Hello,
Here a Gardena robot has been doing loyal service for 5 years. They are identical to Husqvarna, most of the parts usually have a Husqvarna part number on them.
Important, don’t buy too small in terms of power if it’s not supposed to run 24/7. The specification of the sqm that the mower can handle usually refers to the 24/7 operation. Better divide it by 3 or 4.
Best regards,
Andreas
