How to Identify and Fix Common Vacuum Problems ?

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

Sometimes your vacuum pulsates on and off or keeps dying when using the extra powerful `Max Mode`, which can be related to the charge of your battery. Try turning this function off by pressing the Max button on your vacuum.
It`s possible there`s a power consumption issue, with there just not being enough residual charge to run the machine. A new battery should fix this. My other thought is that it`s overheating. If too much power is pushed through the motor, which MAX power does, it could stop after a few seconds if it become hot.
One of the first things to do when your Dyson vacuum cleaner keeps starting and stopping is to empty the bin. It may be full, or the machine may simply perceive it as too full to continue working. Dyson vacuum cleaners require constant airflow through them to work, and a full bin can stop this from happening.
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 vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
Check the LED light to determine the battery level. A solid blue light indicates that the machine is in normal operating mode. A flashing blue light indicates that there is no power, and the battery needs to be charged for a minimum of 3.5 hours.
There are many reasons why your Dyson Airwrap may be overheating and shutting off. This could include excessive use, a clogged filter, or blocked air vents. Fixing this issue is relatively straightforward. First, make sure to give your device a break in between uses.
Most cases of a jammed or stuck brush bar are quick and easy to fix, simply pulling the debris gently from the brush bar. Alternatively, if you need to clear a problematic blockage, you can take the brush bar out of the housing easily, for quick maintenance.
If there is a strong burning smell coming from the motor area of your Dyson DC14 or DC07 then it is most likely that your motor has burnt out.
All batteries, even Dyson`s high-end lithium ion batteries fail given enough time, and the blinking red light problem is an indication that your battery has failed. The battery cannot be fixed. It has to be disposed of and replaced.
When your Dyson no longer powers on even after charging the most likely cause is a damaged battery. This means the battery will no longer hold a charge and will need to be replaced. Once a new battery is purchased you can learn how to replace it by visiting our battery replacement page here.
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.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
Check For Clogs or Blocks In The Vacuum

Check the hoses, the filters, and throughout the vacuum, and clean out any blockages or clogs. Vacuums will likely also have a recommended cooldown time to ensure that the vacuum won`t overheat. You will need to wait for that time before you turn the vacuum back on.

Check for a plugged hose:

Plugged vacuum hoses are sometimes the reason for a loss in suction. Hoses can get clogged with hair, dust bunnies, string, or anything else that can`t pass through the other end of the hose. Airways inside the machine should be looked at as well. Wherever there is an air passage, check it.

However, in the MAX mode, when the device utilizes more current, it will give about 2 minutes of usage. After buying the new battery, it needs to be charged for about 3.5 hours, and 40 minutes thereafter. Check the link to know more about Dyson battery life.
It can take up to four hours to fully charge your battery. Your battery has been designed to be left on charge. Your machine won`t operate or charge if the ambient temperature is below 5°C (41°F).
The most common cause of no power is the machine overheating and cutting out. In this case once the vacuum cleaner loses power leave it for at least half an hour and then try turning it back on again. If it comes back on again after an hour then clean your filters and check for blockages.
Summary. Dyson batteries should last around 2-6 years before needing to be replaced. This wide range reflects the fact that how you care for and maintain the battery will affect how long it lasts. If you want your vacuum`s battery to last longer, make sure it`s stored at room temperature.
3 solid blue lights indicates that the machine is fully charged. If the machine is cutting out/pulsating, this will indicate a blockage.
We recommend replacing your air purifier filter every 12 months. That`s because over time, filters can get clogged with pollutants, and even let unpleasant odors back into the room.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
Problems can occur when overused or clogged filters cause the vacuum motor to overheat. This not only shortens the motor life but causes a loss of suction. In some cases, total motor burn out can occur.

I have a dyson dc05 absolute turbobrush vacuum. turned it on and it slowly died in seconds. then tried to turn on again and only came on sporatically for a moment.
Is it the on/off switch or motor?
ANSWER : Hi there VacuumGuru for vacuumspot.com.au here. It is likely to be the motor for that model but it is easy to test. I will answer this with the assumption that a person wouldn’t try to repair something they are not qualified to do. All you have to do is disconnect the wires off your switch and join them together (with power cord disconnected from socket obviously). Then plug you cord in again. If it still plays up then it is your motor if its fine replace your switch. We stock switches and the motor for that machine if you live in australia by the way.
.Hope this helps.

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.

Bad Motor I have purchased two of the Kenmore direct drive beltless systems with Progressive systems. The first died after a year, the vacuum motor start making a grinding noies. I pulled the side HEPA filter and could see a fine coating of graphite like dust. Took it to a vacuum repair shop. They said the brushes were going and thus the motor was shot. I liked the vacuum and bought a second, 1 year later the motor is making a slight noise that and removing the HEPA filter I find a slight metall
ANSWER : That dust is from the carbon brushes on the motor. You may need to check them, and also clean out the motor compartment. A slight noise could be a motor bearing starting to go. Does the smell like rubber or electrical. If rubber, then the belt has stretched and needs to replaced. If electrical, then something is causing the motor to run hot, like a clogged filter, or it could be a motor going bad.

Infinity Vaccum by Shark, model number NV31COS, will not start. The vacuum was running just fine until it grabbed the edge of a curtain. Turned it off to release the suction. Turned it back on and was working fine. About a minute later the vacuum was making an odd noise. Every 2 seconds or so it would “heave” (lack of a better word) then go away, then come back and so on. Turned the vacuum off and checked for blockage, none that could be seen or felt, and now the vacuum won’t turn. Any suggestio
ANSWER : Carpet brush won’t turn when vac on

The breaker on the vacuum trips after about 3 seconds on. The canister was extremely full and started to smell like burnt wood, we fully cleaned out the unit. Now when the vacuum is turned on, the motor sounds weak, and then turns off in a matter of seconds,and we have to reset the breaker on the vacuum to get it to start again for another few seconds.
ANSWER : This sounds indicative of a worn set of carbon brushes on a dieing motor for a central vac. the armature is ,likely damaged causing teh breaker to blow. Please post back with more details as to make and model. Do not atempt to run the vac

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer.

There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth.

The beater bar motor turn-on mechan

ANSWER : Good day!

Normally when the motor is easily moved back and forth means that it have a proper lubrication,proper alignment and no clogs.

When the motor and the belt is OK the problem could be on electrical wiring and switch.

If found electrical switch burned out you need to replaced it because when the switch is burn the contact of that switch is open even you turn it ON.that’s why the motor is not function because the voltage is not pass through the circuit because of open switch.You need to replaced it.
And check some fuses if any and other burned electrical wire.Replaced it also.

Thank you and don’t forget to rate my answer.

I have a dyson canniter stow away vacuum. i’ve had it for 2 years and it just started having a problem. when i turn it on the motor starts just fine but the vacuum head does not turn on. Yet when i push it forward it trys to start and turns on for a second and turn off – almost like the connector isn’t connecting the hose to the head very well anymore.
ANSWER : Hi, After reading you’re problem, the symptom’s are just like you said. Its just a matter of checking the connections. The connection where it plugs into the head it self. When you push forward the forward motion and down pressure makes the connection for a few seconds. Anywhere you have a power connection double check it to see if it is loose. I wouldn’t think it is a serious problem, just a matter of looking it over very good. You should have no problem in finding the solution.When you first turn it on is when the head should also turn on, so, that’s where I would check first where the hose connects to the motor. Move the hose and head around to see if it trys to start and see if you can locate the problem. Keep me posted on what you have found and we can go from there.
