There are several causes for this, such as a hole in a hose, or a leak in one of the seals or valves on the machine. Each of the valves, seals, and hoses should be checked to ensure that there is no damage or leak. If there is a leak or damage, a replacement can be ordered and quickly installed to resolve the issue.
Look for any dirt that could have impeded the suction. If your unit has a rotating brush, remove it to gain better access to the opening. Also, always check the point where the hose and vacuum connect. A loose connection here will compromise the airflow and reduce the suction.
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.
Hesitating Engine With Heavy Load

If your fuel filter water separator isn`t working properly or is clogged, then water and other pollutants could be mixing into the fuel injector and causing damage inside your engine. You`ll also know there`s an issue if the check engine light switches on.

How Does it Work? After wastewater passes through filters to separate out the largest solids, it is funneled into the oil water separator to undergo treatment. In most cases, the wastewater travels across a series of chambers. These chambers help to separate oil, water and sludge into three distinct spaces.
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.

They use them in their firing room and to protect their historic artifacts. The clean room and the elaborate steps taken before entering it are vital to the success of every Hubble mission.
It does this by literally “water washing” the air. Air pulled into the Rainbow is cleansed through a swirling water bath and then is filtered through a HEPA neutralizer, returning fresh, water-washed air to your home.
Overall, if you`re interested in a vacuum that collects dust and dirt efficiently, a dry vacuum cleaner is for you. However, if you`re looking for a vacuum that sucks up larger and bigger quantities of debris and collects water safely, a wet vacuum cleaner would be recommended.
Vacuum leaks can develop in many locations, including the intake manifold, throttle body evaporative emissions system, power brake booster, and several other places, because some vehicles have a multitude of vacuum hoses.
Dangers of Ignoring Vacuum Leaks

As the vacuum pressure spurts out of the leaking hoses, it can overheat the engine, disable the engine systems it powers, and even create a damaging compression and timing issue.

The basic trick to maintaining water separators in cold weather is draining them daily. Obviously, the time to drain is just before shutting down while the fuel and any separated water are still warm.
You can prevent fuel pump clogs by purchasing quality gasoline and keeping your tank full. If your automobile is having a hard time starting, accelerating, or sputtering and stalling, you might have a clog in your fuel system.
“Fuel/water separators are predominately located on the suction side of the lift pump, so any leaks will result in air being sucked into the fuel while the engine is running. These same types of leaks can cause fuel leakage when the engine is shut down.”
A water separating fuel filter is designed to catch the impurities or water before they reach your engine. The principle behind this filtration system is surprisingly simple; the top of the filter consists of a paper element and the bottom of the filter is a holding tank or bowl.
Water buildup in the water separator that isn`t drained will cause corrosion to the housing. This corrosion will spread to different parts of your fuel system including the engine. A simple fix is to drain this water when the “Water in Fuel” light illuminates and periodically install a new secondary fuel filter.
Add a few drops of soap or detergent into a bowl of hot water. Submerge the filter and squeeze it so it absorbs the cleaning solution. If the water becomes dirty, empty the bowl and refill with more soapy water. Once the water runs clear after soaking the filter, take it out and rinse the suds away.
Your filters get clogged with bacteria, dust, smoke, mold, and other particles. These can all affect the air quality in your home as well as the performance of your vacuum`s cleaning abilities, if the filter is clogged you will find the suction and general performance of your vacuum will be minimized.
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.
check for leaks or kinks in the tubing. ensure the filter is not wet (keep a backup filter with your supplies) ensure the float shut-off is not activated (if this is part of your suction machine) check for canister leaks and cracks.
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.
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.
It is the only vacuum that is a certified air purifier and is designed to run 24/7 on a lower speed to purify the air in the home. The unique difference is the water. All dirt and dust is trapped in a basin of water so that no debris can re-enter the home atmosphere.

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.

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.

Vacuum smells I have a 6 year old rainbow vacuum model E and it smells terrible everytime I use it. Probably because often times i don’t remove the water basin after vacuuming and just let it sit. It’s my own fault however now I don’t know what to do to get rid of this terrible smell. I’ve water cleaned the hepa filter, not able to remove the separator screw to clean. Can you give me some suggestions?
ANSWER : In addition to vinegar, baking soda (sodium bicarbonate) is also an excellent remedy for many odour problems.

Try generously sprinkling baking soda on a rug you wish to clean, and afterwards, vacuum up the spot.

Rugs, and dirt may be broomed beforehand, and you may want to spread the soda over a large enough area to avoid having a small “clean spot”.

Repeat as necessary, and buy the bigger boxes of baking/washing soda. It has many more great uses that you can discover.

My kids were in charge of the Rainbow, but they moved out. My husband surprised me by cleaning a dirty rug. Neither of us know how to use the Rainbow, but I at least know that you’re supposed to use water. Will it damage my Rainbow that he did not use any water when he vacuumed?
ANSWER : Your Rainbow might have been damaged. It would be advisable to take the machine to a shop and have them do a cleaning on it. The water is the filter, and there is a separator between the water and the motor. The separator only prevents the water from entering the motor. The dirt that goes in the water is no longer airbourne, so it cannot enter. Without water, the dirt is still airbourne and some of it could have entered. I am sure that most of what was picked up landed in the basin. Is the separator(the little nut on the bottom of cleaner holds this in) full of fluff? Take off the separator nut(there should be a wrench/toothbrush tucked in under the cleaner that is used to remove separator and clean it.) Is there fluff visible up in the machine? If so, definitely take it to a shop. The separator must be cleaned after every use. Never store water in the basin. Those are the 2 main rules for care and use of your Rainbow. Well, good luck with your Rainbow. They are truly great vacuums. Let me know if this helped you. Thanks Rene(the VAcuum Doctor)

I do not have my users manual and have never vacuumed wet with this vacuum. How do I change it from a dry to wet vacuum.
Can’t find my manual and I need to use the shop vac for water in basement, do I have to change the filter or what
lost my user manual never used it to pick up water. need to know how to puit it in wet mode i want to clean the dirty water out of my pool.
ANSWER : .Vacuuming Liquids
.1. When picking up small amounts of liquid
.the filter may be left in place.
.2. When picking up large amounts of liquid
.we recommend that the filter be
.removed. If the filter is not removed, it
.will become saturated and misting
.may appear in the exhaust.
.3. After using the vac to pick up liquids,
.the filter must be dried to reduce the
.risk of possible mildew and damage to
.the filter.
.4. When the liquid in the drum reaches a
.predetermined level, the float mechanism
.will rise automatically to cut off
.airflow. When this happens, turn off
.the vac, unplug the power cord, and
.empty the drum. You will know that the
.float has risen because vac airflow
.ceases and the motor noise will
.become higher in pitch, due to
.increased motor speed.
.IMPORTANT: To reduce the risk of damage
.to the vac do not run motor with float
.in raised position

My rainbow vacuum is spitting water – Rainbow Vacuums
ANSWER : Where is the water coming out? If it’s coming through an exhaust port, then it’s gone through the motor, which will ruin the motor. If the motor does still run, stop using immediately and take it to a repair shop for thorough drying and possible cleaning. This must be done immediately to prevent rusting. It may already be too late, and a new motor will be necessary.

I have a bissell quickwash 1950-e. I bought it Jan. 2006, and have only used it 8-10 times, I live in a very hard water area, so I though if I put some vinegar in with the cleaning solution it would get rid of any hard water deposits, unfortunatly the solution went lumpy in the tank and stoped spraying out water, I have opened it, hose clean, sprayer not blocked, x at bottom of water container when depresed water trickles out, component that opens the x when water container placed, also ran wate
ANSWER : Hard to say what is causing your problem, replacing the cap and insert on the water tank may help, part #2041111, even tho it may trickle out water when depressed, they can still be bad. The other thing would be the rod not relesing the water like it should. The big draw back to this model is Bissell has obsoleted all of its parts and most are no longer available. Might be wiser to buy new.

I have a Bissell Pro 2x carpet cleaner. The water heats properly as well as spraying the cleaning product. However, when I go to suction the water from the carpets, the 2 in 1 water tank bladder works properly but there is no dirty water outside the bladder. I have only used this carpet cleaner ~ 5 times and in the beginning I had to empty the suctioned water quite frequently as it was dirty and it could not not hold any more water. So I have done 1 room and all the dirt remains in the carpet
ANSWER : Check that the suction cone is not blocked. Check that the filter or hose to the bladder isn’t blocked as well.
