Tip & How-To about Vacuums

Vacuum cleaners: Loss of Suction

A common complaint about vacuum cleaners, regardless of the brand, is loss of suction. The motor runs fine, there seems to be plenty of power, and even some suction, but the vacuum just won't pick up even the lightest of items. There are some very simple checks and fixes to this problem most of the time.
The primary causes are: clogged hose, full bag, leaky hose.
Clogged hose: this is probably the most common cause, and will result in a damaged motor if not cleared.
Check: Remove hose from vacuum and wands. Holding one end, drop a marble or small ball into the opening and allow to roll through. If it doesn't come through the end, then the hose is clogged.
Solution: If you have a canister vacuum with an exhaust port, try connecting the hose to this and turning machine on. If the clog isn't too bad, this may clear it. If not, more extreme measures may be needed.
Never attempt to clear a clog with a coat hanger or similar length of wire, as this could easily puncture the house. Do not use water or high air pressure gun to clear hose.
Full bag: Check bag. Change if necessary. If it seems the bag should hold a little more, well, it's not worth replacing a motor, or the vacuum, trying to find out. Bag pores are easily clogged if the machine is used for cleaning construction areas where sheet rock dust is abundant. Ensure you’re using genuine bags for your machine.
Leaky hose: Over time, hoses suffer from normal wear and tear, and often abuse, resulting in cracks and holes, often too small to notice. Hoses need to be replaced at this time, and this generally results in a dramatic increase in "suction". There simply is no fix for a leaky hose.
Solution: Always store the hose properly to avoid kinking, crimping, smashing, etc. Avoid stepping on the hose, or leaving in an area where it may get stepped on , driven over, or smashed. Avoid pulling the vacuum by the hose, or otherwise stretching/stressing the hose.

Why has the vacuum cleaner lost power?


If by power loss you mean loss of suction power then I would check and either clean or replace ALL of the filters. Check and clean the rotating brushes and make sure all of the tubes are clear. Almost all suction loss is down to some form of blockage to the air passing through the cleaner and unless the air can pass freely through and exhaust properly, it will not pick up efficiently.

my 5200 hoover spin scrub all of a sudden stopped sucking in mid clean.i took the front clear cowling off and checked for blockage but couldnt see anything.there is nothing to these thiings,they are disposable it seems lol


Most likely your vent for the suction container is plugged or the suction hose can of or is broken at the connection to the tank nozzle (very common on these. Clean the machine thoroughly, and check that all hoses are tight and connected.

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 where the hose opening is located and saw a "flapper" door that was closed and had some debris sort of jamming it. I removed the debris, but the door requires extreme pressure to open to permit the dirt, etc to moved up thru the opening , through the hose, etc. I thught maybe that somehow tghe flapper door would open when operation began, but no dice. It remains closed after I assembled it again and tried to use the hose--no suction and the flapper door is closed.???????????


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.

How to for Belt replacement and solution to suction loss


You say it lost its suction, then you also say this is plenty of suction power, seems you cant figure out the prob. Try cleaning the fan on the suction blower. The blades can get chocked with dust which will give you a reduced suction.
