RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit Review: The Ultimate Cord-Free Convenience Test

There’s a familiar Sunday morning ritual for many of us: wrestling a heavy, petrol-guzzling mower from the shed, fumbling with the pull-cord, and then enduring the deafening roar that shatters the neighbourhood peace. Or perhaps it’s the tedious dance of the electric cord – constantly flicking it over your shoulder, untangling it from rose bushes, and living in perpetual fear of accidentally mowing over it. For years, this was the accepted price of a tidy lawn. We’ve been on a mission to find a better way, a solution that brings genuine convenience and quiet efficiency to garden maintenance. The dream is simple: a lightweight, powerful, and cord-free experience that turns a chore into a pleasure. This is precisely the promise of the RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit, a bundle that aims to solve not one, but two of our biggest gardening headaches in a single, battery-powered package.

What to Consider Before Buying a Cordless Rotary Mower

A cordless rotary mower is more than just a tool; it’s a key solution for reclaiming your weekend and maintaining your outdoor space with minimal fuss. The primary benefit is freedom. Freedom from the tether of a power cord, freedom from the fumes and maintenance of a petrol engine, and freedom from the excessive noise that accompanies traditional mowers. This technology allows you to tackle any corner of your garden with ease, navigating around trees, flowerbeds, and garden furniture without a second thought. For those with multiple, separated patches of grass, it’s a game-changer, eliminating the need for long and cumbersome extension leads.

The ideal customer for this type of product is a homeowner with a small to medium-sized lawn, typically up to around 200 square metres. It’s perfect for someone who values convenience, low maintenance, and quieter operation. If you have mobility concerns, suffer from a bad back, or simply dislike wrestling with heavy machinery, the lightweight nature of most cordless models will be a revelation. This kit, in particular, appeals to those looking for a complete lawn care solution out of the box. However, it might not be suitable for those with vast, sprawling estates or fields where the sheer scale demands the unrelenting power and runtime of a large petrol mower. Similarly, if your lawn is severely overgrown with thick, wet, and tangled grass, an entry-level battery mower may struggle with the initial reclamation cut.

Before investing, consider these crucial points in detail:

• Dimensions & Space: The cutting width (or deck size) is paramount. The 33cm deck on this Ryobi is ideal for manoeuvring in smaller, more intricate gardens. A larger deck cuts faster in open spaces but can be clumsy around obstacles. Also, consider storage. Models with folding handles and collapsible grass boxes, like this one, are a blessing for those with limited shed or garage space.
• Capacity/Performance: Battery life is the single most important factor. It’s measured in Amp-hours (Ah); a higher number generally means a longer runtime. The included 4.0Ah battery is a decent starting point, but you must match it to your lawn size. Grass box capacity, here a respectable 35 litres, determines how often you have to stop to empty clippings, directly impacting how quickly you finish the job.
• Materials & Durability: Most cordless mowers feature a robust plastic deck and housing. This is a deliberate design choice to keep the weight down, making them easier to push and lift. While not as rugged as a steel-decked petrol mower, they are more than durable enough for typical domestic use and are resistant to rust.
• Ease of Use & Maintenance: Look for features like single-point height adjustment, which allows you to change the cutting height with one lever instead of adjusting each wheel individually. Maintenance is minimal compared to petrol models; simply keep the underside clean, ensure the blade is sharp, and charge the battery. The simplicity is a major selling point.

While the RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit is an excellent choice, 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: Unboxing an All-in-One Lawn Care System

The box arriving with the **RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit** feels surprisingly light, a promising first sign. Inside, the components are neatly packed and protected. Our first thought, echoed by many user experiences, was how refreshingly simple the assembly process is. The picture-based instructions can be a little cryptic, but intuition serves you well; we had the lawnmower fully assembled in under 15 minutes. The handles click into place, the grass box clips together, and you’re ready. The grass trimmer requires a single Phillips screwdriver to attach the safety guard, a task of about two minutes.

Holding the tools, the signature Ryobi lime green and grey aesthetic is present and feels modern. The lawnmower itself, at under 12kg, is incredibly lightweight. We could easily lift it with one hand, a stark contrast to the hefty petrol mowers of old. This immediately brings to mind users who mentioned needing to carry their mower up steps or those with arthritis who praised its lack of heft. The trimmer feels similarly light, though some might initially perceive this as “flimsy.” In our hands-on testing, we found it to be a trade-off for user comfort and reduced fatigue during longer edging sessions rather than a lack of quality. To get started, we popped the 4.0Ah battery on the intelligent charger base, which brought it to full power in about an hour, and we were ready to see if this kit could live up to its promise. You can see the full kit and its components here.

Deep Dive: Performance of the RYOBI 18V ONE+ Cordless Kit in the Real World

A spec sheet can only tell you so much. To truly understand a product, you have to put it to work. We spent several weeks testing the **RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit** on a variety of lawn types and conditions, from neat ornamental grass to a slightly neglected back garden. Our goal was to push it beyond a simple tidy-up and see where its strengths and limitations truly lie. What we discovered was a surprisingly capable and thoughtfully designed system that punches well above its weight, albeit with one significant caveat that every potential buyer needs to understand.

The Mowing Experience: Lightweight Agility Meets Cutting Finesse

Pushing the lawnmower for the first time is a genuinely pleasant surprise. Its low weight means it glides across the lawn with minimal effort. For anyone used to self-propelled petrol mowers, this manual push mower feels even easier to handle due to its sheer lack of mass. We found ourselves weaving around garden ornaments and along curved borders with an agility that heavier mowers simply can’t match. This confirms the feedback from numerous users, particularly those with back problems or arthritis, who found it joyous to use.

The 33cm cutting deck is perfectly suited for small to medium lawns. On our test patch of around 120 square metres, it made quick work of the main area. The single-point height adjustment is, in theory, a premium feature. A single lever controls all four wheels, offering five cutting positions from a close 25mm to a forgiving 65mm. While fantastically convenient, we did find, as some users noted, that the lever can be quite stiff. It requires a firm hand to operate, sometimes needing you to hold the mower deck steady with your other hand. Once you get the knack, it’s fine, but it lacks a certain smoothness.

The cut quality itself is clean and consistent on a regularly maintained lawn. The EasyEdge grass comb feature is a standout. These small plastic combs on the side of the deck work to pull in blades of grass right up to the edge of a wall or fence, significantly reducing the amount of trimming needed afterwards. It’s a small detail that makes a big difference. We also tested the included mulching plug, a feature often omitted at this price point. It works effectively, chopping the clippings finely and returning them to the lawn as a natural fertiliser. However, as with any mulching mower, this is best used on dry, shorter grass to avoid clogging the deck.

The Grass Trimmer: The Perfect Partner for Crisp Edges

Often, the trimmer included in a kit like this can feel like an afterthought. That is not the case here. The 25cm grass trimmer is a capable tool in its own right and the perfect companion to the mower. It shares the same lightweight design philosophy, making it comfortable to hold and use for extended periods. The auto-feed line system worked reliably in our tests, advancing the cutting line with a simple tap on the ground.

The star of the show, however, is its EasyEdge functionality. With a quick press and twist, the entire head rotates 90 degrees, transforming the tool from a horizontal trimmer into a vertical edger. We found this transition to be smooth and intuitive. Running it along the edge of a pavement or driveway created a sharp, professional-looking finish that really tidies up the whole look of the lawn. As one user aptly put it, the handle turning “a full 180° smoothly to make strimming edges of pavement an easy job” is a fantastic feature. The power is more than sufficient for cutting through standard grass and common weeds, providing the perfect finishing touch after the main mow is complete. It really completes the lawn care package offered by the RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit.

The Elephant in the Room: Battery Life and the ONE+ Ecosystem

This is the most critical aspect of the **RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit** and the source of the most divided user opinions. The kit comes with a single 4.0Ah 18V ONE+ battery. Our testing sought to find a definitive answer: is it enough? The answer is: it depends entirely on your lawn.

On our smaller test lawn (approx. 120 sq m) that was cut two weeks prior, we managed to mow the entire area and then trim all the edges on a single charge, with one out of four bars of battery life remaining. This aligns with users who reported being “perfect for a medium sized garden.” However, we then tackled a slightly larger lawn (approx. 180 sq m) that was more overgrown. The mower had to work harder, and the battery was depleted before the mowing was even finished. This confirms the experience of users who found the battery lasted only “15 minutes” and required multiple recharges. It also struggles more in damp conditions, as the motor has to work harder, draining the battery faster. One user astutely noted, “This Mower is more for the regular cut than leaving it for a long time.” We couldn’t agree more.

Our expert verdict is this: the included 4.0Ah battery is adequate for small gardens (up to 150 sq m) that are mown weekly. For anything larger, or if you often let your grass get long between cuts, you should consider the purchase of a second battery an essential, not optional, expense. This is where the true strength of the RYOBI ONE+ system shines. If you already own other Ryobi tools, you likely have spare batteries ready to go. If you’re new to the system, buying this kit is an excellent gateway into a vast range of over 200 tools that all share the same battery, a feature that provides immense long-term value.

Smart Design, Easy Storage, and User-Friendly Touches

Beyond the core performance, Ryobi has included several design elements that enhance the overall user experience. The lawnmower’s handle is ergonomic and offers three different height positions, making it comfortable for users of all statures. After use, the handles fold down completely flat with quick-release levers, and the 35L grass catcher is fully collapsible. This transforms the mower into a compact, storable package that can be tucked away on a shelf or stood vertically against a wall, a huge benefit for those with cramped sheds. The grass catcher itself is easy to attach and remove, and we found it collected clippings efficiently. One hilarious but important piece of user feedback we must confirm: you must remove the black plastic mulching plug from the grass chute before attaching the collection bag! One user admitted their error, wondering why it hadn’t collected any grass—it’s an easy mistake to make, but crucial for proper bagging.

What Other Users Are Saying

Across the board, the feedback on the **RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit** highlights a consistent set of themes. The overwhelming positive sentiment revolves around its lightweight design and ease of use. One user, who suffers from arthritis in both knees and thumbs, specifically noted it was “easy to use and push about,” calling the lightness “joyous.” This sentiment is echoed by many who were looking to move away from heavy petrol or cumbersome corded mowers.

The value proposition of getting two effective tools in one bundle is another frequently praised aspect, especially for those already invested in the ONE+ battery platform. As one Ryobi fan stated, “I already had several batteries and a charger making the mower great value for money.”

However, the negative feedback is just as consistent and centres almost exclusively on battery performance with the single included 4.0Ah unit. A frustrated user reported, “The battery lasts 15 minutes and takes about an hour to recharge,” forcing them to spend more time waiting than mowing. Another user with a modestly sized front garden noted it took three full charges to complete the job. This feedback is crucial; it doesn’t suggest the mower is faulty, but rather that user expectations for battery life must be aligned with their garden’s size and condition.

How Does the RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit Compare to Alternatives?

The cordless mower market is competitive, and while this Ryobi kit offers fantastic value, it’s important to see how it stacks up against other popular options. We’ve selected three distinct alternatives to help you decide if the Ryobi is the right fit for you.

1. Greenworks 48V 36cm Cordless Lawnmower 2x2Ah Batteries

The Greenworks G24X2LM36K2X is a step up in terms of raw power. By using two 24V batteries simultaneously to deliver 48V, it offers more torque for tackling tougher, denser grass. It also has a slightly wider 36cm cutting deck and a larger 40L grass bag, making it more efficient for medium-sized lawns (up to 210m²). If your lawn is on the larger side of small, or you often find yourself cutting grass that’s a bit longer than you’d like, the extra power of the Greenworks model could be a significant advantage. However, it comes as a mower-only package and you’ll be buying into a different battery ecosystem, making the Ryobi twin kit the better value option if you need a trimmer too.

2. BOSCH AHM 38 G Lawn Mower

The Bosch AHM 38 G represents a completely different approach to lawn care. As a manual cylinder mower, it uses no electricity or petrol, making it the ultimate eco-friendly and silent option. It provides a scissor-like cut that is healthier for the grass blades than a rotary action. This is an excellent choice for those with very small, flat, and well-maintained lawns who enjoy the light exercise and simplicity it offers. It is significantly cheaper and requires virtually no maintenance. However, it’s unsuitable for uneven ground, long grass, or anyone who doesn’t want to provide the power themselves. It’s a specialist tool, whereas the Ryobi is a versatile all-rounder.

3. Einhell GE-CM 18/30 Li Solo Cordless Lawnmower

The Einhell GE-CM 18/30 Li is perhaps the most direct competitor to the Ryobi mower. It’s also an 18V cordless model from a brand with a popular shared battery platform (Power X-Change). The Einhell is slightly more compact, with a 30cm cutting width and a 25L grass box, making it better suited for very small or complex gardens. It’s often sold as a “body only” unit, which is a fantastic budget option for someone who already owns Einhell 18V batteries and a charger. If you have a very small lawn and are already in the Einhell ecosystem, it’s a compelling choice. For most, however, the Ryobi’s slightly larger deck, bigger grass box, and the inclusion of a grass trimmer and battery in the kit provide a more complete and versatile package.

Our Final Verdict: Is The RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit Worth It?

After extensive testing and careful consideration of user feedback, our conclusion is clear: the **RYOBI 18V ONE+ Cordless Lawnmower and Grass Trimmer Twin Kit** is an outstanding package for the right user. Its greatest strengths are its incredibly lightweight design, ease of use, and the fantastic value of getting two capable garden tools that run on the same versatile battery platform. For homeowners with small to medium-sized lawns who are tired of the hassle of cords and petrol, this kit is a liberating and genuinely pleasant alternative.

Its primary weakness is not one of quality, but of capacity; the single 4.0Ah battery is the limiting factor. If your lawn is small (under 150m²) and you mow regularly, it will serve you beautifully. If your garden is larger, or you’re prone to letting the grass grow long, you must factor in the cost of a second battery for a frustration-free experience. If you understand that limitation, you’ll be rewarded with a quiet, efficient, and easy-to-store lawn care system that makes garden maintenance feel less like a chore. For its intended audience, we can wholeheartedly recommend it. Ready to cut the cord and experience true gardening freedom? Check the latest price and see its full feature set today.
