Product description

A useful robot mower for smaller gardens – with app-control


A robot mower for smaller gardens

The Yard Force Amiro 400i is especially suitable for smaller gardens in cities or suburbs with a maximum surface of 400 m2. The in-built Li-ion battery of 20 V / 2 Ah provides the needed energy to carry out the mowing tasks reliably. Furthermore, the robot lawn mower climbs slopes of up to ±25 %.


A healthy lawn thanks to the mulch function

The Yard Force Amiro 400 i is equipped with a disc of three blades. The grass is cut with a cutting width of 16 cm. The robot mower drives through your garden in a random pattern, cutting only little of the grass. The fine grass cuttings fall to the ground as mulch where they serve as a natural fertiliser. That hydrates the lawn so that it becomes healthy and lush green.

 Smart rain sensor

Thanks to the in-built rain sensor, the robot mower Yard Force Amiro 400i detects rain. In this case, it returns to its charging station and charges itself, waiting for it to stop raining. As soon as the weather is better, it continues mowing.

Perfect for small suburban gardens

We recommend the lawn mower robot for gardens with a lawn area of up to 400 m2. A boundary wire is laid to allow the robot to detect the end of the lawn.

Overcomes gradients of up to ± 25%

The Yard Force Amiro can travel on small hills within its working area if these do not exceed a gradient of ± 25 %. Important: The gradient must not be along the boundary wire.

Comfortable control via smartphone-app

The Amiro 400i by Yard Force can be controlled and programmed via smartphone-app easily. Furthermore, important information and notifications about the robot grass cutter are communicated via app. The app is available for iOS and Android and can be used in 13 languages.


Useful USB interface for software-updates

The robot grass cutter has an in-built USB interface. With it, you can carry out software updates very easily. Furthermore, it enables a fast error diagnosis in only 30 seconds.

  Numerous sensors for a safe operation

Lift and tilt sensors stop the blades

The robot lawn mower is provided with lift and tilt sensors. Therefore, the blades of the robot stop immediately, if it is lifted or tilted.


Recognises obstacles with a radar sensor

The ultra-sonic sensor (radar sensor) enables the detection of obstacles in a distance of about 20 cm. If this is the case, the robot mower is able to adjust its way because its reaction time is only two milliseconds. Thanks to the radar sensor, the robot grass cutter carries out its mowing task proactively.

Easy installation and operation

The robot mower convinces with a user-friendly technology and a large control panel. It is ready-to-use in only a few steps.

Customer Review(s)

With their technical sophistication and excellent range of features, robots from myRobotcenter never fail to impress. Our robots are guaranteed to provide you with more free time and a better quality of life. Guarantee is also the key word when it comes the longevity of our products. Thanks to their sophisticated, tried and tested technology, our products have proven to be extremely reliable and free of faults. If a design fault should arise, then you can rely on a guarantee that – with many products – extends far beyond the statutory minimum.


Extension of the guarantee to 5 years

Our products come with a manufacturer's guarantee (generally 2 years). At myRobotcenter you get an even longer guarantee on many products: we extend the guarantee period to 5 years.


Complete security over many years

Our 5-year guarantee on labelled products is both a mark of quality and a very special service for you as our customer. In addition to the respective guarantee, we provide  you with all the details about the conditions of our guarantees and which services you can expect from us.


What does the guarantee cover?

The 5-year guarantee covers devices bought from us when accompanied by a receipt or another document that proves the validity of the 5-year guarantee. The 5-year guarantee ends five years after the device was purchased. The guarantee is valid for guarantee claims that occur in United Kingdom.


A guarantee claim is valid when the device purchased by you is damaged or destroyed, as a result of the following causes:

  • construction fault, calculation error, casting defect, material defect and production fault

  • direct effects of electrical energy as a result of a ground fault, short circuit, excessive increase in the current strength, electrical arc-over, formation of electrical arcs, insulation faults, excess voltage and the like.

Excluded from the guarantee is damage caused by external influences, such as a bounce flash in the circuit or fire damage. Such externally induced damages can be covered under certain circumstances by your household insurance and may include:

  • measuring, controlling and safety device failures

  • excessive pressure other than explosions

  • implosion and other effects of insufficient pressure

  • lack of water in steam boiler and other apparatus

  • bursts due to centrifugal force


Within the framework of the extended guarantee, operating errors are covered insofar as they impair the functionality of the product and do not represent a contravention of the operating instructions. For such cases we shall charge an excess of 84 GBP including VAT.


What is NOT covered by the guarantee?

  • Wear and tear, and damage to wearing parts and batteries (the battery is only covered by the manufacturer's guarantee)

  • Damage that does not impair the technical function of the device, e.g. scratches and scuffs.

  • Damage or destruction due to intentional or grossly negligent acts or omissions on the part of the purchaser or other users of the device.

  • Damage or destruction caused by improper installation/assembly, by improper repairs/adjustments, by improper, non-intended or unusual use or cleaning of the device – especially when the manufacturer’s instructions are not followed – and by operating errors.


What service do we provide in valid guarantee cases?

  1. When repair is technically and objectively possible and the costs of repair do not exceed the current value of the device (see clause 3), the device shall be repaired professionally and the costs incurred in the repair reimbursed by the guarantee.

  2. Should repair be technically or objectively impossible or uneconomical (total write-off), you shall receive a replacement device of the same kind and quality up to the amount of the current value (see clause 3). The damaged or destroyed device is returned to us and becomes our property.

  3. The current value of your device is 50% of the purchase price in the 3rd year after conclusion of purchase contract, 40% in the 4th year and 30% in the 5th year of the purchase price as stated in the receipt.

Just ask us for help. We will support you with the repair request.

  1. In the matters of a needed repair, a skilled and trained team in service and repair department from us or from the manufacturer itself, will gladly be there for you with advice and act to the side.
