How to Identify and Fix Common Vacuum Problems ?

Dirty or blocked filters will cause a loss of suction and potentially cause the motor to overheat and cut out. Unlike other Dyson vacuum cleaners, the DC01 does not use washable pre-motor filters so you will need to buy replacement DC01 filters.
The simplest place to start: empty your dirt container. Debris in the main cyclone passage will cut suction rapidly. If the container was really full, you should also check the filters because they can get loaded with dust if the Dirt container is too full. Test the vacuum, and see if the suction is back.
If you find that your machine is turning off intermittently, the filter in your vacuum is most likely full and covering the ventilation system. Remove the filter, then empty and wash it. Allow the filter to dry for at least 24 hours, or until it is completely dry.
There are two filters in a Dyson DC04, the first being the pre-motor filter which can be found at the top of the removable bin and motor unit. This filter can be separated and should be cleaned regularly or whenever it gets dirty, as a dirty or clogged filter can lead to performance and suction issues.
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.
Besides getting jammed with dirt and debris, the major problem that cordless vacuums face is a weak battery or failing recharger. Some cordless vacuum batteries are easily replaced while others are not and require that the entire unit be replaced.
Check the LED light to determine the battery level. A solid blue light indicates that the machine is in normal operating mode. A flashing blue light indicates that there is no power, and the battery needs to be charged for a minimum of 3.5 hours.
To reset the Brush bar press the Brush bar control button twice or switch the machine off and back on.
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.
Suction pressure should be kept at less than 200 mmHg in adults. It should be set at 80 mmHg to 120 mmHg in neonates.  The catheter size used for suction should be less than 50% of the internal diameter of the endotracheal tube.
The suction control slider is located at the front of the cleaner head. The ball located between the bin and the cleaner head.
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 battery creates the suction power, so some cordless vacuums lose suction as the battery starts to deplete. Cordless vacuums with a lithium battery last longer and provide consistent suction power, but only the best cordless vacuums can perform as well a plug-in vacuum.
Your Dyson vacuum cleaner may include one or more filters that need to be cleaned to keep your machine operating at its best. Washing your Dyson filter is quick and easy.
Because there are so many different models of Dyson vacuums, there are many different filters. While most filters will need to be replaced every six months to a year, some are washable. These washable filters can be replaced less frequently and can be cleaned using hot water.
In many cases, you probably can repair a Dyson yourself, especially when it comes to common issues (see below). However, even if your machine needs some extra TLC by a Dyson expert, it can be worth getting it repaired.
If there is a strong burning smell coming from the motor area of your Dyson DC14 or DC07 then it is most likely that your motor has burnt out.
Summary. Dyson batteries should last around 2-6 years before needing to be replaced. This wide range reflects the fact that how you care for and maintain the battery will affect how long it lasts. If you want your vacuum`s battery to last longer, make sure it`s stored at room temperature.
When your Dyson no longer powers on even after charging the most likely cause is a damaged battery. This means the battery will no longer hold a charge and will need to be replaced. Once a new battery is purchased you can learn how to replace it by visiting our battery replacement page here.
Description. This genuine Dyson vacuum part is the reset switch for the Dyson DC24 and D25 uprights. This switch needs to be activated if you experience a power surge while vacuuming, and your vacuum turns off as a result.
Plug your machine into a working plug socket and press the yellow `Test` button. Once the red `Reset` button has popped out, unplug your machine from the plug socket. While unplugged, press the red `Reset` button. Plug your machine back into a working plug socket and test the power again.
Suction is the air pressure differential between areas. Removing air from a space results in a pressure differential. Suction pressure is therefore limited by external air pressure. Even a perfect vacuum cannot suck with more pressure than is available in the surrounding environment.
Suction pressure is the negative difference in pressure between two places that drags liquid or gas from a higher pressure state to a lower pressure state. The suctional force in plants is caused by transpiration. This force aids the plant in obtaining essential minerals from the soil.
