Is This the Cheapest Robotic Mower Ever?

Today I’m taking a look at what could be the cheapest robotic mower available in the UK market – the Aldi Ferrex robotic mower, priced at just £199.99. I came across this mower recently and found it quite remarkable how low the price is compared to other models on the market. Incidentally, we do offer various types of robotic mowers, starting from around £357. As I mentioned, cheap doesn’t always work out cheap, I don’t want to undermine anyone’s machine, but it’s important that you have a parts backup and something that’s going to last few years.
Features of the Aldi Ferrex Robotic Mower
This mower is currently available through Aldi’s Special buy promotions. It covers lawns up to 400 square metres, which is ideal for many small to medium-sized UK gardens. The cutting heights are adjustable between 20 and 55 millimetres, and it comes equipped with:
- Obstacle sensors to avoid bumps
- Tilt sensors to stop the blades if lifted
- Turnover sensors for safety if it flips
It handles slopes up to 30% and is controlled via a Bluetooth app for scheduling mowing times. For a mower at this price point, these features are quite impressive. It also includes a charging station and an all-weather cover.
Perimeter Wire Setup
Unlike newer robotic mowers that use GPS or camera-based navigation, this Aldi mower requires a perimeter boundary wire to define the mowing area. The wire comes included, but it can take 1–2 hours to install properly, depending on your garden size and layout.
From my experience, it’s worth taking your time to set up the wire correctly, especially around edges, to avoid missing any areas and to reduce the need for trimming.
Is Cheapest Really Cheapest in the Long Run?
Although £199.99 is incredibly cheap for a robotic mower, it’s worth considering long-term running costs and availability of spare parts. Aldi’s mower is made by Ferrex, a German company, but it’s unclear how easy it will be to source parts if needed.
I generally prefer investing in quality machinery. Even though you’re not physically pushing a robotic mower, it’s still important to have something reliable and well-constructed that will last for many seasons.

Robotic Mower vs Contractor Costs
I often remind people that while a robotic mower is an upfront investment, it can save significant costs over time. For example, if you pay a contractor £600 per year to cut your grass, over 5 years that totals £3,000. In comparison, a one-off robotic mower purchase of around £500 plus minimal running costs can represent excellent long-term value.
Final Thoughts
Personally, I like to invest in quality machinery that’s built to last. Whether you choose an Aldi Ferrex mower or a higher-end Husqvarna or Gardena model, robotic mowers are a great way to save time and maintain your lawn effortlessly.
