Lack of Suction
There are actually several possibilities.
Check to make sure that the brushroll is spinning. The brushroll is responsible for virtually all of your pickup on carpet, and is the culprit for most complaints of "lack of suction."
If the brushroll is not spinning, listen at the head to see if the motor inside the power head is active. If you can hear it running but the brushroll is not turning, you have a broken belt. If the motor in the power head is not turning at all you may have an electrical short in the hose, the wands, or the main power outlet from the body of the canister; but before you get too involved check the power head for a thermal reset button. Some of the Electrolux powerheads are equipped with these, and some are not, so check your user's manual. If there isn't one, or if it isn't tripped, you'll need to look for electrical issues.
In this particular model it is fairly common for the electrical contacts on the wands to short out, so inspect the metal contacts to look for scorching, or melting of the plastic around them. If you have access to a VOM, check for voltage at the contacts on the end of the wand, and if it is not present, check all of the contacts sequentially back to the canister body to determine which part is not passing voltage. If you have voltage all the way through the wand, you either have a loose connection inside the power head, or the power head motor has burned out. If you have power from the canister body, but not through the end of the hose, either your hose has a short in it, or the circuit board in the handle assembly that controls the power head power has shorted out.
If your brushroll is turning, then you do, in fact, have a clog somewhere inside the power head, which a visual inspection behind the brushroll and into the elbow will confirm.
Best of luck,
