Auto Robot Mowers

How do they cope with things inside the boundary wire? So I have a couple of beds inside the area of lawn. Do they just bump into them and turn or do they need a wire around them?
If its a flower bed it needs to be wired off, trees or shrubs aren’t a problem, it bumps them and turns around.
 
Had a Husqy 305 in the last place. Just bought another one for the new place. There are cheaper mowers but these have a guide wire which, amongst other things, allows you to program the mower to drive down the wire a predetermined distance and start cutting there for x% of the times it restarts. I think it will allow 3 locations.

The lawn was much better after being cut with a robot. More practical and the wife liked it as the lawn always looks cut.
 
How good are they at navigating borders/twisty bits of garden,
Excellent
getting in nooks & crannies?
Depends on the size definition of nooks and crannies. They can find it hard to get into them depending on the geometry (hence Husky guide wire). However if it is a small area and it bounces around in it without being able to find a narrow exit then they will wear the grass out rather than cut it.
I can see they'd work in modern, small straight gardens.
Work well enough in any garden if there is a big enough exit/entry to each area but if it is a complex shape you want to have some automated method of getting it to the more distant areas on a restart so all the grass gets cut equally frequently.

Some models map the area out by driving round the wire and then planning a systematic cut rather than using an algorithm to bounce around 'randomly'. The upside is that everything will get cut regularly, the downside is that there may be missed bits until it has been cut a few times and the regular cut path may form tracks. Which is why most models do the 'random' approach. I think
 
My neighbour has one, it’s a husky. Lawns look very good. Seems they have it set to go off in the morning so assume it goes well on the dew.
 
Do you need to prep the lawn and level/smooth it out before you get the mower? Or will it cope with a bumpy lawn and eventually as it cuts every day it'll grow out and level itself as such?

If it keeps getting stuck on a particular bump you need to sort it, otherwise not a problem.
Theres a lift/tilt alert on mine that gets triggered every so often, but generally it just trundles away on its own.
Definitely worth the price.
