If you do not see screws on the bottom of the power head, the top of the power head removes. There are two screws above the area of the brush roller.
Like any home appliance, Eureka vacuum cleaners need repairs and cleaning periodically. One of the most common repairs is replacing the brush roll belt or brush roll. It is often necessary to remove the bottom of a Eureka vacuum cleaner to access the belt and brush roller of the unit. Most of the Eureka line uses screws to secure the bottom to the power head. There are a few models however that do not have removable bottoms.
Unplug the Eureka vacuum power cord from the electrical wall outlet. If you have a canister vacuum, disconnect the power head hose from the canister. There is a small button near the hose connection you press in to release the hose.
Lower the handle to the floor. Most Eureka vacuum cleaners have a foot release pedal near the left side of the power head wand on the back of the power head.
Flip the Eureka vacuum cleaner power head upside down and look for screws securing the bottom of the vacuum. There are usually four to six screws securing the bottom. One screw at each corner of the brush roll opening and a screw near each of the rear wheels.
Remove the screws with a Phillips screwdriver. Grab the rear of the bottom and lift it up. Slide the bottom forward to unhook he front tabs and remove the bottom from the vacuum.
