I use my roomba in our 5th wheel and plan to take it when we hit the road. Like Matha said it doesn't get in all the corners but does a good job in the layout of our camper. I just get out the mini hand held vac once in a while and get the corners and stairs. I no longer keep a larger, heavier vac in the camper. I set the roomba to run each day and it keeps the rugs and flooring pretty clean. Now I just need a cat to ride it for entertainment
