How to Identify and Fix Common Vacuum Problems ?

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

Vacuum cleaners come with various foam or mesh filters. These might get clogged over time if not cleaned or replaced properly. This will cause your vacuum to lose suction.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
On average, According to Consumer Reports, vacuum cleaners last a median of eight years. But the lifespan varies wildly by not only brand but your own personal use. This should be expected.
How Many Watts Does a Vacuum Cleaner Use? A vacuum cleaner gets power from a regular electrical socket, with the average upright design requiring between 450 and 3000 watts. However, the most often used versions use around 1400 watts, equivalent to approximately 1.4 kilowatt-hours (kWh) of electricity each hour.
Using the upper limit of the cosmological constant, the vacuum energy of free space has been estimated to be 109 joules (102 ergs), or ~5 GeV per cubic meter.
A major driver of vacuum cleaner power usage is the motor. Commonly available vacuum models have motors that use between 500 and 3,000 watts of energy, with the average machine using about 1,400 watts.
Suction Power

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.

Vacuum cleaners work because of Bernoulli`s Principle, which states that as the speed of air increases, the pressure decreases. Air will always flow from a high-pressure area to a low-pressure area, to try to balance out the pressure.
To attain a state of vacuum, a space must be empty, i.e. devoid of all gaseous material. The consequence of this is that the pressure in this space is very low, as it contains no or only a small number of particles, which exert a force on an area as a result of their impact against the walls.
Over time and extended use, a very fine layer of particles will start to line the inside of a vacuum bag, remaining in place even after the bag is emptied. This means that the bag will lose the proper airflow required to let the incoming air escape. As the airflow is restricted, the suction dies down too.
A traditional, standard vacuum uses around 1.4kWh of power per hour; the humble robot charges on about 60-90 watts (over three hours), with one charge fuelling roughly an hour of cleaning. It`s a no brainer! However, it`s just not as simple as all that.
Pushing your vacuum cleaner around every room in the house requires some serious calories. Vacuuming for 30 minutes zaps 99 calories if you`re 120 pounds, 124 calories if you`re 150 pounds, and 166 calories if you`re 200 pounds. Do dance moves or lunges while you push to pump up the burn.
Washing machines, dishwashers and tumble dryers account for 14% of a typical energy bill, taking the top spot in our list. The power needed to heat the water that they use pushes up consumption, making them energy-hungry household appliances.
Perfect vacuum is an ideal state of no particles at all. It cannot be achieved in a laboratory, although there may be small volumes which, for a brief moment, happen to have no particles of matter in them.
Energy ratings of vacuum cleaners tend to be between A++ to D. As you go up in this scale, vacuum cleaners become a little costlier to purchase, but cheaper to run and better for the environment.
They need to leap because the vacuum is a perfect insulator and so there is no medium in which they can flow (like through a metal conductor) so they must acquire all of the energy necessary to cover the distance before they can escape the cathode.
In conclusion, we can say that an electric field can exist in a vacuum.
Vacuum System Failures:

Occurs when the vacuum pump fails or when both intakes are blocked.

Second, can you vacuum too much? Believe it or not the answer is no. Now, if you vacuumed continually 24 hours a day, yes, that would be too much. Vacuuming every day, or even a few times a day, is not going to create any long term problems.
Overheating usually occurs because the dust bag has not been emptied, filter has not been cleaned or there is a blockage in the floor tool, wand or bent hand piece. If your vacuum shuts down unexpectedly, make sure you turn the vacuum off and unplug it from the wall socket.
The basic formula F=PxA is used to calculate the force of the suction cup with: F is holding force (or the vacuum force of the suction cup) P is pressure.
Vacuum is primarily measured by its absolute pressure. At room temperature and normal atmospheric pressure, one cubic foot (0.03 cubic m) of air contains approximately 7×1023 molecules moving in random directions and at speeds of around 1,000 miles per hour.
In general, a vacuum is created by starting with air at atmospheric pressure within a chamber of some sort.

Power head attachment works great when plugged into the hose part of the vacuum. The problem is when I attach it to the tube for normal use there is no power. I have checked all the connections and switched the power switch on and off still no power from tube to power head.
Is there anything else I can try? Model Callisto
ANSWER : Try having someone turn the machine on and off while you pull the cord in and out with the cord more angled towards the on/off switch. Sometimes these models have a break in the cord rewind and will not put the power through to the motor.

Keep in mind this is repairable, and if the unit is less than 5 years old it should still be under warranty.

Good luck .

The power brush floor rug attachment on my Eureka 6997 A Oxygen Canister Vacuum goes on an off as I use it. I replaced the The power cord from the handle has 2 plug in connections:
1 at the handle / upper wand
1 at the lower wand top of the power brush attachment

I replaced the entire wand assembly and it worked great for a year or so and now it’s doing the same thing again. I was told to keep the power switch on the handle set to off when connecting the power brush attachment or it will bu

ANSWER : This is from the prongs not making a good connection causing an arch inside the plugg causing what looks like rust on the plugg. I would try snugging up the connection by squeezing the female section to get a better connection on the prongs when it is plugged in together.

I have an Easy-Flo central vac unit. The handle on the electric hose has a switch on the handle. With the switch on ”O” in the center, it’s off. On the left, is the ”I” position. The vacuum runs but the power brush doesn’t. On the right is the ”II” position. The switch won’t flip that way. It feels stuck. It feels as if there is something underneath of it that won’t let it push that direction. I have the switch out of the handle, but I can’t seem to get the actual black casing around the
ANSWER : Switches are not usually designed to be dissembled.
I would strongly suggest that you dont take the switch apart. you are better off getting a new one. then if you feel like it you can take the old switch apart and if it dosnt work you still have a new switch. if you decide to dissemble the old switch be vary careful there are very small parts in there that will fall out. and most of the time the casing will crack when you pry it apart.

Good luck

Electrolux Epic 6500 SR …no power to power nozzle. I think it is the switch in the handle because if I use my friend’s hose/handle (same model), my power nozzle works fine when I turn on the switch. If you think it is the switch, can I get a part for it?
ANSWER : That’s about the best one to narrow down a problem, however, there could also be a break in your hose wiring. Switches, hoses, and hose handle assemblies are all available at your local Aerus Electrolux store. Simply take your entire machine in so they can check it to be sure what the problem is.

Hooked everything up per directions. I plugged it in to the closest electrical outlet and nothing happened. The lights did not light up, the connected wall control and sensors leds do not light up. It appears the unit doesn’t have power. The electrical outlet socket is fine as everything else I plug into it works fine. I have tried every other electrical outlet available. The unit won’t power on from any outlet, and all of those outlets run other things, like power tools an refrigerators
ANSWER : Dear Davehibshman,

Firstly; dismantle the plug and replace the fuse with the same rating as the one you have just taken out. Replace the plug cover, put the plug into the socket and try again. If this doesnt work, there may be a problem with the internal fuse (if one is fitted). Two choices here, either refer this unit to a qualified service personnel/ the place where you got it from, or do the job yourself (which will save you a whole bunch of cash). In your circumstances, I would take it back to the place you got it and ask them to put the fault right, or replace the unit completely; if it is past its warranty or guarantee time, then get back to me with a make and model number of the unit, and I will give you step-by-step instructions on how to solve this.

Yours sincerely

We have a dyson dc 07 animal the machine was working fine then switched off after returning to the machine minutes later it wouldnt switch on, i removed on off switch cover and used a short piece of wire across the brown wires flicked the wall switch and it worked, aha i thought faulty switch aquired a new one to no avail and now even the short piece of wire trick doesnt work, has the motor died do you think, it wasnt over heating or making strange noises prior to refusing to work
ANSWER : It could be the motor. I’m having to replace the brushes on my DC 05. It appears that you can only get brushes for the YDK motors in the DYSON, not the Panasonic motor. Which might be saying something about the YDK motors. What happens is that the carbon brushes wear down which is normal. However, the contact wire from the brush to its connector is set so that when the brush wears down, the wire is short enough to stop the spring etc from damaging the commutator. The end result is that you get an intermittent operation of the motor before it finally dies.
.I believe all the DYSONs come with the option of both motors and you cannot really tell which motor you have until you take the thing to bits. You also cannot change motors without changing various other parts on the hoover. On my DC 05 the writing on the YDK motor tells you which one it is.
.This website www. ,select the DC 05 option and scroll down tells you how to take the thing to bits. A search on google etc for your DC 07 may give similar results. Best of luck!
