    Once set up very impressive. It can be made to cut to the lawn edges but any depressions or holes in the lawn need to be flattened or filled in, particularly at the edges.
    Jointing the boundary wire to the required tension can be a problem with the supplied connecters.
    The sequence of button presses needed to programme the unit could be made clearer in the manual.
    Overall highly recommended if you can get past the setup process.

    Golden Review Award: 2 From Our UsersBrought this mower to see if it would help me as I hate to mow the grass well I agree with no 1 in this .
    1, if you don’t have flat grass this will annoy you when the wheels keep dropping in in even grass it will just shut down

    2, you need a 2.4 ghz Wi-fi to use this most new smartphone just run on 5ghz so will not connect

    3, I have had to either make the grass flat or like I have done (I am not recommending this ) is made the wheels at the front not lift so it just carry’s on as normal and works very well.

    If this is any help or if you need to know more let me know

    This is a basic robotic lawnmower. But it does everything you’d want it to.

    1) Get your lawn level – might need to add a bit of top soil to any craters and add some grass seed.

    2) Peg down a boundary wire. Takes no time. Bury this when happen if you want it to be invisible (it’s green anyway)

    3) Plug in, let it charge, press go.

    4) Tidy up and minor bits every few weeks. I use a cordless strimmer and it takes me 5 mins. No grass cuttings because you just send this mower out daily and it therefore cuts minute pieces which then fall onto the lawn fertilising it and encouraging a healthy growth

    I had seen these in action previously and thought they weren’t for me.I now find it difficult to use a normal mower due to arthritic knees.My son suggested that I try one of these so called robotic mowers,so I took the plunge.It has been working every day now for the last month,doing a far better job of my lawn than the previous mowers.I have bought many useful things in my lifetime,this is up there with the best of them.

    Great mower, excellent value for money and fast delivery. After setting up the boundary wire (included) the machine was easy to set up, just a few buttons to press and it was up and running in no time. As well as the boundary wire, it comes with plenty of pegs and also a base station to recharge. The rain sensor is very handy too. I am amazed by this mower and it’s so relaxing to watch it do all the work. What a great little machine!

    Golden Review Award: 16 From Our UsersI bought the Amiro 400 in April. Thisis the basic no frills model. Control is by buttons on the mower, which can be set to the number of hours required according to the size of the lawn. My lawn is just over 400sq. metres and the machine copes very well keeping it looking extremely tidy. I pegged out the boundary wire on the surface, 100m is supplied but had to buy another 50m, and over a period of a few weeks I had to move it in places to suit the mower. I have not buried the wire yet but will do so, that will be quite a long job! On the plus side the lawn is looking great and I don’t have to think about when I will have time to mow it. No grass clippings to worry about either. Negative comments would be the instructions are not great, and I would also advise to thoroughly level the lawn with a top dressing a few weeks before installing unless you have a bowling green (the instructions do advise this). It does not like even small divots and if it gets stuck in one it has to be rescued. Overall I would say good value

    Keeps the lawn looking good

    Golden Review Award: 16 From Our UsersDelivered quickly, really easy to set up, placed the boundary wire, pressed a few buttons and now my grass is being cut right now without me doing anything. No need for me to work out when I’m going to fit it into my busy life, would definitely recommend.
