Filter keeps clogging up ie what gets picked up goes into the filter not cylinder?

If the light goes out if you disconnect the hose, there's something in the hose or wand.

see this causes and fix it. God bless you
Air filter:
If the vacuum cleaner won't pick up dirt and has no suction the air filter might be clogged. Remove the filter and either clean or replace it as needed.
Exhaust Filter If the vacuum cleaner won't pick up and has no suction the exhaust filter might be clogged. Remove and clean the filter, replace it if its torn or damaged.


Vacuum Hose If the vacuum cleaner won't pick up and has no suction the vacuum hose might be clogged. Remove the hose from the vacuum cleaner, stretch it out straight, shine a bright flashlight in one end and try to see light through it. If no light can be seen, use something to run through the hose and free up the obstruction.
Vacuum Bag If the vacuum cleaner won't pick up and has no suction the vacuum bag might be full. Clean or replace the bag as recommended by the manufacturer.

Dust Cup AssemblyIf the vacuum cleaner won't pick up and has no suction the dust cup assembly might not be installed tightly, or it might be cracked or broken. The dust cup must seal tightly in order to produce the right amount of suction. If it is cracked or broken, replace it. Most glues and adhesives will not successfully seal the crack.
Blower Wheel If the vacuum cleaner won't pick up and there is no suction, the blower wheel might be jammed or broken. Check the blower wheel to be certain it turns freely. If it doesn't, check to see if there is anything rubbing against it. If not, but it's hard to turn, the motor is most likely the problem.

Mine did the same thing - unfortunately, that means it's dirty. When they recommend a good cleaning of the filters every 3 mths - they mean it. The filters may not look dirty, but if you skip cleaning them (like I did) - those tiny little particles build up & then clog the filter. The bottom filter is not cheap - you can pick it up online for about $55, considering the alternative (running the Dyson w/o the bottom filter - and yes it will run without it) which may result in damaging that very expensive motor - go buy a new filter. It's cheaper than buying a new Dyson or replacing a burned up motor.

Always use the foam filter when using the Shop Vac, keep your filters clean and it will operate more smoothly. When sucking water I usually take the foam filter off as well as the cylinder filter

Generally the Hepa filter is a bypass filter in which there is another filter on the unit. Check to ensure that the belt is allowing the rollers to turn the brush. Just suction on the line won't pick up deep dirt unless you allow to sit in place.

Check the tube that leads down to the brush head for clogging as well as any motor or HEPA filters. If that still shows nothing, take the cover off the brush head (like you're changing the belt) and look for obstructions in there. Usually, if you have low suction on the accessory hose, the problem is with a motor filter, HEPA filter, or a clog where the hose goes into the unit. If you have good suction on the accessory hose but none on the floor, it's usually in the brush head (clog or broken belt) Good luck

That is the problem with the bagless cleaners. The dirt goes through the cup, directly to the filter. There is nothing to keep them seperate. You can try putting a single layer of paper towel against the filter. It will provide a breathable barrier for the dirt but, it will clog too.

disconnect the hose where it goes into the clear tube on top of the base.there will be a little flapper door there when yo take it off.open the door and take a coat hanger with the end bent over like a hook and pull the dirt clog out of there.but first take the dirt cup off and remove the filter,if its clogged with dirt you won't have any suction.try using the vacuum without the filter in the dirt cup.if you have suction then then thats your problem ,a cloggeds filter

I no more use Eureka 4331 (Boss Lite). But the most common reason for not picking up dirt might be the vacuum bag might be full. Need to be Clean or replace as recommended by the manufacturer or The air filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner's manual for cleaning instructions. I recommend having Eureka Power Speed for yourself.

You may have a clog in the hose, and/or the inlet by the brush roll. A clog will turn on that light as well as a full bag.
