don’t have adequate suction that reaches the accessory hoses nor the main one. I’m not sure where to start. I’ve taken the darn thing apart but I can’t see any obvious malfunction. Any suggestions?

Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
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.
This pressure drop behind the fan is just like the pressure drop in the straw when you sip from your drink. The pressure level in the area behind the fan drops below the pressure level outside the vacuum cleaner (the ambient air pressure). This creates suction, a partial vacuum, inside the vacuum cleaner.
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.
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.
Overcharging leads to overfeeding the evaporator with refrigerant, which leads to higher suction pressure. Another possibility is having oversized EXV causes an overfeed to the evaporate, which increases your suction pressure.
Breathing uses the same concept as a straw, but this time your lungs expand, which creates low pressure in the lungs and the outside air is pushed — not sucked — in. There is no such thing as a “suction” cup.
Boil old suction cups to revive them.
Take the pot off of heat and drop your suction cups in for about 30 seconds. Take them out with a pair of tongs and pat them dry on a lint-free towel. Try to use the suction cups right after you dry so they`re still warm and flexible.
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 type of dust collector or vacuum cleaner bag and the size of it affect the suction power of a vacuum. When a vacuum cleaner bag has an extra filter, the vacuum needs a higher suction power. That way, the air will flow outwards through all the filters.
Dyson invested £2.5 billion in research and development
While you might feel that this is the reason their products are expensive, you`re highly mistaken. This investment was mainly to accommodate a centre for their 1,200 employees, 22 laboratories, prototyping space, and areas for collaborative work.
Hot environments speed up battery aging. So it`s best to avoid cleaning the car in hot weather or leaving your vacuum in rooms that experience direct sunlight for prolonged periods. The same goes for cold porches and garages in winter.
How and when to clean/replace your Dyson filter. 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.
We recommend replacing your air purifier filter every 12 months. That`s because over time, filters can get clogged with pollutants, and even let unpleasant odors back into the room.
Any under-sizing (which is a restriction) or other type of restriction in these vital conduits that affects the flow of this refrigerant/oil vapor mixture can cause a multitude of problems from diminished capacity, refrigerant system blockages due to oil concentration even outright failure.
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 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.
The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
Use a mild detergent or a mixture of bleach and water (1 part bleach/10 parts water) and rinse thoroughly. Follow the instruction manual when disinfecting the mechanics of the unit. Never submerge the suction unit. Use disinfectant wipes to clean all outer surfaces, including control knobs, screens and handles.
Suction cup manufacturers suggest wetting the inner perimeter of your suction cups with with warm water to make them stick better and create a tighter seal.
Cupping is an alternative therapy that involves suctioning the skin with glass, plastic, or silicone cups. It may help improve blood flow, boost immune function, remove toxins, and reduce pain.
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.
