Never had one before. Have hard flooring downstairs and carpet upstairs - quite like the idea of vacuum + mop (for downstairs) and also being able to connect it to a mobile phone. Also a must to have sensors and intelligent mapping so its efficient and doesnt go over the same area but does do a decent job in cleaning. Does such a thing actually exist? Keen to nab a deal in the Black Friday sales if so :) (I know they claim to but want to hear actual experiences)
