Obviously since the 972B model in a canister type vacuum, it includes a removable canister that can be both emptied and cleaned; but the device also includes a convenient bag change indicator to help keep the vacuum peaked at top performance (vacuums pick up a considerably less amount of impurities when the bag is full). The Eureka Maxima 972B vacuum includes additional features such as an automatic retractable cord system attached to a convenient button, standard filtration support, a handle that adjusts to the user's height, a special suction control switch which isolates direct suction power to the area needed most while cleaning (hose, or floor), and a steel telescopic wand or hose attachment.
