Are you looking for a robotic lawn mower that's under £350? Discover the best budget-friendly garden robots that trim your grass without draining your wallet. Perfect for smaller gardens, first-time buyers, and people who'd rather watch a mower at work than push one.
Budget Bots That Actually Get the Job Done
Robot lawn mowers used to be exclusive gadgets for the sort of people who say things like "My Tesla is charging" or "I'll have the truffle risotto." But the good news is, the robots have come down from the luxury shelves and joined the rest of us in the land of sensible budgets. Yes, you can now have your lawn cut automatically for under £350, which is roughly the price of a fancy dinner, a weekend hotel stay, or two months of pretending you'll actually use a gym membership.
Simpler Smaller Gardens
These more budget-friendly models are targeted primarily for smaller gardens, simpler lawn shapes, and people who just want something that cuts the grass without needing a PhD in robotics. They are not intended for huge country estates, steep slopes, or lawns shaped like modern art. Think compact suburban patches, neat rectangles, or modest back gardens which currently rely on your goodwill and occasional guilt to stay tidy.
Lower-Priced Options That Still Wow
Budget does not have to mean bare bones. Many of these models offer app control, mulching, rain sensors and surprisingly decent cutting performance. They may not map your garden with AI or leap over tree roots like an Olympic athlete, but they're dependable, fuss-free and built for the everyday homeowner.
Who These Mowers Are For
- People who want a robotic mower but not the robotic mower price
- Small garden owners who prefer relaxing over wrestling with a manual mower
- First-time robot mower buyers looking to "try before they upgrade
- Anyone who wishes to decrease weekend chores without decreasing bank balance
Who They’re Not For
- Lawns over 500 m²
- Steep gardens that double as ski slopes
- Tech addicts seeking satellite mapping, LIDAR, AI vision, and weather predictions
- Expecting Rolls-Royce-type build quality with a bus ticket budget
Best 3 Robotic Mowers Under £350
#1, LawnMaster 16cm Cordless Robotic Lawnmower 24V
The Budget Bot With Surprisingly Big Ambition. The LawnMaster 24V is that robotic mower equivalent of the friend who turns up in a tiny car but somehow fits an entire IKEA bookshelf in the back. Compact, unassuming, and usually found floating around the £300 mark, this mower punches way above its price tag, especially for small, well-defined UK lawns.
Of course, the standout feature is its wire-free operation: no boundary wires, no garden archaeology, no three-hour instruction manual meltdown. The LawnMaster simply uses its camera and grass-detection sensors to figure out where your lawn starts and stops, which feels a bit like magic, but with fewer rabbits involved. Charge the detachable lithium battery, plop the mower down on your turf, and let it buzz around like a happy green Roomba.
It cuts in a random pattern, which sounds chaotic but works perfectly for smaller areas, especially given its huge 240-minute run time. Four hours of mowing on one charge is outrageous at this price point. Add the steel rotary blade, adjustable cutting heights from 2cm to 6cm, mulching feature and spiral spot cutting mode for patchy areas, and you've got a genuinely smart little helper.
At just 6.6kg, it’s light enough to move with one hand, and its 1-hour charge time makes it one of the quickest-in-class to get back out working. If your lawn is basically a neat, fenced-in rectangle without cliffs, moats or dense forest, this is one of the best-value robotic mowers in the UK right now.
The LawnMaster is a cracking bit of kit that proves affordability does not equate with "can't be bothered" for someone with a small garden and a tight budget.
#2, Yard Force MB400 Robotic Cordless Lawnmower
A Slightly Pricier Bot That Thinks It's Premium. The Yard Force MB400 is the mower for people who want something a bit more serious but not too serious. Normally sitting around the £330-350 mark, it does drop below when sales roll in, which still makes it fair game for the budget-friendly list. with an asterisk. Let's call it the "posh cousin" of the under-£350 category.
The Husqvarna offers a slightly more traditional robotic setup, with a charging station complete with its own weather cover that makes it look like it has its own tiny bus shelter. It uses a steel blade for a clean, tidy cut, and offers three cutting heights between 2cm and 5.5cm, adjustable with a simple rotary knob on top. No faffing, no apps required - just twist and go.
Speaking of apps, it does come equipped with Bluetooth scheduling so that you can control your mower from your phone, just like a lazy Bond villain. It has a shorter runtime at 60 minutes, with a 1.67-hour recharge, but this still works fine for small to medium-sized gardens, especially when you let it run little and often.
It weighs 8.2kg, so it's still light enough to lift up without inadvertently discovering new muscles. In actuality, the mulching feature is handy, turning clippings into natural lawn feed, and that 2-year guarantee gives you peace of mind.
The Yard Force MB400 is ideal for anyone who wants a more polished robot experience without jumping into the £600–£1,000 category. If the price dips into the £300s during some sale, it becomes an absolute bargain. If not, it’s still a strong performer, just a little outside the strict “cheap bot” bracket.
#3, WORX WR169E Landroid Robotic Lawn Mower
Meet the pint-sized genius with a taste for narrow spaces. If robotic mowers did IQ tests, the WORX WR169E would be that annoyingly clever kid who finishes before everybody else and then asks the teacher for more homework. Packed full of AIA Artificial Intelligence Algorithm technology, this little black lawn ninja cuts through narrow passages so elegantly you'd swear it was reared in a maze.
Despite its budget-friendly price tag - usually somewhere between £300 and £350 - the Landroid S300 acts as if it is on a far fancier list: app-controlled, self-charging, multi-zone capable. whether your garden is neatly arranged or more "creative chaos", it'll find its way around without sulking.
The cutting performance is sharp and neat, even refined, courtesy of its 3-blade pivoting system. The blades rotate both forward and backward, which is basically mower talk for "I last twice as long, thank you very much". Its 16 cm cutting width suits lawns up to 300 m², making it a proper contender for small-garden owners who want the perks of a premium robot without the premium price.
Rain sensor? Yes. Safety sensor? Absolutely. Mulching system? Of course. Plus, it politely docks itself when it needs a recharge, the same way you wish your teenager would return home without being reminded fourteen times.
The installation service, while expensive at £250, will be a godsend for anyone who breaks out in a cold sweat at the very sight of boundary wire. But do you need it? Probably not, unless your lawn resembles a Mario Kart level.
In a nutshell, the Landroid S300 is smart, compact, and just right for small gardens where agility and efficiency count more than brute force or cutting width.
Conclusion
Buying a robotic mower for less than £350 used to mean accepting something that looked and behaved like a slow, confused Roomba with a drinking problem. But times have changed, technology has leveled up, and budget robot mowers have gone from "gimmicky garden toys" to "legitimate grass-cutting heroes."
All three models in this shortlist bring great value for money, each suited to slightly different garden sizes, user personalities, and levels of tolerance for boundary-wire DIY. Whether you've got a compact garden or a busy lifestyle-or you just never want to push a mower again-these lower-range options won't break the bank.
Simplicity
The single biggest advantage of choosing a budget robotic mower can be summed up with one word: consistency. These machines aren't built to impress your neighbours with either their speed or noise; they're built to quietly nibble at your lawn all week until grass stops being a chore and turns into something you barely think about.
If you can live with a slightly smaller cutting width and the odd bit of app tinkering, then the sub-£350 category is absolutely worth diving into. You'll save time, save effort and probably save your relationship, since nothing starts a domestic argument quite like deciding whose turn it is to mow.
Final Word
Whether you go for the clever tech of the Landroid, the simplicity of a more basic model, or the all-round practicality of either of the options 1 and 2, your grass is about to enjoy its best year yet, and your weekends are about to get significantly lazier.
