All robot lawn mowers. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | smart Sileno free 600 | MOVA LiDAX Ultra Gen 2 |
|---|---|---|
| Yard size | ||
| Under ¼ acrethey differ | DependsRated to 6,458 sq ft on paper, but a hands-on test of this exact model reports daily retrieval after failed satellite runs. | GoodReports rate it for lawns up to 1,000 m², about a quarter acre. |
| ¼ – ½ acrethey differ | Depends6,458 sq ft (0.15 acres) sits well below this bracket's quarter-acre floor, before Galaxus's daily-retrieval finding is even a factor. | PoorThe reported 1,000 m² rating stops at about a quarter acre. |
| Over ½ acre | Poor6,458 sq ft is the documented coverage ceiling; a half-acre-plus lawn exceeds it before the satellite-reception problems even become relevant. | PoorLots over half an acre are more than double the reported 1,000 m² rating. |
| Terrain | ||
| Mostly flatthey differ | DependsA hands-on test found GPS reception unreliable near the edges of the house even on level ground, unrelated to slope. | GoodFlat lawns sit well inside MOVA's 45% slope rating. |
| Gentle slopesthey differ | PoorNo slope rating is published, and the same test documents satellite reception failing near ordinary garden features on flat ground already. | DependsMOVA rates it for 45% slopes, and no independent slope test exists. |
| Steep / hilly | PoorNo slope rating is published at all, and independent testing already reports the satellite signal failing on flat, open ground. | PoorSteep slopes exceed MOVA's listed 45% maximum. |
| Grass type | ||
| Typical lawn grass | DependsTwo rear cutting discs handle typical turf grass, but no cutting height or blade specification is published for this model. | DependsNo independent cutting test of Gen 2 exists before its November 2026 release. |
| Mixed / tall growth | DependsNo cutting height range, blade-power figures, or mulching capability are published; nothing documents this model on mixed or overgrown grass. | DependsMOVA has not published a cutting height range for Gen 2. |
| Thick (Bermuda / Zoysia) | DependsNo cutting height, blade-power, or mulching specification is published for dense Bermuda or Zoysia; the rear-disc design is not detailed further. | DependsNo test of dense turf exists, and cutting-system figures are unpublished. |
| Boundary setup | ||
| Wireless requiredthey differ | DependsSatellite positioning replaces the wire, but a hands-on test of this exact model reports daily retrieval from the lawn. | GoodLiDAR and an HDR AI camera map the lawn with no wire or RTK station, per MOVA. |
| Wire required | PoorThere is no wired boundary option; positioning is satellite-only, with no perimeter wire supported as a fallback. | PoorThere is no boundary-wire mode; Gen 2 relies on UltraView 2.0 navigation. |
| No preference | GoodNo preference fits either way, though a hands-on test of this exact unit reports daily retrieval after failed satellite runs. | GoodWire-free navigation meets this preference with no perimeter installation. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Gardena smart Sileno free 600
Wire-free satellite positioning removes the trench-digging step, but independent testing of this exact model documents the owner retrieving it from the lawn every morning.
Rear twin-disc cutting trims the lawn edge the wire-guided SILENO models cannot reach, yet GPS reception is reported unreliable under small trees and near the house.
A published European price sits inside Gardena’s existing support range, though no US channel exists, so American buyers have no domestic warranty or parts path.
MOVA LiDAX Ultra Gen 2
A separate edge module aims to end hand trimming, and its 0 cm claim comes from MOVA with no independent test yet.
A heat sensor guards the exposed edge blades, but how reliably it stops them has not been independently checked.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Gardena smart Sileno free 600
- Yards with small trees or house-adjacent edges
- A hands-on test of this exact model documents GPS reception failing specifically under small trees and along the edges of the house, both common garden features.
- Buyers located in the United States
- Gardena lists the SILENO free range on its international and European sites only, with a euro list price and no domestic warranty or parts channel.
- Owners who need daily unattended operation
- A hands-on review reports the owner carrying the machine back to its base every morning, meaning it is not finishing its job unattended the way the rating implies.
- Buyers wanting a proven boundary-accuracy record
- No independent test of boundary accuracy or cut quality exists beyond that hands-on review, which specifically attributes the machine's failures to unreliable satellite reception under tree cover.
MOVA LiDAX Ultra Gen 2
- Lawns larger than about 1,000 m²
- Two separate reports say the LiDAX Ultra Gen 2 is designed for lawns up to 1,000 m².
- Buyers who need a mower before November
- Release is reported for November 2026, and MOVA has not announced a price.
- Steep yards
- MOVA lists a 45% slope rating on its IFA 2026 page.
- Buyers who want independent test results first
- The 0 cm edge cut and heat-sensor blade stop are MOVA claims with no independent test yet.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Gardena smart Sileno free 600
- Weekly: Examine both blade discs and their pivoting blades, then clean the discs and chassis with a brush and running water; the manual forbids pressure washers and solvents.
- Weekly: Brush grass out of the wheels; the manual warns clogged wheels spoil performance on slopes.
- Monthly: Replace the blades and screws on both cutting discs as complete sets; Gardena documents a usual blade life of 4 to 7 weeks. A 9-blade kit with screws is $26.99 on Gardena’s US shop, and the free’s two discs take 6 blades per change.
- As needed: Clean the charging plates and contact plates with a fine emery cloth and clear grass and twigs out of the charging station; the manual sets no interval for either.
- As needed: Install firmware updates when the GARDENA smart system App offers them.
- Seasonally: For winter, fully charge, switch off, clean, and store the mower dry and frost free on level ground; a charging station left outdoors should keep its power supply connected.
MOVA LiDAX Ultra Gen 2
- As needed: Clear clippings from the main cutting disc and the right-side edge module.
- As needed: Replace the main blades and flexible polymer edge blades; MOVA has not published intervals.
- As needed: Wipe the LiDAR dome and 1080p camera.
- Seasonally: Clean and store the mower for winter.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
| Gardena smart Sileno free 600 | Provisional | 3 | Sep 2026 |
| MOVA LiDAX Ultra Gen 2 | Pre-Release | 6 | Sep 2026 |
Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
