The present invention relates to a canister type automatic vacuum cleaner having a cleaning head assembly 120, a vacuum canister assembly 110 separated from the cleaning head assembly, and a hose assembly 130 connecting the vacuum canister assembly and the cleaning head assembly. It is about. The vacuum canister assembly includes circuit assemblies 210 and 212 that are controllers that perform navigation and control functions 400 for the vacuum canister assembly and the cleaning head assembly. Alternatively, the controller can be separate from the vacuum canister assembly and the cleaning head assembly and is movable. The vacuum canister assembly and cleaning head assembly each comprise a propulsion drive mechanism 202, 204, 310, 314. The cleaning head assembly can be motorized or includes an air driven cleaning brush assembly 320. The cleaning head assembly may also include a microcontroller in communication with the controller.n n n n Cleaner, vacuum, control, sensor |
