What is the detection range of the ACS accessory? ACS will detect objects that are 5 inches high, and begin to detect obstacles that are within 8 inches of Landroid.

Typically, Landroid will bump into an obstacle and turn around. Anti-Collision System (ACS) accessory helps your Landroid sense obstacles via ultrasonic detection and navigate around them instead of running over or bumping into them.

ACS will detect objects that are at least 5 inches high. Smaller obstructions that are closer to the ground like dog toys or sticks will get pushed away or run over by Landroid and could get caught in the cutting disc.

Installation is easy, first remove the cap covering the cables inside the mower. Once this cap is removed attached the cables from the ACS accessory to the appropriate cables on the mower. Use the hex screws provided to secure the ACS onto the top of the Landroid. Be sure to enable ACS in the Landroid app.
