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.
If the suction is poor at the inlet to the motor, skip down to Filters are Dirty. If you are getting suction without attachments or through alternate airflow paths, you can narrow the problem to a clog in a hose, brush head, or attachment. Otherwise, your issue may be with the vacuum body itself.
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.
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.
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.
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.
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.
High Vacuum May Cause Damage to Your Nipples and Breasts
Too high vacuum may cause pain and eventually may also cause damage to the delicate skin around your breast, areola and nipples. It may also cause a reduction in your milk flow.
Blockage – when a vacuum cleaner becomes unusually loud, it is normally because of a blockage of some sort. This is a problem that is easily solved by turning off the cleaner, check for blockages in the pipes, and remove them. You can also check and empty the canister to remove any possible blockages there as well.
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.
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.
What is a Good Suction Power for a Vacuum Cleaner? An upright cordless vacuum cleaner should have at least 100 air watts to effectively clean a variety of floor surfaces, with the best Samsung vacuum cleaner reaching up to 210W*.
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.
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.
Rough vacuum: 760 to 25 Torr. Medium vacuum: 25 to 1×10–3 Torr. High vacuum: 1×10–3 to 1×10–9 Torr. Ultra-high vacuum: 1×10–9 to 1×10–12 torr. Extremely high vacuum: Less than 1×10–12 Torr.
The suction control slider is located at the front of the cleaner head. The ball located between the bin and the cleaner head.
Next, you need to consider suction power. Typically expressed in Pa (pascals), this is a measurement of how powerful the motor is inside a robot vacuum. A good number to look for here is around 2,000Pa or above for an effective clean.
Producing up to 115 Air Watts, it generates powerful suction on carpets and hard floors.
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.
Your suction pressure increases because the suction valve is being open during the part of the downstroke of the compressor. This creates the cycle of high suction pressure, which damages your refrigerant.
Many moms assume that having a pump with a higher suction strength will automatically mean that they will be able to pump more milk, but in fact, pumping at too high of a setting can actually inhibit your milk production.
Vacuum has no “strength”. The only reason why a vacuum vessel on Earth must be strong is to resist the crushing pressure of Earth`s atmosphere. Also, High vacuum systems do not “suck” matter out of the vacuum vessel.
It is easy to understand that if the container is expanded in volume while still remaining sealed, the pressure will decrease (and a vacuum will be created) in direct proportion to the increase in volume (in accordance with Boyle`s law).
