GoKawiilRoborock's $3,200 Rockmow Z120 mower handles 39-degree slopes but struggles at edges
Roborock's flagship robot mower, sold as the X120H Lidar in the US and Z120 Lidar in the UK, uses Lidar and AI vision instead of satellite navigation, paired with 4G connectivity and a three-year data plan. It offers four-wheel drive with independently pivoting front wheels, a 9.5-inch cutting deck, coverage up to 21,500 square feet, and the ability to mow slopes as steep as 39 degrees, running 110 minutes per charge.
