How to Identify and Fix Common Vacuum Problems ?

If the device is not creating sufficient suction or powering on, the motor could be obstructed. Unscrew the screws from the side of the Dirt Devil Gator. Once removed, notice the motor device (the largest one) and inspect to ensure no dirt or debris is obstructing or damaging the motor or its fans!
If your vacuum cleaner has lost suction power, it`s time to empty the container. Vacuum cleaners come with various foam or mesh filters. These might get clogged over time if not cleaned or replaced properly. This will cause your vacuum to lose suction.
Vacuum cleaners are fairly simple machines. 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.
1. The dirt canister may need emptied or the bag/filter may need to be replaced – follow the instructions in your Owner`s Manual based on your power unit type. 2. The hose may be clogged.
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.
The powerful airflow from the vacuum can help shake dirt and debris loose and pull them into the vacuum. Without the fan, a vacuum couldn`t work at all. But the roller brush is critical, too. It`s necessary in dislodging deep dirt and stuck debris, and it helps clear a path for air to carry dirt into the vacuum.
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.
Low compression, an intake leak or tight valves also can cause low vacuum at idle. If the vacuum reading fluctuates within the normal range-the gauge needle bounces around a lot-uneven compression (broken rings or leaking valves or head gasket in one or two cylinders) is a likely culprit.
If the brushroll is sticking, it will cause too much friction and put too much strain on the belt. Remove the brushroll and clean all hair, string, and lint from the brushroll bearings. If the vacuum cleaner brush still doesn`t spin after you clean the brushroll, consider replacing the brushroll.
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.
If there`s no suction, the hose is clogged. Attempt to clear debris from both ends of the hose. If you`re unable to clear debris or the hose is damaged, you need to order a replacement on BISSELL.com. Look through and clear any clogs you see in the extension wand.
When you use a vacuum cleaner without a HEPA filter, these particles are stirred up and put back out into the air through your vacuum`s exhaust. Regular filters can`t remove these harmful particulates and this puts the people in your home at risk.
Push harder than you pull
Many people naturally exert more force when they`re pulling their vacuums back than when they`re pushing them forward, but this can leave dirt on the floor. Vacuums are designed to be pushed forward at a rate of about 12 inches per second and pulled back at a rate of 6 inches per second.
If the filter isn`t clean, it can impact the performance of the vacuum. Dirty vacuum filters can restrict airflow so the suction won`t be as strong.
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.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
1. Motorized Brush Head. Sometimes called the “power nozzle,” this large attachment has a rotating brush to clean carpets more like an upright.
Replace filter every 3 to 6 months.
If the device isn`t producing steam, please try the following: Check for any debris or blockages in the head and main body. Empty and refill the tank. Check for any limescale/debris in the tank itself and descale if necessary.
If the Side Brush is not spinning after cleaning, you may need a replacement Side Brush Module. Please visit the iRobot Store – Parts and Accessories, contact iRobot Customer Care, or use an authorized retailer or partner.
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.
Suction pressure should be kept at less than 200 mmHg in adults. It should be set at 80 mmHg to 120 mmHg in neonates.
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.
