The best robot mowers for sloping lawns in Australia
Quick answer: For a steep block, buy an all-wheel-drive robot rated well above your steepest patch. The Mammotion Luba mini 2 AWD 1500 ($3,399) is rated for 80% (38.6°) and navigates by LiDAR, and the Luba Mini AWD 800 has the same 80% rating for $2,399 at Robot Mowers Australia ($2,499 at Bunnings). For moderate slopes up to 45% (24°), the Segway Navimow i206 AWD ($2,398 at Bunnings) is the simpler, wire-free choice.

How we picked: We compared these 7 picks on max slope, drive, lawn area and price, using maker specs, Australian retailer prices and owner reports. We haven't tested them hands-on yet, and maker claims are labelled as theirs. Commission never changes the order. Full method.
Slopes are where robot mowers come unstuck, literally. A robot that is happy on a flat backyard can spin its wheels, slide sideways or refuse to climb back to its dock on a steep front lawn. The good news is that the range of robots rated for real hills is now wide, and several are sold at Bunnings. The catch is that makers quote slope in a unit most of us never use. Prices are from Bunnings, Mammotion, Segway Navimow, Ecovacs, Husqvarna and Robot Mowers Australia on 18 October 2026 (the Luba Mini AWD 800 on 21 October); for models also on Amazon Australia, check the current price on Amazon. We compared maker ratings and retailer listings; we have not tested these robots on our own slopes.
Percent is not degrees
Robot mower makers rate slopes in percent, which is the rise divided by the run: a 45% slope rises 45 cm for every 1 m across. That is about 24 degrees, not 45. A true 45 degree bank would be 100%. Mix the two up and you will buy a robot that cannot climb half the slope you thought it could.
| Slope in percent | In degrees | Robots rated to it |
|---|---|---|
| 15% | 8.5° | Husqvarna 405X along its boundary wire |
| 25% | 14.0° | Gardena Sileno Minimo 250 |
| 30% | 16.7° | Navimow i105A and i108A, Worx Vision Cloud |
| 40% | 21.8° | Husqvarna 405X inside the lawn |
| 45% | 24.2° | Navimow i206 and i210 AWD, Ecovacs Goat O600, Roborock Q105, Mammotion Yuka minis |
| 50% | 26.6° | Navimow X315A |
| 80% | 38.7° (Mammotion quotes 38.6°) | Mammotion Luba Mini AWD 800, Luba mini 2 AWD, Luba 3 AWD |
| 84% | 40.0° | Navimow X450 AWD |
Even retailers slip. Bunnings’ feature list for the Mammotion Yuka Mini 600 says “slopes under 45% (28 degrees)”; 45% is about 24 degrees, and Mammotion’s own figure for its 45% robots is 24°.
How to measure your slope
You need a straight board or a long spirit level about 1 m long. Put one end on the slope at its steepest point, pointing straight downhill, and lift the low end until the level reads flat. Measure the gap under the low end in centimetres. Over a 1 m board, that measurement is close to the slope in percent: a 30 cm gap is a 30% slope, about 17 degrees. A phone level app laid on the board gives degrees, which you can convert with the table. Measure the steepest few metres, not the average, and check the path the robot takes back to its dock.
What makes a robot good on hills
Drive. Most robots drive two wheels. All-wheel drive spreads the work across more wheels: Navimow says the i206 AWD has three independent motors and electronic stability control, Mammotion says the Luba 3 has four independent motors, and Robot Mowers Australia says the Navimow X450 has independent suspension and traction control.
Headroom. A slope rating is a maximum in good conditions. Wet grass, a soft spot or a bump halfway up all eat into it. Buy a robot rated at least 10 to 15 percentage points above your steepest patch.
The boundary. Husqvarna rates the 405X for 40% inside the lawn but only 15% along the boundary wire, where the robot turns at the edge. If your steep part is also the edge of the lawn, that lower figure is the one that matters. eufy’s advice for the C15 applies to any robot: mark areas steeper than the rating as no-go zones in the app.
The picks
The Mammotion Luba mini 2 AWD 1500 is the one to buy for a genuinely steep lawn. It is rated for 80% (38.6°), navigates by 360° LiDAR and two cameras so it does not depend on satellite signal along a fence line, and has a separate edge disc. Robot Mowers Australia sells it for $3,399 and Mammotion for $3,499, with built-in 4G, three years of data and a three-year warranty.
The Mammotion Luba Mini AWD 800 has the same 80% rating and AWD for $2,399 at Robot Mowers Australia, or $2,499 at Bunnings. It is the older generation, positioning by NetRTK and stereo cameras rather than LiDAR, and is rated for 800 m², but no other robot we found gives you an 80% rating for less.
For moderate slopes up to 45% (24°), the Segway Navimow i206 AWD is $2,398 at Bunnings, with no wire, no antenna and 4G built in. For big steep blocks, the Mammotion Luba 3 AWD 1500 ($3,899) adds a 400 mm cut from two discs and steps over kerbs and roots up to 50 mm. If you need more than any of these, the Navimow X450 AWD is rated for 84% (40°) and 5,000 m², at $5,999 from Robot Mowers Australia.
On a smaller budget, the Ecovacs Goat O600 RTK ($1,299) is rated for 45% (24°) and crosses 3 cm barriers, and the boundary-wire Husqvarna Automower 405X handles 40% for a campaign price of $1,434 with an installation kit. For the full field, see the main robot mower guide and the Mammotion vs Segway Navimow comparison.
Safety on slopes
A robot on a slope near a pool, a retaining wall or a drop needs more care than one on a flat lawn. Set no-go zones around drops in the app and keep the robot off slopes steeper than its rating. Mammotion says the Yuka mini 2 detects cliffs, steps and pool edges, which is a useful backup, not a substitute for a no-go zone. Keep children and pets inside while any robot mows.
The one trap
Buying a robot rated at exactly your slope. A 45% robot on a 45% bank has nothing in reserve when the grass is wet, and if it cannot climb back to the dock, it sits on the lawn with a flat battery. Measure your steepest patch, convert it, and buy at least one class up: a 30% lawn suits a 45% robot, and a 45% lawn suits an 80% AWD model. If no robot fits your budget for the slope you have, a light battery lawn mower such as the 8.1 kg Bosch EasyMower is easier to carry up a bank than any robot.

Frequently asked questions
What is the best robot mower for slopes in Australia?
For steep lawns, the Mammotion Luba mini 2 AWD 1500, rated for 80% (38.6°). For slopes up to 45% (24°), the Segway Navimow i206 AWD is cheaper and simpler. Always buy a rating comfortably above your steepest patch.
Is a 45% slope the same as 45 degrees?
No. Slope percent is rise over run: 45% means 45 cm of rise across 1 m, which is about 24 degrees. A 45 degree slope would be 100%. Robot mower makers usually quote percent.
How steep a slope can a robot mower handle?
Two-wheel-drive robots in this guide are rated from 25% (Gardena Minimo 250) to 45%. All-wheel-drive Mammotion Luba models are rated to 80% (38.6°), and the Segway Navimow X450 AWD to 84% (40°).
How do I measure the slope of my lawn?
Lay a straight 1 m board on the slope pointing downhill, lift the low end until a spirit level on the board reads level, and measure the gap under it in centimetres. That number is roughly the slope in percent. A phone level app gives degrees directly.
Do robot mowers work on wet slopes?
Traction drops on wet grass, which is one reason to leave headroom. Mammotion pitches its AWD for wet or uneven terrain, and several robots, including the Ozito Freelexo Cam, Dreame A1 Pro and Mammotion Yuka Mini, have rain sensors that send them back to the dock.
