The CRI program established a maximum emission of 65 micrograms of particles per cubic meter of air. The backflow resistance on the vacuum cleaner motor can shorten vacuum cleaner motor life.Vacuum Cleaner RatingThe Vacuum Cleaner Testing Program established a minimum soil removal standard (unknown to the consumer) and assigns a pass/fail rating based on the amount of soil removed.

This will help ensure that the vacuum cleaner operator is subjected to less dust than is normally found indoors. In some cases, these high filtration bags reduce airflow (suction) created by the vacuum cleaner motor, reduces soil removal, creates a back flow or resistance on the motor. In the past, Consumer Reports used a vacuum cleaner test procedure developed by vacuum cleaner manufacturers which had a 65% standard deviation of results, so a vacuum cleaner could remove anywhere from 25 grams to 90 grams of 100 grams of test soil and the results were considered identical.Ma. Testing revealed that stiff vacuum cleaner brushes can fray, disentangle, and permanently damage pile fibers. Also, by placing a high filtration bag on an ordinary unit, filtration may be improved, but soil removal may be negatively affected. Current indoor standards have been set somewhere around 100 micrograms per cubic meter of air. In the past, consumers had to rely on the worn path of dubious marketing claims offered by vacuum cleaner manufacturers. We were stunned to find that the environmental chamber they used for vacuum cleaner filtration/particle emissions testing amounted to plastic sheeting draped from the acoustical ceiling tiles in the Consumer reports lunchroom.Even the testing performed by consumer groups like Consumer Reports does not rise to the level of good science. Carpet industry testing revealed that some vacuum cleaners making these filtration claims removed very little soil. After all, it the carpet industry's product that was being harmed by improper maintenance equipment. It appears as if every vacuum cleaner manufacturer is selling indoor air quality, allergen reduction, and health attributes of their unit, but there was no reliable test method of evaluating these claims. In essence a vacuum cleaner that removes no soil, filters every thing that is removed, right? Wow- that's 100% filtration effectiveness , isn't it?

This statement may not be very far from the truth for some vacuum cleaners. In 1996, when we began work on a Carpet industry test method for rating vacuum cleaners, we visited the Consumer Reports Test Facility in Yonkers NY. Many vacuum cleaners can damage the carpet pile fiber, when brush action is too aggressive. The majority of soil tracked into your home is insoluble dry soil and cannot be removed with wet cleaning.The final criterion is particulate emissions.For more discussion of this topic, check the link below:carpet cleaner, carpet cleaner auckland, carpet cleaners. The primary function of the vacuum cleaner is to remove dry soil. In some instances, a few weeks of vacuum cleaner use with a non-conforming vacuum cleaner can simulate the effects of more than a year of foot traffic.The Vacuum Cleaner is the most important tool used in the maintenance of your new carpet.The carpet industry recognized that if the vacuum cleaner industry would not initiate a reliable test method for snow brush with scraper manufacturers assessing vacuum cleaner performance, the carpet industry would have to initiate it's own test procedure
