I'm really happy with this purchase, with bitch-old I had to vacuum and mop every day mainly in the kitchen is the room where it is most. Today I run my Roomba robot Scooba sucks then that washes and while they do the housework I go about my business. The only small complaint for the Scooba is his little self, you can not ask him to wash only a small area like the kitchen, bathroom or toilet. We must therefore make choices because its capacity does not exceed 2 times 20 minutes. Nevertheless I appreciate his work.
