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 | Ecovacs GOAT A1600 RTK |
|---|---|---|
| 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. | GoodRated up to 1,600 square meters, roughly 0.4 acre, so a sub-quarter-acre lot sits well inside its range. |
| ¼ – ½ acre | 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. | DependsRated up to about 0.4 acre, with 1,280 square meters (0.32 acre) suggested; lots toward half an acre exceed it. |
| 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. | PoorStated maximum is 1,600 square meters, about 0.4 acre; lawns above half an acre are outside the 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 the stated 50 percent slope rating and the six-step cutting height range. |
| Gentle slopesthey differ | PoorNo slope rating is published, and the same test documents satellite reception failing near ordinary garden features on flat ground already. | GoodThe maker's 50 percent slope rating covers moderate grades; no independent slope test was reviewed. |
| Steep / hillythey differ | PoorNo slope rating is published at all, and independent testing already reports the satellite signal failing on flat, open ground. | DependsMaker states slopes up to 50 percent; no independent steep-lawn test was reviewed, so traction on wet steep grass is unverified. |
| Grass type | ||
| Typical lawn grassthey differ | DependsTwo rear cutting discs handle typical turf grass, but no cutting height or blade specification is published for this model. | GoodCutting height adjusts from 30 to 90 mm in six steps, which covers standard turf heights. |
| Mixed / tall growth | DependsNo cutting height range, blade-power figures, or mulching capability are published; nothing documents this model on mixed or overgrown grass. | DependsCutting height tops out at 90 mm, about 3.5 inches, so taller growth is beyond its stated range. |
| 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 independent test on dense or thick turf was found; the 33 cm dual-blade deck is the only stated cutting hardware. |
| 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. | GoodWire-free: positioning comes from LiDAR-assisted RTK and vision, so no perimeter wire is installed. |
| Wire required | PoorThere is no wired boundary option; positioning is satellite-only, with no perimeter wire supported as a fallback. | PoorNo boundary cable is used; the lawn is bounded by satellite and vision positioning, so a wire-based setup does not apply. |
| No preference | GoodNo preference fits either way, though a hands-on test of this exact unit reports daily retrieval after failed satellite runs. | GoodWorks without any perimeter wire, which suits an owner with no boundary preference. |
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.

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.
Ecovacs GOAT A1600 RTK
Going wire-free removes the boundary cable chore, and the stated 1,600 square meter ceiling, about 0.4 acre, becomes the limit on lawn size.
Obstacle recognition is documented as a feature; how it treats hoses, toys and animals is not established by the sources reviewed.
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.
Ecovacs GOAT A1600 RTK
- Lawns above about half an acre
- Stated coverage tops out at 1,600 square meters, about 0.4 acre, and the maker-suggested area is smaller at 1,280 square meters, so larger properties sit outside the rating.
- Owners who need an independently proven steep-slope record
- The 50 percent slope rating comes from the maker. No independent steep-lawn or wet-grass traction test was reviewed, so performance at the top of that rating is unverified.
- Tall, unmown grass or meadow-length turf
- Cutting height tops out at 90 mm, about 3.5 inches, and the deck is 33 cm wide, so overgrown or very dense growth sits outside the stated range.
- Households that need confirmed US pricing and availability
- A European list price of EUR 1,599 is verified. A US list price was not, so US cost, retailers and support terms remain unknown for this record.
- Yards where tree canopy or buildings cover most of the sky
- Satellite positioning needs a view of the sky. The maker pairs it with LiDAR and vision, but performance under heavy cover was not independently reviewed.
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.
Ecovacs GOAT A1600 RTK
- Monthly: Wipe grass clippings from the deck, wheels and blade area during the growing season.
- Seasonally: Inspect the dual blades and replace them as they dull; blade price was not verified.
- Seasonally: Keep branches and new structures from blocking the satellite view around the lawn and charging station.
- As needed: Clear obstacles the app flags and update no-go zones after changing the garden layout.
- As needed: Install firmware and app updates when the maker releases them.
- Annually: Follow the manual’s off-season storage steps; specifics were not verified for this record.
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.

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.
