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.

    Better than a goldfish.
    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. 🙂

    Takes longer than I was expecting.
    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.

    Robotic mowe
    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.

    Golden Review Award: 4 From Our UsersOne of my best buys eve
    I am a typical bloke, boys with toys and like a little project. I installed this on my bit of grass which is about 1200 sq m i.e. right at the top end of the spec for this very reasonably priced machine. Sure it takes effort to familiarise yourself with it and definitely to set up the perimeter and remote guide/home wire (if you need it). Also a couple of weeks of fine tweaking as you learn where you have pushed your luck too far with the wires. So key bits of my experience of this are:

    1. The guide wires, even though green, do attract initial attention and comments (generally negative). Relax, in 6 weeks the wire will have pretty much disappeared as the grass grows around it. Mine is now invisible.
    2. Do cut the grass before you set the machine going – it isn’t designed to do a big/proper cut that you are used to. Do not expect a sudden miracle.
    3. Don’t be put off by the random nature of the cutting. Provided you match the cutting times to the size of your lawn, it will all get cut mainly when you are not looking.
    4. Do swap the blades every two to four weeks and in between reverse them to use the other cutting edge (not in any of the instructions!). They are cheap and at the same time you can remove grass build up. Takes five mins max.
    5. Be patient. After about three weeks it was clear from the margin grass (the bits beyond guide wire) you will really see the difference between the two. After four weeks things will start to look really good.
    6. Do pick up sticks and large leaves that fall on the lawn.
    7. After about 8 weeks or so, marvel at how your grass now looks like a carpet (honestly). All cut to the same length every day, lovely and green (I have mine set at about three quarters cut height – no point in setting it lower IMO).
    8. FINALLY, after you have named your mower, try not to waste too much time watching it. It is addictive and everyone who visits comments on it and the result.

    While this product has been great, especially value for money, it has inspired me to but a way more expensive one (Ambrogio 4.36 @ 3,700) for my much larger area of c. 4500 sq m. Once you have one (or more) of these things in your life you will wonder why you didn’t do it sooner.

    Cheaper than a sit o
    The set up time of installing the wires a lot longer than expected as dug them in. Needed more cable and a longer low voltage cable which increased the initial cost. Although still need to cut around the edges the remainder is well looked after by the robot. Grass is more even and looking healthier. It’s entertaining sitting watching it cut.

    MOSTLY GREAT
    Although quiet there is some high pitch noise from the blades .
    minimum cut is 2.5 cm so its no daisy cutter and as I have a dog I don’t want to use lawn weed killer

    The fact that’s the minimum cut is the most disappointing thing about it .

    I have a lot of plants so leaves and debris can litter the grass around the edges Once every 2 or 3 months its useful to just hoover them up with the lawn mower
    but to do this you need the boundary wire buried
