful when paired with automated routines in the app.
Winner: Tie
Both provide ultra-quiet operation ideal for residential settings.
Installation, Accessories, and Ease of Setup
The installation process for the WR140 and WR147 is virtually identical. Users must lay a perimeter wire to define the mowing area, connect the charging base to a power source, and pair the mower to the mobile app.
Worx includes all necessary setup components in the box: wire, stakes, base, charger, blades, and user manual. Both models support firmware updates via Wi-Fi, ensuring they remain compatible with future app updates and add-ons.
Winner: Tie
Equal in installation time, included accessories, and upgrade readiness.
