Robot lawn mower question

Albe

Hello,
we are toying with the idea of a robot lawn mower. If/when we buy one it'll probably be Einhell, because I have already many Einhell tools and batteries and are all good.

Question: what's the meaning when manufacturer say "this mower is good for up to so-and-so lawn area"? The width of the blades? Or the max battery capacity it can holds?
I thought provided you can attach a large enough battery any lawnmower can do any lawn size, like saying any car can drive any distance, at worst a small car would be slightly slower.

Wrong?

Haven't read through this but might answer your questions

Could be a couple of things . Range might not be able to find its way home . But the most like is probably size , if its suitable for 10 square metres and your garden 50 square metres you'll need more robots according to the manufacture, it may take it X amount of time to complete a certain amount before charging etc.

I think it's mostly to do with the battery. The next one up from the one we have just has a bigger battery but is otherwise identical.

Bigger batteries are heavier and will take more energy to move round the lawn. So just adding a bigger battery might not give you much more range. There will always be a trade-off between power, weight and duration.

Thank you all for the opinions.

Resuming this old thread.
I'd like to have a robot lawnmower. But they are still very expensive.

Do you have one? Which one? Comments?

How secure is your garden?  They are eminently stealable.

Never had one but I know several people who have and love them.   Make sure you get the best you can afford and read all the model reviews before buying.   It can be expensive laying all the extra wiring to control its roving range if your lawn is a complicated shape or has island beds.

We have a Worx Landroid. We chose this because it can (in theory at least) cope with a sloping lawn and many of the others can't. In general it has been satisfactory although we do have a few problems with him flinging himself off the edges occasionally. I think the Worx models are relatively cheap compared to some other brands.

Thanks.

Our garden is very open, but the area is very safe. We own many bycicles, never locked any, none ever stolen. Plus, I read these robot are PIN protected.

Yes, our garden has a couple of islands.

If we decided not to buy one now it simply means we'll buy sometime later, hoping technologies/market progress and prices go down...

Our garden has an island and the boundary wire copes ok with that. The only issue is that the mower doesn't do a boundary trim around the island automatically but only if we tell him to.
