The best robot lawn mowers for complex gardens

Most UK gardens aren't one open rectangle. A front and back lawn joined by a side return, a lawn broken up by beds and trees, a garden on two levels, or a plot overshadowed by the house: each of these narrows the list of robot mowers that will work well. This shortlist is for those gardens. We haven't tested these mowers hands-on; the picks are desk-based judgements from manufacturer specifications, manuals, UK warranty terms and prices. For the background, read our guide to complex gardens.

How we chose

We started with every current, UK-available family and scored the fit for complicated layouts on four points:

• Minimum passage width. The narrowest gap the manufacturer says the mower can drive through. Many don't publish one; we favoured those that do, and those with figures under 1 m.
• Zones and linking. How many separate areas the app can manage and whether it can link them with a drawn path.
• Navigation where the sky is blocked. Side passages and tree-shaded lawns are where RTK-only mowers struggle. We preferred LiDAR, camera and hybrid navigation, and wired mowers where shade is heavy.
• Weight and practicality. If two lawns aren't linked, someone has to carry the mower. Lighter is better.

We also preferred families with a published UK RRP or brand-store price, and noted where stock was short.

What to measure first

Measure your narrowest link with everything normally in it: wheelie bins, a downpipe, the hinge side of an open gate, plants that flop over in June. A published passage width is a best case on a flat, clear route. If your gap is within about 10 cm of it, expect the mower to hesitate or need help, especially where the passage also has a step, a kerb or a slope.

Mammotion LUBA mini 2 AWD (1500)

The Mammotion LUBA mini 2 AWD 1500 is our first choice because its navigation suits exactly the places complex gardens are hardest. It uses a 360° LiDAR scanner and two cameras with no RTK, so a passage between the house and a fence, or a lawn under trees, doesn't cost it a satellite fix. Mammotion quotes a minimum passage width of 68 cm and up to 20 zones, and all-wheel drive with an 80% rating handles ramps and banks between levels.

The trade-offs are weight, at 17.2 kg, and a quoted 65 dB(A). LiDAR also has less to see on a wide, open lawn. The 1500 costs £1,499.

Mammotion YUKA mini 2 (1000)

If your side passage is genuinely narrow, the Mammotion YUKA mini 2 has the smallest published minimum passage width of any current wire-free mower in our catalogue: 55 cm. The 1000 adds LiDAR to its cameras, manages 10 zones, and at 10.9 kg it's light enough to lift between lawns that aren't linked. The 800 uses cameras with network RTK instead, which is less suited to shaded passages.

It's two-wheel drive with a 45% limit, and 4G is an optional module on the 1000. Both versions were out of stock on Mammotion's UK store at the end of September 2026, so check availability. The 1000 costs £999.

Segway Navimow i2 LiDAR

The Segway Navimow i2 LiDAR is the value choice for gardens hemmed in by houses, walls and trees. It navigates by LiDAR and a camera, with no satellite or 4G dependence for positioning, handles up to 20 zones and is rated for 800–2,000 m². Built-in 4G gives remote control and tracking, and the warranty is 3 years.

Navimow doesn't publish a minimum passage width, so compare the mower's dimensions with your narrowest gap before buying. Two-wheel drive limits it to 45%. Prices start from £999.

Segway Navimow H2

The Segway Navimow H2 Series combines solid-state LiDAR, network RTK and a camera, so it has a fallback in both shaded passages and open lawn. Navimow quotes a minimum passage width of 70 cm, up to 30 zones and full edge cutting, with sizes from 600–3,000 m². Because it's sold through authorised dealers who offer installation, it suits buyers who'd rather have an expert map a fiddly garden.

That route also means no online discounts, and Navimow includes 12 months of 4G data. It's two-wheel drive with a 45% limit. Prices start from £1,499.

Honda Miimo HRM (1500 Live)

Where much of the lawn is under mature trees, a boundary wire is still the most predictable option, and the Honda Miimo HRM 1000 to 4000 is our wired pick. Honda gives 60 cm wire to wire for models with a shortcut wire (the HRM 1000 doesn't have one). The Live versions add built-in 4G, GPS tracking and a geofence, and Honda's 5 years warranty is the longest we list.

The cost is installation: every bed, tree and pond needs its own wire island, and changing the layout means moving wire. Obstacle detection is contact-only, and the warranty needs dealer registration and servicing. The 1500 Live costs £1,449.

Buying advice for complex gardens

• Sketch the garden. Measure each lawn separately with our lawn size tool, and mark which areas can be linked by driving and which need carrying.
• Add more headroom. A divided lawn takes longer to cut. Allow 40–50% above your total lawn area when choosing a rated area.
• Mark the shade. Note which areas are under trees or within a few metres of a tall building. If several are, lean towards LiDAR, hybrid or wired navigation; our navigation guide explains why.
• Check the route surface. Wire-free mowers can usually cross short paved or firm paths if you draw a channel, but not steps. Gates must be open on mowing days.
• Check multi-map support. If a lawn isn't linked at all, make sure the app stores separate maps and find out whether the second area needs its own charging station.
• Compare with two mowers. For two decent-sized lawns with no link, two smaller mowers can be simpler and not much dearer than one large one.
