Roomba and Scooba

["Ho Yin Ng" <architect.hoyin@xxxxxxxxx>]

I am considering buying a Roomba and a Scooba for washing my rubber
floors. My idea would be to set it up and let it trundle around and
clean the floor whilst I am at work.

The problem is I have never seen one and don't know of anyone who has used
one.

1. Does anyone on this group have either a Roomba or Scooba?
2. Am I able to program them as described previously so they can clean
whilst I am out?
3. I assume if they run out of battery power they will return to the
cradle to recharge then carry on cleaning?
4. How does the Roomba cope with crossing door thresholds from one
room to another?

I have seen the Roomba 560 on sale, is it worth it over the 530 - am I
right I needs the 560 before I do scheduling? My rooms that actually
have carpet is minimal my main areas are rubber. I cannot find a UK
seller that sells the Scooba.

Thanks
