## Features

- AUTOMATED ROBOTIC LAWNMOWER: Capable of climbing slopes as steep as 25 degrees, the ACFARM robotic lawn mower is a simple choice for small to midsize yards with steep hills. Its efficient brushless motor is powered by a 20-volt 4.0Ah lithium-ion battery that produces 80 mins of runtime per charge. It mows up to 1/4 acre on schedule. Rain, tilt, and impact sensors allow it to operate safely.
- RANDOMLY CUTTING PATTERN: It uses the three-blade rotating disc-cutting mechanism. It has a 7-inch cutting width, The mowing height manually adjusts from 0.8 to 2.4 inches. It works to a randomized cutting pattern but after its first full cut of the lawn it looked lush. So bear with the zigzag patterns on your lawn for the first few days and eventually the whole sward will look evenly mowed. This leaves a very good finish, incredibly neat with no missed patches.
- DIY INSTALLATION: Assemble the base station, make sure that the wiring starts at the base station, around the perimeter, and ends in the base station to create a full and closed loop. Plug in the AC cord, insert battery into the mower, and install the app. The perimeter wire is a vital component that tells the mower when it's reached the edge so it doesn't run riot through the roses or tumble into a void.
- SMART APP CONTROL: It connects to your phone via Bluetooth or WIFI for easy scheduling, readily available as an app on your mobile phone, you can adjust the schedule and set up your phone without having to bend over the mower’s control panel. You can program your mower to cut any time, day or night, as the mower has a guaranteed noise level of below 60 decibels.
- HIGH SAFETY AND LONG LIFE: The robot lawn mower Blue RR 500 has anti-collision sensors, keeping pets and children safe. The blades stop if the mower is picked up. It features off-road tires and powerful in-hub motors, allowing the robot to easily handle various complex lawn environments. When it gets low on battery or senses rain it automatically returns to its charging bay.
