Flymo MicroBot M20
Best OverallPros
- Quiet operation at 57 dB
- Simple boundary wire installation
- Good owner reviews for reliability
Cons
- Not suitable for slopes over 25%
- No app control
The Flymo MicroBot M20 is a solid entry-level robotic mower designed for small, simple lawns up to 200 m². It uses a boundary wire to define the cutting area and returns to its charging station automatically when the battery is low. Owner reviews highlight its quiet motor and consistent cutting pattern, making it a reliable choice for keeping a small garden tidy without manual effort.
Setup is straightforward, though the boundary wire must be pegged down carefully. The mower handles flat terrain well, but it struggles on steep slopes. For the price, it offers dependable performance and a good warranty from a trusted brand.
Einhell City Mower GC-RM 500
Best for Very Small LawnsPros
- Very quiet at 55 dB
- Compact and lightweight
- Easy to install and program
Cons
- Limited to very small lawns
- No rain sensor
The Einhell City Mower GC-RM 500 is purpose-built for tiny gardens and courtyards. Its small footprint and low noise level make it ideal for urban settings where neighbours are close. The mower follows a random pattern and returns to its base when the battery runs low. Owner feedback praises its simplicity and the fact it rarely gets stuck on flat ground.
Battery life is sufficient for a single mowing session on a 150 m² lawn. The lack of a rain sensor means it will continue cutting in wet conditions, which can lead to clumping on damp grass. For the price, it is a capable little machine for the smallest lawns.
Bosch Indego S 300
Best Smart FeaturesPros
- App control and scheduling
- LogiCut mapping for efficient mowing
- Rain sensor included
Cons
- Boundary wire installation required
- Can struggle with narrow passages
The Bosch Indego S 300 brings smart features to the budget segment. Its LogiCut system maps the lawn and mows in logical strips rather than random patterns, which saves battery and time. The accompanying app allows you to set schedules, adjust cutting height, and monitor status from your phone. Owner reviews rate the app highly for its ease of use.
It covers up to 300 m², making it one of the larger capacity mowers in this price bracket. The rain sensor is a useful addition that prevents it from cutting in wet weather. Some users report it can get confused in gardens with very narrow paths, but for most medium-sized lawns it performs well.
Flymo MicroBot M100
Best for Compact SpacesPros
- Smallest footprint in range
- Low cost
- Easy to store
Cons
- Very limited lawn area
- No scheduling timer
The Flymo MicroBot M100 is the most compact and affordable robotic mower from a major brand. It is designed exclusively for very small lawns, patios with grass strips, or tiny gardens. Its small size means it can navigate tight corners and narrow borders that larger mowers cannot. Owner reviews note it is very easy to set up and requires minimal maintenance.
Battery life is limited, which is why the maximum area is 100 m². It lacks a programmable timer, so it mows on demand or when manually started. For the smallest of spaces, it is a no-fuss solution that gets the job done at the lowest entry price.
Worx Landroid M WR130E
Best for Larger Budget LawnsPros
- Largest area coverage in class
- Adjustable cutting height
- Works with Worx battery platform
Cons
- Heavier unit
- Can be noisy compared to others
The Worx Landroid M WR130E stands out for its ability to handle lawns up to 500 m², which is significantly more than any other mower in this price range. It uses a boundary wire and offers adjustable cutting height from 20 mm to 60 mm. The mower runs on Worx's 20 V battery platform, so batteries can be shared with other Worx tools. Owner reviews appreciate its robust build and consistent cutting on medium-sized lawns.
It is heavier than the competition, which can make it harder to move manually. The noise level is also higher, though still acceptable for residential use. For those with a larger lawn who cannot stretch their budget, the Worx Landroid M offers the best coverage per pound.
What to check before buying a robotic mower under £150
Lawn size is the most critical factor. Every mower has a maximum area rating, and exceeding it will result in incomplete cuts or dead batteries. Measure your lawn accurately before choosing a model.
Boundary wire installation is required for all mowers in this price range. You must peg the wire around the perimeter of your lawn. This takes time but is essential for the mower to know its limits.
Check the slope rating. Most budget mowers handle slopes up to 25% or 15 degrees. If your garden is hilly, look for a model with a higher slope tolerance or be prepared to manually mow steep sections.
Consider the cutting height adjustment. Some models offer multiple settings, while others have a fixed height. Adjustable height gives you more control over the finish of your lawn.
Think about noise. Budget mowers range from 55 dB to 65 dB. Quieter models are better for early morning or evening mowing in residential areas.
Mistakes to avoid when buying a cheap robotic mower
Do not ignore the boundary wire setup. Many owners underestimate the time required to lay the wire. Plan for at least an hour for a small lawn and longer for complex shapes.
Do not buy a mower rated for exactly your lawn size. Always choose a model with a slightly higher area rating to allow for battery degradation over time and to ensure the mower can finish in one session.
Do not skip checking the warranty. Budget mowers typically have a 2-year warranty. Register your product immediately after purchase to ensure coverage.
Do not assume all mowers handle wet grass. Models without a rain sensor will cut in the rain, which can damage the lawn and cause clumping. If you live in a rainy area, prioritise a mower with a rain sensor.
Do not forget about replacement parts. Blades and batteries wear out. Check that spares are readily available for the brand you choose. Flymo and Bosch have the best parts availability in the UK.
