When switch to carpet, the difference is that the brush roller turns. When it is on hard floors setting it doesn't. Remove the base plate, remove the brush and the belt. There is likely something wrapped around the drive spindle or clutch.

Hello, this is Ava with Think Crucial.

If the dust cup is too full, there is no space for the dirt to go when you are vacuuming. To fix this, remove the dust cup and empty the it.

If your vacuum is still not picking up dirt after emptying the dust cup, there may be something blocking the airway. There are two places where you can check for a blockage: the dust cup air duct and the intake opening behind the brush roll. To check for a blockage in the dust cup air duct stand the vacuum upright and remove the dust cup. Now you can disconnect the super stretch hose and check for clogs in the air duct behind the dust cup. If that is not the case, to check for a clog near the roller brush lay the vacuum down. Next check the opening behind the brush roll for clogs. If there is debris, clean the opening with scissors, carefully cutting away any debris.

Uncleaned filters may also the reason why your vacuum has lost suction. To clean the foam and felt filters, remove the dust cup and pull out the two filters that are on the top of the motor base. Rinse the filters with lukewarm water until the water is running clear. Let the filters dry fully before putting them back into the vacuum.

If your vacuum is still not picking up dirt, you may need to replace it.
Unfortunately, if none of the other solutions worked, your motor is going bad. Most of the time a new motor costs as much as the vacuum itself and it is not easy to replace the motor. It may be time for a new vacuum.

Did you check the bearing to see if its tight or free those bearing are probably in the brush ends

If this is new and returnable then I recommend an exchange. If not possible check to see if the vacuum has an internal fuse on this model. If not, use a voltage tester and test power to and from power switch and to the motor itself.

The 2 metal pins of the motorized brush are not in contact with the vacuum cleaner. or the Motorized brush is clogged up. You have mentioned that it is cleaned, but still give a thorough inspection. For the metal pins, firmly insert the motorized brush into the air-intake nozzle. This will connect the motorized nozzle to the unit power supply.

IT SOUNDS LIKE YOU HAVE A BROKEN BELT, THAT CONNECTS THE MOTOR TO THE ROTOR BRUSH.

This may sound silly, but have you checked the belt? A lot of Eureka vacuums use the vac motor to run the brush, and if the brush is not running the vacuum won't pick up. Another thing to check is the condition of the fan blades.. if they get worn they will push air out of the exhaust ports, but not push enough air to pull the dirt into the vacuum bag. Another thing to check is the length of the bristles on the brush... you can change a lot of the bristle strips and save the cost of a whole brush roll.. All of these fixes are under $10.00 (Belt: $1-2, Brush Strip $3-6, Fan $5-10) at most places.

Batteries are getting weak. They usually only last 3-4 years. Is it a replaceable battery pack?

The front brush motor will not engage until the power is turned on and the handle is in the down position. In the upright position the brush motor wont engage. Typical faults will be the belt is broken and needs replacing or the fornt brush motor needs replacing.
