The filter probably needs a darn good clean. If it is clean, wipe the inside of the canister with a clean cloth to get rid of static.

Ho wdo I change the filter on the Eureka optima.. HELP!!! thank U !

open the canister like you are going to empty out the dirt canister. there will be a tab to push in near the back side of the machine on the lid of the dirt canister. It has a push tab at the back and a stationary tab that locks in at the front.

If you do not have a new filter handy, you can brush out as much dirt as you can with say an old tooth brush or paint brush. you will want to replace the filter on this unit at least once a year.

good luck.

Dirt is being trapped in the filter area instead of canister.

The canister has a filter as well. It needs to be replaced or cleaned. A damaged canister filter will feed dirt into the HEPA filter. (and the motor)
An improperly installed filter can allow dirt to bypass the canister filter and collect in the HEPA filter.
I suggest a new canister filter and then clean it carefully every week.
Here is a list of the filters for your vacuum.

The suction on my eureka optima stopped working but the roller still works, what might i do to fix it?

Hi there. Most suction problems are due to a blockage. Start with the base and look carefully for debris that is stopping air flow. You may have to remove the base plate to get to the problem. I am including a link to the manual for your machine. look on page four so see how to remove the base and check for blocked airways.

Very little suction? Someone give me an answer please.

You must have something obstructing the airflow. There is sometimes a small trap door under the vacuum where the brush is located. Open that door and see if there is something jammed in it. If you don't have the door, then there is an obstruction somewhere in the vacuum. You should also look in the hose.

Eureka Optima vacuum has suction at the hose but not at the floor. I took out the filter and it still isn't suctioning so I don't think it is the filter.

it sounds like you have a plug. check where the hose goes into the back of vac. it should have a clip remove this and see if there is a plug there

You have to install the filter in the dust cup lid first, then put it in the dust cup. There are some clips that filter will fit into on the lid. Also, take a look at the maual.

Buckaboo, you say the debris no longer collects in the cup? Does that mean you don't have suction as well?

The brushroll has it's own motor so the brushes spinning doesn't necessarily mean there's not a problem with the wiring, the switch, or the motor.

Assuming you haven't inadvertantly set the selector switch to floor when you wanted to use the hose or vice versa, try the following.

Start with the motor/impeller first. Take the dust canister off and turn the vacuum on. It doesn't matter if you turn on the brushroll or not as you're looking for suction.

With the vacuum on feel for exhaust out the front of the motor (by the secondary handle on the bottom. Also put your hand over the area where the dust canister sits. You should feel strong exhaust and suction respectively.

If not, then you should take it in to a technician as going any further requires disassembly.

If you feel there's enough suction, then it may be as simple as a clog. This vacuum has a particularly easy air path to check. There's a clear snap-on door on the bottom to check the brushroll and neck. Then from there it's a straight shot through the canister itself before dumping inside and going through the filter. If it's the hose, you can turn the end clockwise to remove it from the body of the vacuum and use a broomstick to clear any clogs.

If it's not a clog or filter then you may try cleaning the seals (one round at the bottom of the canister where the canister mates to the body and a rectangular one in back of that where the dust runs up and into the canister.

Good Luck!

Sounds like you have a clog somewhere. Check the filter inside the dust compartment, if is very dirty it won't allow ait to flow thru, Part #62132, DCF-H filter. Check the hose, take it off if you can and drop something in it to see if it comes out the other end, if it doesn't, then the hose is clogged. Check bown by the brush roll, the inlet may be plugged. Also if the belt is more then say 6 months old, you may want to replace it, I am sure it is strertched, part #61120B, extended life belt.
