How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
1. The dirt canister may need emptied or the bag/filter may need to be replaced – follow the instructions in your Owner`s Manual based on your power unit type. 2. The hose may be clogged.
The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
What`s happening with your vacuum cleaner is that a clog has built up and debris being agitated by the roller is spitting out or stirring up dust without sucking it in.
The base of the box has wheels and brushes, connected by a belt or gears or rollers. There is also a container for dirt. The arrangement is such that, when pushed along a floor, the rollers/wheels turn and force the brushes to rotate. The brushes sweep dirt and dust from the floor into the container.
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.
Positive displacement vacuum pumps operate by expanding and contracting a sealed chamber where the flow of fluid is controlled by one-way valves. The vacuum generation process starts by expanding a sealed chamber generating a vacuum. This vacuum draws the fluid into the chamber through an intake valve.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
Check both ends of the tube for any debris that may clog the machine. Make sure to empty dirt bin and clean the filters if they are dirty. If you experience no suction when using a tool, remove the tool and check each opening for clogging.
Replace the Brush Belt
If the vacuum is still hard to push, tilt it back far enough that you can inspect the moving brush while the vacuum is running. Be careful to avoid getting too close to the moving parts. If you see that the brush is not turning, that means you will need to replace the brush belt.
Vacuum means the absence of all matter including air. As there is no air in the vacuum, air pressure will be zero.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
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.
One of the most common reasons for a vacuum that`s hard to push is using the incorrect suction setting. Most people want to use the maximum suction setting all the time, when in some cases this isn`t necessary.
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.
The exhaust filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner`s manual for cleaning instructions.
Vacuum Is Clogged Of Debris/Spitting out Dust
The Dirt Devil Gator is clogged of debris or spitting out previously picked up dirt.
Some of the best vacuum cleaners come with a standard attachment (like an extension wand or upholstery tool) that will help you get to those hard-to-reach spots or smaller nooks where crumbs and debris get trapped.
First check the airflow valve located under the handle. Sliding this open may make it easier to push your vacuum. It could also be that your suction is set too high. To fix, use the suction controls on the canister to adjust the suction settings.
If this is normal air pressure at sea level, then the force is around 15 lbs for every square inch of the surface area of the container. If you`re deep underwater – then it could be tons per square inch.
Any negative pressure significantly below standard atmospheric pressure (760 Torr/mmHg, 29.9 inHg or 14.7 PSI) is considered a vacuum.
features a psi of 0, that means that the ducting in question is at 0% vacuum pressure (otherwise known as “standard atmosphere”). -14.7 psi, on the other hand, is absolute full vacuum pressure, meaning that the duct hose is as empty as can ever be possible.
The Main Parts Of A Vacuum Pump
We have the electrical motor on the back, the compressor at the front, a handle on top and a support base on the bottom. We then have an inlet which connects to the system to remove the air from the system and we also have the exhaust to disperse this to atmosphere.
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.

The suction is good, but it can’t pick up most of the stuff on the floor. The hand held hose works very well, but it doesn’t even pick up little fuzzies reliably when I push it along. And, the suction is too hard I think because it used to push easily and now I have to push really hard, even on flat carpet.
ANSWER : Check entire length of hose, including the piece in the power head, for clogs. Simply drop a marble in one end and allow it to roll out the other. If it doesn’t, then the hose is clogged somewhere.

When pushing foreward the vacuum is hard to push and if pushed on to hard it will turn over on itself.
ANSWER : My dyson dc17 animal had become nearly impossible to push on carpets.
sure enough i found that my roller was warn down to nubs (vacuum is probably 8 years old, and gets used nearly every day)
I replaced the roller and WOW! it feels like its self propelled now. HUGE DIFFERENCE.
thanks for the help!!

Dyson suddenly hard to push on carpet
ANSWER : I know this sounds silly, but it works. Turn it over and wipe all the black residue off the bottom of it (off the plastic on the bottom that rubs on the carpet as you push and pull it). I thought my husband was out of his mind when he told me that was the solution, but it really works.

Hard to push
ANSWER : Since I could not find help on the internet, and you guys only wanted to charge a fee for information (which is fine, by the way, although I declined) I called the toll-free help line I found on the Dyson web site. They walked me through a series of steps to find the problem. Ultimately, I needed to open the cyclone device and clean out the very center of it. I had never read the instruction manual and did not know that I was supposed to clean the center of the cyclone every month. My was very compacted with dust. It was very easy to clean, once I knew to do it. They also had me wash my hepa filter with water and lay it out to dry. I recommend calling the Dyson help line. They were great.

While using my mop yesterday, it stopped letting steam come out. Tonight I plugged it up again and you could hear it trying to steam. I push the button in to release the square frame and it pushed out a burst of steam and pushed the head off. Put it back together and it still will not let steam out. No matter how much water is in it.
ANSWER :
.Hi,
Here is a tip that I wrote about the Euro-Pro Shark Steam Mop and why it maynot be getting steam to the head…

I have a self propelled Royal Dirt Devil vacuum model number 087900 and it goes backward fine but forward has to be pushed so hard it’s impossible. Is this a switch? Do you know about how much the part would cost and can it be done by a beginner. We fix a lot of things ourselves but we aren’t mechanics by no means. We put a brand new belt on it. I don’t think it can be put on backwards and brush turns fine. Where is the switch? Use layman’s terms.
ANSWER : You might try a new belt and/or brush roll. The brush roll is what helps pull a vacuum forward, the power drive helps, but if the brush isn’t turning like it should, then it will hinder forward motion. The belt may look ok, but they stretch to the point that under load they won’t drive the brush roll.
