Have we the 380t Braava! purchased directly from the manufacturer. Difference: 2000mAh battery and fast charging station is. We had two Roomba with which we are very satisfied and have after much back and forth opted for the Braava. The products developed by iRobot models told us not quite to as the does not seem to be sufficiently mature to the water tank. In this model, a dry or damp microfibre cloth is in the appropriate holder clamped Cube set up and go! The Cube is a kind of indoor GPS that works very well. Have tried it with the microfibre cloths and with Swiffertüchern, me personally the cleaning result with the microfibre cloths like better. For a thorough cleaning but not suitable to keep clean un ideal! We have two small children (8Mon. / 2J.) So that had to be / cleaned daily after meals our kitchen floor else several times. This creates the Braava if you do not wait until all the dried beautiful! The only thing I am annoyed is that we have not bought it sooner!
