Product description

Yard Force Amiro 400: the ideal caregiver for your lawn

Mulch system for a healthy lawn

The robot grass cutter Yard Force Amiro 400 cuts your lawn precisely with three sharp blades. In its continuous operation, the grass cuttings fall to the ground where they are decomposed, fertilising and moisturising your lawn. The result is clear: Your lawn is cut precisely, is healthy and emerald green.


Always up-to-date

A USB-interface enables an easy and fast solution for software updates. Furthermore, it allows an error diagnosis in only 30 seconds.


Yard Force Amiro 400: the ideal caregiver for your lawn

The Yard Force Amiro 400 is perfectly suitable for smaller gardens in cities or suburbs. It masters areas of up to 400 m2. Below its cover there is a powerful battery with 20 V / 2,0 Ah. With it, the robot grass cutter climbs slopes of up to ± 25 %. The cutting height can be adjusted between X and Y.



Takes a break when it starts raining

A rain sensor is mounted on the robot grass cutter by default. As a result, the robot returns to the charging station automatically as soon as it starts raining. The mowing task will be completed later, as soon as it has stopped raining.

Perfect for small gardens

This mowing robot is suitable for small gardens with a lawn area of up to 400 m2. It mows this area fully automatically, recognising the end of the area by the boundary wire and moving the lawn within the area in a random pattern.

Masters gradients of up to ± 25%

If there is an incline within the lawn, the robot can easily overcome it. This gradient must not exceed ± 25 %. It is important to note that the boundary wire cannot be laid on a slope.

For a safe operation


Equipped with lift and tilt sensors

The robot mower is equipped with lift and tilt sensors. This means that the blades stop immediately if the robot is lifted or tilted.


A radar sensor detects obstacles in time

The robot lawn mower detects obstacles in a distance of about 0,2 to 2 m with its radar sensor. Therefore, the robot mower navigates proactively, adjusting its direction skilfully as soon as an obstacle is recognised.

Yard Force Amiro 400 is installed easily

The robot mower Yard Force Amiro 400 convinces with its easy-to-use technology and simple installation. The robot is ready to go and start mowing your lawn in only a few movements.


Simple operation and programming

The robot grass cutter can be operated intuitively through a large control panel. With it, the robot is programmed and controlled easily.


The new Yard Force Amiro series

The new robot mower of the Yard Force Amiro series convinces not only with its design and functionalities but also with its low weight of only 7.4 kg. Because of that, it is very easy to transport and store (e.g. in winter).

Customer Review(s)

5-year guarantee5-year guarantee

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.


Is your device broken?

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.

  2. Please take care of packing the robot carefully to avoid damage.

  3. Enclose a detailed description of the fault as well as the invoice together with the 5-year guarantee certificate.

  4. The robot must be fully postage paid at and sent to the mentioned address.

  5. Transport costs are paid by you and will not be refunded. We recommend that you keep the postage receipt.
