How to Identify and Fix Common Vacuum Problems ?

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.
To ensure proper recovery on a carpeted surface, the beater bar should be set at a height where the bristles just touch the tips of the carpet fibers. Most individuals set the beater bar height at its lowest setting due to perception that this will grind into the carpet fibers and recover more.
For a vacuum cleaner to glide easily on a carpet, air must flow into the nozzle and through the machine. Block the air flow and the vacuum seals itself to the carpet and is hard to push. And, unfortunately, that`s what many consumers have discovered when their new carpeting is installed.
There is an adjustment piece at the top of the handle where you turn it to adjust the suction setting. This is the only way to adjust to different carpet heights and rugs. The power button is also two settings. One setting for bare floors and one for carpet.
You Need to Change Suction Power Settings
One of the most common reasons for a vacuum that`s hard to push is using the incorrect suction setting. Most people want to use the maximum suction setting all the time, when in some cases this isn`t necessary.
Overheating motor causing an automatic shutoff
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.
Roller leveling is essentially a bending process. The out of flat part, sheet or plate is deformed by a series of alternating bends. These alternating bends are created by passing the part, sheet, or plate between upper and lower sets of leveling rollers.
To adjust hydraulic lifters two fingers spin the pushrod as the lock nut is gently tightened. When resistance is felt on the pushrod, that`s zero lash. The adjuster is tightened to specs then the setscrew locks it in place. When changing valvetrain components always check rocker arm geometry.
Every standard sliding glass door has adjustable rollers that help it slide back and forth within the track. On the bottom portion of your sliding glass door, you should see a small hole on each side of the door. These holes hide the adjustment screw for the coordinating rollers.
If you want to remove as much dust, dog hair, and cookie crumbs as you can, properly setting the height on your vacuum cleaner can make a big difference. Like all the extra attachments and hoses that come with your vacuum, tweaking the height adjustment knob on the base ensures you get the best clean possible.
The international standard usually divides the vacuum into four levels: low vacuum, medium vacuum, high vacuum, and ultra-high vacuum.
While extreme suction power may offer peace of mind to homeowners who want to feel confident that their vacuums are effective at sucking up dirt and germs, it can be very damaging to your carpet and should be avoided! For high pile and premium soft carpet, be sure to avoid vacuums with concentrated or sealed suction.
Often when your machine is not picking up it is due to loss of suction. If your vacuum cleaner turns on but won`t pick up on carpet or bare floors, something is impeding suction. You may need to change the vacuum bag, unclog the hose, replace/clean the filters, replace the hose, change the belt, or repair the motor.
If the vacuum does not stand on its own, the vacuum`s latch may be broken. Call customer service to inquire about latch replacement options. When you buy the vacuum you have a 5-year warranty, so broken pieces are easily replaceable. You can purchase replacement parts either on Amazon.com or on Shark`s website.
Check for a clogged hose or filter; unclog the hose and replace the filter. Wait 45 minutes for the vacuum to cool; then plug in the vacuum. Turn the power switch to the “I-On” position to start the vacuum. If the vacuum still does not start, contact Customer Service at 1-800-798-7398.
We have two possible ways of adjusting the pressure in a vacuum system: first, by changing the pumping speed (altering the speed of the pump or throttling by closing a valve); second, through admission of gas (opening a valve).
The maximum change in pressure produced by a vacuum pump is limited; it can never be higher than atmospheric pressure. Plus, as vacuum increases, the volume of air passing through the pump drops continuously.
If there is something that has become caught in the hose in another part of the system, the airflow will be reduced and can cause overheating and a shut down. Clear out hoses, attachments, and brushes of any hair, dirt, and debris. This will allow for restored airflow and should get things going again.
This usually occurs if the dust cannister is too full or the filters are clogged and the motor wasn`t getting enough cooling air passing over it.
The Hoover® WindTunnel Whole House Rewind is ideal for Whole Home Cleaning from floor to ceiling and delivers powerful performance on every surface. WindTunnel technology and Multi-Cyclonic filtration lifts and removes surface debris and deep down embedded dirt with no loss of suction.
A: The drive belt is very tight and somewhat difficult to install. Q: These belts break after about 5 uses. I vacuum every day.
Floor cleaning options – The Hoover Windtunnel offers five different floor cleaning options. Each of these options are designed to be used on a variety of surfaces. Some of these surfaces include hardwood floor, low pile carpet, and high pile carpet.
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.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
