We use a Rumba at home. Does a good job but we still have to vacuum.
There is another one of these type things. We bought it but returned it because it would run off the stairs. however it covered the entire floor in a steady back and forward.
I'm thinking of getting another one, if i can remember the name.
Don't use it in our Mh because it is not that large.
We have a Dirt Devil central vac that does pretty good. We have a rechargeable vac that we use a lot but it is not that great.
We had another in our fifth wheel that the charger burned up and it did great.
We need a rechargeable with a beater bar.
