My vacuum was working perfectly until recently, when the suction has ceased to exist when the main big floor attachment is attached. If I remove it, I can feel the suction, but with it on there's nothing. Nothing appears to be clogging the attachment and there are no visible cracks or holes where air is escaping.
If you've tried several different attachments and they all exhibit the same poor suction problems, you should completely check the parts of the vac that are common to all the parts that have the problem.
Since the motor creates good suction without attachments, I suspect the problem is the hose. Either an obstruction or a crack. Typically, if you block the end of the hose, the pitch of the motor's sound will go up slightly - like it it is spinning faster (it is). You can keep removing parts from the vac intake until the motors sound decreases - and that will indicate the part that has the obstruction. If it is a hose, you should clear the obstruction with a "snake" or other object like a pole.
If the motor sound does not change, then there is likely a split or crack somewhere between the intake of the vac and the device. You'll have to check it carefully - or if possible - connect it to the output of a vac and seal / cover the end. Feel along the length of the hose, etc. for air being blown out. Repair the opening and you should be "good to go"
Good luck!
SOURCE: The vacuum has suction but
The hose may have one or more leaks or bad connection. The most common place for a large leak is at the connections to the machine and the connection to the handle.
I've seen some reviews that mention little or no suction when using the floor attachment.

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,

SOURCE: Suction only through attachment, but not without attachments
have you removed the bottom plate...as if you were going to change the belt....look for where the intake hose is under or near the roller brush...most likely that is where your clog is.
Have you checked the floor head? Use a pipe cleaner or twisted metal to carefully and gently see what's in there. It sounds like dirt or something has definately sealed up the main suction channel.

If you have suction as you say, the tool is faulty.
They come apart so you can clean them. remove all hair and debris from the roller brush (use a coin to split it using a quarter turn on the two/three screws). Try turning the brush with your fingers. If it is stiff, it needs attention to the bearings in the tool probably. If it turns OK, then the mini turbine inside is faulty -- replace the tool.

I've tried some of the other attachments that came with the vacuum and they don't work either. Overall suction is a bit weaker than it should be as well, I think. Trying to figure out whether I need to buy a new hose or whether the problem could be elsewhere.
If I can feel suction strongly at the base when I remove the hose, does this mean that the problem is likely in the hose or wand, or could it still be some sort of internal/motor issue?
