Gardena Sileno Minimo vs Worx Landroid S for tiny urban lawns

Choosing between the Gardena Sileno Minimo vs Worx Landroid S for a tiny urban lawn comes down to three things: how quietly the mower runs in a dense neighborhood, how cleanly it edges around brick borders and patio stones, and how forgiving the setup feels when your "lawn" is really just 200–250 square meters wedged between a fence and the driveway. The Sileno Minimo wins on whisper-quiet operation and an almost invisible aesthetic; the Landroid S wins on hackability, a deeper app ecosystem, and a friendlier price tag. Below is the side-by-side, the install reality, and which one I would put on a 200 m² courtyard in 2026.

Quick verdict for sub-250 m² city lawns

If your priority is silent, set-and-forget operation under a bedroom window, the Gardena Sileno Minimo is the easier recommendation. It is the quietest mower in this size class and Gardena's SensorCut navigation handles narrow passages and irregular shapes without much fuss. If you want a cheaper mower you can tinker with, that integrates with Alexa and Google Assistant out of the box, and that you can expand with add-on modules (anti-collision ultrasonic sensor, off-limits radio beacon, voice control), the Worx Landroid S is the better buy.

Both are designed for lawns up to roughly 250–300 m², both use a perimeter boundary wire, and both are realistically priced at well under a thousand dollars when you catch them on sale. Neither is the right answer for a hilly suburban half-acre — for that, our large yard roundup covers the right tier of machine.

Side-by-side: Gardena Sileno Minimo vs Worx Landroid S specs

That spec table is the headline of the Gardena Sileno Minimo vs Worx Landroid S comparison, but the numbers do not capture how the two mowers behave on a real city plot. The next sections do.

Cutting performance on a 200 m² city plot

Tiny urban lawns punish robots in ways big suburban lawns do not. They tend to be long and narrow, full of furniture legs and planter corners, and bordered by hard edges that the mower has to graze without scraping. Both machines use a random walking algorithm rather than systematic line mowing, which is fine on small lawns because the mower runs over every patch many times per week.

The Sileno Minimo's SensorCut logic is noticeably better at handling corridors — the strip of grass between a fence and a path that is barely wider than the mower. It enters, mows, and exits without spinning in circles. The Landroid S in stock form is more likely to wander, retreat, and re-enter several times, which is fine but adds runtime. Worx sells a Cut to Edge module that helps the Landroid trace one boundary cleanly on the way home; without it you will still have a 6–7 cm uncut strip along the wire that you need to trim manually every few weeks.

On cut quality, both deliver the fine mulched clippings that make robot mowers worth owning in the first place. The Landroid's 18 cm deck is slightly faster per pass; the Sileno's 16 cm deck pivots more tightly around obstacles. On a typical 200 m² lawn the daily runtime difference is under 20 minutes either way.

Noise and neighbor friendliness

This is where the Gardena pulls ahead decisively for urban use. At a measured 57 dB(A) the Sileno Minimo is closer to a quiet refrigerator than a lawn mower; you can run it through the night without anyone complaining. The Landroid S at 62 dB(A) is still quieter than any gas mower, but a neighbor sitting two meters away on the other side of a fence will notice it. If your lawn is overlooked by apartment balconies or shares a wall with a townhouse, the extra 5 dB matters more than the spec sheet suggests — 5 dB is roughly half the perceived loudness.

Both machines have a quiet-hours scheduler in their apps, so you can restrict operation to daylight only if you prefer. But if you actively want a mower that runs at 6 a.m. so the lawn is dry by breakfast, the Sileno is the one you can do that with.

Installation in a courtyard or shared driveway

Both mowers require a perimeter wire pinned around the edge of the lawn and around any flower beds or trees you want excluded. On a 200 m² rectangle that is a Saturday morning job, including setting the charging base. Our step-by-step install guide walks through wire spacing, corner geometry, and the common rookie mistakes.

The Sileno Minimo comes with 150 m of wire and 200 pegs, which is enough for most courtyards. The Landroid S ships with 100 m of wire and 130 pegs, and you may need a small spool of extension wire if your plot has a lot of internal islands. Both can also be installed with the wire buried 5–10 cm under the turf, which is the option I prefer in a high-traffic urban space where surface wire will get caught by kids or pets.

One urban-specific factor: shared driveways and gated alleys. Neither mower can cross paving stones unless you bury the wire under the slab in a short conduit, which is doable but messy. If your lawn is split into two zones by a path, the Landroid S handles multi-zone scheduling in the app more gracefully than the Sileno Minimo, which is more of a single-zone tool.

App, smarts, and theft protection in a city setting

The Worx Landroid app is the better piece of software in 2026. It has Wi-Fi as standard, supports Alexa and Google Assistant voice commands without any extra gateway, surfaces weather-based scheduling automatically, and lets you bolt on extras like the Find My Landroid GPS module — genuinely useful on a front lawn that opens onto a public sidewalk. The mower itself has a PIN and alarm, but GPS turns a stolen Landroid into a recoverable Landroid.

The Gardena Bluetooth app is solid for basic scheduling and adjusting cutting height, but it tops out at Bluetooth range unless you also buy the Gardena smart Gateway and a smart Sileno bundle. For a tiny lawn where you stand next to the mower to start it anyway, that is fine; for anyone who wants to check the mower from the office, the Landroid is the friendlier daily driver.

Both machines have lift sensors, tilt sensors, and audible alarms. Both will refuse to run for a stranger who does not know the PIN. Neither is a bank vault — if you live somewhere with frequent garden theft, GPS on the Landroid is worth the upgrade.

Price, warranty, and ten-year ownership math

Street prices in 2026 have settled to roughly $700–$850 for the Sileno Minimo 250 and $550–$700 for the Landroid S, with the Landroid usually $100–$150 cheaper for an equivalent lawn size. Replacement blades are a few dollars on either platform and should be swapped every two to three months in the growing season. Battery replacements after year three or four are the next big cost item; Gardena uses a sealed internal pack that requires a service visit, while the Landroid takes a user-swappable 20V Power Share battery that you can buy off the shelf at any hardware store. Over a five-to-seven-year ownership horizon that battery accessibility tilts the running-cost math toward Worx.

Warranties are two years on both, with a 10-year availability promise on Gardena spare parts that I have personally tested on an older Sileno City and found honored.

Who should buy the Gardena Sileno Minimo

Pick the Sileno Minimo if your lawn is under 250 m², hemmed in by neighbors or windows, and you want the mower to disappear into the routine of the house. It is the quieter machine, the more polished out-of-the-box experience, and the one with the better corridor navigation. If you already own other Gardena smart garden products, the ecosystem case is even stronger. Our deeper look at the sibling model is in the Gardena Sileno City review, which shares the same SensorCut platform.

Who should buy the Worx Landroid S

Pick the Landroid S if you want native Wi-Fi and voice control, a lower sticker price, and a platform you can expand with modules over time. It is the better choice for split-zone lawns, for renters who may need to move the system to a new property, and for anyone whose front lawn is exposed enough to justify the GPS add-on. If you eventually upsize the lawn, Worx makes a clear step-up path — we cover the bigger sibling in the Worx Landroid M WR140 review.

Which one should you buy?

For most readers landing on this Gardena Sileno Minimo vs Worx Landroid S comparison with a true urban courtyard or front-yard postage stamp, the Sileno Minimo is the mower I would put down money on. It is quieter, calmer in tight spaces, and the one you forget is even running. The Landroid S is the better value and the better tinker-toy, and for a slightly larger or more complicated lawn it pulls ahead. For broader options at this size class, the best robot mowers for small yards guide is the natural next read.

Frequently Asked Questions

Is the Gardena Sileno Minimo or Worx Landroid S quieter for a townhouse?

The Sileno Minimo measures around 57 dB(A) versus 62 dB(A) for the Landroid S. That five-decibel gap is roughly half the perceived loudness, which is significant when a neighbor's bedroom window is a few meters from your lawn. For shared-wall townhouses, the Sileno Minimo is the clearly better choice.

Can either mower handle a 300 m² urban lawn without a boundary wire?

No. Both the Sileno Minimo and the Landroid S require a perimeter boundary wire pegged or buried around the lawn. Wire-free RTK and vision mowers exist for this size class in 2026, but they sit a tier above in price. If you want to skip the wire entirely, our wire-free robot mower roundup covers the current options.

How long does the Worx Landroid S take to mow 200 m²?

On a full charge the Landroid S mows for about 60 minutes and covers roughly 150–180 m² before returning to charge. For a 200 m² lawn it will complete one full pass in two charge cycles, or roughly two and a half to three hours of elapsed time including the recharge break.

Does the Gardena Sileno Minimo work with Alexa or Google Home?

Only indirectly. The Sileno Minimo is Bluetooth-only by default. To get Alexa or Google Assistant control you need to add Gardena's smart Gateway and a compatible smart hub bundle. The Worx Landroid S, by contrast, includes Wi-Fi and supports both voice assistants natively with no extra hardware.

Which mower handles a slight slope better on a city front lawn?

The Sileno Minimo is rated to 25% slope (about 14 degrees) versus 20% (about 11 degrees) for the Landroid S. On a typical urban front lawn with a gentle grade down to the sidewalk, both will manage comfortably; only the steepest small lawns will expose the difference. For genuine slopes see our hills and slopes guide.

How often will I need to replace the blades on either mower?

Both mowers use small pivoting razor blades that should be swapped every 2–3 months during the growing season, or whenever you notice the grass tips look ragged rather than cleanly sheared. Replacement blade packs cost a few dollars and the swap takes under five minutes with a Phillips screwdriver.

Will a robot mower work on a lawn with a lot of moss or shade?

Yes, with caveats. Both the Sileno Minimo and the Landroid S will physically mow a mossy or shaded lawn without issue, but neither will fix the underlying turf health problem. Frequent cutting actually helps the grass compete with moss over a season. If the lawn is so shaded it is mostly moss, address the shade first; the mower is not a substitute for soil work.
