Automatic charging

When Automower® needs more power, it simply returns itself back to its docking/charging station and reenergises itself. Once fully charged and ready to go, it will simply return itself back to work until its scheduled cutting cycle is complete.


Automower® is designed to work you and your lifestyle. You decide when you want it to mow and when you do not, and if you change your mind, it is quick, simple and easy to change your programmed schedule.


Automower® is designed to be used outside, unattended and around the clock, regardless of the weather conditions, even the wet. In the winter months and extreme temperatures it would be advised to keep your mower inside a garage or shed, whether its compact size and weight allows it to be easily and conveniently stored or even hung.

Automower® Connect

Allows you to remotely operate Automower anytime from anywhere via your smart device. You can easily send start, stop, park commands and even change your desired cutting height of grass, as well and adjust other personal settings of your choosing to suit you

Weather timer

This ingenious function adjusts the working time of Automower® to suit the lawn’s rate of growth, thereby optimising mowing time during periods of increased grass growth. In sunnier and drier weather or late in the season, Automower® will spend less time mowing and in doing so, decrease lawn and mower wear.

Systematic passage mowing

In order to deliver excellent cutting results across the entirety of the lawn, Automower® can be set to automatically switch mowing pattern from random mode to systematic mode which senses and navigates the mower through narrow spaces, such as between flower beds etc, varying the route to avoid unpleasant track marks.

Frost guard

This function automatically interrupts the mowing schedule in frosty conditions for the betterment of the lawn.

Hose washable

Keeping your Automower® clean and presentable could not be easier. The exterior and underside of your Automower® can be quickly and conveniently washed down with a garden hose.

Anti-theft alarm with GPS tracking

Each Automower® has a unique PIN code for added protection and security. Settings can only be changed and the audible alarm deactivated using its unique PIN. The integrated Automower® Connect tracks GPS mower position and sends notifications to your connected devices, reducing the risk of theft.

Lift & tilt sensors

If Automower® is lifted off the ground or tips over, the cutting action of the mower automatically shuts off and stops. The rotating Automower® blades are also purposely positioned to sit within the underside and shielded part of the mower and far from the outer edge of the mower body for additional safety. If Automower® meets an obstacle whilst mowing the lawn, like a garden pot or ornament for example, it will simply and gently stop, redirect itself and travel in a different direction.

Remote start points x 5

This functions allows mowing in five different locations along the patented guide wire installed, say the front and rear garden of a property with no connecting lawn between the two for the mower to travel on. The mower can simply be manually carried from one location to the other and put to work. It will need to be manually returned to the docking station to recharge or when it has finished cutting the supplementary areas.

Front sensor

A sensor mounted to the front of the mower detects in advance upcoming obstacles in its intended direction of travel and takes preventive measures to avoid collision.

Spot cutting

Special mode to quickly mow a limited area of longer grass. This feature is especially useful for areas beneath for example garden furniture, play equipment etc, once the obstruction(s) have been removed allowing free and unobstructed movement of the mower. Simply place the mower in the desired area and choose the Spot cutting mode. The mower will then mow in tight spirals and when finished resume in automatic mode.

Spiral cutting

Automatic cutting function which determines a variation in grass height and mows the area in a spiral motion until the grass is cut and reduced to a uniform length.

GP assisted navigation - PATENTED

An on-board GPS system creates a map of the garden, including where the boundary and guide wires are installed, which the mower will then register which parts of the garden it has covered, adjusting its mowing pattern accordingly to ensure the full defined lawn area(s) specified are uniformly cut. This ensures optimised lawn coverage and an excellent cutting result.

LED headlights

Energy efficient and controllable LED headlights provide better visibility and control even in the dark. The lights will also start to flash if a malfunction occurs.

Electric cutting height - PATENTED

Allows cutting height to be easily and simply adjusted by the electrically operated height adjustment which can either be accessed via the main menu on the dashboard or remotely via smart device.

Zone control

Let’s you create defined work areas with different grass cutting heights and schedules, or stay out/exclusion zones off are off limit to the mower, for instance where an area has been reseeded etc, or areas where the grass is allowed to grow wild.

Husqvarna AIM Technology (Automower® Intelligent Mapping)

Husqvarna AIM technology uses on-board Automower® GPS and sensors to create a virtual map of the lawn as well as enabling a whole range of smart features. The virtual map created is then visible in the Automower® Connect app as well as the boundary and guide wires. With AIM technology you can use the app for personalised zone control as well as tracking mower


For improved lawn quality, TargetHeight lowers the cutting height automatically from MAX to defined height gradually and incrementally over a 10 day period.

FOTA – Firmware-Over-The-Air

This function permits the possibility to make software updates automatically over the air through Automower® Connect.

Backlit graphic display menu control

Backlit dashboard mounted high resolution, medium-sized display control panel with graphic menu structure. Easy to use with self-explaining set up.

Quiet in operation/Environmentally friendly

Thanks to the combination of its li-ion battery power and unique cutting system, Automower® is very quiet and discreet in operation reducing noise-pollution. Your neighbours often will not even be aware that Automower® is at work; day, night, early or late. Automower® is also environmentally friendly as it produces no CO2 emissions and consumes extremely low levels of energy.

Manages slopes up to 40%/22°

Thanks to the compact size, lightweight, chassis design and large coarse-tread drive wheels for optimised traction and balance even on slippery surfaces, the 305 has the ability to work on slopes up to 40%/22° and on undulating, uneven ground too.
