Worx Landroid S 20V

Name: Worx Landroid S 20V
Brand: Worx

Simplest entry point to robotic lawn care, rated for 1/8 acre. The perimeter wire is the trade-off for predictable behavior, and it ships in the box with the pegs to hold it down. The machine returns to its base and charges on its own; the recurring owner task is checking the wire, not tending the mower.

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 AutonomyCopes with everyday clutter and frees itself, shown by independent testing.
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 S 20V runs preset routines on its own, and the owner is its recovery system.

Navigation and control

Perimeter-wire guided with gyroscope-based traction control and randomized path within boundary.
Why this level
- Wire-guided randomized mowing path with no end-to-end task planning.
- Mower does not map the yard or plan efficient routes; it operates under boundary constraint only.
- This meets Level II (Assisted Autonomy) criteria, requiring infrastructure setup and periodic human oversight but enabling scheduled operation within defined zones.

Capability40% of the score52What it does without you.

Task completion16% of the score64

Evidence

Within its 1/8 acre rating it runs unattended once the wire is pegged, returning to the base when the pack runs down and resuming when it has charged, which covers the self-service leg. Held down by two routine human closures the record documents: owners report at least one wire repair per season, and each one stops autonomy until it is spliced, and turf over about 3 cm defeats it, so an overgrown lawn has to be pre-mowed by hand before the robot can take it back.

Coverage and navigation10% of the score48

Evidence

A randomized path within the boundary, with the record stating outright that the mower does not map the yard, does not plan efficient routes, and operates under boundary constraint only. Full coverage is achievable because 1/8 acre is small enough for a random walk to close over a 90 minute run, which is the anchor's completion-by-run-time state exactly, and nothing is retained or reported.

Edge-case recovery10% of the score43

Evidence

On losing the wire signal it stops and stays stopped rather than continuing to cut or leaving the property, which is a clean halt, and the Landroid platform's siblings document a named error code and an app alert for the same condition. Held below the anchor because this record documents no reporting of its own, and because it documents a second condition with no recovery at all: wheel slippage and failed docking on inclines above 12 to 15 degrees, resolved by hand.

Operating envelope4% of the score40

Evidence

The narrowest envelope of the nine mowers, and narrow on every axis this referent names. Area is 1/8 acre, 5,445 sq ft, the smallest tier in the line and not extendable by more sessions. Slopes are safe under 15 degrees with slippage and docking failures reported from 12 upward, wet grass costs traction, and turf over 3 cm defeats it. The record's own words are that the design baseline is dry, level yards with standard grass.

Dependability40% of the score83Whether it keeps doing it.

Field failure rate16% of the score70

Evidence

At the recurring-mode anchor, and unusually the number rests on real evidence rather than its absence: 100-plus owner reports spanning 2021 to 2026 marked complete, twelve press reviews and a complete longitudinal source, with no recall in five years. What that evidence shows is a mode, boundary wire failure from debris cuts, wet-mulch corrosion and foot traffic, at roughly one repair per season, which stops autonomy each time and is fixed with a $15 to $25 kit. External in cause and cheap to remedy, but annual.

Software stability14% of the score90

Evidence

The strongest software position among these mowers. Updates ship and are documented, with a firmware source pointing at Worx app release notes across multiple updates, and the owner body that would surface a regression is large and long, 100-plus reports across 2021 to 2026 marked complete, with no regression pattern in it. Short of the twelve-month no-regression anchor only because that silence is inferred from a large record rather than affirmatively stated by owners, and the notes are not shown to be inspectable per release.

Support longevity10% of the score94

Evidence

The best support position of the nine, and it is priced end to end rather than promised. Blades are first-party and cheap, a WA0190 twelve-pack with screws under $15 or the Long-Life WA0789 at $29.99; 820 ft of wire and 340 pegs ship in the box with repair kits at $15 to $25; the pack is a removable 20V Power Share unit shared across the Worx tool line rather than a proprietary cell; and the model has been stocked at Amazon, Lowe's and direct for five years with documented warranty coverage.

Ownership burden20% of the score81What it asks of you.

Routine maintenance12% of the score75

Evidence

Light for this category. There is no per-run handling, no fixed blade interval, and the boundary wire stays pegged through the winter rather than being lifted. The recurring work is a weekly base alignment and charging-contact check, a monthly walk of the wire looking for cuts, displacement and corrosion, a spring wire audit, and bringing the mower and its pack indoors in the fall. Pre-mowing an overgrown lawn by hand is the one heavy step.

Consumables8% of the score89

Evidence

A low and well-documented running cost. Blades are sold twelve to a kit for under $15 with no hour-based interval, replaced as a set when cutting quality drops, so a season costs a few dollars. The boundary wire and its 340 pegs came in the box and repair kits are $15 to $25 against roughly one break a season. The battery is a commodity Worx 20V Power Share pack rather than a service part.

OWNERSHIP

Living with it.

Mature platform with broad owner base and proven seven-year track record. Dock docking remains inconsistent; wire durability is the dominant failure point.

Thousands of units in long-term consumer hands. Firmware updates since 2019 show steady refinement of dock-interaction and boundary-detection; no major failures or recalls documented. Owner reports cite wire integrity and dock alignment as primary maintenance drivers.

Common questions

What people actually ask.

5 answered

OwnershipHow much does boundary-wire installation cost and how long does it take?

There is no wire to buy. Worx ships the WR165 with 820 ft of boundary wire and 340 pegs, more than a 5,445 sq ft yard needs. The documented method is to peg the wire down at the surface along the perimeter, where the grass grows over it within a couple of weeks. Plan on walking and pegging the perimeter rather than digging; the time scales with how many beds, trees and islands the loop has to route around.

OperationWhat happens if the Worx Landroid S cuts through the perimeter wire?

The mower stops and no longer operates autonomously until you repair the break. Manufacturer recommends visual inspection monthly and suggests repair kits (USD 15-25) for common break points near obstacles.

OperationCan the Landroid S operate in wet or heavily overgrown yards?

Manufacturer specs list safe operation on slopes under 15 degrees; wet grass reduces traction. Owner reports document poor performance on overgrown turf (>3 cm height) and recommend pre-mowing if grass gets tall.

OperationWhat is the battery runtime and does it handle charging docks?

Runtime reaches 90 minutes on a full charge. The Landroid returns to its charging base on its own when the pack runs down and resumes when it has charged. The 20V Power Share pack is removable and can be charged off the machine, but that is not the normal operating path.

OwnershipHow often do blades need replacement and what is the annual cost?

The Landroid cuts with a floating disc carrying three blades, and Worx sells them in multi-packs rather than pairs. The standard WA0190 kit is 12 blades with screws for under $15, and the Long-Life set (WA0789) is $29.99. Worx does not publish an hour-based replacement interval; replace the blades when cutting quality drops or a blade is chipped, and replace all three at once so the disc stays balanced.
