Installation
I knew from my pre-purchase research that this mower would require a fair amount of time to set up, although it is still quite frustrating when you just want to see the new mower in action.
I set up the new mower when the lawn was in need of good cut. That way, at least the time spent setting up the mower would be offset by the time I would usually spend going round with my old mower.
The first challenge was finding a suitable spot to site the power supply. The base has to face in a suitable direction to allow the border to be mowed in a clockwise direction. This is clearly described in the instruction manual
The next step is installing the perimeter wire. This is a little tricky as you have to strip the wire yourself, made more complicated when my usual wire strippers broken. I had always assumed that the perimeter wire was mark out the area covered by the mower. I found out that the perimeter wire for this mower is used for its “golden source” around the garden. This means that the wire has to be away from the edge itself, without anything blocking the border so it can then map the rest of the garden. One thing I learned was to be initially lay the perimeter loosely with as few pegs as possible and then go back and fill in between the gaps. You also need to avoid placing any loose plant pots on the borders of your garden as the mower uses the perimeter wire as its primary path around the garden. It is also good to leave some excess wire for changes later, which can be done by pegging in a zig-zag pattern.
Using the Device
When the mower it first used, it follows the perimeter wire around the edge of the garden and once it has completed its route, returns to the dock, having saved a map of the garden. It will stop if encounters an obstacle and will ask you when it is in the dock!
Once this has been completed, it is free to mow. Compared with using a conventional lawnmower, the robotic lawn mower seems to take a far more circuitous route around the garden.
One problem is that it can easily get stuck in minor ditches so these need to be levelled out so it can move freely around the garden. If it does get stuck, it has to re-calibrate by moving back to the perimeter wire.
It also has problems dealing with fixed obstructions on the lawn such as play frames, which it keeps bashing into whilst it is trying to find its way past the obstacle. Unlike my robotic vacuum cleaner, it lacks detectors to prevent it hitting garden furniture.

It also often takes a long path around the garden when getting back to the dock as it seeks out the perimeter wire.
Specific Features/App
The “border cut” is a promoted as a feature of this mower. However, in practice I found that I still needed to use my strimmer at the very edge of the lawn as the perimeter wire cannot be placed directly on the border.
The accompanying smartphone app is intuitive and allows a smart mowing schedule that takes everything into account from the weather to days you don’t want it to mow the garden for example weekends when you’re out there. It’s easy to setup and use and that certainly adds ease of use to the system.
I have found it struggles to get to specific sections of the garden (for example on the other side of my path through the middle) — although it can get there very easily around the perimeter wire, it hasn’t quite learnt the optimal way to get there because it doesn’t “learn” as it goes so it makes the same troubles multiple times around really. I think it often just misses out some of these sections when it says Lawn Complete which is a bit frustrating, because there’s no simplistic way to set it off to only mow a specific section of the lawn (this would be a great feature in my opinion). Especially as it already has an image map layout of your garden — it would be a great feature (probably via software only) to be able to do several things:
* Draw out paths/objects that don’t move even if in approximated places so it can learn the exact place on its round
* Be able to draw a shape on the map of the section you want it to specifically do (some areas grow quicker than others or if something is missed out you can easily make it cover that specifically or if the kids are playing or their toys are all scattered in one section you can just eliminate that and come back to it later rather than not being able to run a 4-5 hour cycle over 400sqm).

Conclusion
I wouldn’t say at least I’ve got it to the point where I can go on holiday for a week or go to the office and expect to come home and find the lawn fully maintained for me and the device on the dock charged up nicely — it’s great if you’re around and can give it the nudge it needs when needed (if stuck) but at the same time it’s a gadget of sorts that makes your friends and family eyes light up with curiosity and a good conversation starter on the world of digital tech. If I assume I had to spend around 3 hours every 2 weeks on my lawn especially during the peak months of growing and it looked quite long after 2 weeks — I’ve probably simplified my remit down to about 15 mins every 2 weeks doing the edges and any other general maintenance and the odd kick here and there to get it out of the copious ditches I have that I’ve been trying to fill in on a case by case basis. So yes, it saves me time and from that perspective I’m more than happy as it stands — I’m sure there’s some other good models out there too so I wouldn’t necessarily say this is the best of all of them (I’m not working with comparisons in mind) but Bosch is normally reputable for reliability so time will tell if I made the correct choice!
