I have had one of these cleaners for about 3 years. Mine is a Irobot. They work very well and I would not be without one. You can now get them with a docking station and they find there way there ,and start recharging. I would however, say that I do not think it would work ok, if you went out and left it. They tend to get trapped under certain furniture. Usually you are not in the room, but they give an audible sound when this happens. You get to know which furniture is involved and can prevent this by blocking its path. I hope this helps. J
I have a "cheapie" knockoff of a "Roomba". Did it work? Yes, within limitations, it was great. It sounds like a cop-out, but if you start with a really well vacuumed floor, it kept the dust at bay very well. It didn't mind complex furniture, curtains down to the ground, etc, but it wasn't keen on pet hair, however. It did have quite a limited dirt capacity, so needed regular emptying. It was very good for going round behind sofas, chairs, etc, where there wasn't much dirt/cat fluff, just dust and the like. Saved moving furniture about. I don't think it could replace my vacuum, but I'm a dirty bugger, really. It did do an excellent job of dirt control. Mine came from Ebuyer, and they are currently selling a similar model for around £50 click here . It doesn't get a good press, unlike the earlier one I have.
