UK garden reality check
Two gardens with the same lawn size can behave very differently. Clay-heavy lawns (common in areas like Greater Manchester and West Yorkshire) are more prone to wheelspin and turf marking in wet spells. Free‑draining soils seen in parts of Surrey and Kent can be more forgiving. If you’re unsure, an installer can confirm what matters in your specific garden.
The straight answer
Usually, yes — but only if the mower type matches your layout. In the UK, the biggest deal‑breakers are steep slopes, narrow passages, heavy tree cover (for some wire‑free systems), and uneven ground that causes wheelspin or scalping.
Robot mowers are at their best when you let them do what they’re designed for: frequent light cuts that keep the grass consistently short. If you expect a once‑a‑week ‘rescue mow’ in long, wet grass, you’ll be disappointed.
This guide helps you quickly identify whether your garden is a good fit, what to measure before you buy, and what installers look for when they assess suitability.
Quick suitability check (2 minutes)
A robot mower is usually a good fit if: (1) the lawn is mostly continuous, (2) you can place a charging station with reliable power, and (3) your grass isn’t routinely boggy for long periods.
It may be a poor fit if: you have steep banks near hard edges, the lawn is heavily rutted, or it’s split into separate areas with no safe way for the mower to travel between them.
Don’t get stuck on brand names at this stage. The highest‑impact variables are slope, shape, tree cover, and edges — because those are what cause real‑world failures.
Not sure if your garden is suitable?
Most robot mower headaches come from mismatching the mower type to the layout. A quick assessment can save you money and frustration.

What matters in UK gardens (and why)
UK gardens tend to combine compact footprints with fiddly edges: curved borders, raised beds, patio steps, narrow side returns and drainage dips. These create ‘decision points’ where a mower either glides through or gets stuck repeatedly.
Clay‑heavy soils also change the game. Even a modest incline can become slippery after a wet week, and repeated turns on soft ground can leave light wear marks. Good setup mitigates this — but it’s not magic.
Finally, shaded lawns under trees or next to tall buildings matter more than people realise. Shade affects growth patterns and drying time, and for some wire‑free systems it can also affect positioning reliability.
Slopes: understand percentage ratings properly
Manufacturers often state slopes as a percentage. A 30% slope is steeper than many people expect — and it’s not only the climb that matters. Turning on a slope is where wheelspin usually starts.
Real‑world performance depends on traction and conditions. Wet grass on clay can turn a ‘within spec’ slope into a problem. If you’re near the limit, build in margin: choose a mower with stronger hill performance and install to avoid tight turns on the steepest section.
Installers often adjust boundary offsets on slopes to prevent the mower drifting into borders or repeatedly failing at a choke point.
Trees, shade and wire‑free navigation
Wire‑free systems can be excellent in open gardens, but dense canopy and tall buildings can weaken satellite reception. The symptoms aren’t always dramatic — you might see slower mapping, missed edges, or occasional ‘no position’ errors in specific corners.
If most of your mowing area sits under heavy tree cover, a boundary wire setup can still be the most dependable option. It isn’t as exciting, but it’s robust because it doesn’t care about satellite visibility.
A practical approach is a quick feasibility check: where can an antenna/base station go, what’s the line of sight to the sky, and are there dead zones that would need stay‑out areas or different routing?
Narrow passages and tricky shapes
Tight corridors are common in UK side returns. They’re also where many robots waste time: bouncing off borders, turning too early, or repeatedly ‘choosing’ the same route and missing patches elsewhere.
For narrow passages, installation matters more than the mower. Correct boundary offsets, sensible guide paths (for wired systems), and zone settings can turn a frustrating setup into a reliable one.
If your garden has a lot of tight edges, treat professional installation as an insurance policy — it’s usually cheaper than weeks of trial‑and‑error.
Uneven lawns, molehills and bumpy ground
Small bumps are fine. Problems start when the mower bottoms out, loses traction, or scalps high spots. Typical culprits: deep dips, ruts, rabbit scrapes, repeated molehills, and poorly filled trenches from past garden work.
The simplest fix is lawn prep before installation. Levelling the worst dips, dealing with persistent mole activity, and improving drainage in chronic wet spots can dramatically improve reliability.
If you want a ‘set and forget’ experience, the garden has to be at least somewhat ‘robot‑friendly’. That doesn’t mean perfect — it means predictable.
Edges: set expectations (and avoid disappointment)
Edge cutting has improved, but ‘perfect edges with zero trimming’ is still unrealistic for many UK gardens — especially with raised borders, brick edging, narrow strips, or lawns that meet gravel.
A good install reduces missed strips by setting boundary offsets carefully and designing safe routes. But for many gardens, occasional edging is still part of ownership.
If edge perfection is your top priority, say that up front when getting quotes. It changes the recommendation and the installation approach.

What to measure before you get quotes
You don’t need engineering drawings. To get accurate recommendations, collect: (1) approximate lawn area (m²), (2) steepest slope, (3) whether you have multiple zones, (4) whether tree cover is heavy over the mowing area, and (5) where power is available for a charging station.
If you don’t know the exact m², a rough rectangle estimate is fine initially. Installers can refine it on‑site.
A couple of photos of the trickiest parts (slope, narrow passage, wet corner) often help more than a perfect measurement.
When professional installation is worth it
DIY can work on simple, flat lawns. But if you have steep sections, multiple zones, narrow passages, or you’re choosing wire‑free and you’re not confident about signal conditions, professional installation usually pays for itself in fewer call‑outs and fewer ‘rescues’.
A good installer also helps with theft prevention setup, safe mowing schedules (including wildlife considerations), and ongoing maintenance expectations.
If you’re aiming for reliability, not a weekend project, professional installation is the shortcut.
Next step: a quick suitability check
If you’re still unsure, don’t guess. A short assessment can confirm whether wired or wire‑free is best for your garden and what budget range is realistic.
It’s also the fastest way to avoid buying the wrong capacity mower or placing the charging station somewhere that causes docking failures.
Get 3 quotes and ask each installer to explain their recommendation in plain English. If they can’t, that’s a useful signal.
Most common installation issues in UK gardens
- Wheelspin on damp clay (especially where the mower turns tightly on slopes or soft patches).
- Docking failures caused by a charging station placed on a slope, in a tight corner, or on ground that turns muddy.
- Boundary problems after landscaping (wire cuts, loose joins, or boundaries set too tight to edges).
- Narrow passages where the mower wastes time turning or repeatedly “chooses” the same route.
- Unrealistic edge expectations in raised-border gardens (many still need occasional trimming).
What installers assess on a site visit
A good installer will measure the steepest slope, check drainage and soil softness, identify choke points (narrow passages, tight corners), and confirm the safest charging station location. If you’re comparing installers, use the dealer directory and ask each one to explain their plan for your trickiest area in plain English.
Manufacturer and model reality (neutral)
Different manufacturers optimise for different constraints (traction, navigation, boundary behaviour). For example, some models from Husqvarna are well known for handling more demanding gardens — but suitability still comes down to your layout, soil, and installation quality.

FAQ
What’s the biggest reason robot mowers ‘don’t work’?
Bad installation and unrealistic expectations. Most recurring issues come from boundary placement, poor docking access, or terrain problems that weren’t addressed before installation.
Can a robot mower cross a path or driveway?
Sometimes, but it needs planning. Some setups use defined crossings; others require carrying the mower between zones. An installer can advise based on the surface and safety.
Do I need to prep the lawn first?
If you have ruts, molehills, or chronic wet patches, a bit of prep prevents most ‘stuck’ problems. Simple levelling and drainage tweaks are often enough.
Do I need Wi‑Fi for a robot mower?
Not necessarily. Many use Bluetooth for setup and work independently day-to-day. Some features (app control, alerts, updates) may work better with Wi‑Fi or mobile coverage, depending on model.
Will it replace edging completely?
Usually not. Many gardens still need occasional edge trimming, especially with raised borders, brick edging, or narrow strips the mower can’t reach safely.
Is professional installation worth it?
If you have slopes, multiple zones, narrow passages, or you want wire-free, professional installation usually reduces call-outs and improves reliability.
