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.

One of the easiest ways to increase vacuum cleaner suction is to empty the dust bag or container. Dust containers need to have enough space for airflow, otherwise, they could get clogged and have less suction power. Regularly check your dust compartment and empty or change it when it`s already 70-80% full.
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.

This is done by placing clear disks on each end of the length and hooking it up to a suction pump to bring the hose down to a vacuum of 22 in/hg. Once a vacuum is achieved the length is checked for any leaks or de-lamination.
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.
Check the Rotator Brush and Wheels

Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.

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.
Push a broomstick through the hose to force any large clogs out. Take the end of the broomstick and feed it through the hose. Push the stick in slowly so you don`t accidentally break or puncture the hose. If there is a large clog in your hose, the broomstick will force it out from the other end.
Check the hose for any clogs

If your Shark vac has a hose, feel along the length for any lumps. That indicates a clog that`s causing your suction issues. See if you can break the clog by applying gentle pressure with your hands, or gently move it to the end of the hose to remove it.

Hoover Windtunnel My Hoover Windtunnel is 3 years old. It worked great until yesterday when it lost all suction. I have followed the manual to trouble shoot any possible clogs and could find none. Then I noticed that when I remove the dirt collection cup and held my hand over the vent the suction is fine and strong. So… I replaced the hepa filter thinking that might be the problem. That didnt’ work. The motor runs fine. The suction without the dirt cup inserted is strong. As soon as you insert
ANSWER : Mine does the same thing. There is no suction. I found that there is a door that opens when you tilt the handle in the down possition. I think there should be a spring in place so it can open. Until I find a replacement spring I have to open the door manually throught the opening under the light.

ANSWER : Either the hose has a clog, or the inlet down by the belt is clogged. Is there suction at the end of the hose, if not then it is clogged. If there is suction, then it has to be clogged down below by the brush roll, check that inlet. There also is a filter at the bottom where the dirt cup (and bag) is, check it also.

My Dyson DC17 beater bar motor works intermittedly. I have to almost whack it on the floor to turn it on and then shuts off again. I have checked the belt and it is fine, also have checked for blockages. The switch to turn the beater bar on or off will not work when the beater bar motor is off. the suction is fine though.
ANSWER : Buy a Kenmore for less money

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.

Windtunnel first one used 6 times beater bar stopped working, took apart cleaned and belt was fine. this one had a reset switch for beater bar. had insurance at best buy so returned for a new one. used 2x beater bar not working and not dirty, no reset switch on this one., now back to the store for another? i don’t even want the same one. I wonder how many they are gonna give me. This seems to be a common occurance.
ANSWER : Sorry, you feel like that. I have rentals and 6 windtunnel’s (I prefer the bagged ones) and have never had a problem such as you have described. I think Hoover makes a great vacuum.

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.

I had a shoelace get stuck in the beater bar. I turned it off, tipped it over and untangled the shoelace from the beater bar. When I plugged it back in the vacuum ran but the beater bar was not turning and there wasn’t any suction. Is there a reset switch for the beater bar? Thank you for your help, Janet
ANSWER : Hi Janet. there is a small reset button on the outside of the head next to the brush that you can push to get it to start spinning again.

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;
