LawnMaster OcuMow VBRM16 robot mower arrives fully assembled. Watch the video below to discover all you need to know about starting and running your robotic lawn mower.

How it Works:

The VBRM16 OcuMow® is very simple to operate. It uses a camera combined with two ultrasonic sensors to navigate independently around your garden. The camera detects the difference between surface textures and colours, for example grass or paving, and the ultrasonic sensors detect obstacles higher than 6cm, such as plants, garden furniture, walls and fences meaning there is no need for a boundary wire.

To keep the mower within the lawn area, your lawn must be bordered on all sides by a hard, visually distinctive border. This can be a flat border of paving, gravel or wooden boards, or a raised edge such as border edging, walls or fences. The mower can detect some edges that are not distinctive however for best and correct operation making your borders clearly defined will improve edge detection and allow the robot to work correctly.

For a quick video guide, watch the video in the Setting Up section above.

How to Operate the LawnMaster VBRM16 OcuMow® robot mower and grass trimmer:

The OcuMow® is designed to detect grass and move into areas it identifies as grass. If it cannot see a clear boundary it will continue to move into areas off the lawn and into plants that it may identify as grass. Trimming the lawn edge with the supplied grass trimmer before use will help define a better lawn edge.

During first operation it is important to monitor the robot as it detects edges to see where the boundary definition needs to be improved.

Step 1:

Trim your lawn edges with the included 25cm grass trimmer so that the mower can see the edges well and isn’t stopped by any longer grass. If your grass is fairly long, it’s a good idea to start the mower at a higher height of cut for the first mow and adjust it down on subsequent mowing.

Step 2:

Check that the lawn surface is clear of any tools, sticks, stones, toys and other obstacles which may damage the blades or undercarriage.

Step 3:

Remove the battery from the charger and insert it into the mower. Insert the safety key.

Step 4:
Press the On/START button and wait for the battery indicator to turn green and the mower to beep. This gives the camera time to warm up and any attempts to start the mower sooner will result in an error. Once the mower has beeped, long press the Automow button and then press START. The mower will begin to mow in a random pattern and will continue to mow until it runs out of charge.

Spot Cut Function:
If the mower has missed any patches of lawn, these can be cut using the spot cut function. To use this function, make sure the machine is powered on. Place the mower on the patch to be cut and long press the spiral button, then press START.

The mower will cut in a spiral out from where it was placed on the lawn cutting any remaining grass it may have missed.

Step 5:
When the mower has finished, remove the battery and place it back on charge for next time. Clean the mower underside with a clean, dry brush, and store in a dry place.

The mower should only be used in the daytime so that the camera can easily see the lawn surface, and should be placed into storage between uses.

Robot Mower Maintenance:

To replace the blades
1. Lift the battery compartment cover. Remove the isolator key and the battery.
2. Slowly turn the mower over. Place it on a soft and clean surface.
3. Use a suitable tool (e.g. a screwdriver) to insert into one of three holes in the blade disc to fix it in place. This ensures the blade disc is not turning when replacing the blades to avoid personal injury.
4. Wear protective gloves and remove all three screws and blades with a screwdriver.
5. Secure the new blades with new screws.
6. Make sure all blades can spin freely.

Cleaning the underside
It is recommended to check and clean the underside of the robotic mower regularly.
7. Press the STOP button and allow the blade to come to a complete stop.
8. Lift the battery compartment cover. Remove the isolator key and the battery.
9. Slowly turn the mower over. Place it on a soft and clean surface.
10. Use a soft brush or damp cloth to remove dirt, dust, oil, grease, etc. from the underside of the mower.

IMPORTANT: Do not wash the mower with running water.
1. Wear safety gloves to clean the blade disc, the chassis, and the front and rear wheels
thoroughly with a soft brush or damp cloth. Remove any lodged debris around them.
2. Make sure the blade disc can rotate freely and all blades can spin freely.
