Last tested: March 2026. William re-tested the Mammotion LUBA 2 and Segway Navimow i2 across three gardens in Surrey and Berkshire. All prices and availability verified.
Robot lawn mowers have gone from novelty gadget to genuinely practical garden tool. The latest models navigate without boundary wires, handle steep slopes, and produce a cut quality that rivals a cylinder mower — all while you do absolutely nothing.
We've tested seven of the best robot mowers available in the UK right now, from budget-friendly wire models under £400 to premium RTK-guided machines that handle half an acre. Below you'll find our honest verdicts, a side-by-side comparison, and a detailed buying guide so you pick the right one for your garden.
I was sceptical about robot mowers until I installed a Worx Landroid for a friend in 2023. Three months later, his lawn looked better than it ever had with manual mowing. I've since tested seven models across gardens from 100m² to 2,000m².
| Model | Best For | Navigation | Max Area | Max Slope | Price |
|---|---|---|---|---|---|
| Mammotion LUBA 2 AWD 5000 | Overall | RTK + Vision (wire-free) | 5,000m² | 38° | ~£1,600 |
| Segway Navimow i2 AWD | Value Wire-Free | RTK (wire-free) | 1,500m² | 35° | ~£900 |
| Husqvarna 430X NERA | Complex Gardens | EPOS (wire-free) | 3,200m² | 45% | ~£3,000 |
| Flymo EasiLife 200 | Budget | Boundary wire | 200m² | 25% | ~£400 |
| Worx Landroid M WR141E | Mid-Range | Boundary wire | 500m² | 35% | ~£600 |
| Mammotion YUKA 2000 | Stripes | RTK + Vision (wire-free) | 2,000m² | 30° | ~£1,200 |
| Gardena SILENO City 600 | Small Gardens | Boundary wire | 600m² | 25% | ~£700 |

The LUBA 2 AWD 5000 is the robot mower we'd recommend to most people with a medium to large garden. It uses RTK satellite positioning combined with onboard vision cameras to map your lawn with centimetre-level accuracy — no boundary wire needed. You set virtual zones through the app, and the mower follows systematic mowing lines rather than the random-bounce pattern older robots rely on.
All-wheel drive gives it serious traction on slopes and damp grass. The cutting width of 400mm is generous, and the three-blade disc system produces a clean, even finish. Setup takes roughly 30 minutes — walk the perimeter with the mower in mapping mode, mark obstacles as no-go zones in the app, and you're done.
The app is well-designed — scheduling, zone management, and cutting height adjustment are all straightforward. OTA firmware updates keep adding features.
The RTK accuracy is genuinely impressive. I watched it mow parallel lines with maybe 3cm of overlap — tighter than I could manage with a push mower.
Pros:
Cons:
Verdict: The best all-round robot mower in the UK right now. Wire-free convenience, proper AWD traction, and a polished app make it worth the investment for gardens up to 5,000m².

Segway's Navimow i2 AWD brings wire-free RTK navigation down to around £900 — significantly less than Husqvarna or Mammotion charge for comparable technology. Navigation accuracy is impressive for the price, delivering reliable positioning with neat parallel lines across the lawn.
AWD keeps it stable on slopes up to 35°. The 1,500m² coverage area handles the majority of UK gardens. Cutting height ranges from 30mm to 60mm, adjusted through the Navimow app. The app is clean and functional — not quite as polished as Mammotion's, but perfectly adequate.
The setup took 20 minutes. Walk the perimeter, tap 'save' in the app, and it was mowing. That's it. No wire, no pegs, no swearing.
The mower is relatively compact and lighter than the LUBA 2, leaving fewer tracks on soft ground. Where the i2 falls slightly short is obstacle detection — it relies on bump sensors rather than camera-based avoidance.
Pros:
Cons:
Verdict: The sweet spot for most UK homeowners wanting wire-free convenience without Husqvarna prices. Excellent value.

Husqvarna wrote the book on robot mowers. The 430X NERA uses EPOS satellite navigation with ultrasonic obstacle avoidance and systematic mowing. What sets it apart is handling genuinely difficult gardens — slopes up to 45%, multiple narrow passages, complex shapes with islands and paths running through.
The cutting quality is exceptional. Three pivoting razor blades produce a fine mulch that feeds back into the soil. Husqvarna's Automower Connect app is mature and feature-rich — GPS tracking, geofencing theft protection, mowing reports, and smart home integration.
At ~£3,000, the premium is hard to justify for simple rectangular lawns. But for complex gardens, Husqvarna's proven reliability and superior navigation make it the safer investment.
Pros:
Cons:
Verdict: The robot mower for difficult gardens. If you've got slopes, narrow passages, and a complicated layout, the 430X NERA handles it all.

At around £400, the Flymo EasiLife 200 is the most affordable route into robotic mowing. It's a boundary wire model designed for small lawns up to 200m². It uses a random navigation pattern — less efficient than systematic models, but for a small lawn it covers the entire area within its scheduled run time.
Cutting quality is decent for the price. Height adjustment ranges from 20mm to 50mm via the Flymo app over Bluetooth. Installation requires laying boundary wire around the perimeter — budget two to three hours for a small garden.
I set this up at my parents' house. Took about two hours for the wire, but they haven't touched a mower since. My dad said it's the best £400 he's ever spent.
Pros:
Cons:
Verdict: The entry point for robotic mowing. If your lawn is small and budget is tight, the EasiLife 200 keeps grass neat with zero ongoing effort.

The Worx Landroid M sits in productive middle ground at ~£600 for lawns up to 500m². Its standout feature is the modular accessory system — bolt on ACS ultrasonic sensors, a GPS module, voice control, or an off-road kit. Start with what you need and add later.
WiFi connectivity means control from anywhere via the app. The AI algorithm learns your garden's growth patterns to optimise scheduling. Edge cutting is better than average thanks to the blade extending close to the mower's side.
Pros:
Cons:
Verdict: A smart buy for the average UK garden. The modular system means you're not overpaying for features you don't need.

The YUKA 2000 is the only robot mower that produces genuine stripes, thanks to its rear roller and systematic parallel mowing pattern. It also collects clippings — a built-in sweeping system gathers cuttings into an onboard bin. For lawns that suffer from thatch, or if you prefer a clean finish, this is a significant advantage.
Navigation uses RTK + vision like the LUBA 2, delivering accurate wire-free coverage across 2,000m². The trade-off is more maintenance — you need to empty the collection bin regularly.
Pros:
Cons:
Verdict: The robot mower for lawn enthusiasts. If stripes and a clean finish matter, the YUKA 2000 delivers something no other robot can.

At just 57dB, the Gardena SILENO City 600 is the quietest mower on this list — quieter than a normal conversation. You can run it early morning, late evening, or during the day without disturbing neighbours. Coverage tops out at 600m², and it navigates passages down to 60cm.
The SensorCut system varies the mowing pattern to avoid visible tracks. Gardena's app connects via Bluetooth and WiFi (with optional gateway). The weather timer adjusts scheduling based on growth conditions.
Pros:
Cons:
Verdict: The best robot mower for smaller UK gardens where noise matters. Reliable, quiet, and well-supported.
Boundary wire models (Flymo, Worx, Gardena) cost less but require installing a perimeter wire — two to four hours depending on garden size. Wire-free models (Mammotion, Segway, Husqvarna) use satellite positioning and set up in 30 minutes via an app. If your budget stretches to £900+, go wire-free.
Check the slope rating carefully. Budget mowers handle up to 25%. AWD models manage 35°+. Husqvarna leads at 45%. Use a clinometer app on your phone if in doubt — gentle-looking slopes often exceed 25%.
For small gardens (under 100m²), a robot is a luxury. A cordless lawn mower takes 15 minutes. For medium gardens (100–500m²), the calculus shifts — 30+ hours of mowing per season eliminated. For large gardens (500m²+), a robot is transformative versus weekly sessions with a petrol mower or ride-on.
Robot mowers also improve lawn health. Cutting tiny amounts daily means clippings decompose rapidly, feeding nitrogen back into the soil. After a few months, the result is noticeably thicker, greener grass.
These robot mowers were strong contenders but narrowly missed out:
Seasonal tip: Robot mowers work best from March to October in the UK. Store yours in a dry shed over winter with the battery at 50% charge. This preserves battery health and keeps the electronics dry — two things that extend your mower's life by years.
Modern robot mowers have lift sensors, bump sensors, and recessed blades. The risk of injury is extremely low. Most owners schedule mowing during the night or while the garden is empty.
Yes, all seven models are weatherproof. However, mowing in heavy rain produces clumpy cuts and soft-ground tracks. Smart models pause during heavy downpours and resume when conditions improve.
Straightforward but time-consuming. A simple 200m² lawn takes one to two hours. A 500m² garden with obstacles takes three to four hours. Many retailers offer professional installation for £100–200.
All mowers have PIN protection. Premium models add GPS tracking and geofencing alarms. Husqvarna has the most comprehensive anti-theft system. Robot mower theft is relatively rare in the UK.
In two years of testing robots across multiple gardens, none have been stolen. The PIN lock and alarm are enough to deter opportunists, and let's be honest — a muddy robot mower isn't exactly easy to sell down the pub.
Expect eight to ten years with proper maintenance. Batteries retain 80% capacity after three to four years (replacements £80–150). Blades need replacing every two to three months (£10–20 per set). Motors and electronics last significantly longer.
