Nothing. I last checked over the winter and the cast of small brands had changed and the machine designs had changed but still over priced and under powered.

I specifically looked for Roomba mower and found nothing current.  Maybe they gave up.

I'll go back and check in the next few days, cos I'm due.

I'm thinking a gas powered robo-mower would be more attractive in the American suburban market.

Same results here.  BUT at $1000 for one that can do 1/2 acre, it's going to be worth a shot for me on my disabled brother's yard. Roughly 100% ROI based on what I'm paying landscapers.  That said, I'm wary of taking on logistics, maintenance, & support ....but at 100% ROI it becomes a 1-season throwaway if need be.

I've got two rechargeable electric push mowers.  Take their mowing area estimates with a large grain of salt, that robot mower has to both cut and propel itself forward all off one battery. Plus variables, inclines, wet grass.

Keeping the blades sharp really helps.

If it will recharge itself and pick up where it left off  then you are good.  For a robot, most of the work is up front, doing whatever type of setup needed to keep it in the yard and teaching it what to do.

Neighbour just got one of these:

Its neat.  The lack of rain since he got it means its not working too hard.

Ooh, that's a beautifully produced video.

Bookmarked.

RC, narrow it down to a couple of likely models, then check Youtube for each model.  There are some handy tips in those videos.

One concern is about max mowing height.  One Husqvarna owner said he wished it mowed higher, because in the full heat of summer the low grass let sunlight hit the soil drying it out faster.  He had to run irrigation system more often.

For myself, I'd stick to name brands so you can get parts in the future.  The Husqvarna looks nice.

I can do the Arduino-coding and chassis-wiring if you can do the physical stuff like the wheels and the chassis? Can't believe the price of these tiny roboomowers Just needs some sensors and an OS!.

so Brad, whats your involvement...  you seem to know more about it:)

From a neighbour perpective, I can say....On a complex lawn the Husq does sometimes get stuck. For example sometimes it wants to cut through a hedge,  turns out the perimeter wire was too close at one point. to begin with it was running over the edge, where the perimeter wire was too close to the edge by about 1 inch.
 
So despite the apparent simplicity, I think there has been quite alot of RandD to get it to the stage it is:

  • If you try to nick it an alarm goes off.
  • It learns the complete map of the lawn, so if you have several separate lawns it knows to cover them all equally (Iain has a number of small lawns separated by paths). 
  • It has to know the state of the battery and where it is so it can get back. 
  • It works in the rain 
  • It has an app from which you can control cutting times cutting height, send it home, see where it is etc etc

I am sure there is more.

 And for 40 per year the supplier takes it away, services it and stores it in the winter for you, so no lawnmower in the shed, now 300 service bills or expensive belts. The blades are I believe replaced for that price.  In Austria there are huge sheds with 1000 of them every winter I am lead to believe .

Nah, I don't know much at all.  I think there are a number of old threads about various types of household robots here which caused me to look into these a bit.  Plus I've got a bad hip which gives me an interest in not pushing a mower.  What I really want is a snow shoveling robot and a rabbit chasing robot to scare off the varmints.

I think in the earliest discussions here, the robot mower companies were all small and the mowers crude.  Some of those companies have survived but some bigger names have moved in too, all of which is good.

Rupert, your info is fascinating.  I got the impression from Youtube vids that the UK was way ahead of US in adopting these robot mowers, I didn't realize the Continent was also onboard, but it makes perfect sense.  And thinking of these mowers as a service rather than a one time sale opens up lots of business opportunities for someone.

I think the 40 is a very low entry offer.  It makes sure they are in touch to supply the next one, as well as all of the others stuff he sells. Be surprised if lawn treatments are not added to his sales pitch .  If he gets 100 like that, then it might be worth it for him.
