Makita DLM431Z
Best OverallPros
- Strong 36V motor cuts thick grass easily
- Robust build quality with steel deck
- Large 50L grass box reduces emptying frequency
Cons
- Heavier than some rivals at 16.5 kg
- Batteries sold separately
The Makita DLM431Z uses two 18V batteries in series to deliver consistent 36V power, making it ideal for small gardens with tougher grass. Owner reviews on Amazon highlight its reliable cutting performance and the durable steel deck that withstands regular use. The 43 cm cutting width is generous for a small lawn, allowing you to finish mowing in fewer passes.
However, the weight of 16.5 kg can be noticeable when pushing on slopes, and the lack of included batteries means an additional investment if you are not already in the Makita ecosystem. For those who prioritise build quality and power over portability, this is a strong choice.
Bosch Rotak 32
Best LightweightPros
- Very lightweight at 10.5 kg
- Compact design for easy storage
- Bosch 18V battery system is widely available
Cons
- Small 31L grass box fills quickly
- Less powerful on thick, wet grass
The Bosch Rotak 32 is designed for manoeuvrability, weighing just 10.5 kg and featuring a 32 cm cutting width that fits neatly into tight spaces. Aggregated owner reviews praise its ease of use, especially for those who find heavier mowers tiring. The 18V battery system is shared across many Bosch garden tools, making it a good entry point for a broader ecosystem.
On the downside, the smaller grass box requires frequent emptying on lawns over 150 square metres, and the motor can struggle with longer or damp grass. For regular, light mowing on a small, well-maintained lawn, it is an excellent choice.
Flymo EasiStore 340
Best BudgetPros
- Vertical storage saves shed space
- Good 40L grass box capacity
- Affordable price point
Cons
- Plastic deck feels less durable
- Battery runtime is average
The Flymo EasiStore 340 is a budget-friendly option that does not compromise on essential features. Its 40V battery provides enough power for small lawns, and the 34 cm cutting width is suitable for most gardens. The standout feature is the vertical storage design, which allows the mower to stand on its end, taking up minimal floor space in a shed or garage.
Owner reviews note that the plastic deck is lighter than steel alternatives but may not last as long under heavy use. The battery runtime is sufficient for a single mow of a small lawn, but you may need a spare for larger areas. For the price, it offers excellent value.
Ryobi RLM36X45S
Best EcosystemPros
- Large 55L grass box for fewer stops
- Ryobi ONE+ system shares batteries with 100+ tools
- Brushless motor for efficiency
Cons
- Heavier than many small garden mowers
- Batteries and charger sold separately
The Ryobi RLM36X45S is part of the Ryobi ONE+ system, meaning the same 36V battery can power a range of garden and DIY tools. This makes it a smart choice if you already own Ryobi equipment or plan to expand your toolkit. The brushless motor provides good efficiency, and the 55-litre grass box is one of the largest in this category, reducing trips to the compost heap.
At 17.0 kg, it is on the heavier side, which may be a concern for smaller gardens with uneven terrain. Owner reviews consistently mention the excellent build quality and the convenience of the shared battery platform. For those invested in the Ryobi ecosystem, this mower is a natural fit.
Stihl RMA 235
Best CompactPros
- Very compact and easy to store
- Lightweight at 11.0 kg
- Stihl brand reliability
Cons
- Small 30L grass box
- Limited availability of spare batteries
The Stihl RMA 235 is designed for tight spaces, with a 32 cm cutting width and a weight of just 11.0 kg. It is one of the most compact cordless mowers available, making it easy to manoeuvre around flower beds and narrow paths. Stihl is known for its professional-grade outdoor equipment, and this mower benefits from that reputation for durability.
Owner reviews note that the grass box is small, requiring frequent emptying even on modest lawns. The battery system is specific to Stihl, which limits cross-compatibility with other brands. For those who value a compact, reliable mower from a trusted brand, the RMA 235 is a solid choice.
What to check before buying a cordless lawn mower for a small garden
Cutting width is the most important factor for a small garden. A width between 30 cm and 45 cm allows you to navigate tight spaces while still covering the lawn efficiently. Battery voltage, typically 18 V to 40 V, determines power; for small gardens, 18 V is often sufficient, but 36 V models handle thicker grass better.
Weight matters because you will lift the mower for storage and push it on slopes. Look for models under 15 kg if you have limited strength or uneven terrain. Grass box capacity should be at least 30 litres to avoid constant emptying. Finally, check the battery ecosystem: if you already own tools from a brand like Makita or Ryobi, sticking with that brand saves money on spare batteries.
Mistakes to avoid when choosing a cordless mower
Do not buy a mower with a cutting width larger than your garden requires. A 45 cm mower may be faster on a 300 sq m lawn, but it will struggle to trim edges and fit through narrow gates. Also, avoid models with non-removable batteries, as they limit runtime and make replacements expensive.
Another common mistake is ignoring the grass box design. Some mowers have rear-mounted boxes that make it difficult to mow close to walls. Side-discharge or mulching options are worth considering if you want to leave clippings on the lawn. Finally, do not assume all cordless mowers are quiet; check decibel ratings if noise is a concern for neighbours.
