Here are a few points of criticism, but all can be bear in my eyes:
For heavily soiled floors have to let him wipe frequently and possibly the room with a virtual wall a little smaller. This is probably also the fact that the Scooba sucks not all handed out water again (guess about 90%). With regular use, there is not the problem but.
While Scooba can go down abysses smaller but no longer comes up - for example, ceramic hob :)
With bumps in PVC Scooba depends somewhat fixed. Twice he has not managed and given an Error 'Contact Service' by itself. Switched on again did not help. The German Support said I should send in him and sent me return label. However, he went back the next day after being charged and I refrained. Support is courteous, albeit somewhat overloaded. Unfortunately, leave little parts of the device exchange. Best call by phone, if something does not fit - the mail response times are much too long. When sticking it loses neat water, so then possibly a small puddle is present. The wheels then rotate through also, which is not the escape from the bump of course very useful.
Scooba has also always ready to run, because it takes the steps sequentially (applying water, scrub, water imbibe). This way you can not cancel the wipe. In addition, it is not clear if an error occurs if this process is then still respected - especially if you turn off to him briefly.
After these 40x Wipe the middle row of bristles of the floor panel is already clearly filthy. But this is understandable.
So far, charging has about three times did not work (no fading / flashing). I therefore had to take again the power supply.
