Your Questions Answered
Where do all the grass clippings go? Grass clippings are so small and unnoticeable they will disappear back into your lawn and act as a natural fertiliser.
What is mulching? Mulching is where the tiny grass clippings disappear back into the soil, and act as a natural fertiliser, to create a healthy lawn.
Do you leave it in the garden permanently? It is suggested bringing the mower inside for winter. Make sure the mower is fully charged before storing away. Keep the robotic mower upright in a dry free area from frost, preferably in its original packaging.
How high does the boundary wire have to be? The boundary wire should sit at or under the ground level – not raised above it.
Is it pet friendly? Certainly. The ROB instantly reverses if it hits any object and changes direction. The blades are positioned well under the mower, so even if your animal was slightly bumped, there is no chance of them being harmed.
How long does a full charge last for? A full charge from the robotic will last around 60 minutes.
How does it charge itself? When required, the robotic mower will take itself back to the charging station and re-charge.

    I use it for mowing the lawn. It’s a pleasure to see him out in the morning, working away by himself. I think, even if he were doing nothing, it would still be relaxing – better than a goldfish.
    And the lawn looks fine. 🙂

    Sometimes fails to park! Don’t know why it can park 90% of the time but then isn’t charging and not finishing the job.
    Grass does look neat and tidy when it is working properly.
    Overall a good product.

    Set up takes some time, my grass is kept tidy and with no effort he is cutting once a day and I am so happy with the purchase. Also my dog takes no notice as he trundles around the lawn. Sorry for saying he, we call it Robmo.
