What is the quietest robot lawn mower in 2026?

The lowest rating we track belongs to the Segway Navimow H1 series (H1500-VF), at no more than 54 dB(A) per Segway. But navimow.com lists the H1500-VF as sold out as of October 31, 2026, and its successor, the Navimow H2, is rated 60 dB(A) sound power in its manual. Of the mowers you can easily buy new, the Gardena Sileno Minimo is the quietest at 57 dB(A), per Gardena, and Husqvarna's residential Automower models and the wire-free Kress KR172 both run around 58–59 dB(A). All of them are dramatically quieter than a gas mower, which typically runs 90–100 dB(A).

How many decibels is a quiet robot lawn mower?

A quiet robot mower operates in the mid-50s to low-60s dB(A). The now sold-out Segway Navimow H1500-VF is rated at 54 dB(A) and the Gardena Sileno Minimo at 57 dB(A), per the manufacturers, while most Husqvarna Automower, Navimow X3 and the new Navimow H2 models sit around 58–60 dB(A). For reference, 54 dB(A) is around the level of a quiet office or light rain, and every 10 dB roughly doubles perceived loudness — so a 54 dB(A) mower sounds far softer than a 67 dB(A) one.

Are robot lawn mowers quiet enough to run at night?

Yes. Because the quietest models run at 54–60 dB(A) — comparable to a refrigerator or quiet conversation — many owners schedule them overnight or early morning without disturbing the household or neighbors. That said, some HOAs and local ordinances restrict powered-equipment hours, and RTK/GPS models still need clear sky view, so check your rules before setting an overnight schedule.

Why are robot mowers so much quieter than gas mowers?

Robot mowers use a small electric motor spinning lightweight razor-style blades at low power, rather than a combustion engine driving a large steel blade. That difference drops the noise from roughly 90–100 dB(A) for a gas push mower to about 54–67 dB(A) for a robot — a reduction of 30–40 dB, which is why they can run unattended without ear protection or annoying the neighborhood.

Is the Worx Landroid loud compared to other robot mowers?

The Worx Landroid is one of the louder robot mowers, rated around 67 dB(A) in its owner's manual — roughly 10–13 dB above the quietest Segway and Gardena models. It's still far quieter than any gas mower and fine for daytime use, but if silence is your priority, a wire-free Navimow or a Gardena Sileno will be noticeably softer.

Does a quieter robot mower cut worse?

No — noise and cut quality are largely independent. The quietest models here (Navimow, Gardena Sileno, Husqvarna Automower) are also among the best-cutting, because low noise comes from efficient electric drivetrains and small blades rather than any compromise in mowing. You choose quiet models for scheduling flexibility and neighbor-friendliness, not at the expense of a clean cut.

Quietest Robot Lawn Mower 2026: Lowest-Noise Picks by dB(A)

Quick Answer: The quietest robot lawn mower you can easily buy new in 2026 is the Gardena Sileno Minimo, rated at 57 dB(A) per Gardena, for small, tidy lawns. The lowest rating we track, 54 dB(A), belongs to the Segway Navimow H1 series (H1500-VF), but navimow.com lists it as sold out as of October 31, 2026, and its successor, the Navimow H2, is rated 60 dB(A) sound power in its manual. Husqvarna’s Automower residential models run about 58–59 dB(A). If you need quiet plus slopes or big acreage, the Segway Navimow i2 AWD (59 dB(A)) and Mammotion Luba AWD (under 60 dB(A)) stay whisper-quiet while climbing hills. Every one of these is 30–40 dB softer than a gas mower, so you can schedule them early morning or overnight without waking the street.

Noise is one of the best reasons to switch to a robot mower — and it’s often overlooked until a neighbor’s gas mower fires up at 8 a.m. on a Saturday. A gas push mower runs about 90–100 dB(A); the quietest robot mowers run in the mid-50s, a reduction so large that many owners genuinely forget the machine is out cutting. But not all robot mowers are equally quiet: the spread from the softest to the loudest is roughly 54 to 67 dB(A), and because every 10 dB roughly doubles perceived loudness, that gap is very audible. Below are the seven quietest robot lawn mowers of 2026, ranked by measured noise and matched to yard size and terrain, each with the manufacturer’s rated dB(A). Before you schedule any of them overnight, see our robot mower HOA and noise ordinance guide — quiet hours and covenant rules still apply no matter how low the dB(A) rating goes.

Updated October 31, 2026: navimow.com lists the 54 dB(A) Navimow H1500-VF as sold out, and its H2 successor is rated 60 dB(A), so the Gardena Sileno Minimo (57 dB(A)) is now the quietest mower here that you can easily buy new.

Earlier in October 2026: Added the Kress KR172, which our own Kress robot mower guide already cited as sitting “near the top of” this ranking at 59 dB — a claim this page hadn’t actually backed up until now. It slots in tied with the Navimow i2 AWD, and it’s the only mower at this noise level with no reference antenna to place on the property, thanks to Kress’s network RTK (RTKⁿ) system.

Segway Navimow H1 series — quietest rated, but sold out

Segway Navimow H1 series (H1500-VF)

Quietest rating we track · 54 dB(A) · wire-free RTK · sold out on navimow.com (Oct 31, 2026)

Rated at just 54 dB(A) during normal operation, per Segway — the lowest working noise of any robot mower we track, quieter than a normal conversation.
Wire-free RTK-GNSS navigation with virtual boundaries — no buried perimeter wire to install or repair.
Quiet enough to schedule early morning or overnight without disturbing the household or neighbors.
App control, anti-theft alarm and GPS tracking; systematic straight-line mowing pattern.
The H1500-VF is rated for 0.37 acre and was listed at $2,199 on navimow.com, where it shows as sold out as of October 31, 2026.

Availability update (October 31, 2026): navimow.com lists the H1500-VF as sold out. Its successor, the Navimow H2 (H210/H220), adds LiDAR and network RTK, but its North American manual lists a measured sound power level of 60 dB(A) (52 dB(A) sound pressure, ±3 dB(A), per EN 50636-2-107). Segway’s 54 dB(A) rating therefore applies to the older H1 hardware, not the H-series mower Navimow sells today.

If you can still find one new or refurbished and your single priority is silence, the Navimow H1 is the pick. At 54 dB(A) it’s the quietest-rated robot mower here — Segway itself compares it to the point where “weekends may never sound the same,” and in practice it’s soft enough that you can hold a conversation standing right next to it. It navigates wire-free by RTK-GNSS, so there’s no perimeter wire to trench, and it schedules itself around your day. The trade-off is that RTK needs a clear view of the sky, so heavily tree-shaded lawns may prefer a wired model below. For the full lineup and setup detail, see our Segway Navimow review and our wire-free robot mower guide.

Gardena Sileno Minimo — quietest for small yards

Gardena Sileno Minimo

Best for small tidy lawns · 57 dB(A) · boundary wire

Rated at just 57 dB(A), per Gardena — among the very quietest mowers made, and consistently near the top of independent low-noise tests.
Compact and light, designed for small lawns up to ~250–500 m² depending on version.
Boundary-wire navigation is reliable under tree cover where RTK models can struggle.
Bluetooth/app scheduling with a spiral cutting mode for patchy spots; handles narrow passages.
Built by the Gardena/Husqvarna group, so it shares proven quiet-drivetrain engineering.

For a small, tidy lawn where you want near-silence at a sensible price, the Gardena Sileno Minimo is the standout. Independent testers repeatedly rank it as one of the quietest robotic mowers available, and Gardena rates it at 57 dB(A) — barely above the Navimow and well under most of the field. It uses a boundary wire rather than RTK, which is actually an advantage under trees or beside buildings where satellite signal drops out. It’s built for compact yards rather than acreage, so pair it with a larger model if you have a big property, but for a courtyard, front garden or small back lawn it’s the quiet-lover’s value pick. See more small-lawn options in our best robot mower for small yards guide, or read our full Gardena Sileno robot mower review for the whole 2026 lineup.

Husqvarna Automower 415X — best premium quiet mower

Husqvarna Automower 415X

Best premium quiet + GPS · ~58–59 dB(A) · boundary wire

Residential Automower models run around 58–59 dB(A), per Husqvarna — Husqvarna markets the "ultra-quiet" smart mowing technology across the X range.
GPS-assisted navigation maps your lawn for efficient, even coverage on up to ~0.4 acre.
Automower Connect app with anti-theft GPS tracking, geofence alarm and remote scheduling.
Weatherproof and reliable, with Husqvarna's long track record in robotic mowing.
Boundary-wire guidance works dependably in shaded or signal-difficult yards.

Husqvarna essentially defined the quiet robot mower, and its residential Automower line stays in the low-noise conversation at about 58–59 dB(A). The 415X pairs that hush with GPS-assisted navigation, a mature app with real anti-theft features, and the brand’s renowned reliability. It uses a boundary wire — a plus for tree-shaded lawns — and cuts a clean, even lawn on plots up to roughly 0.4 acre. It’s a premium buy, but for owners who want a proven, quiet, well-supported machine rather than the newest wire-free tech, it’s the safe choice. Our full Husqvarna Automower 415X review covers its coverage and slope limits in detail, and for the wider Automower range, see our best Husqvarna Automower guide.

Kress KR172 — quietest wire-free mower with no antenna to place

Kress KR172

Best quiet mower with no antenna to place · 59 dB · wire-free network RTK

Rated at 59 dB, per Kress — tied with the Navimow i2 AWD for the second-quietest wire-free mower we track, and genuinely one of the quieter satellite mowers on the market.
Uses Kress's network RTK (RTKⁿ) system instead of a property-mounted reference antenna — no hardware to stake out or mount on the house at all, unlike the Navimow and Mammotion entries above and below it.
Covers up to 0.5 acre recommended / 0.7 acre max, with a 40% slope rating.
20V 6 Ah battery, IPX5 hose-washable chassis, 28.46 lbs, per Kress.
Priced from $1,699.99 (regularly $2,499.99), the least expensive mower in this quiet tier.

The Kress KR172 earns its spot here on a genuine technicality worth knowing: at 59 dB it’s tied with the Navimow i2 AWD for the quietest wire-free mower outside the Navimow H series and Gardena Sileno, but it gets there with no reference-station hardware to place on your property at all — Kress’s network RTK (RTKⁿ) pulls its correction signal over cellular/network connectivity instead of a stake-mounted antenna. That makes it the pick if you want Navimow-tier quiet without finding a clear-sky spot for an antenna. See our full Kress robot mower guide for the KR172 vs KR173 vs KR174 breakdown.

Segway Navimow i2 AWD — quietest for slopes

Segway Navimow i2 AWD

Best quiet mower for hills · 59 dB(A) · wire-free AWD

Operates at 59 dB(A) during normal work — about the level of a microwave — per Segway, staying quiet even while climbing.
All-wheel drive tackles slopes and uneven ground that stall single-drive mowers.
Wire-free RTK navigation with vision assist for virtual boundaries and obstacle avoidance.
Covers up to roughly 0.5 acre; app scheduling with multi-zone support.
A rare combination of low noise and genuine slope capability in one machine.

Quiet and hilly usually don’t go together — until the Navimow i2 AWD. Segway rates it at 59 dB(A), roughly a microwave’s hum, while its all-wheel drive handles banks and slopes that defeat flat-lawn mowers. It navigates wire-free with RTK plus vision, so you get virtual boundaries and obstacle avoidance without trenching. For a sloped suburban lot where you still want early-morning-quiet operation, it’s the best of both worlds — see our full Navimow i2 AWD review for the i206 vs i210 breakdown and pricing. If terrain is your bigger concern, cross-reference our robot lawn mower for hills guide.

Mammotion Luba AWD — quietest large / wire-free mower

Mammotion Luba AWD

Best quiet mower for big lawns · under 60 dB(A) · wire-free AWD

Rated at low noise under 60 dB(A), per Mammotion — impressively quiet for a machine that covers up to 2.5 acres.
All-wheel drive with steep slope capability (up to ~65–80% depending on model) for rough, large properties.
Wire-free RTK fused with a vision system for boundaries and obstacle handling — no perimeter wire.
App and voice control, multi-zone management, and dual-blade cutting for even large lawns.
Self-installed, so no dealer reference-station fees on big acreage.

Large lawns don’t have to be loud. The Mammotion Luba AWD covers up to 2.5 acres yet stays under 60 dB(A), per Mammotion — remarkable for a machine with the drive and battery to cut serious acreage. Its all-wheel drive and steep-slope rating make it the quiet choice for big, uneven or rural properties, and its wire-free RTK-plus-vision setup means no buried wire across all that ground. If you have a large lawn and want it cut quietly and unattended, the Luba AWD is the pick. See our full Mammotion Luba 2 AWD review and best robot mower for large yards guide.

Worx Landroid — budget option (louder)

Worx Landroid

Best budget · ~67 dB(A) · boundary wire

Rated around 67 dB(A) in its owner's manual — one of the louder robot mowers, though still far quieter than any gas mower.
Lowest entry price here, with boundary-wire navigation and AIA cut-to-edge technology.
Modular add-ons for anti-collision, GPS tracking and off-limits zones.
Reliable under tree cover where RTK models struggle; covers up to ~0.5 acre.
The pick if budget matters more than absolute silence.

Included here for honesty and value: the Worx Landroid is the affordable robot mower most shoppers first consider, but it’s also the loudest in this group at roughly 67 dB(A) per its owner’s manual — about 10–13 dB above the Navimow and Gardena, which is clearly audible. It’s still dramatically quieter than a gas mower and perfectly fine for daytime mowing, and its boundary-wire system is dependable under trees. If your budget is tight and silence isn’t the deciding factor, it’s a solid buy; if quiet is the whole point, spend up to a Navimow or Gardena Sileno.

Robot mower noise by the numbers

54 dB(A) — the quietest we track: The Segway Navimow H1500-VF is rated at no more than 54 dB(A), per Segway, the lowest working noise of any robot mower here. It is sold out on navimow.com as of October 31, 2026.
60 dB(A) for the H2: The current Navimow H2 is rated 60 dB(A) sound power and 52 dB(A) sound pressure in its manual. Sound power is the total noise the machine emits; sound pressure is what you hear near it, so check which figure a spec sheet quotes before comparing.
57 dB(A) Gardena Sileno: Gardena rates the Sileno Minimo at 57 dB(A), and independent tests repeatedly place it among the very quietest robotic mowers made.
59 dB with zero on-property antenna: The Kress KR172 matches the Navimow i2 AWD’s 59 dB rating, per Kress, but reaches it with network RTK (RTKⁿ) instead of a reference antenna you have to stake out — the only mower in this tier with no positioning hardware to place on your lawn.
~13 dB spread across the field: From the 54 dB(A) Navimow to the ~67 dB(A) Worx Landroid is roughly a 13 dB gap — and because every 10 dB roughly doubles perceived loudness, the loudest model here sounds well over twice as loud as the quietest.
30–40 dB quieter than gas: A gas push mower runs about 90–100 dB(A); the quiet robot mowers here run 54–60 dB(A), a 30–40 dB reduction that’s the difference between needing ear protection and forgetting the mower is running.
60 → 74 dB(A) on one machine: PCWorld’s 2026 lab measurements of the tracked Lymow One Plus show why mowing mode matters as much as model — 60 dB(A) in eco and 62 dB(A) in standard, but 74 dB(A) in turbo, a jump PCWorld said made it “virtually impossible to relax in the yard.” Rated dB(A) figures are usually the quietest mode; check what the loud mode does before scheduling around neighbors.
58 → 68 dB(A), same pattern: The new Anthbot N8 is quiet enough at 58 dB(A) while mowing or mulching, per Anthbot, but jumps to 68 dB(A) — roughly twice as loud — whenever it’s actively vacuuming clippings or leaves into its collection bag. It’s not on this list because that collection-mode noise is the one most owners will actually hear during a cleanup run, not the quieter headline spec.

How to choose a quiet robot mower

Start with how quiet you actually need it: if you want to mow overnight or share a fence line with light-sleeping neighbors, target the 54–57 dB(A) tier (Gardena Sileno, or a Navimow H1 if you can still find one). Also check measured noise per mode, not just the spec sheet: independent tests show the spread within one mower can exceed the spread between mowers — PCWorld measured the heavy-duty Lymow One Plus at 60 dB(A) in eco but 74 dB(A) in turbo, a difference of well over double the perceived loudness. For most owners, anything in the 58–60 dB(A) band (Husqvarna Automower, Kress KR172, Navimow i2, Mammotion Luba) is already refrigerator-quiet. Then match yard size — Gardena Sileno and small Navimow/Automower models for compact lawns, Mammotion Luba for acreage — and terrain, where the AWD Navimow i2 and Luba handle slopes without getting louder. Finally weigh navigation: RTK wire-free models are tidiest but need sky view, while boundary-wire Gardena and Husqvarna machines stay quiet and reliable under trees. A quiet mower matters most in homes with pets — see our best robot lawn mower for dogs guide for the safest, least-startling picks. For the complete lineup, start with our best robot lawn mower pillar.

The bottom line

For the quietest mow you can buy new today, the Gardena Sileno Minimo (57 dB(A)) is the pick for small lawns. The Segway Navimow H1 holds the lowest rating at 54 dB(A), but it is sold out on navimow.com, and the Navimow H2 that replaces it is rated 60 dB(A). Want quiet plus hills or acreage? The Segway Navimow i2 AWD and Mammotion Luba AWD stay under 60 dB(A) while climbing slopes. Whichever you choose, you’ll trade a gas mower’s 90–100 dB(A) roar for a machine you can barely hear — and get your weekends back in silence.
