How to Identify and Fix Common Vacuum Problems ?

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

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 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.

If your Shark ION Robot R75 vacuum stops moving unexpectedly after a few minutes of normal movement, it may simply have low battery power. Check that the device is powered on and that the battery has a significant charge.
Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
Most owners believe that running their robot vacuums four times per week is sufficient to keep the floors dust-free. However, if you have children or pets, you should use your robot vacuum more frequently. Daily vacuuming is recommended if you suffer from seasonal allergies.
Keep your robot plugged in and charging on the Home Base® or Clean Base™ when not in use. If your robot will not be used for more than a few weeks, we recommend placing the robot in ship mode. and storing it in a cool, dry place.
Why does my Shark vacuum keep stopping? For Shark robotic models, odd sweeping or sudden stops can often be a result of dirty vacuum sensors. These sensors can often be found on the bottom and sides of the vacuum. Hitting them with a soft cloth should be enough to remove any excess dirt.
If the filter bag or canister is too full, it cannot pick up any additional particles and will simply jam or the motor will overheat and shut down. So, when you suspect your unit is about 75 per cent full, empty it!
Signs of Vacuum Pump Leaks

Oil from the exhaust port running down the pump. Rumbling sounds coming from the pump. Repeated failure to reach maximum pressure for tasks. Mist or smoke coming from the exhaust section of the pump.

The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
Vacuuming every day, or even a few times a day, is not going to create any long term problems. `But,` you might be thinking, `doesn`t the brushes spinning over the carpet on a beater bar wear it out? ` Sure, but a very small amount.
Manifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engine`s intake manifold and Earth`s atmosphere. Manifold vacuum is an effect of a piston`s movement on the induction stroke and the choked flow through a throttle in the intake manifold of an engine.
The maximum vacuum that can be achieved in locations above sea level will be less than 29.92-in. -Hg. The force will be limited by the ambient atmospheric pressure. Vacuum pumps have maximum vacuum ratings based on sea level conditions and must be re-rated for operation at higher elevations.
In a vacuum chamber, the pressure can be extremely low. So low, in fact, that water can actually boil at room temperature. So, if you put some water in a high-vacuum chamber you will see it boil.
There are varying degrees of quality and value when it comes to vacuums; if you paid a lot for the appliance, repairs are likely worth it, but we recommend that you don`t spend more than half of the original price for any repairs.
For nearly 20 years, Roombas have been working hard to make our homes tidy. Made by iRobot, these robotic vacuum cleaners use sensors to detect walls and items in a room, becoming smarter the more frequently they clean.
Traditional vacuums generally offer more power, too, which translates into more suction. While robot vacuums can easily handle low-pile area rugs and runners, traditional vacuums are better suited for homes with wall-to-wall plush carpeting and much larger areas.
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.
It`s important to fully charge the machine before using it for the first time, and after every clean. This helps to improve the algorithm`s accuracy. The battery is designed to be left on charge permanently, and this will ensure that the vacuum is fully charged when it`s next used.
Clean the Sensors

The robot vacuum may beep and shut off if these sensors are clogged or dirty. Clean the sensors with a soft cloth to resolve this problem.

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.

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.

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.

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

Suction Problem I was vacuuming and stopped to empty the cannister. When I started vacuuming again – the suction wasn’t working properly. The vacuum was just pushing stuff around the floor. I cleaned the hair out the brush on the bottom and it still isn’t working. It was working fine before I emptied the tube 🙁 I can’t figure out what happened.Help!
ANSWER : Greetings from GoVacuum,
.
.I believe what may have happened is that your vacuum cleaner belt has either broken, or been stretched so far that ithe brushes are no longer spinning fast enough.
.
.Here’s what you should do to diagnose this problem.
.
.1. Take the suction hose out of the back of the vacuum (assuming that your vacuum has on-board tools), and see if you have any suction coming from the hose. If you do, this indicates your belt is bad.
.
.2. If you don’t have suction coming from the hose, then it may be something as simple as replacing the filters, to a clog in the vacuum, or to your motor going bad.
.
.In my professional opinion though I would say from what you stated that the belt is mostly likely going to be your issue. If you can provide me the model number of your vacuum cleaner, I can walk you through step by step on ow to replace the belt.
.
.I have posted a short YouTube video on a vacuum belt change, this is not for all vacuums, but it will give you some idea of how to change a belt;

Won’t start. My son was using the vacuum & Didn’t change the bag. The vacuum was making the full bag smell, but the light was’t on & it didn’t stop. I stopped him, changed the bag, checked the filter, closed the compartments & turned on the vacuum. Nothing happened. I checked to be sure that it was plugged in, that wasn’t the problem. I’ve let the vacuum “rest” for several days, It still won’t start. Any suggestions?
ANSWER : There is a reset button at the back of the powerhead. The user manual can be downloaded from the electrolux website, although I didn’t find it very useful. There was some info on how to change the powerhead drive belt.

I have a panasonic mc-ul975 vacuum that works great when working properly. the airflow through the canister seems to stops once the aero blast technology is done running which causes the vacuum to not function as it should (does not have as much suction and the hose/tool accessories do not work at all). if air is continually running through the canister everything seems fine. please help!
ANSWER : Hi there. In Panasonic vacuums2.gif, there is a thermostat protection on the motor. It will automatically shut off the motor if there is no airflow through the motor. This is typically caused by a clogged hose. Typically, if your dust container is that full, there could be backup in the hose. Or the dust container being too full could also or otherwise be the problem. Check your hose for blockage, let the machine cool off, it should start up again

Hoover Vacuum works, then stops in 3-5 mins. Works again in a couple of hours
ANSWER : More than likely there is an inline over current breaker that is bad or weak and needs to be replaced. This is for overcurent protection of the motor. It is fairly common for the protection circuit to go bad
