Is there a roomba for just hardwoods?

didnt know if there are any special features, or if anyone has one?

the dirtdog is a sweeper probably the one you should get.. if you have any carpets though I would use the roomba.

I would use the dirtdog and also get a scooba

I would avoid the scooba. I bought one at Target for 75% off. We tried it a few times in our living room (about 23 x 13) and the dirty water tank would get filled up about halfway through. we would empty it, refill the clean water, and it would forget where it left off. Then, before it would empty the tank a second time, the battery would die out. Six hours to charge it. It took 8 hours to clean one room. No me gusta.
