How to Identify and Fix Common Vacuum Problems ?

Suction too high
If the vacuum is hard to push, the suction could be too high. Make sure the power button is on the right setting for the respective surfaces. Position I is for bare floors and position II for carpets and rugs.
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.
Replace the Brush Belt
If the vacuum is still hard to push, tilt it back far enough that you can inspect the moving brush while the vacuum is running. Be careful to avoid getting too close to the moving parts. If you see that the brush is not turning, that means you will need to replace the brush belt.
If the wheels have hair, dirt, or any other obstructive objects in them, the wheels may clog, making the vacuum difficult to push. If a clog occurs on the rotating wheels, it may also be difficult to turn. Check underneath your vacuums for these obstructions, and remove if necessary.
First check the airflow valve located under the handle. Sliding this open may make it easier to push your vacuum. It could also be that your suction is set too high. To fix, use the suction controls on the canister to adjust the suction settings.
As the water slowly evaporates and the carpet dries, the residual soap and chemicals dry into the carpet fibers. It is this residue that gives the carpet a stiff, sticky, hard or “crunchy” texture. It is quite similar to how your hair would feel if you rubbed shampoo into it but did not properly rinse the shampoo out.
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.
According to our tests, the Shark Vertex Powered Lift-Away Vacuum is the easiest upright model to push, even on medium- and high-pile carpet. We also found the Bissell CleanView Swivel Rewind Pet Reach Vacuum Cleaner easy to maneuver on flat surfaces, though it was a little cumbersome when cleaning stairs.
Vacuum cleaning is one of the household chores that may leave us with pain. That is because while using a vacuum cleaner, weight is transferred back and forth between the back and the front lower limbs. Vacuum cleaning also involves bending which indirectly puts pressure on the lower back.
Make sure that this switch is on carpet mode. Belt Broken: Shark brushes are operated by a belt. If this belt breaks, the brush roll will not spin. You can easily check the belt by either removing the base plate on the Shark or – if you have some experience – by spinning the brush roll by hand and feeling for tension.
Only “works” on bare floor and high pile carpet. Works a little better on high pile, but pulls up some of the rug with it.
One of the most common reasons for your shark vacuum (and most vacuums for that matter) making a loud suction noise is because there is a blockage. They`re a very common issue, and easily fixed. Blockages occur when there is a large enough build up of dirt or dust that it blocks the air flow to the vacuum.
Check the hose for any clogs
If your Shark vac has a hose, feel along the length for any lumps. That indicates a clog that`s causing your suction issues. See if you can break the clog by applying gentle pressure with your hands, or gently move it to the end of the hose to remove it.
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).

This vacuum has adjustable suction levels and brush roll speeds to maximize your cleaning efforts.
Set a steam iron to medium-high heat. Place the iron on top of the wet towel and move the iron over the towel for about one minute to infuse the carpet fibers with moisture. Remove the towel and fluff the fibers with your fingers or a carpet rake. Repeat if necessary and vacuum the restored area.
Fluff it up
Matted carpet can easily be brought back to life. Spritz a little warm water onto the matted area then gently blow-dry with a hairdryer as you fluff the carpet fibres back into place with your fingers, the edge of a spoon or a hairpin. Allow the carpet to dry completely before walking on it.
For most models, the lowest setting is optimal for bare floors or thin carpeting. The middle setting offers the best suction for slightly fuller carpets. The highest setting is best for plush carpets or area rugs.
How often should you vacuum fabrics, carpet, and rugs? Anything with fabric or upholstery needs frequent vacuuming. Dust settles deep into the fibers, holding onto pollutants, bacteria, and unwanted smells. Plan to vacuum carpet and area rugs at least twice per week, even if they don`t look dirty.
A: We would like to let you know that moving the base by a few inches wouldn`t change anything. however if you are wanting to move the base from one wall to another wall or one room to another room you would need to remap your home.
Also, unlike the iRobot vacuums, the Shark doesn`t have a self-empty automatic bin sensor. That means that it doesn`t know when its bin is full and will just keep going.
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.
If this is normal air pressure at sea level, then the force is around 15 lbs for every square inch of the surface area of the container. If you`re deep underwater – then it could be tons per square inch.
The biggest cause of carpet becoming crunchy and gross is simply that they were not cleaned properly. If your carpet is crunchy after getting cleaned, that means that particles of the shampoo, detergent, or chemicals that were used during the cleaning process were left behind in the carpet fibers.
