Bosch Rotak 43-750

Best Overall for Medium Lawns
4.6 / 5
Power750W
Cutting Width43cm
Grass Box50L
Weight13.5kg
Pros
  • Powerful 750W motor cuts through thick grass
  • Large 50L grass box reduces emptying stops
  • Leaf Collect function for autumn use
Cons
  • Cord limits range to power outlet
  • Heavier than some cordless models

The Bosch Rotak 43-750 is a corded electric mower designed for medium-sized lawns up to 500 square metres. Its 750W motor provides consistent cutting power, even in damp or overgrown grass. The 43cm cutting width strikes a good balance between speed and manoeuvrability, and the 50-litre grass box is one of the largest in its class, meaning fewer trips to the compost heap.

Owner reviews consistently praise the cut quality and the "Leaf Collect" feature, which uses a special blade to lift and collect leaves in autumn. The single-lever height adjustment offers seven settings from 20mm to 70mm. The main drawback is the power cord, which requires careful management to avoid cutting it. Overall, it is a reliable, high-performance mower for those with access to an outdoor socket.

Expert take: The Rotak 43-750 offers the best power-to-price ratio in Bosch's corded lineup. It is ideal for users who prioritise cut quality and large capacity over cordless convenience.

Bosch UniversalRotak 36-550

Best Cordless for Small to Medium Lawns
4.4 / 5
Voltage36V (2x18V)
Cutting Width36cm
Grass Box40L
Runtime55 min
Pros
  • Quiet cordless operation
  • Folding handles for easy storage
  • Good runtime for medium lawns
Cons
  • Batteries and charger sold separately
  • Not as powerful as corded models

The Bosch UniversalRotak 36-550 is a cordless mower that runs on two 18V batteries, providing 36V of power. It is designed for lawns up to 300 square metres and offers a runtime of up to 55 minutes on a full charge. The 36cm cutting width is narrower than corded models, but this makes it lighter and easier to push around flower beds and tight corners.

Users appreciate the quiet operation, which allows for early morning or evening mowing without disturbing neighbours. The grass box has a fill indicator, and the handles fold flat for compact storage. The main downside is that the batteries and charger are often sold separately, increasing the initial cost. For those already invested in Bosch's 18V system, this is a convenient addition.

Expert take: The UniversalRotak 36-550 is a well-balanced cordless mower that trades raw power for convenience and quietness. It is a strong choice for smaller gardens where a cord is impractical.

Bosch CityMower 18-32

Best for Small Gardens and Patios
4.3 / 5
Voltage18V
Cutting Width32cm
Grass Box31L
Weight11.5kg
Pros
  • Lightweight and easy to carry
  • Compact design for small lawns
  • Single 18V battery system
Cons
  • Small grass box fills quickly
  • Limited runtime on one battery

The Bosch CityMower 18-32 is purpose-built for small urban gardens, patios, and lawns up to 150 square metres. It runs on a single 18V battery, making it lighter and more affordable than the 36V models. The 32cm cutting width is narrow enough to navigate tight spaces, and the mower weighs just 11.5kg, making it easy to lift and store.

Owner feedback highlights the CityMower's ease of use and quiet operation. The 31-litre grass box is adequate for small lawns, but may need emptying mid-mow on taller grass. The single-lever height adjustment offers six settings. The main limitation is runtime; with one 2.5Ah battery, you get about 20-25 minutes of cutting, which is enough for a small lawn but not for larger areas.

Expert take: The CityMower 18-32 is an excellent entry-level cordless mower for those with a small garden. It is best suited to users who already own Bosch 18V tools and want a lightweight, compact mower.

Bosch Rotak 34-650

Best Corded for Small Lawns
4.5 / 5
Power650W
Cutting Width34cm
Grass Box40L
Weight11.5kg
Pros
  • Powerful for its size
  • Compact and easy to store
  • Good grass box capacity for small lawns
Cons
  • Cord can be restrictive
  • Not suitable for large lawns

The Bosch Rotak 34-650 is a smaller corded mower ideal for lawns up to 300 square metres. Its 650W motor provides ample power for regular cutting, and the 34cm cutting width allows for precise manoeuvring around obstacles. The 40-litre grass box is generous for the mower's size, reducing the frequency of emptying.

Owner reviews note the sturdy build quality and the effective grass collection, even in damp conditions. The single-lever height adjustment is easy to use, and the handles are comfortable. Like all corded mowers, the power cord requires careful routing, but the Rotak 34-650 is a reliable, no-fuss option for smaller gardens where battery life is a concern.

Expert take: The Rotak 34-650 is a compact powerhouse. It is a great choice for those who want the reliability of a corded mower without the bulk of a larger model.

Bosch AdvancedRotak 36-650

Best Cordless for Large Gardens
4.4 / 5
Voltage36V (2x18V)
Cutting Width46cm
Grass Box50L
Runtime65 min
Pros
  • Wide 46cm cutting width for large lawns
  • Long runtime with two 4.0Ah batteries
  • Large 50L grass box
Cons
  • Heavier than smaller cordless models
  • Batteries and charger sold separately

The Bosch AdvancedRotak 36-650 is the top-tier cordless mower in Bosch's range, designed for lawns up to 500 square metres. It uses two 18V batteries in series to deliver 36V of power, with a runtime of up to 65 minutes when using two 4.0Ah batteries. The 46cm cutting width is the widest in Bosch's cordless lineup, allowing you to cover more ground with each pass.

Owner reviews highlight the excellent cut quality and the large 50-litre grass box, which is comparable to corded models. The mower features a "ProSilent" motor for quiet operation, and the handles are ergonomic. The main drawback is the weight, at around 18kg with batteries, which can be tiring on hilly lawns. It is best suited to larger, flat gardens where cordless freedom is a priority.

Expert take: The AdvancedRotak 36-650 is Bosch's most capable cordless mower, offering near-corded performance. It is ideal for users with large lawns who want to avoid the hassle of a power cord.

What to check before buying a Bosch lawn mower

Before purchasing a Bosch lawn mower, consider your lawn size. For lawns under 200 square metres, a cordless model like the CityMower 18-32 or UniversalRotak 36-550 is ideal. For lawns between 200 and 500 square metres, the corded Rotak 43-750 or the cordless AdvancedRotak 36-650 are better suited. Also check the battery platform: if you already own Bosch 18V tools, a cordless mower that uses the same batteries will be more cost-effective.

Grass box capacity is another key factor. A larger box means fewer stops to empty, which is important for larger lawns. The Rotak 43-750 and AdvancedRotak 36-650 both offer 50-litre boxes, while smaller models have 31-40 litre boxes. Finally, consider storage space: cordless models with folding handles are easier to store in sheds or garages.

Mistakes to avoid when choosing a Bosch lawn mower

A common mistake is buying a cordless mower without checking the battery runtime. If your lawn is larger than 200 square metres, a single 18V battery may not be enough. Always check the runtime with the specific battery capacity you plan to use. Another mistake is overlooking the cutting width. A wider cut reduces mowing time but can be harder to manoeuvre around obstacles. Choose a width that matches your garden layout.

Finally, do not assume all Bosch mowers come with batteries and chargers. Many cordless models are sold as "body only," meaning you need to purchase batteries separately. Factor this into your budget. For corded models, ensure you have a suitable outdoor power outlet and a long enough extension cord.

Bosch lawn mower battery ecosystem

Bosch uses its 18V "Power for ALL" battery system for many of its cordless mowers, including the CityMower 18-32 and the UniversalRotak 36-550. This system is shared with other Bosch garden tools and DIY tools, allowing you to use the same batteries across multiple devices. The 36V mowers use two 18V batteries in series, which provides more power but requires two batteries to operate.

Battery capacities range from 2.0Ah to 6.0Ah. For mowing, a 4.0Ah or 5.0Ah battery is recommended for adequate runtime. The chargers are typically fast, charging a 4.0Ah battery in about 60 minutes. If you are starting from scratch, consider buying a kit that includes batteries and a charger to save money.

How Bosch mowers compare to competitors

Bosch mowers compete directly with models from Flymo, Stihl, and Einhell. Bosch generally offers better build quality and more consistent grass collection than Flymo, but Flymo models are often lighter and cheaper. Stihl mowers are more powerful and durable but come at a higher price point. Einhell offers good value for money, but Bosch has a more extensive battery ecosystem and better customer support.

For corded mowers, Bosch's Rotak series is among the best in terms of cut quality and grass box design. The "Leaf Collect" feature is unique to Bosch and adds significant value for autumn use. Overall, Bosch strikes a strong balance between performance, reliability, and price, making them a solid choice for most homeowners.
