I love my i-robot! it cleans all floors of the house knows how to ride on carpets, insists the dirtiest places, makes angles, passes between the bars of chairs, under the sofa and beds short, it works better than me! of course we must place everything that drags but it was not we already? it makes a little noise that is true but much less than my big rowenta! we can let him throughout the house but I like to put in one room, close the door and let him work. it makes the room thoroughly, honestly not need to go back, it suffices to note that there has in the recovery tank emptying after each use but hey there's more than that to do! This fabulous invention will accommodate everyone! we have back problems, which is a working mom or bachelor of hard work, we have, in any case, far more interesting things to do than vacuuming! this model is not programmable but it does not matter, it is put on the road before you leave and when you come back everything is spot on! I will go and order one for my mom, to 76 years, although it is rather in good shape, effort and contortions that require vacuum cleaner is not suitable at all to his vertebrae. it will change his life! I recommend ++++
