You'll find three main features to look for. How it loosens the dirt, how it lifts the dirt and how little of the dirt it sends back into the air.
You have to have an efficient approach to take away the dirt and dust from your carpet. This is the first cornerstone. Uprights have brushes underneath that open the pile and loosen the dirt. As far as I am concerned the most efficient are those where the brush has it's own power source. These really lift the pile (which is what most people want, a great visual result).This allows more energy to be used extracting dirt (which after all, is what we want, isn't it?). Most people can tell visually if one or the other has been used The pile of the carpet is raised up much more.
Once it has loosened the dirt, the machine has to remove and catch it.Just how effective is it and what factors affect it's performance?The two most commonly encountered filtration systems are bags or cyclones.
Bags, whether paper or cloth tend to work well for a short period. Once they start to clog, their performance drops considerably.Their suction drops dramatically, once the bag has begun to fill with dust.
Cyclonic separators are a step of progress in air cleansers. These work well, specially when they contain multi stage air cleansing systems.{The cyclone, in comparison, removes the dust by spinning it really quickly to ensure that it gets thrown out of the side.|You need a purification
method that gets shot of dust and dirt without obstructing the bag or the filters. The answer is a spinner or cyclone system.|Cyclone systems circumvent this "clogging" issue by using centrifugal force. Remember when you were a youngster and you played on a merry go round? As you went faster and faster you had to hang on for all you were worth to stop being thrown of the outer edge. It's the same for the dirt. It gets thrown out of the airflow and falls into a container.}This process means that the machine functions at nearly full effectiveness most of the time.
In the time I have been involved with carpet cleaning Birmingham, the next part has been crucial.
Once we have solved that problem, we have to look at how it contains the dust and dirt that has been removed.If you have an inefficient machine, then all the removed dust can be circulated back into the room. Have you ever been in a room where someone was vacuuming and you could smell and taste the dust? That is a good example of really bad dust filtration.Very small particles of dust are very hazardous to your health.
Decreasing this "re-distribution" of dust is of paramount importance.Probably the best as far as filtration is concerned is a water filtration type vacuum cleaner.This method works by directing the dirt filled airflow down on to the surface of the water where it is captured and cannot be sent back up into the air.The best type of vacuum cleaner to take advantage of this system is the tub. The machine has to be kept level to make the most of this really effective filtration method.
Basically, you have a large bowl of tap water in the vacuum cleaner. The pipe leading from the carpet head to the machine is angled so that the airflow goes across the surface of the water. As the "dirty" air is blasted through, the dust, dirt, allergens etc, are trapped by the water. The air, meanwhile carries on through the machine. With no real restrictions (as a bag would), the machine can carry on at near full suction.
What would be the best way to design a vacuum cleaner (assuming that patents were not a problem)?
In an ideal world I would go for an upright with a separate motor to power the brush. This would have a water filtration system to capture the dust.You have to find a way of keeping the water more or less level throughout the process (which is difficult, if not impossible with an upright cleaner).
Why not try a powered brush head working off a tub machine using air washing technology? Surely that get us somewhere nearer to the ideal solution?
Your choice will be an important one. It's best to take your time and weigh up the options. If you get it wrong then at best you may have a machine that is totally wrong for your needs. At worse, you could be risking the long term health of yourself and your family.
