So starting with dissect its flaws. I should state first that I mostly as tiles on 120m².
all included accessories are double, hence its high price.
I think Roomba too large to pass through tight corners. the pan is too small, so it must be cleaned often, even in the midst of a suction cycle times. when he draws a carpet - and it easily passes tiled carpet, which a little high, almost 1cm - the fibers quickly fill the tray. So we must always be there to watch. So if you have carpets or as carpet .... it would take a aspi with a much larger tank.
Quick? where a human would put 5 minutes, roomba it needs 20 minutes, and I'm optimistic.
Effectiveness? the people who wrote it was not effective have not understood how it works and compares it to the spatial logic of a human being vacuumed. I aspirerais a zone then the next one, etc ... it makes him go back and forth, sometimes crossed. so it does not suck the areas of next one after the other. but the end result that counts. there, it's not bad at all, except some corners, and provided that let him work in his own way and not the timing.
I put in a room, after putting aside anything that could impede, electrical son, objects on the floor ... and I press the "clean" button and here launched. when he finished, or when the container is full, it stops. I then put it in another room and he reworks. when the battery is discharged, he heads alone as a great base to which is connected to an electrical outlet to recharge.
You can program it to suck at fixed times. There is not much to understand to operate roomba. PDF User Guide and the site irobot.com the few things he has to learn it.
Just be aware that a "vitual wall" prevented from approaching a meter or two, or more, depending on what is indicated by the lower button on the tag came with.
the "lighthouse" is for me, a kind of GPS that tells Roomba geographically from home. it helps to identify the house to do his own programming to clean housing, without spending too much time in one area at the expense of another, and return at the end of work, enjoy a rest deserved to its battery charging cradle.
Here I hope to have contributed a bit to help you make your choices for buying Roomba.
