Hello, I think so, but the best thing is to ask the manufacturer. He's the one who gives the guarantee. This model is really great. I've seen it rated badly, but for me it's worth 6 stars.
According to the manual, the sum of all areas or zones must not exceed 1,500m². This has nothing to do with the battery capacity. It is nowhere near enough for 1,500m². In one of our zones, which is 218 m² in size, the battery charge drops to approx. 30%. This makes it clear: 1,500m² will require multiple recharging. As you can set the speed (m/s) (0.5 for us, default 0.3), you can influence the mowing time.
