The loyal and faithful iRobot Roomba Discovery SE – Model 4220 will clean your house without ever asking for anything but a plug and maybe a little backup if it runs into the cat. Roomba senses and finds dirt. Once dirtier areas are detected, Roomba automatically increases the intensity and focus of its cleaning.
It’s generally not Woot’s policy to link to outside sites, just like it’s not the iRobot Roomba Discovery SE – Model 4220’s policy to leave any dirt behind. It has two Virtual Walls that can be programmed to keep your Roomba out of off-limit areas. Roomba has the built-in intelligence to automatically return to its self-charging home base when its battery is low or it has completed a cleaning cycle. This means your Roomba will always be charged and ready for its next cleaning mission. Not bad for a household appliance ayt?
