If I put a smaller diameter hose on my shop vac will it create more suction power?

Yes, in one way the suction would be higher, but there would now be an additional load on the motor. Also, it would have more suction, but less volume (air flow).

How do I get reverse suction with the electrolux epic 6000?

I have no idea just what reverse suction would be or how to get it from ANY vac. If you're looking at getting the blowing air from the vac instead of suction, then simply move the hose from the suction end to the exhaust end.

Loss of suction power & exhaust coming out of vents beneath exhaust port w/ barely/if any air pressure out of port itsef.

You should find your user manual, look up the phone number for Shop Vac's customer service and call them. They will be very helpful and with the unit being no older than that, it should still be in warranty. They will probably have you send it back and will possibly just send you a whole new unit.

Lg 300B no suction through hose

If you have a loss of suction overall, that generally means one of two things, either you have a clog somewhere near the motor or the motor is fried and will never turn fast enough to make proper vac.

No suction

Use the guide at to find the issue and solution. Most likely you need to test it without any filter and be sure the bottom of the unit is attached :) To get access to the motors you need to unbolt the very top sides.

Model UH60010, Series X12.0, Mfg code K09A. While attempting to use the hose and the extensions to clean shelves, my wife reported no suction. I removed the brush roller and the plastic piece just below...

There are six different reasons a vacuum can lose suction, a plugged vacuum hose, bad motor, full vacuum bag, or cracked or damage hoses. Purchasing a vacuum cleaner can be a costly expense while repairing the suction on the unit can be virtually free. Most suction loss problems on a vacuum can be easily fixed or remedied with common house hold tools and very little technical expertise.
If your vacuum cleaner losses suction, the first and easiest solution is to check the bag. If the vacuum cleaner bag is full suction will be greatly reduced and the unit will become ineffective. A vacuum cleaner works by passing air through the bag fibers leaving dirt and debris behind inside the bag. If the refuse bag becomes full, airflow is restricted, limiting the amount of air passing through the vacuum bag resulting in loss of suction. When replacing the vacuum bag always consult your owners manual to insure that the vacuum bag seals with the vacuum inlet hose. If your vacuum cleaner bag is not tightly sealed to the vacuum inlet hose you will decrease the air flow through the bag resulting in loss of suction.
The second and sometimes most common reason for loss of suction on a vacuum cleaner is a plugged vacuum hose. If the hose becomes plugged, air flow will become restricted. To unplug a vacuum hose detach it from the machine and inspect the inside. If there is a restriction in the hose, remove it with your fingers and replace the hose onto the unit. If the hose is long and the debris is hard to get too, a broom handle or other long object can be passed through the hose to dislodge the debris. Most vacuum cleaners contain more that one suction hose, so make sure to check each one by process of elimination. Another area that can become easily plugged on a vacuum cleaner is under the lower base of the unit by the roller brush. Large debris can get caught in this area and restrict air flow to the hose.
If your vacuum refuse bag is not full and the suction hoses are not plugged the next thing to check is the condition of the hoses. Many hoses are made from plastic which can easily tear or crack. If your vacuum cleaner shows signs of wear or are cracked they need to be replaced. Even the smallest hole in a vacuum hose can leak enough air to greatly diminish the suction potential of your unit. Replace your vacuum cleaner parts with OEM parts from the original manufacturer to ensure the tightest fit.
Most vacuum cleaners contain filters. Filters are used as a last line of defense to remove dust and smaller debris particles before the air is recycled back into the environment. If vacuum cleaner filters become dirty or plugged they also can decrease the amount of air traveling through the unit. Some filters can be easily rinsed with water whereas others need to be replaced. It is important to check your owners manual before rinsing a vacuum filter.
The last and probably least common problem for a vacuum cleaner to loose suction is a bad or failing vacuum motor. Over time vacuum motors lose power due to worn carbon brushes or long term damage. A vacuum cleaners worst enemy is moisture. If water or moisture is sucked into the vacuum motor it will greatly diminish the amount of suction the unit has. Replacing a vac motor can be a costly and time consuming ordeal. In some cases, replacing a vacuum motor can outweigh the cost of buying a new vacuum. Vacuum suction is measured in water lift which can easily be measured by using a water lift gauge. If the water lift measured in inches, falls below half the original water lift specifications for the unit, it is time to replace your motor. Most vacuum cleaner repair shops carry this type of equipment and can easily tell you if it is time for a new vac motor.

Shuts off after a couple minutes of use

Sounds like it is stopped up. The vac gets overheated and the thermal switch does its job. Check suction from the hose and see what you get. If good then check the brush housing for a clog.

Attachment hose has no suction

Sometimes when you take them apart and
reassemble the vac (the plastic slide doesn't
make full contact with the lever,or it isn;t on
the lever at all) that switches
from the floor to the attachment. IF Tthere
are no clogs in the duct then that the
most likely problem
