It seems that finding a vacuum that really gets the job done is a difficult task. There are so many products on the market and so many only handle the job half way. Many vacuums out there only last a few months or even weeks before they are unable to manage the particle extraction. Why is that? What makes a vacuum actually work and why are Langley Vacuums one of the best choices for finding a quality vacuum? Those are all questions this article intends to address. The mechanics of a Langley vacuum are quite simple; basic principles of physics which result in a lot of work that you don't have to do on hands and knees because of the clever design. The mechanics are designed to create a partial vacuum or drop in air pressure within the cleaner (hence it's title: vacuum cleaner). This causes a suction of air to be created which drives through the intake portion of the vacuum and up into the internal chamber. This suction is caused by the physical principle of air, that high pressure moves to low pressure. The internal fan inside the vacuum creates a low pressure vacuum within by blowing air towards the exhaust portion of the vacuum. This causes a drop in pressure inside, and thus the greater pressure outside the vacuum will cause a suction of air to enter. The next step in the process has to do with friction. The moving air particles brush up against debris and dust. The friction between them causes the dust to ride on the air like a surfboard or like leaves in a stream. The debris gets pulled in with the suction of the air. Most vacuums are also equipped with a rotating brush. What most people don't know, is that brush is designed to kick debris up and out of the carpet, it is not designed to actually sweep debris into the vacuum itself. For that design to work it requires 2 rotating brushes, otherwise the dust is simply pulled in a cycle. the filtration system is the next step of why langley vacuum work. The air and debris pass through a vacuum bag or in most current vacuum system they use plastic chambers with a filter instead of a bag. The air passes through a porous material. The material allows air to easily slide through, but larger particles get caught in the filter where they remain until removed. Modern vacuum's typically implement a series of filtration levels. Larger pieces of debris are collected first, while finer dust is collected in a small chamber with a thicker filtering material. Attachment pieces use this same stream of suction through the hose to channel the air flow to specific points. The air flow diverts to the hose system and creates a stronger or, more correctly, a more focused site of suction. These make vacuuming stares and behind bits of furniture much easier. In the event that your vacuum isn't functioning proper, rather than dumping it and buying a new one, checking the filtration system should be the first step. Most people wait to change the vacuum bag until the suction stops. This isn't ideal but in most cases it doesn't harm the vacuum. What eventually happens however, is that the debris and fine dust collects to such a degree or point, the filter is so loaded that even air struggles to pass through it's pores. At this point the suction system cannot work and stops. The solution is quite simple. Open the vacuum up and replace the bag. If you have a chamber system, it's as simple as removing the chambers and cleaning the individual filters. Langley vacuums have been known to get clogs in the hose itself. A broom handle will often work to push any clogged debris out of the hose.
