How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

The suction capacity indicates how powerful the vacuum cleaner is, and the air volume indicates how much air the vacuum cleaner is able to move. The suction power adds up the suction capacity and the air volume and indicates how much power the vacuum cleaner has.
A hard vacuum denotes a more complete vacuum is created in the tube manufacturing process. Hard vacuum tubes – like the 6L6 and 6550 – have a higher saturation threshold and therefore distort less easily then soft vacuum tubes.
Check the Rotator Brush and Wheels

Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.

The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH2O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m3/h or in l/s.
Any negative pressure significantly below standard atmospheric pressure (760 Torr/mmHg, 29.9 inHg or 14.7 PSI) is considered a vacuum.
Vacuum has no “strength”. The only reason why a vacuum vessel on Earth must be strong is to resist the crushing pressure of Earth`s atmosphere. Also, High vacuum systems do not “suck” matter out of the vacuum vessel.
One method is as “Hg gauge (“HgV), where the scale starts at 0” Hg (atmospheric pressure) and goes up to 29.92″ Hg, which is perfect vacuum.
In rough- and medium vacuum most gas molecules are within the volume of the vacuum chamber, whereas in ultra-high vacuum (UHV) and extreme high vacuum (XHV) most of the remaining molecules will be on or in the chamber walls respectively.
In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change.
The pressure exerted by air per unit area is called as atmospheric pressure. Vacuum means the absence of all matter including air. As there is no air in the vacuum, air pressure will be zero.
Because the maximum theoretical vacuum at sea level is 29.92 in. -Hg, actual pump capabilities are based on and compared to this theoretical value. Depending on pump design, the vacuum limit ranges from 28 to 29.5 in. -Hg or about 93% or 98% of the maximum theoretical value.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

Kenmore Progressive canister model 116.27514700
Problem: Vacuum motor won’t turn on. The power head operates, but nothing from the vacuum. Have checked all areas of airflow: hose, bag, motor filter and hepa filter. All are fine. Have checked and rechecked all electrical connections, all seem to be in working order. Vacuum hasn’t run for a week or so, so it’s not the thermal protector, unless it’s defective. Vacuum was running fine last week. Didn’t stop operating when using. Went to v
ANSWER : Hello! The culprit is the PCB Assembly;
Part # KC86WBZR3000…Cost is $6.99. I would remove and inspect for burnt components, or broken wires…Then clean connections both male/female using an eraser, toothbrush and alcohol…Using a bright light and a magnifying glass inspect solder joints for “bridges” or cold joints. If you detect a problem during this procedure (to the exclusion of burnt components) fix, reassemble, and test. If problem still persist: Order a new part.

if you have any question feel free to send a comment.

Vacuum is hard and heavy while operating
ANSWER : Make sure that you don’t have the brush set too low. Check the wheels and brush and make sure that they haven’t picked-up excessive hair or a long string and are binding.

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.

Unbeknownst to me, someone took the bag out of my Kenmore Progressive vacuum and failed to replace it. I have been vacuuming without a bag for months, and today the vacuum stopped sucking. When I opened up the front to replace the bag, tons of dirt and dust came pouring out. I thoroughly cleaned the vacuum, put in a new bag, but still no sucking power. Just dust coming from the rear vents where one of the filters is. Is the vacuum ruined, or is it a simple solution of buying a new filter?
ANSWER : Sounds like you need to buy a new motor. All that grit and dust will ruin a motor and I’m surprised it lasted as long as it did.
.This is where a vacuum that won’t run without a bag would have been nice. (Aerus for one)

I have a Kirby G4 Vacuum Cleaner – MOdel G4 D. I have never had any problems or repairs done to it in the past ten plus years that I’ve had it. This is an upright vacuum. I was vacuuming the carpet floor and was not having any trouble at all. I switched the vacuum off and moved it into a different room. When I tried to turn on the vacuum, it would not turn on. I checked with different outlets, used both front attachment and hose attachment. Checked the front part of the motor/ spiral case. This

Electrolux Epic 6500SR Full Bag sensor working, Does not Reset properly
ANSWER : The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.
