How is the Honda Miimo 520 Installed?

Installation is not included in the cost of the mower and although you can do it yourself laying the boundary wire can be a big job so it’s advisable to ask a local Honda dealer the cost of installing the mower for you. The extra cost will depend on the complexity of the lawn, but is usually between £350 and £400. The dealer will assess the shape of the lawn and then use a cable layer to bury the boundary wire around the perimeter of the garden and any obstacles such as trees or flower beds. The time this takes obviously depends on the size of the lawn but the cable layer does makes it incredibly quick.

If you do decide to do it yourself installation guidance and tips are available on a MiiMonitor App and there is a useful lawn planner tool on their website that finds your lawn in Google maps and then shows you how the Miimo works over a week of cutting.

Is the Honda Miimo 520 easy to programme?

A dealer can also take you through programming the mower explaining each command and feature to you and setting it up to mow exactly when and where you want it but the keypad and is simple and straightforward to follow for changes to the programming once they have gone. The accompanying instruction booklet is also clear and easy to follow. Changing the height of cut is simple, just a twist of a dial on the top of the mower, although the numbers on the dial are not clearly visible.

How well does the Honda Miimo 520 cut?

The Miimo 520 can tackle the largest area of the mowers we tested and also copes well with sloping lawns up to 45%. It’s very smooth, quiet and unobtrusive when its mowing its three, free-hanging blades cut the grass well. 360 degree sensors help it turn away when it comes near obstacles or pets and the blades automatically stop when its picked up. It turns smoothly when it approached the boundary wire rather than backing up like other mowers and is waterproof, cutting well in any weather. Clumps of lush grass are dealt with by the spiral cutting option which mows round and round the grass until its cut.

What Features does the Honda Miimo 520 have?

The Miimo has a seasonal timer which adjusts the cut to suit varying growth rates and an edge cutting function. It can also designate different start points for more efficient mowing of awkward shaped lawns.

For security it needs a PIN code to operate it and it also has an alarm the operated by a only and also has an alarm.
It doesn’t however have any connectivity options.

Is the Honda Miimo 520 good value for money?

This is a smooth, quiet, well made mower that copes with large areas well, it’s just a shame it doesn’t have more features for the price – at £2399 this was the most expensive mower we tested. It does come with w 5 year warranty if bought in 2019, after that it drops to just 2 years.

Are there other Honda robotic mower models available?

There are three models currently available covering areas from 1500m2 to 4000m2 and prices range from£1,799-£2,599.
A new, smaller model is due in 2020.
