It transition from hard wood to tile to carpet. It's a little noisey but can get drowned out as time goes by that is unnoticeable. It's definitely worth it because it cuts floor cleaning down and when you start it it goes everywhere (under couches, tables) and when it's tired it goes and dock.

I haven't used the Roomba that I purchased at our local Best Buy yet since it's technically a gift for my wife, but I've got friends who have this model and they love it. I've seen it in action and I'm excited to use it in our home after Christmas. We've got wood floors throughout our home and I'm sure this will significantly help to keep the floors clean from the dust and dirt that our three boys track through the house, along with all the pet hair from our two cats and from our dog. Roomba makes a phenomenal product and I'm sure this gift will be well received when my wife opens it on Christmas. I spent a lot of time looking into other makes and models, but Roomba seems to be the best right now. I've seen other models that some of our friends own and I wasn't as impressed as I have been with the Roomba's that I've seen in action. So this is exactly what I wanted to get for my wife (yes, I also got her jewelry and other gifts that are not related to cleaning, but I know she'll love this gift!). If you're looking for a good robotic vacuuming device, look no further than Roomba!

Received it about a week after I ordered charged it for about 2 hours I was amazed at how much it picked up . Just make sure your pick up socks and things like that because it will find it and try to eat it . I have all hardwood flooring.

This robot works well overall. It goes back to its station whenever its on low battery. When it gets stuck it calls for help. It works well on wooden floor and on carpets.

I'm impressed with how well it cleans. There is a significant amount of dog hair collected by it. I'm not impressed with it's ability to dock itself. It runs around all over the place aimlessly unless you hit "dock" about 10 feet or less and pointing straight at the docking station. Easier to pick up the machine and place it on the dock station. So I never run it when I'm not home because it will just run the battery out. It also confuses what it is supposed to do at times. If you press "clean" it may do "spot clean." This model does not have all the bells and whistles, so these are just probably bugs with the earlier model. But again it cleans well for what I spent on it.
