Product description

Yard Force SA800PRO: Ideal for large and hilly properties

Innovative Multi-Zone-programming

The Yard Force SA800PRO is equipped with the so-called multi-zone-programming. For this reason, the robot grass cutter can also be operated on more complex lawns or ancillary areas.


Numerous sensors for a safe operation

When touching an obstacle or another barrier, the robot mower turns around and continues mowing in another direction. It is the same with slopes: If the slope is too steep, the robot changes its direction.

With a PIN code the robot lawn mower is protected against usage of unauthorised people or children or theft.

Lift and tilt sensors: If the robot grass cutter is lifted or tilted, its blades stop immediately. Maximum safety near children and animals is assured.

An integrated rain sensor enables the recognition of rainfall. If this is the case, the robot mower returns to its charging station. The mowing task will be continued as soon as the weather is better.

Masters slopes of up to ± 50 %

The robot lawn mower SA800PRO is equipped with a powerful Li-ion battery of 28 V / 2,9 Ah for maximum mowing power. Uneven properties with slopes of up to ± 50 % (or 27°) can be mowed effortlessly. With the multi-zone-programming, the robot grass cutter can also handle ancillary areas.

Equipped with a built-in rain sensor

The built-in rain sensorautomatically detects the Yard Force SA800PRO robot mowerwhen it starts raining. The robot lawn mower will automatically return to its charging base and resume mowing only when the weather is dry. If desired, the rain sensor can be deactivated.

Suitable for complex surfaces

Thanks to its innovative multi-zone programming and sensor technology, the Yard Force SA800PRO robot lawn mowercan also be used for complex or hilly gardens. It is the right choice for larger lawns up to 800 m². The cut surface of 18 cmallows quick and effective garden maintenance.

Particularly easy to use

Clear control panel for an easy programming

Many settings can be edited individually on the illuminated touch-screen display (control panel). The menu is modern and very easy to use. On the control panel there can be selected the following settings: start mowing, start charging as well as general settings such as a timer and the correct language and date.


 Accessories are included

All accessory parts that are needed for the initial installation are included in the scope of delivery. Therefore, an easy and fast installation is guaranteed.

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.
