The GARDENA SILENO City can handle slopes up to 25% (which is around 14 degrees), according to the manufacturer.
That's pretty decent for gardens with moderate inclines. From our research, it seems to do a good job on these slopes, cutting evenly without slipping or drifting, as long as the ground isn't too wet or bumpy.
But if you've got really steep or oddly shaped slopes, you might run into some trouble. In that case, you might want to look at other models built for tougher terrains.
