The Landroid is a battery-powered robotic lawn mower that cuts your grass on a customizable schedule and automatically returns to the recharging base when complete.

Mow time can vary due to several factors including your terrain, slopes, and the number of obstacles the robotic mower must navigate around in your lawn. The Landroid trims your yard on a customizable schedule, maintaining a consistently healthy lawn height.

The Landroid robotic mower has an app that allows the owner to adjust multiple settings and gather information about your Landroid. It is available at no cost on the Google Play store and Apple App store.

A quick start guide with easy to understand instructions is included with the Landroid robotic lawn mower. Installtaion takes anywhere from 3 to 5 hours depending on your lawn size and number of obstacles.

Installation of a boundary wire is required before using your Landroid. The boundary wire and lawn stakes are all included with the Landroid. We also offer customer care and support for installation questions.

The charging base for the Landroid robotic mower should be placed on a completely flat surface. A 32 foot (9.7 m) power cable is included. Place the charging base in an area that doesn’t get an excessive amount of sun exposure to prevent overheating of the lithium battery.

If you have an existing dog fence, the radio frequency from the dog fence could potentially interfere with the radio frequency of the Landroid boundary wire, rendering both fences inoperative. Landroid is not recommended to be installed within 3 feet (1m) of an existing dog fence.

While not necessary, the boundary wire can be trenched. The Landroid wire should not be buried more than 2 inches (5cm). Lawn Stakes are provided in the box to pin the boundary wire flush with the surface of your lawn.

The Landroid mows according to an algorithm which to us appears to be a random pattern. Since Landroid mows more frequently it will create a carpeting effect on your lawn leaving your grass completely even.

Landroid handles large obstacles by bumping into them and turning around. The Anti-Collision System (ACS) accessory is available as an add-on to help your Landroid mower sense obstacles via ultrasonic detection and navigate around them instead of running over or bumping into them.

The Landroid must have a gate or a path to move through the second cutting area. The Landroid can travel over a driveway to get to the secondary mowing area if needed, but the wires must be run through 2 separate expansion joints in the concrete.

The Landroid robotic lawn mower uses 3 razor blades attached to a rotating disc.

Cut-to-Edge technology is an offset blade positioned at the edge of the mowing deck. This allows the robotic mower to get closer to the edge of your boundary and reduce the amount of trimming needed to as little as 2 in. (4.5 cm).

Yes, you have the ability to transfer ownership of your Landroid to someone else through the Landroid account page ( Follow the steps below to successfully change ownership:

1. Ask the new owner of the Landroid to set up a new Landroid account for themselves
2. Log-in to the webpage and click “change” next to your email address (found under “Owner”)
3. Fill out the change of ownership form with the new owner’s email address that they used to set-up their Landroid account
4. You will both get an email confirmation when the transfer is successful

For replacement and additional parts please visit our Landroid page.

Yes, fill out the service request form on the support page to be contacted by our preferred partner about installation options.

For WR165, WR147, WR155 ONLY: Remove the battery and lift the front of your Landroid to spray the underside with a garden hose. Do not use a pressure washer.

The floating disc found on WR165, WR147 and WR155 assists the Landroid in traversing different yard types. The cutting disc "floats" and will move up and down over different terrain, which helps it avoid getting stuck.

LCD screens are more energy efficient and longer lasting than a traditional LED screen.

All Landroid accessories are compatible with the new models, EXCEPT the Off-Limits Digital Fence (WA0863).

Auto-Lock is an optional feature that can be activated in the Display. This option is currently only available for mowers with LCD Display.
