Flymo EasiLife 100
Best OverallPros
- Reliable boundary wire guidance
- Good battery runtime for small lawns
- Easy to install and program
Cons
- Requires boundary wire installation
- Not suitable for complex lawn shapes
The Flymo EasiLife 100 is a solid entry-level robot mower that uses a boundary wire to stay within your lawn. Owner reviews consistently mention its reliable navigation and simple setup, making it a great choice for first-time buyers. The 2.0 Ah battery provides enough runtime to cover a 300 sqm lawn in a single charge cycle.
Build quality is decent for the price, though the plastic chassis feels light. It handles flat, open lawns well but struggles with steep slopes or narrow passages. For a straightforward, no-fuss mower under £100, this is the most dependable option available.
Worx Landroid L WR100
Best Wire-FreePros
- No boundary wire needed
- Very easy to set up
- Lightweight and portable
Cons
- Random navigation may miss spots
- Smaller area capacity
The Worx Landroid L WR100 is a true wire-free robot mower, using a random bouncing pattern to cover your lawn. This makes setup incredibly simple, as you just place it on the grass and let it go. Owner reviews highlight its convenience for very small, simple lawns, but note it can sometimes miss patches or get stuck on uneven ground.
Battery life is adequate for a 200 sqm area, but the random navigation means it might take longer to achieve an even cut. It is best for those who want a hassle-free, no-installation solution and have a small, flat lawn without obstacles.
Bosch Indego S 350
Best for Small LawnsPros
- Efficient Logicut navigation
- Larger battery capacity
- Strong brand reliability
Cons
- Price may exceed £100 at times
- Requires boundary wire setup
The Bosch Indego S 350 uses Logicut technology to mow in logical rows rather than random patterns, resulting in a more even cut. Owner reviews praise its efficiency and the quality of the cut, especially on smaller lawns. The 2.5 Ah battery gives it a bit more runtime than the Flymo.
This model often sits just above the £100 mark, but can occasionally be found on sale within budget. Build quality is excellent, typical of Bosch, and it handles slopes better than most budget models. If you can stretch your budget or find a deal, this is a top performer.
Einhell GC-RM 500
Best for Larger AreasPros
- Largest area capacity in class
- Good cutting width
- Decent build for the price
Cons
- Can be noisy
- Setup instructions could be clearer
The Einhell GC-RM 500 is designed for larger lawns, offering a 500 sqm capacity that outpaces most competitors at this price point. Owner reviews note it handles medium-sized gardens well, with a 2.5 Ah battery that provides longer runtimes. The 19 cm cutting width also helps cover ground faster.
Some users report that the mower can be a bit noisy during operation, and the initial setup of the boundary wire requires patience. However, for the price, it offers excellent value for those with a bigger lawn who want to stay under £100.
Flymo EasiLife 150
Best Value UpgradePros
- Larger area capacity than EasiLife 100
- Same reliable Flymo system
- Good value for the upgrade
Cons
- Same battery as smaller model
- Not much difference in features
The Flymo EasiLife 150 is a step up from the 100 model, offering a 400 sqm area capacity while maintaining the same reliable boundary wire navigation. Owner reviews appreciate the extra coverage for slightly larger lawns, and the build quality remains consistent with the Flymo brand. It is a straightforward upgrade if you need more range.
The main downside is that it uses the same 2.0 Ah battery as the smaller model, so runtime is not significantly improved. However, for the price, it is a solid option for those who want a bit more lawn coverage without moving to a more expensive brand.
What to check before buying a robot mower under £100
Before you buy, measure your lawn area accurately. Most budget mowers cover between 200 and 500 sqm. Check the slope rating too, as many cheap models cannot handle gradients over 20 percent. Also, consider whether you are willing to install a boundary wire, as wire-free models are simpler but less efficient.
Mistakes to avoid
A common mistake is buying a mower with too small a battery for your lawn size. Another is ignoring the need for a boundary wire, which can be time-consuming to install. Finally, do not expect premium features like app control or GPS at this price point.
FAQs
