Is the LawnMaster OcuMow® 
DM16-150 Advance the right robot mower for your garden? Watch this video to discover all you need to know about how the DM16 Advance navigates and mows:

For optimal results, OcuMow® DM16-150 Advance works best on lawns with clearly defined edges.

Suitable lawn borders include:
• Paving or slabs
• Brick or stone edging
• Raised sleepers
• Gravel borders
• Clearly defined edges

Lawns that may cause issues:
• Grass that runs directly into soil or flower beds
• Very uneven or poorly defined edges
• Lawns with many permanent obstacles

Parallel Mowing Limitations
Border + Parallel works best on simple lawn layouts. Trees, flower beds and other obstacles may prevent the mower from cutting the grass directly behind them during parallel mowing. These areas may need  additional mowing using Parallel or Random Plus. 

Best Performance Tips:
• Remove temporary obstacles before mowing.
• Use the No-Go Strip to block off areas the mower should avoid.
• Start with a higher cutting height when grass is long, such as during spring growth.

OcuMow® DM16-150 Advance uses a High Dynamic Range camera combined with two ultrasonic sensors to navigate around your lawn. The camera enables it to mow in areas it detects as grass 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 on the lawn it must have visually distinctive borders. 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 performance make your borders clearly defined to improve edge detection and allow the robot to work correctly.

If the mower cannot recognise a clearly defined lawn edge, it may not stay within the lawn area. Bare earth borders which can become weedy, or flower borders with low plants can be interpreted as grass by the Optical Grass Recognition (OGR) software. For this reason, we recommend that either raised edges, a hard border of paving or gravel, or walls and fences are the best options around the lawn.

LawnMaster OcuMow® DM16-150 Advance has 3 modes to choose from: Border+ Parallel, Parallel, and Random Plus.

Border+ Parallel completes a perimeter cut first, then begins a parallel mowing pattern automatically. When the mower has completed a pass of the lawn mowing in one direction, it will change orientation and begin mowing in the opposite direction in order to cover as much of the lawn as possible. Obstacles and borders will be detected as edges and the mower will not go around them. Therefore this mode is better for simpler lawn layouts.

Parallel begins a parallel pattern working across the lawn from left to right. When the mower reaches the right side of the lawn, it will turn and complete a pass from left to right in the opposite direction. Again, obstacles and borders will be detected as edges and the mower will not go around them. This mode is also best for simpler lawn layouts, and gives you full control over where you start the mower.

Random Plus mows in a specialised random pattern developed for maximum coverage of the lawn. In this mode, the mower is more likely to cover areas behind obstacles, making it most suitable for lawns with fixed garden ornaments and furniture.

Unlike traditional robots the OcuMow® DM16-150 Advance is designed to Drop and Mow. The mower is designed to be placed on the lawn once or twice a week and will mow for up to 4 hours on a single charge covering 150m2. The mower should be stored away in a dry place between uses.

LawnMaster OcuMow® DM16-150 Advance will mow closer to the edge than our original OcuMow® 16, but will leave a small amount of grass uncut at the edge of the lawn as the mower will only mow in areas it identifies as grass. When it approaches an edge it will stop a short distance away. This is for safety and to prevent the mower leaving the lawn. 

To keep the edges neat, a grass trimmer should be used every few mowing sessions. OcuMow® DM16-150 Advance uses an MX 24V battery which is compatible with all our LawnMaster cordless 24V grass trimmers and can be purchased without a battery, saving you money. 

The OcuMow® DM16-150 Advance works with our MX 24V 4.0Ah battery. The mower will cover 150m2 on a single charge. Lawn coverage can be increased with additional batteries (sold separately).

OcuMow® DM16-150 Advance requires good light in order for the camera to function, this mower can only be used in the daytime. The robot will not operate outside daylight hours, making it friendly to nocturnal wildlife.

The grass is cut using three small sharp blades and the clippings are returned to the lawn surface where the nutrients contained in them fertilise the soil.

This means stronger, healthier grass with less need for supplemental fertiliser, and has the added bonus of helping the lawn retain water in dry periods. It also means there is no grass clippings to dispose of or compost.

Provided that the mower is used regularly, the grass clippings are not visible to the eye.

It is possible to use OcuMow® DM16-150 Advance on lawns with a pond, however it is strongly recommended that the pond is surrounded by a raised barrier at least 15cm high to safeguard against the mower falling in.

If a raised barrier is not possible, a paved/gravel border at least 75cm wide surrounding the pond, or continuous magnetic strip placed at least 30cm away from the edge can also be used. Ensure there are no gaps in the magnetic strip.

Water damaged mowers are not covered under guarantee.

OcuMow® DM16-150 Advance has a safety key which can be removed to prevent children starting the mower unsupervised. Safety sensors stop the blades if the mower is lifted or flips over. The mower is also equipped with ultrasonic sensors which will avoid obstacles higher than 6cm. We recommend that children and pets are not left unsupervised with the mower while it is operating.
