Best Robot Lawn Mower for Large Gardens UK
Last updated: 2026-07-06 · Prices checked against UK retailers on this date
Above ~600m², mower choice is about battery, cutting rate and mapping — a machine rated below your lawn size will spend all day, every day, mowing. Here's what's currently available through AutoLawn UK's affiliate partners: Navimow's LiDAR i2 series (800–2,000m²) and Husqvarna's dealer-backed wired flagships (up to 3,500m²).

Best value for large lawns: Navimow i215 LiDAR
The standout of Navimow's 2026 range: 1,500m² coverage with LiDAR for £1,099 — the same price as the 800m² i208 LiDAR. If your lawn is 800–1,200m², this is where the coverage-per-pound curve peaks.
Segway Navimow i215 LiDAR
£1,099 (RRP £1,199)Best for: Large lawns (800–1,200m²) — 1,500m² coverage and LiDAR for the price of the 800m² model.
Avoid if: You need AWD for slopes — the i208 AWD is the wire-free option we can recommend, though it doesn't publish a slope %.
Pros
- Best coverage-per-pound in the Navimow range
- LiDAR handles tree-lined large gardens
Cons
- 2WD — not a slope machine
- Larger i220 exists if you're at the top of the range

The top of the wire-free range: Navimow i220 LiDAR
Segway Navimow i220 LiDAR
£1,399Best for: The top of Navimow's mainstream range — large gardens up to 2,000m² with tree cover, without stepping up to a wired estate machine.
Avoid if: Your lawn is under 1,200m² (the i215 LiDAR is £300 cheaper for the same tech) or over 2,000m² (you're into Husqvarna's wired territory).
Pros
- Largest coverage in the current Navimow lineup
- LiDAR handles tree-lined large plots
- Still a fraction of a wired estate machine's price
Cons
- No published slope rating
- 2,000m² is a hard ceiling — nothing wire-free and monetisable goes bigger right now

Above 2,000m²: an honest gap
We won't pretend otherwise — once your lawn passes 2,000m², the wire-free options AutoLawn UK can currently recommend run out, and the only route to real paddock-scale coverage is a wired Husqvarna. The Automower 535 AWD (£4,899, up to 3,500m²) is the one to look at: a manufacturer-backed AWD platform with the UK's strongest dealer network, for gardens where downtime isn't an option.
Husqvarna Automower 535 AWD
£4,899Best for: Large, steep estates where downtime is unacceptable and dealer servicing matters more than price.
Avoid if: Budget is under £2,500 — the wire-free AWD options cost a third as much.
Pros
- Proven AWD on extreme slopes
- Dealer-installed and dealer-serviced
Cons
- £4,899 plus wired installation
- Wire-free rivals now match much of the capability for far less

What to check before buying for a large garden
- Zones and routes: can the mower physically travel between your lawns? Gates, steps and gravel paths decide this — check passage-width specs against your narrowest gap.
- Per-charge coverage vs total rating: a large rating means multiple sessions; check the per-day figure where the manufacturer publishes one.
- Sky view across the whole plot: large gardens usually have trees — that's exactly where LiDAR earns its premium over pure RTK.
- Terrain honesty: big rural lawns are rarely bowling greens. Reviewers flag camera-only flat-lawn machines (like the Eufy E15) struggling on damp, uneven ground — this category wants AWD or at least robust 2WD.
Common mistakes
- Running at 100% of rating — a 1,000m² lawn needs a 1,300m²+ rating for weather slack.
- Buying two small mowers instead of one right one — multi-zone mapping made this obsolete.
- Paying flagship money for flat, open ground — the i215 at £1,099 covers a huge share of "large garden" cases; save the Husqvarna premium for genuinely oversized or steep plots.

FAQs
How big a lawn can a robot mower handle in the UK?
Among the wire-free brands AutoLawn UK currently has affiliate relationships with, the Navimow i220 LiDAR tops out at 2,000m². Beyond that, wired Husqvarna Automowers reach up to 3,500m² (535 AWD). Most 'large' UK gardens (600–1,500m²) are comfortably covered by mid-range models like the Navimow i215 LiDAR.
Do I need multiple robot mowers for a big garden?
Usually not — modern multi-zone mapping lets one mower handle front and back lawns or separate paddocks, provided it can travel between them or you carry it. One correctly-rated mower beats two small ones.
Is Husqvarna worth the premium for large gardens?
Husqvarna's dealer network, servicing and parts availability are the strongest in the UK — that's what the premium buys, along with coverage beyond what current wire-free options reach. If your lawn is under 2,000m², the Navimow range is far cheaper.
