From the product description
The Automower 260 ACX is designed for semi-professional use in business or public environments as well as for demanding consumers. Like all Husqvarna's robotic mowers, it charges and operates itself without need for supervision. Should anything disturb the operation, 260 ACX sends a text message to your mobile phone. Thanks to 6000 sq. meter (1.4 acre) capacity, low noise level and no requirement of labour, Automower 260 ACX is perfectly suited for use in quiet environments such as hospitals, hotels and leisure facilities, and office locations. Day or night, rain or shine, it simply gets on with the mowing, leaving you free to get on with managing your business.
