this is our 2nd samsung smart vacuum. the first didn't seem very smart - couldn't find its way back to the docking station, got stuck under chairs, etc. this one seems to work great. we put the station in the laundry room at one end of the house. the vacuum mapped the house first, now cleans the entire house (has to recharge once to finish) and finds its way home every time. seems to do a good job cleaning. only real negative that i can see at this point is the bags - great for hypoallergenic, but costly to replace. and with 2 dogs and 2 cats, it looks like it will fill up pretty quickly. all in, i'd recommend it.
