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. To be spitting everything out the vacuum cleaner has to be blowing when it should be sucking. If the electric motor that drives the vacuum cleaner is wired for a particular polarity it makes a difference which way it was plugged in to the mains. Just in case this unlikely situation is the cause, unplug the vacuum and reverse the plug and plug it in again. If the vacuum works properly there is a problem with the way the electric motor is installed and it needs to be remedied by an electrician The only other way the machine can be blowing instead of sucking is if the drive belt from the electric motor to the fan has been twisted. A single twist would cause the fan to be driven in reverse. Removing the fan belt and straightening it out will solve the problem. If you forget to fit the bag or fail to fit it properly the dirty air being drawn into the vacuum cleaner will be passing straight through the machine and leaving, carrying all the dirt with it.

Fitting the bag properly should solve that problem. The same situation will arise if the bag is seriously damaged and is not capable of trapping the debris. Although the filters should deal with it, a torn vacuum cleaner bag will also allow the dirt and dust to simply blow through the machine. If an upright cleaner is spitting everything out it means that the brush roller is ejecting everything.  There are two ways this can happen. If there is a blockage in the short stretch between the brush roller and the body of the machine there will be no stream of air to drive the dirt into the bag. The dirt will fall back onto the brush roller and out the front of the machine. The other way is if there is a twist in the drive belt of the brush roller. A single twist in the brush roller drive belt will spin it in reverse so that it will eject the dirt from the front of the vacuum. Older cylinder cleaners are unique in that they have hoses which can be connected to either end of the machine.

This means that the owner has the option to select ‘suck’ or ‘blow’. Connecting the vacuum hose to the wrong end will give the impression that the machine is ‘spitting everything out’.good guys vacuum cleaners melbourne Some combination machines can be used for spraying. dirt devil vacuum cleaner bags ukThey have a special option to switch the machine from sucking to blowing in order to use paint sprayers or water sprayers powered by the vacuum cleaner motor. philips vacuum cleaner bags irelandIf yours is such a machine, check that you have it set to ‘suck’ rather than to ‘blow’. I have a bissel 3510-W style 2 vacuum cleaner. It was working fine but after my son did something with it, it now blows instead of sucking and I have no idea why and of course, my son has no idea what he did (teenagers!)

Thank you in advance! Take the hose out of the exhaust and plug it into the suction port. Vacuums use AC motors that aren't (easily) reversible, so it's likely nothing particularly serious. All vacuums have an air inlet and outlet - normally the inlet is at the power head and the outlet is in around the bag/filter unit. Some vacuums have hoses that connect to the blower motor, one for inlet one for outlet. It sounds like your Bissell has this and he flipped these around so that it's now pulling through the filter and blowing out the power head. Make him vacuum for a week as punishment. wow, it's funny vacuum cleaner. By the way - if you are looking for a best vacuum for hardwood floors. i can help you choose the best one Michael W. Smith, MD Jan 6, 2012 -- You vacuum your house religiously to get rid of all the dust, dirt, and bacteria and make sure your indoor air is up to snuff. But new research suggests that some vacuum cleaners may actually be making things worse, not better.

Certain vacuum cleaners spit fine dust and bacteria back into the air, where they can spread infections and trigger allergies. Australian researchers tested 21 vacuum cleaners from 11 manufacturers, including two commercial models. The vacuums were six months to 22 years old, and ranged from less than $100 to almost $800. Brands included Dyson, Electrolux, Hoover, iRobot, and Sanyo. The researchers measured 62 different air emissions. All released some bacteria, dust, and allergens back into the air. Newer and more expensive vacuum cleaners generally caused less indoor air pollution than older, cheaper models, the study showed. Vacuums with high-efficiency particulate air (HEPA) filters released only slightly lower levels of dust and bacteria than vacuums that did not use these special filters. HEPA filters are supposed to remove 99.9% of the pollen, animal dander, and even bacteria from the air. The new findings appear in Environmental Science & Technology. “Both vacuum cleaning and the act of vacuuming can release and re-suspend dust and allergens, leading to increased exposure,” write study researchers from Queensland University of Technology in Brisbane, Australia.

But don’t go throwing your trusty vacuum cleaner out so quickly, says Viviana Temino, MD. She is an assistant professor of allergy and immunology at the University of Miami School of Medicine. “For a vacuum to do more harm than good, it has to be a really old vacuum cleaner that has never been cleaned,” she says. “In general, most vacuums do take up more dust, dirt, and allergens than they release." HEPA filters are still the way to go, she says: “They remove more particles than they release back.” There are other things you can do to keep your indoor air clean. “If you or someone in your home does have indoor allergies, get rid of your carpet,” she says. “If you have throw rugs, wash them once a week in really hot water. This will kill off dust mites and other allergens.”The chances are high that you use a vacuum to clean your carpets in your home on a regular basis. But have you ever stopped and thought about giving the vacuum itself a deep cleaning job?

If you have a Dyson vacuum, we will show you all the tips and tricks to getting a deep clean – which, in turn, ensures a better cleaning job on your carpets! Air Compressor, or a can of compressed air Dish soap and paper towel *Steps 1-5 should be done outside* Empty the canister of any debris. Remove the outer canister shell by pressing the button on the back between the two red pieces. Open the bottom flap and remove the foam filter. Put aside for later. Flip the vacuum upside down, and using a flathead screwdriver, remove the bottom roller cover. Use scissors to remove any hair that may be trapped on the roller. When clean, use the compressed air to blow out any dust or dirt trapped in visible spaces. Put roller cover back on. Put cyclone part of the vacuum over a deep trashcan, and use the compressed air on every single tiny hole (this part is super messy! Make sure that you turn the cyclone part over, and blow the air on the inside as well.

Clean the canister section using the compressed air. *Gather the cyclone, canister, and sponge filter and move inside to water source.* Run the sponge filter under water and squeeze until the water coming out is clear. Run water through the canister. Wash the canister thoroughly with dish soap. Use a damp paper towel to wipe off the cyclone section, and make sure that all the tiny holes are clean, and not plugged. Make sure that all sections that came into contact with water are laid out to completely dry. (At least 24 hours.) Leaving any form of moisture in the canister or cyclone part will cause dirt to clump in the holes, and make routine canister emptying much more difficult. Additionally, Dyson does not recommend running the cyclone section directly under running water! We suggest deep cleaning your vacuum once every 3-4 months. It will both elongate the life of your Dyson vacuum, as well as make sure that your carpeting is getting properly cleaned.
