Product description

The robot lawn mower for the small garden: Gardena Sileno City

This robotic lawn mower is specially designed for small lawns up to 250 m2. It is an ideal additional robot for small, separate ancillary areas. It is equipped with a robust Lithium ion battery and manages gradients of up to ±25 % (14°). The volume while working is only about 60 dB which equals the volume of a normal conversation.


Small robot mower, great performance – even on complex terrain

Despite the low area coverage, you can set up to three starting points for your robotic lawn mower. Thus, it is also suitable for the usage on a complex property with several ancillary areas because it finds its way in remote areas of the garden which are connected to the main area only through narrow corridors. This ensures an optimum mowing result all-over.


Intelligent navigation through narrow passages

The Gardena Sileno City robot lawn mower is equipped with the feature “Easy Passage” and therefore is able to navigate efficiently and quickly through narrow corridors.


Gardena Sileno City mows your lawn fully automatically

Mowing schedule

With the user-friendly LCD display with keypad you can set up a weekly schedule for your robotic lawn mower. It follows the schedule even when it is raining. After work or when battery is low, the automatic lawn mower returns to the charging station to recharge.


Mulching function for a healthy lawn

Three blades which are mounted on a rotating disc cut the lawn reliably while the robot mower crosses the garden at random. The cutting height can be individually adjusted between 0.8 and 2 in. The fine grass cuttings fall down to the ground where they are slowly decomposed and serve the lawn as a natural fertilizer and moisturizer.


Sensors assure a safe operation

The Gardena Sileno City 250 is equipped with collision, lift and tilt sensors for maximum safety. If the robot hits an obstacle it stops and navigates into another direction. If lifted or tilted, the robot lawn mower’s blades stop immediately. A PIN code protects it against theft or unauthorized usage.


Easy maintenance and installation

After just a few steps, the robot lawn mower is ready for operation. All accessories needed for the installation, like perimeter wire, pegs, cable connectors and the user’s manual, are included in the scope of delivery.


The Gardena Sileno City only weighs 15.4 lb and is therefore very handy. According to the manufacturer, this model can be cleaned with the garden hose and under running water.

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.
