RYOBI ONE+ 18V 30cm 3-in-1 Mower Review: The Ultimate Space-Saving Solution for Small Gardens?

For years, my small urban garden felt more like a chore than a sanctuary. The patch of grass, no bigger than a large rug, was an awkward size—too small for a conventional lawnmower, yet too large to ignore. My shed was a chaotic graveyard of single-purpose tools: a cumbersome corded mower that was a nightmare to manoeuvre, a separate strimmer for the edges, and shears for the truly tight spots. Every time I wanted to tidy the lawn, it was a 20-minute ordeal of untangling cables, switching between tools, and feeling like I was using a sledgehammer to crack a nut. The frustration was real. A simple task became a cluttered, inefficient mess. I knew there had to be a better way to reclaim both my shed space and my sanity, a single, elegant solution designed specifically for the unique challenges of a compact garden.

What to Consider Before Buying a Cordless Rotary Mower

A cordless rotary mower is more than just a garden tool; it’s a key solution for achieving a neat, well-manicured lawn without the hassle of petrol fumes or the limitations of electric cords. Its primary benefit is freedom—the ability to move anywhere in your garden, navigating flowerbeds, trees, and garden furniture with ease. For owners of small to medium-sized lawns, these mowers offer the perfect balance of power, convenience, and low-maintenance operation, turning a weekend chore into a quick and satisfying task.

The ideal customer for this type of product is someone facing the challenges of limited storage space and the need for versatility. If your garden has intricate edges, pathways, and requires more than just a straight-line cut, a multi-functional tool can be a game-changer. Conversely, it might not be suitable for those with expansive lawns (half an acre or more), where the battery life and narrower cutting deck would become a significant limitation. For those larger spaces, a more powerful self-propelled petrol mower or a garden tractor would be a more practical investment.

Before investing, consider these crucial points in detail:

  • Dimensions & Space: The physical footprint of the mower is critical, both in use and in storage. Look for models with folding handles or vertical storage capabilities. The cutting width (e.g., 30cm) directly impacts how many passes you’ll need to make; a narrower deck is more manoeuvrable in tight spaces, while a wider one is more efficient on open patches of grass.
  • Capacity/Performance: Battery voltage (e.g., 18V, 40V) and capacity (measured in Amp-hours or Ah) are the lifeblood of a cordless mower. Higher voltage often means more power for tackling thicker grass. A higher Ah rating means longer runtime. Also, consider the cutting height adjustment; a single-lever system is far more convenient than adjusting each wheel individually.
  • Materials & Durability: Most modern cordless mowers feature a durable plastic deck, which is lightweight and rust-proof. While less robust than steel, it’s perfectly adequate for typical residential use. Pay attention to the quality of the wheels, handles, and adjustment levers, as these are the components you’ll interact with most.
  • Ease of Use & Maintenance: The beauty of battery power is the minimal maintenance. There’s no oil to change or spark plugs to replace. Consider the tool’s weight, ergonomic design of the handle, and how easy it is to start. For long-term care, keeping the underside of the deck clean and the blade sharp is all that’s typically required.

This review focuses on a unique contender in this space, but it’s important to understand the broader market. The best tool for you depends entirely on your specific needs and garden layout.

While the RYOBI ONE+ 18V 30cm 3-in-1 Mower is an excellent choice for a specific niche, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: A Clever Hybrid That Defies Convention

Upon unboxing the RYOBI ONE+ 18V 30cm 3-in-1 Mower, the first thing that struck us was its intelligent, modular design. It doesn’t look like a traditional mower. Instead, it presents as a robust grass trimmer that cleverly docks into a lightweight, wheeled mower deck. Assembly was refreshingly simple, taking less than five minutes without the need for any tools. You simply extend the trimmer shaft, click it into the deck, and you’re ready to go. The build quality, while predominantly plastic, feels solid and well-engineered, consistent with what we’ve come to expect from RYOBI’s ONE+ range. The iconic hyper-green and grey colour scheme is instantly recognizable. Weighing in at a mere 8 kilograms, it feels incredibly light and manageable, a stark contrast to the hefty machines I was used to. The initial feeling is one of intrigue; it’s a tool that promises to solve multiple problems, and we were eager to see if its performance could live up to its clever concept. You can see its full feature set and innovative design here.

What We Like

  • Incredibly versatile 3-in-1 design (mow, trim, edge) saves space and money.
  • Extremely lightweight and easy to manoeuvre in tight spaces.
  • Seamless transition between modes via a simple foot pedal.
  • Excellent for small gardens, especially for users already in the RYOBI ONE+ ecosystem.

Limitations

  • Not suitable for lawns larger than 100-150 square metres.
  • Handle connection to the trimmer body can feel slightly wobbly under pressure.

In-Depth Performance Analysis: Putting the 3-in-1 to the Test

A tool that claims to do three jobs often excels at none. We went into this test with healthy scepticism, expecting compromises. Over several weeks, we put the RYOBI ONE+ 18V 30cm 3-in-1 Mower through its paces on a small lawn with tricky borders, overgrown patches along a fence, and a gravel path that constantly sprouted weeds. This is where we separate the marketing claims from the real-world performance.

From Mower to Edger in Seconds: The Genius of the 3-in-1 System

The core appeal of this machine is its chameleon-like ability to transform, and we can confirm it is brilliantly executed. The transition from mower to trimmer is the main event. A large, ergonomic foot pedal on the mower deck releases the trimmer unit with a satisfying click. You simply lift it out, and you have a fully functional line trimmer in your hands. There’s no faffing, no tools, just a seamless switch that takes less than five seconds. This is a legitimate game-changer for workflow in a small garden. We could mow the main patch, and upon reaching the edge of a flowerbed, pop the trimmer out, tidy the border, and dock it back in to continue mowing without missing a beat.

The third function, edging, is just as intuitive. A button on the trimmer shaft allows the head to pivot 90 degrees. This turns it into a precision edger, perfect for creating those sharp, clean lines along driveways and paths. We found the ergonomics in trimmer/edger mode to be excellent. The handle is comfortable, and the shaft is telescopic, allowing users of different heights to find a comfortable working position. This was a point praised by several users, with one noting it was “well ergonomic, comfortable handle, adjustable telescopic to lengthen the tool.” The convenience this single unit offers is hard to overstate. It replaces three separate tools, liberating an incredible amount of shed space—a benefit another user highlighted, stating that once folded, it “becomes really convenient to store.” For anyone battling clutter, this space-saving feature alone is worth the price of admission.

Compact Power: Cutting Performance and Battery Efficiency

With a 30cm cutting width, the RYOBI ONE+ 18V 30cm 3-in-1 Mower is squarely aimed at smaller lawns. In mower mode, it performs admirably. We tested it with a 5.0Ah ONE+ battery, and the brushless motor delivered surprisingly robust power, slicing through moderately long and slightly damp grass without bogging down. It’s not designed for hacking through a wild meadow, but for regular maintenance of a domestic lawn, the power is more than sufficient. One user happily confirmed this, noting the “good power of the Brushless motor” and that a 5Ah battery was “well sufficient” for their small garden.

The single-point height adjustment is another fantastic feature. A large lever on the deck allows you to choose from four cutting heights, ranging from 43mm to 88mm. This makes it incredibly easy to adapt to different grass lengths throughout the season. The cut quality is clean and even, leaving a tidy finish. It is important to set realistic expectations, however. As one tester from Germany rightly pointed out, while it works well, they “wouldn’t want to mow the specified 100 square meters” with it, as it’s better suited as a primary trimmer that can also mow. We agree. Its sweet spot is for lawns up to about 100 sq m where manoeuvrability and edge work are just as important as the main cut. For those specific conditions, its performance is spot-on.

Ergonomics and Build Quality: Living with the RYOBI

Living with a tool day-to-day is about more than just raw power; it’s about how it feels to use. At just 8kg, the RYOBI ONE+ 18V 30cm 3-in-1 Mower is incredibly nimble. Pushing it around the lawn is effortless, and navigating tight corners or garden obstacles is a joy compared to heavier, bulkier mowers. The lightweight design makes it accessible to a wider range of users who might struggle with traditional machinery. The handle design is comfortable, and the controls are intuitive and well-placed.

The construction is primarily a tough plastic, which keeps the weight down and eliminates any worries about rust. While generally solid, we did notice the same minor issue one user reported: the connection point where the handle shaft joins the main trimmer body can feel a little “wobbly” if you apply a lot of twisting force. During normal use, this was not an issue and didn’t impact performance, but it’s a point of mechanical flex worth noting. It doesn’t feel like it will break, but it lacks the rock-solid feel of a dedicated, high-end single-purpose tool. This is a minor trade-off for the immense versatility and modularity on offer. Furthermore, the ability to store the unit vertically is a huge plus, making it easy to tuck away in a narrow space. This thoughtful design proves that RYOBI understands its target audience: those for whom space and convenience are paramount. Its thoughtful ergonomic design is a feature that really sets it apart.

What Other Users Are Saying

Our positive experience with the RYOBI ONE+ 18V 30cm 3-in-1 Mower is echoed by a broad consensus among users. The overwhelming sentiment is one of pleasant surprise at its practicality and effectiveness. Many, like one French user, purchased it primarily for its trimming and edging capabilities but found the “mower accessory is super too!” The convenience of the ONE+ battery system is a recurring theme, with owners of other RYOBI tools celebrating the ability to use their existing batteries and chargers.

Positive comments frequently centre on its lightweight nature, manoeuvrability, and excellent storage potential. An Italian reviewer praised it as “Light, easy to adjust, ergonomic,” specifically complimenting the modern lever system for handle adjustment. However, the feedback is also balanced. The most common critique, which we also observed, comes from a German user who noted that the “connection from the handle to the lower part is now already wobbly.” While they still found the machine worked well, it raises a valid question about long-term durability under heavy use. This feedback reinforces our assessment: it’s a brilliant and well-designed tool for its intended purpose—small lawns and complex gardens—but it may not be robust enough for those who are rough on their equipment.

How Does the RYOBI Compare to the Alternatives?

The RYOBI ONE+ 18V 30cm 3-in-1 Mower occupies a unique niche, but how does it stack up against more traditional cordless mowers in a similar price and size bracket? Here, we compare it against three popular alternatives to help you decide.

1. Yard Force 40V Cordless Lawn Mower 32cm

The Yard Force mower is a more conventional, dedicated rotary mower. Its key advantages are the more powerful 40V battery system and the inclusion of a rear roller for creating those classic lawn stripes. With a slightly wider 32cm cutting width and a 30L grass collector, it’s geared more towards pure mowing efficiency on small to medium lawns. If your primary need is a pristine, striped finish on an open patch of grass and you already have a separate trimmer and edger, the Yard Force is a formidable choice. However, it lacks the all-in-one versatility and supreme space-saving design of the RYOBI.

2. Einhell GE-CM 18/30 Li Cordless Lawnmower

The Einhell is perhaps the most direct competitor to the RYOBI in its mower-only function. It operates on the popular 18V Power X-Change battery platform, making it an attractive option for those already invested in the Einhell ecosystem. It matches the RYOBI’s 30cm cutting width and also features a brushless motor for efficiency. It is, however, a dedicated mower. You would still need to purchase and store a separate tool for trimming and edging. Choose the Einhell if you want a no-frills, reliable, compact mower and prefer its battery system, but opt for the RYOBI ONE+ 18V 30cm 3-in-1 Mower if you crave the incredible consolidation of three tools into one.

3. Hyundai Electric-Start Self-Propelled Petrol Lawnmower

We’ve included the Hyundai to highlight the difference in category. This is a petrol-powered, self-propelled beast with a 42cm cutting width, designed for medium to large lawns where power and efficiency are paramount. It’s in a different league in terms of performance, but also in terms of weight, noise, maintenance, and storage requirements. This mower is for someone with a substantial garden who values raw power over finesse. It serves to underscore the RYOBI’s mission: it is not trying to compete with large petrol mowers. Instead, it offers a smart, lightweight, and versatile solution for the specific challenges of smaller, more intricate spaces.

Final Verdict: A Niche Product That Hits a Home Run

After extensive testing, we can confidently say that the RYOBI ONE+ 18V 30cm 3-in-1 Mower is a brilliantly conceived and well-executed tool that perfectly serves its target audience. It is not trying to be a one-size-fits-all solution for every garden. Instead, it is an elegant and highly effective problem-solver for those with small lawns, complex edges, and limited storage space. The seamless transition between mowing, trimming, and edging is not a gimmick; it’s a genuinely useful innovation that streamlines the entire process of lawn care.

While it may not be the most powerful mower on the market, and there are minor questions about the long-term rigidity of its handle connection, these are small trade-offs for its incredible convenience and versatility. For anyone already invested in the RYOBI ONE+ battery platform, this tool is an absolute must-have. For those new to the system, it represents a compelling reason to jump in. If you’re tired of a cluttered shed and the hassle of juggling multiple tools for your small garden, this is the clever, all-in-one solution you’ve been waiting for. We wholeheartedly recommend it.
