Emission-free and quiet: 57 dB(A)

The Husqvarna Automower 420 offers all the advantages of Husqvarna's innovative mowing system and mows the lawn quietly (measured value: 57 dB) and emission-free. As the robot lawn mower is electrically powered, there are no harmful exhaust fumes. The particularly quiet transmission of the robot would also allow a use at night. Please pay attention to nocturnally active animals that might be on the move. 

Weather-timer & innovative technologyWeather-timer & innovative technology

Weather-timer & innovative technology

The weather timer makes it possible for the Automower 420 to automatically adjust its working intervals to the weather and grass growth. This allows the robot mower to increase its working time on wet and rainy days and reduce it on sunny or dry days. The robust blades do not cut much at once, but thanks to its daily trips they cut regularly and thus ensure a healthy lawn.

Automower Connect@HomeAutomower Connect@Home

Automower Connect@Home

Thanks to the standard Connect@Home module, the Husqvarna 420 robot lawn mower can be controlled using a smartphone via a Bluetooth connection. To use this feature, you and the robot must be in close proximity.

For the complete use of the app functions, such as on-the-go control, theft alarm and GPS-based navigation, the optional Automower Connect module must be retrofitted (see customer options).

The innovative cutting system from Automower 420

The robot grass cutter does not cut off much of the blades of grass every time but mows regularly. This guarantees a nice and healthy lawn. It is equipped with three razor-sharp blades that are mounted on a cutting disc. This ensures an efficient mowing process and at the same time low energy consumption.

Thanks to the innovative mowing system and a noise level of just 58 dB the robot lawn mower works very quietly and particularly energy efficient in ECO mode. The cutting height of the robot mowercan be adjusted electrically to the desired value between 20 and 60 mm.


Timer for an automatic mowing operation

The Husqvarna Automower 42 can be operated, controlled and programmed via a large, high-resolution display. If a timetable has been set for the robot lawn mower, it follows the schedule completely independently.

When the battery level is low, or after it has completed its mowing task, the robot grass cutter returns to its charging station to recharge. To locate the charging station, the robot mower can choose from four different navigation options.


Automatic passage detection

The Husqvarna Automower 420 is equipped with an automatic passage recognition, enabling it to detect narrow passages. It then adjusts its navigation accordingly to the prevailing conditions and passes through narrow corridors skilfully and efficiently. This means that hard-to-reach areas in the garden are no problem for the Automower 420.


Husqvarna Automower 420 offers a remote start function

It is possible to define up to five different starting points for the robot mower. This allows the robot lawn mower to reach even remote areas in your garden. This function ensures consistent, uniform processing of all surfaces (including ancillary areas), and thus an even lawn appearance.


Weather timer for an optimized mowing frequency

The weather timer of the Husqvarna 420 allows an optimized mowing frequency, which is adapted to grass growth in the garden. This means that the robot mower reduces its operation during dry periods and increases it when it rains. The lawn thus receives exactly the care it needs.


Obstacle, lift and tilt sensors ensure safety

Equipped with different sensors, the robot lawn mower reacts accordingly to changes. The built-in obstacle, lifting and inclination sensors ensure safe operation of the robot mower. The PIN code and alarm feature protect Husqvarna Automower against theft and make it childproof.


Colourful case cover

The cover of the robot grass cutter Husqvarna 420 can be removed and replaced with a different colour.

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.
