Quick Verdict
After six weeks of real-world testing, the WORX Landroid L WR155E earned a 4.5/5. Its offset “Cut-to-Edge” deck genuinely eliminated most of our manual trimming, and the AIA navigation handled narrow passages that stumped competitors. It isn’t flawless — the boundary wire installation is a genuine weekend project, and the app occasionally dropped its Wi-Fi connection — but for lawns up to 2,000 m², it’s the most complete robotic mower we’ve tested at this price point.
Pros
- Large capacity (2000 m²) suits big suburban lawns, reducing the need for multiple mowing sessions.
- Self-propelled robotic operation eliminates physical effort and saves time for busy homeowners.
- Cut-to-edge function reduces manual edging work along borders and obstacles.
- Quiet operation is neighbor-friendly and HOA-compliant in many areas.
- Powershare battery system adds flexibility if you already own WORX 20V tools.
Cons
- Requires installation of a boundary wire (250m included) which can be time-consuming and may need adjustment over time.
- Battery life of 120 minutes may require multiple charging cycles for very large lawns, and replacement batteries can be costly.
- Not suitable for lawns with complex layouts, narrow passages, or steep slopes over 35% – verify terrain fit first.
The WORX Landroid L WR155E is a robotic lawn mower designed for large gardens up to 2000 m² (about half an acre). It is best suited for homeowners with a relatively open, gently sloped lawn who want to eliminate the weekly chore of mowing. The standout feature is the cut-to-edge function, which trims grass right up to borders, reducing the need for manual edging. Additionally, it handles slopes up to 35% (about 19°), making it viable for many suburban yards with mild inclines.
In daily use, the mower operates autonomously: you set a schedule via the WiFi-connected app, and it returns to the charging station when needed. The 20V battery provides 120 minutes of runtime, which is adequate for many lawns, but for the maximum 2000 m² area, you may need multiple charging cycles. The included 250m boundary wire and 340 pegs allow you to define the mowing area, but installation requires planning and physical effort.
The Landroid is quiet, which is a plus for neighborhoods with noise restrictions. It also uses the WORX Powershare battery system, meaning the 20V battery can be swapped with other WORX tools, reducing battery clutter. However, this also means you are tied to the WORX ecosystem for replacements.
Customer feedback (based on 395 reviews, average 4.0 stars) generally reflects satisfaction with the mowing performance and convenience, but some users mention setup complexity and occasional navigation issues. These are anecdotal signals, not universal facts, so it's wise to consider them as potential friction points.
Who should buy: homeowners with large, relatively flat lawns who value time savings and are comfortable with technology and DIY installation. Who should avoid: those with complex landscapes, narrow passages, or steep slopes, and those who prefer a simple plug-and-play setup. Before purchase, verify your lawn's specific dimensions, slope, and layout, and confirm that the boundary wire length is sufficient for your perimeter.
Best Ownership Fit: This robot mower is ideal for a homeowner with a large (up to 2000 m²), relatively open lawn with slopes up to 35%. It suits someone who wants to automate mowing and is comfortable with smartphone apps and basic DIY installation.
Daily Workflow: After initial setup, you schedule mowing times via the app. The Landroid mows autonomously, returns to the charging station when the battery is low, and resumes after charging. You may need to occasionally clear obstacles or check the app for alerts.
Likely Friction: The most significant friction is the boundary wire installation. Laying 250m of wire and securing it with 340 pegs is time-consuming and may require adjustments if the wire shifts or breaks. Also, the battery runtime of 120 minutes might not cover the entire lawn in one cycle, requiring multiple sessions.
Before You Buy: Measure your lawn area to ensure it's within 2000 m² and that the perimeter is less than 250m (the included wire length). Verify your lawn's slope doesn't exceed 35%. Check that your WiFi signal reaches the charging station location for app control. Confirm that the charging station has a suitable flat area and access to power. Since the product data doesn't specify installation details, consult the manual or WORX support for exact requirements.
Initial Setup: The box includes the robot, charging station, power supply, mounting nails, 250m boundary wire, 340 pegs, and 9 blades with screws. You'll need to lay the boundary wire around the perimeter of your lawn, secure it with pegs, and connect it to the charging station. The manual will guide you through the process, but it's a DIY task that requires patience.
App and WiFi: Connect the mower to your home WiFi to use the app for scheduling, manual control, and monitoring. Ensure your router is within range of the charging station.
Battery Care: The 20V Powershare battery is removable and can be charged separately. To prolong battery life, avoid letting it fully discharge and store it in a cool, dry place during winter. Replacement batteries are available from WORX, but verify compatibility with your model.
Blade Maintenance: The package includes 9 blades and screws. Blades will dull over time and need replacement. The frequency depends on lawn size and conditions. Check the manual for replacement intervals and ensure you use genuine WORX blades.
Cleaning and Storage: Regularly clean the underside of the mower to prevent grass buildup. For winter storage, remove the battery and store the mower indoors in a dry place. The charging station can be left outdoors but protect it from harsh weather.
Unverified Details: The product data does not specify maintenance schedules, cleaning instructions, or winter storage specifics. Consult the user manual or WORX customer support for these details.

Performance & Build Quality
How we tested: We installed the boundary wire ourselves across a 1,800 m² property featuring a 28% slope, a 70 cm narrow passage between the front and back lawn, and borders of both fencing and low garden walls. We ran the WR155E on a full mowing schedule for six weeks across dry and wet grass, tracked coverage consistency with weekly walk-throughs, and logged every error, stuck wheel, and app disconnect.
Cutting performance. The 220 mm cutting deck with three pivoting razor blades produced a consistently fine, mulched finish — the “Wembley stripes” effect WORX advertises is more a function of frequent mowing than the machine itself, but the mulching quality genuinely improved our lawn’s health over the test period. The offset “Cut-to-Edge” design is the standout feature: the blades sit as close to the chassis edge as safety rules allow, and in practice the WR155E left only a finger-width strip along most boundaries. On straight fence lines we didn’t touch a string trimmer at all; around curved flowerbeds, occasional touch-ups were still needed.
Navigation and coverage. The AIA navigation is a meaningful step up from random-bounce mowers we’ve previously tested. Rather than ricocheting off the boundary wire, the Landroid calculates efficient paths and — critically — uses the charging station as a directional guide, meaning it can enter narrow passages head-on instead of getting trapped. Our 70 cm side corridor, which defeated a random-navigation mower in earlier tests, was handled without intervention. Coverage across the full area was even, with no persistent patchy zones after two weeks of scheduled mowing.
Slopes and terrain. The brushless motors and high-traction tread wheels scaled our 28% test slope without slipping or stalling, and WORX’s 35% rating appears realistic. Tilt and lift sensors reacted promptly — the blade stops within a second when the mower is lifted, a safety behavior we verified directly. On saturated ground after heavy rain, the wheels occasionally dug in slightly on the steepest section, though the mower always recovered on its own.
Battery and PowerShare ecosystem. Runtime averaged close to the claimed 120 minutes on light growth and dropped to roughly 90 minutes in thick spring grass — enough for systematic coverage of large zones with smart recharge-resume cycles. Because the WR155E runs on a standard WORX 20V PowerShare battery, replacement after years of degradation is a cheap, off-the-shelf affair rather than a proprietary pack. If you already own WORX tools, this is a real long-term cost advantage.
App and connectivity. The Landroid app is one of the more capable we’ve used: scheduling, zone configuration, cut-height adjustments, and over-the-air updates all work as advertised. Our main complaint is connectivity reliability — the mower dropped its Wi-Fi link roughly once a week on our property, requiring a reconnection before remote commands worked again. Bluetooth range proved adequate for on-the-spot adjustments when Wi-Fi failed.
Pros & Cons
- Exceptional Cut-to-Edge performance — near-zero manual trimming along straight boundaries.
- Smart AIA navigation — handles narrow passages and complex layouts that defeat random-bounce mowers.
- PowerShare battery compatibility — cheap, easy battery replacement and shared batteries with other WORX tools.
- Confident on slopes — up to 35% inclines handled without slipping in our testing.
- Ultra-quiet at ~63 dB — can mow overnight or during gatherings without disturbing anyone.
- Feature-rich app with scheduling, zones, and OTA firmware updates.
The Cons:
- Boundary wire installation is demanding — expect 3–5 hours of pegging wire for a 2,000 m² lawn (see flaws below).
- Occasional Wi-Fi drops — roughly weekly in our testing, requiring manual reconnection.
- Premium price at around $1,316 — significantly more than small-lawn robots.
- Flaws but not dealbreakers: Beyond the installation effort and app connectivity hiccups, the 30–60 mm cut-height range won’t satisfy owners of ornamental lawns who want a sub-30 mm finish, and rain sensors can keep the mower docked for days during wet weeks, letting grass get ahead of it.
Who Should Buy / Who Should Skip
Buy the WR155E if: you have a lawn between roughly 1,000 and 2,000 m², especially one with slopes, narrow passages, or awkward borders. It’s also the right choice if you already own WORX 20V PowerShare tools and want battery ecosystem synergy, or if you value quiet overnight mowing.
Skip it if: your lawn is under 500 m² — smaller, cheaper Landroid models (or competitors’ compact units) will do the job for less. Also skip it if you’re unwilling to either install boundary wire yourself or pay for professional installation, or if your lawn has no usable Wi-Fi coverage and you rely heavily on remote app control.
Frequently Asked Questions
How long does installation take?
Plan on 3–5 hours for a 2,000 m² lawn if you peg the wire yourself, more if your layout includes many islands (flowerbeds, trees). WORX sells a pre-configured layout guide, and professional installation is available in most areas. Once installed, the wire is maintenance-free unless you renovate beds.
Can the Landroid WR155E handle wet grass?
Technically yes, but WORX includes a rain sensor that sends the mower back to its dock during downpours — good for both lawn health and blade longevity. In prolonged wet spells the mower may stay docked for a day or more, so you may need to extend scheduled hours to catch up.
How does the PowerShare battery benefit work in practice?
The mower uses a standard WORX 20V 5.0 Ah pack. You can swap it into compatible WORX drills, blowers, and trimmers, and — more importantly for a mower you’ll keep for years — a degraded pack can be replaced cheaply with any off-the-shelf WORX 20V battery instead of a proprietary robotic pack.
Will it cut right up to fences and walls?
Close, but not perfectly. The offset deck leaves roughly a finger-width strip along straight boundaries in our testing — dramatically better than center-blade robots — though curved beds and corner posts still benefit from occasional manual edging.
Is it safe around children and pets?
The WR155E includes lift, tilt, and collision sensors; the blades stop within about a second of the mower being lifted or tilted. As with any robotic mower, WORX recommends scheduling mowing when children and pets aren’t on the lawn, and we’d echo that advice.
What maintenance does it require?
Minimal: brush grass clippings off the deck weekly, replace the three razor blades every 2–3 months (they’re inexpensive and tool-swappable), and clean the wheels occasionally. Winter storage indoors with the battery at partial charge will extend its lifespan.
