Worx Landroid L 20V WR155

Name: Worx Landroid L 20V WR155
Brand: Worx

A smartphone-connected wire-guided mower that bridges early autonomous designs and modern app expectations. The appeal depends entirely on whether the buyer already has boundary-wire infrastructure or is willing to install it.

Autonomy Ladder

Why Level II.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyHandles new obstacles and re-plans in real time; rare in consumer products.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Worx Landroid L 20V WR155 runs preset routines on its own, and the owner is its recovery system.

Navigation and control
Boundary wire perimeter guidance with AIA path planning for systematic patterns and narrow passages, contact-based obstacle detection, and app-based scheduling
Why this level
- Boundary-wire navigation with app-based scheduling qualifies as Level II (Assisted Autonomy).
- The robot executes autonomous cutting within the wire perimeter and returns to its base to charge, but it relies on manual wire installation, on being carried back inside if it escapes the boundary, and on human judgment about cutting patterns.
- AIA is path planning rather than sensing, and obstacle handling as shipped is contact-based.
- Smartphone control does not elevate autonomy level; it adds convenience.

Capability40% of the score61What it does without you.

Task completion16% of the score75

Evidence

Testbericht.de's owner test of the WR155E (the European build of the Landroid L 20V) reports that once the interference sources were cleared "läuft er jedoch einwandfrei und schafft das gesamte Grundstück von 2000qm in nur drei Tagen" (it runs flawlessly and does the whole 2000 square meter property in just three days), and a follow-up after three weeks confirms it "zuverlässig und gründlich arbeitet" (works reliably and thoroughly).

Coverage and navigation10% of the score55

Evidence

Antti Koskela's owner review of the WR155E explains that the machine carries no map: "the zones will obviously be off, they are defined by measuring the distance traveled from the base station, not using GPS", and the robot "doesn't really care about the lot it's dropped on". He also notes the finished result is good but "it takes a while to get there. A long while, to be precise", which is coverage established by run time inside the wire rather than a retained plan.

Edge-case recovery10% of the score50

Evidence

Testbericht.de's owner reports the Landroid "blieb oft hängen, besonders an Stellen mit Rindenmulch und Rasenkantensteinen" (often got stuck, especially at bark mulch and lawn edging stones), and that the fix was removing those features from the garden, not the robot recovering. A commenter on Koskila's review describes the same handling: "if the robot is stuck, belly up or whatever, there is no emergency to fix it, I'll do it when I'm going outside for some fresh air."

Operating envelope4% of the score52

Evidence

In the roboter-forum.com WR155E thread, owner Djub describes what his roughly 1800 square meter garden needs: the entire existing boundary wire lifted and relaid because the Landroid needs only about 26 cm of edge clearance, plus the ACS module to detect trees, sandbox, above-ground pool, swing and playhouse, and OffLimit magnetic strip to fence beds, bushes and the trampoline. The work area has to be wired and, for anything short of 20 cm tall, physically fenced before the machine can be left in it.

Dependability40% of the score76Whether it keeps doing it.

Field failure rate16% of the score81

Evidence

Scored on the Landroid platform rather than the SKU, which is fair here: same chassis, same wire architecture, same 20V pack family and same blade disc as the seven-year Landroid M record, with no recall anywhere on the line. Held below that sibling's own figure because this record's evidence is genuinely thin and admits it, with no press-review, firmware or longitudinal source, no failure-mode section, and the skip_for entry conceding that long-term failure data and third-party analysis remain sparse.

Software stability14% of the score65

Evidence

The ordinary consumer-robot case. The machine is app-connected with remote scheduling and alerts on a platform Worx maintains firmware for, so updates ship, and no regression pattern is reported across five years in market. There is no firmware source in this record, no release notes cited and no independent record of update behavior. Silence in both directions.

Support longevity10% of the score85

Evidence

The Landroid platform position, which is strong: five years in continuous retail distribution, first-party blades stocked and priced at $15 to $30, wire repair kits available, and add-on modules still sold for the model. Held below its siblings here because this record does not name the battery pack or its price, so the item that ends a cordless machine's life is undocumented, and no support window is published.

Ownership burden20% of the score56What it asks of you.

Routine maintenance12% of the score59

Evidence

The most demanding routine of the wire mowers here. Weekly means inspecting the boundary wire for breaks and clearing the blade deck and motor area; blades come off every four to six weeks; monthly means cleaning dock contacts with fine grit and, per the record, verifying a successful dock connection after each mowing cycle. Seasonally the wire is continuity-tested with a multimeter, and annually the Wi-Fi range is checked and the dock relocated if the app connection is intermittent.

Consumables8% of the score51

Evidence

The heaviest blade cadence among the mowers here: replacement every four to six weeks at $15 to $30 a pair, which runs to $130 or more a season on a machine selling near $799, against siblings on the same platform that change blades when quality drops and buy them twelve to a kit. Wire repair kits add to it. The obstacle-avoidance module is a further purchase, and it buys a capability the base machine does not have rather than a spare part.

OWNERSHIP

Living with it.

App connectivity is stable on modern networks; wire-guidance system is straightforward; consumable-heavy due to frequent blade replacement and seasonal wire repairs.

No major recalls since 2019 launch. Owner-report forums document predictable wear patterns: blade dullness within 4-6 weeks, intermittent docking contact within 12 months, occasional Wi-Fi disconnection requiring app restart. Wire breaks are seasonal, not unit defects.

Common questions

What people actually ask.

5 answered

OperationDoes the Worx Landroid L WR155 require burying a boundary wire, or does it support virtual boundaries?

It requires a physical boundary wire. Virtual boundaries via app or GPS are not supported. The wire must be installed at the yard perimeter; installation typically takes 1-3 hours depending on property shape and size.

OwnershipWhat does the AIA technology do, and does it replace the need for boundary maintenance?

AIA stands for Artificial Intelligence Algorithm, and it is a path-planning feature. Worx describes it as letting the mower work through narrow passages and cut in systematic patterns rather than at random. It is not obstacle sensing. As shipped, the WR155 finds obstacles by bumping into them, and obstacle avoidance is one of Worx’s separately purchased add-on modules. AIA does not change the boundary wire’s role, which is still the only thing telling the machine where the property ends.

CompatibilityCan the WR155 be controlled entirely from a smartphone app, or does it need manual start buttons?

Either path works. The machine carries an onboard LCD and control dial, and scheduling and start/stop can be set from it without the app or an internet connection. The app adds remote scheduling, start/stop and alert notifications. The charging base still has to be positioned and powered, and the robot starts its cycles from it.

OperationWhat is the runtime, and how many charge cycles does a half-acre property require?

Runtime is approximately 90 minutes per charge. A half-acre property typically requires one to two full charge cycles depending on grass density and blade sharpness. The base is a fixed charging dock; the mower drives itself back to it, charges, and drives out again on its own.

OperationIf the WR155 crosses the boundary wire or gets stuck, what happens?

If it detects the wire signal, it stops and reverses. If it physically crosses and loses wire signal, it stops. Manual retrieval and repositioning inside the boundary is required. The app sends an alert, but the robot does not self-recover.
