How to Identify and Fix Common Vacuum Problems ?

The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
Regardless of what type of vacuum cleaner is being used, all of these products have a motor to create the negative pressure, or suction, necessary to draw in the dust and debris.
The simplest place to start: empty your dirt container. Debris in the main cyclone passage will cut suction rapidly. If the container was really full, you should also check the filters because they can get loaded with dust if the Dirt container is too full. Test the vacuum, and see if the suction is back.
Suction is the air pressure differential between areas. Removing air from a space results in a pressure differential. Suction pressure is therefore limited by external air pressure. Even a perfect vacuum cannot suck with more pressure than is available in the surrounding environment.
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.
Polyethylene, polypropylene, teflon (FEP, PTFE, PFA) and PVC are examples of plastics which are not hydroscopic, while nylon, polycarbonate and acrylic are hydroscopic and should be avoided. For the best possible vacuum performance choose a plastic that is known to be low outgassing.
The maximum strength of vacuum at see level is about -15 psi. A related phenomenon that could help you better understand the limit of vacuum is: what is the loudest sinusoidal wave possible at see level? The answer turns out to be about 194 db.
A Dyson vacuum cleaner has a lifespan of around 10 years. This is considerably longer than most other vacuums. So, if you`re looking for a high-quality vacuum cleaner that will last you for a long time, a Dyson could be a good choice. However, remember that Dyson vacuums are expensive.
Suction is often defined as a force that causes a fluid or a mixture to be drawn into an interior space.
Tracheal suctioning is the most painful experience for ICU patients.
A vacuum can be created by removing air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli`s principle.
The best vacuum ever constructed on Earth was done at CERN at reported to achieve a density of about 1000 atoms per cubic centimeter. While this is astonishingly low, it is still over 2 million times more dense than interstellar space!
Ultimately, a perfect vacuum isn`t possible because quantum theory dictates that energy fluctuations known as `virtual particles` are constantly popping in and out of existence, even in `empty` space. Read more: How can something explode in the vacuum of space?
Outer space has very low density and pressure, and is the closest physical approximation of a perfect vacuum. But no vacuum is truly perfect, not even in interstellar space, where there are still a few hydrogen atoms per cubic meter.
It is therefore called a black hole, and its surface is called the “event horizon.” But contrary to popular myth, a black hole is not a cosmic vacuum cleaner. If our Sun was suddenly replaced with a black hole of the same mass, Earth`s orbit around the Sun would be unchanged.
For example, you can use a shop vac for water removal. A shop vacuum`s ability to suck up water saves you from using towels to soak up water on the floor or trying to squeegee it away. A shop vacuum even acts as a pump to remove larger quantities of water standing in a tub, shower, pool, aquarium, or garden pond.
The experts at Vacuums 360 will tell you. Liquids: Never vacuum up water or any other type of liquid with your vacuum cleaner. Mixing water with electricity is a recipe for disaster. At best, you would need vacuum cleaner repair; at worst, you could electrocute yourself.
Without air in your lungs, blood will stop sending oxygen to your brain. You`ll pass out after about 15 seconds. 90 seconds after exposure, you`ll die from asphyxiation. It`s also very cold in space.
Power. Most people should only require a 3.5 to 5 peak horsepower motor for their wet/dry vac. If it can suction up water and sawdust, you`re probably good to go.
However, the noise levels of vacuum cleaners fall between 75dB to 85dB. Thus, continuous exposure to such noise levels affect a user`s health while also being a sign and source of inefficiencies in the equipment.
Based on the latest survey results, Consumer Reports estimates that close to half of Dyson stick vacuums will develop problems or break within five years, compared with around a quarter of the stick vacuums from Shark, the most reliable brand for this type.
Hot environments speed up battery aging. So it`s best to avoid cleaning the car in hot weather or leaving your vacuum in rooms that experience direct sunlight for prolonged periods. The same goes for cold porches and garages in winter.
If your Dyson vacuum is producing whistling noises, it may be the result of air leaking out of the vacuum`s vents. Check for broken seals and incorrectly-fitted parts. Broken seals may need to be replaced.

No Suction I get great suction in the hose, but when I plug the hose back into the unit, there is no suction and the air flow indicator line goes completely red. I've changed the bag and filters. I took the small panel off the back and made sure there is no clog, and took the hose off to make sure there was no clog there. Still no suction. Please help.
ANSWER : I about to say that’s always a clog of some sort that causes that

No suction Just received my refurb. dyson animal bagless. Finally figured out how to get it all together, turned it on and there is no suction coming up thru the beater bar. The hair is just collecting around the bar and not going up into the canister. It appears all the suction is going thru the open red end of the attachment hose, which has a vented cover piece. Am I missing a piece or is there a switch to turn of the attachment suction?
ANSWER : So the red hose isn’t connected to a part on the vaccum so like it is connected to the connester but not to an opening just above the beater bar, this is the only idea i can supply you with. good luck, maybe i got lucky and helped you out.

Lost suction my DCO7 lost suction in the hose I started taking it apart and cleaning it and looking for clogs (probably more than I should have) and when I put it back together it has awesome suction in the hose but no suction in the base. It just pulls the pine needles up (christmas tree) but they never appear in the “bag” compartment and when I look they are just all gathered in a clump in the bottom by the brush.
ANSWER : Hi.
.
.Remove the sole plate turn the 3 plastic screws to unlock & lift off.
.
.Now remove the blockages that have accumilated from the oppening of short clear hose.
.Check you can turn brush roller & check belt.
.
.Now reassemble switch on pull handle back & look under machine is brush spinning ?
.
.If not check the knob on side of machine is in drive (D) position.

No suction I am getting no suction on my central vac at the vac. I do not believe that the piping is plugged up, the vacuum is not creating suction. What are the causes of no suction at the vacuum and how do I take the top half of the Nutone central vac off?
ANSWER : Use the guide at builtinvacuum.com/flowchrt.html 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.

Poor Suction Heya! So I just picked up a used Dyson, but when I vacuum with it, the suction is pretty weak and it spits all kinds of stuff out the back and into my feet. When I pull the hose I have good suction, but in regular mode it hardly picks up anything. The brushes are spinning, and it eventually will clean an area if I go over it again and again. Maybe a clog somewhere? Please tell me that Dysons have better suction than my $50 Dirt Devil! Thanks!
ANSWER : I recently bought a second hand Dyson DC07. Its suction was poor. I removed all the un-clipable pipe bits and to remove any blockage but it all looked clear. The Final Sponge and hepper filter did have a lot of dust in it and the rotating brush was full of hair but nothing bad.
.
.I eventual gave in to curiosity and removed the three screws in the top or the yellow removable dust collection tube and cyclone bit to see what was in there. The mechanism to release the flap at the bottom of the collection tube does not allow you to remove the lid completely but it does open far enough to get inside. I found the whole top section of the yellow plastic bit blocked by a big plug of compacted dust and a champagne cork. If you are willing to take the risk and have a torx 15 screwdriver handy it that part may be blocked. It did get a bit messy.
.
.If I was going to attempt the same procedure I’d remove the dust collection unit from the vacuum cleaner as I did before, but leave the clear tube attached and the emptying flap firmly closed to reduce the mess from the dust falling out the bottom while cleaning the top part.

Hi my dyson dc18 has great suction from wand but when you got to use the vac for floors little suction but wand still got suction even while vacuming floors is it suposed to stop suction from wand
ANSWER : My Dyson dc18 had the same symptoms. The wand worked well and the floor bar had no suction. After removing pieces & shoving my fingers into the machine (no blockage) I found the suction pipe rotates between two positions (floor and wand). It looks like a piece of plastic broke on the outside housing, so it no longer rotates positions when the wheels are raised or lowered. My son found we can move the suction by sliding a finger into the mechanism behind the wheel cover, and rotating the plastic piece clock-wise or counter clock-wise until it locks into position. It’s a big pain but it works for now. I wish I could find a replacement piece online. Patty
