Your Filter Needs to Be Upgraded

Some of the best options include HEPA filters and reusable dry filters. If you don`t use a container or dust bag already, consider adding it to your vacuum to keep things neat and prolong your filter`s life.

Why is the vacuum is blowing dusty air out of the back? Simple: the bag or canister is full and the vacuum has nowhere to store the dust it is collecting. Empty the canister or bag. If that doesn`t fix it, the vacuum filter needs to be cleaned or changed.
The bottom line is that Shop-Vac units shouldn`t be utilized without a filter. The vacuum will work without one, but it might not work better. Numerous other consequences might occur. You may create an even bigger mess than the one you needed to clean.
STEP 4: Empty the canister.

Your shop vac has a built-in safety device that stops the vacuum from filling once it`s full. There is a ball or puck in the filter attachment that floats, and when the water reaches an unsafe height, this device blocks the suction.

As a rule, most of the smaller canister or shop-type vacs use high-speed vacuum producers. These tend to run at a very high rpm, which can reduce the vacuum`s lifespan to as little as 800 hours — or about 18 months, assuming you use your vacuum for about three hours each day.
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.
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.

Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
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.

Most manufacturers recommend you change your filter on average every 3-6 months. However, it is recommended to change your filter even earlier depending on usage and allergy care. Most newer vacuum models use more than one filter. Please refer to your manufacturer manual for further assistance on locating your filter.
Since the filter is made of paper, you can clean it with water, but you should let it completely dry before reuse. You can also stock up and save by purchasing this filter in a two-pack.
So, you should be using dust bags in your shop vac to prevent the filter from clogging up and because it`s easier to empty out all the dust. If you want to go a step further, you can even add a dust separator. It will save your filter even more by filtering out most of the dust before it even hits your vac.
They`re mostly not rated for continuous use, unlike full HVLP dust extraction systems so expect to see limited motor lifetime when run for many hours continuously.
You`ll need it—the filter prevents dust from blowing out of the top while you`re cleaning. For wet surfaces, however, you`ll need to remove the filter entirely. Liquids will damage filters, and you could even potentially ruin your vacuum if you suck up water before removing the filter.
Space is a vacuum, and there`s no atmosphere, and no atmospheric pressure. Because there`s no atmosphere, there`s no outside pressure to create suction. So, despite their usefulness to us on earth, suction cups can`t help astronauts in space.
Why does my Shop-Vac® wet dry vac blow dust back into my room? The dust isn`t being stopped by the filter and is being exhausted out of the blower port and back into the air. This can be caused by a hole in the filter, the filter not being properly installed, or the dust being too fine for the filter.
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!
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.
Use the Shop-Vac® Foam Sleeve for picking up wet messes when used alone. The Foam Sleeve is also required when using reusable dry filters. The approximate size of the foam sleeve is 8 inch diameter and 6.5 inch high. The foam sleeve is required unless you are using a cartridge filter.
More powerful than the average Hoover, more versatile than the typical Dyson, and tougher than your pet Roomba, a shop vacuum is a must-have for any household. These cleaning tools can suck up almost anything.
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.
We have two possible ways of adjusting the pressure in a vacuum system: first, by changing the pumping speed (altering the speed of the pump or throttling by closing a valve); second, through admission of gas (opening a valve).
Vacuum suction pressure in adults is 120mmHg.

The lowest vacuum pressure is recommended to reduce the risk of hypoxia and tracheal mucosa injury. However, the pressure has to be strong enough to remove the secretion. Usually, it`s between 80 to 120 mmHg.

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.

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.

I have a Simplicity S24 canister vacuum. It’s about 3 yrs. old. In the past year I have had it in the shop 4 times because when using the rug piece, the piece turns on & off, on & off. The actual vacuum doesn’t… just the rug piece. I recently spent $65 on a new part, after spending countless dollars the other 3 times it was in the shop for this problem. I’m ready to buy another name vacuum altogether as I feel this vacuum is not worth the money that was spent on it. I’m very frustrated.
ANSWER : Repair shop has not fixed the problem? complain until they fix it properly. This is a pressure fault / jamming issue or slipping drive. Repair shop should have fixed it 1st time.

My Shop-Vac 5870400 was working just fine, and then one day while i vac the floor its just stop working, tried to turn on/off a few times, swicth to different outlet. i did even tried to open it, but found no burn or anything that suspicious. i never drop nor used outside, only inside the house for normal vacumm. please help. thanks.
ANSWER : Same thing just happened to mine. My solution is to get another one but a different brand. I think it should have lasted longer than four years of fairly light usage. From what I read, if it does as we both described, the motor is shot and not worth replacing.

We have a Bissell Proheat Cleanshot 2X Model 9500 Steam carpet cleaner. The first time we used it things were great. The second time we used it it left tracks in the carpet. We have no idea what caused this. We tried using the machine on an entirely different carpet and it did the same thing. After vacuuming the carpet about 10 or 12 times, the tracks are still embedded in the carpet – HELP!!!! We’re read and reread the manual and contacted customer service and received no help.
ANSWER : First things first. It’s only the second time you have used the machine, so it must be fairly new. If you have a receipt and the unit is less than a year old you should take it to an authorized Bissell repair center and have the machine inspected under warranty.
.
.Otherwise, The jets on this unit clog easily, there are two of them and you can locate them under the recovery tank towards the front of the machine, and blow them out with an air compressor. To prevent the jets from clogging in the future make sure to flush all shampoo out of the machine with clean water when done using it. That is most likely your problem.
.
.If it is leaving black streaks on your carpet it could be coming from a burnt belt or melted brushroller part, in which case inspect the belts and brushrollers and replace the damaged pieces.
.
.I hope this helped
.
.Good Luck

My upright kenmore progressive vacuum will not suction up when using the sweeper. It will suction things when I use one of the tools. I have put in a new bag and have tried to see if anything is blocking the bottom. It sometimes makes a very loud noise when I try to vacuum. If I press the intell clean on and off yellow button the noise may go away but it still does not work.
ANSWER : Double check hose placement, making sure you have the hose inserted into the correct slot. The long attachment nozzle stores in the front hole on the right, and the sucking hose inserts into the rear hole on the right. I know this is too simple of a solution, but worth double checking. Our cleaning service claimed our Progressive upright had quit sucking when vacuuming, and that was the problem. They had used the attachments and then reinserted the hose into the attachment hole. It also caused the vacuum to be very loud as the main sucking hole was open. Hope it’s an easy fix and not something serious.
