Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum\015 The lock that keeps the dirt cup (canister) in place will not slide to the lock position. It is only 1 month old. I have tried pushing up gently with dirt cup, tried repostioning the bottom of the dirt cup. Nothing seems to help. It seems stuck. A couple of times it worked with a little exerted effort so I thought it was just jammed or had dirt or somthing lodged in it. Now it will not go back to the locked position and I can not vacuum. I paid $300 and have had it 1 1/2 months. I am very frustrated now.\015

How to Identify and Fix Common Vacuum Problems ?

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

The most common cause of vacuum cleaner not picking up dirt properly is clogged air filter. Remove the filter and either clean or replace it as needed.
If there is a clog in the vacuum, you won`t have good suction and the vacuum won`t work. The clog can be in the vacuum head, the hose or where the hose meets the actual vacuum.
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.
Vacuum cleaners are very simple machines relying upon the flow of air through filters and a bag to clean floors. If they start spitting stuff out it means that the air flow has been reversed or it is not there at all.
Simply plug the product back in or restore the power and then switch off the appliance using the button on the control panel. The door will now unlock.
If a vacuum motor overheats due to poor airflow, the vacuum will automatically shut off. This is most commonly caused by an air passage that is plugged by hair or dirt. Refer to the leaky hose guide to remove the hose, then inspect for hair or dirt clogs.
The most common problem with a vacuum cleaner is also the easiest to remedy: clogs in the hose or attachments. Also the electrical cord, motor, switch, fan, brushes, and motor bearings can all need repair or replacement. The drive belt may need replacing; and the attachments, hoses, and filters may need unclogging.
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.

There are basically only 3 reasons a vacuum sealer bag will fail: The seal line area was dirty/wet/wrinkled when the bag was sealed or made (if made from a roll). Something in the bag punctured the bag. The bag is defective.
The most common cause of vacuum pump failure occurs due to broken belts, electrical problems inside the unit, or vacuum hoses that fail.
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.
They need power to be transmitted to the vacuum to create a suction force that lifts debris. 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.

Dirt cup lock on windtunnel vacuum won’t lock
ANSWER : It may have to be taken off and then re-installed, but if it is only 1 and 1/2 old, then it is under warranty. There is a full year on Hoover vacuums. Just take proof of purchase with you and take it to a warranty repair shop. You should have their 1-800 to call and find the closest shop. Warranties are void if you temper with it.

Our Bissell Cleanview II 3576M does a great job except that the filter cup below the dirt cup gets full very fast and the dirt cup barely has anything in it. To clean the whole house, I have to empty the dirt cup and clean the filter several times. It didn’t use to work this way. It seems like something is missing, a gasket or seal maybe? I don’t think dirt, hair and debris should be going straight to the lower cup and bypassing the upper. I looked at the user guide but can’t see why it’s happen

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

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.

Hoover Mach 3 (Fusion): Dirt Will not enter dirt cup
ANSWER : There is a filter in the top over where the dirt canister clips in, and one under the dirt cannister by the motor. Sometimes removing and cleaning will help if you have not tried it already.

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.

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 : 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.

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.
