Sensors for a safe use

The Yard Force SA900 ECO is equipped with a variety of safety sensors. It has lift, tilt and obstacle sensors. When the robot lawn mower is lifted or tilted, its blades stop within 2 seconds.

Mowing made easyMowing made easy

Mowing made easy

Here you can make certain settings for the Yardforce SA900ECO. Once the robot has been installed and programmed, it works independently and reliably.

Yard Force SA 900 ECO works independently

The Yard Force robot grass cutter is particularly easy to operate. Once the robot lawn mower has been installed, it works independently. This also applies to its loading process. If its battery becomes low, it drives into its charging station, recharges itself and then mows again.  


Robot for terrain with slopes

Its compact design and the built-in Li-ion battery (28 V / 2.9 Ah) enable the robot lawn mower to mow uneven as well as steeper areas. The cutting height of the Yard Force SA900 ECO is adjustable. 5 steps between 20 and 60 mm are available. This means that the cutting height can be ideally selected for spring and summer period.


Automatic mowing and loading process

The property to be mown must be marked out with a circumferential boundary wire. Settings for the Yard Force SA900ECO can be made from the control panel. The Yard Force 900ECO is by default programmed to operate seven days a week.

Once the mowing time has been determined, the mowing robot works reliably and starts its mowing job daily, at the same time. If its battery becomes weak during mowing, the Yard Force SA 900 ECO visits its charging station. It charges itself automatically and goes on with its mowing process till the mowing program has been finished.


Naturally fertilizes your lawn

The robot grass cutter works with a mulching system. The grass is always shortened a little during the daily work. The fine lawn particles fall to the ground, decompose and serve the lawn as a natural fertilizer and moisturizer.


Mows (not) when it rains

A built-in rain sensor detects precipitation and causes the Yard Force SA900 ECO to interrupt the mowing process. When it rains, it drives into its charging station and waits for better weather. The built-in rain sensor can be switched on or off.

Note: The Yard Force SA900ECO can also mow wet grass. However, this can stick to the blades, the blade disc and the wheels. This can lead to an increased need for maintenance and cleaning. The blades must always be in good condition for a good cutting pattern and good mowing performance!

Maximum safety and easy operation

A safe mowing operation is ensured

The Yard Force 900ECO robot lawn mower is protected with a PIN code and is therefore also protected against theft. If the robot is stolen from your garden, it cannot be started without the security pin.


Built-in tilt, lift and obstacle sensors

Equipped with an effective safety lock, the robot mower reacts immediately with a blade stop when it is raised or tilted. If the robot grass cutter drives against an obstacle, it stops, drives back and moves in another direction

Easy operation and installationEasy operation and installation

Easy operation and installation

All important accessory components for installation are included in the scope of delivery. The operation, as well as the programming of the robot lawn mower, is carried out via the screen. Once the appropriate program has been selected, the Yardforce SA 900 ECO works completely independently in your garden.

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.


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.
