this be awesome ... I hate sweeping , and now I do not have to . this go from tile to carpet with no problem . I have a large living area break into some odd corner , and this robot clean it all , albeit randomly and I can not figure out the pattern , but it get the room clean ! it seem to not get catch on too much . I have floor speaker with large basis , and it `` climb '' onto it , and sweep the dust off -lrb- it be like a half centimeter high base -rrb- . clean it be critical ... take a few minute at first to get the routine down , but go quickly afterwards . mainly empty the bin everytime , then every couple of time , pull the brush off and cut the hair out with a handy little letter envelope opener deal they provide . for those read this who hate the word `` maintenance '' ... the question be ... do you hate a few minute of maintenance after a robot clean you floor more that you hate sweep ?? lol ... I do not ! we 'll definitely be buy a Scooba as well next year !
