    Get Out More Dirt

    The most important part of carpet maintenance is 
    removing and disposing of accumulated dry soil.  The
    removal of dry soil will improve the air quality
    indoors, extend carpet life, and help to maintain
    the carpet.  Keeping regular maintenance on your
    carpet is one thing, although being sure you have
    the right equipment on the job is another.

    The Green Label
    For vacuum cleaners, the CRI (Carpet and Rug Institute)
    has developed a Green Label testing program.  The
    CRI developed the performance protocol with the
    goal of protecting indoor quality, keeping all
    surfaces as clean as possible, and all without 
    putting dust back into the air.

    The Green Label program helps to identify vacuum
    cleaners that meet three different types of criteria:
    1.  Removing soil.
    2.  Keeping dust out of the air by 
    containing it within the filtration bag and the 
    machine itself.
    3.  It doesn't damage the carpet and helps
    to keep the appearance looking good.

    The tests for determining the certification of a
    vacuum cleaner were developed by carpet and vacuum
    experts and reviewed by scientists with experience
    in maintenance and the quality of indoor air.

    Soil removal
    The soil removal protocol will require that the
    vacuum cleaner remove a specified quantity of soil
    from the test carpet in four passes.

    Dust containment
    The protocol for dust containment will dictate the
    total amount of dust particles that are released
    into the surrounding air by the action of the
    brush rolls, through the filtration bag, and any
    leaks that come from the vacuum system.  with this
    test, the vacuum cleaner can't release more than
    100 micrograms of dust particles per cubic meter
    of air.

    Carpet retention
    The testing protocol for appearance retention will
    require that the vacuum cleaner not adversely 
    affect the appearance of the carpet, based on
    a year of normal usage.

    If a vacuum cleaner meets all three of the above
    requirements, the manufacturer may then display
    the official CRI Green Label on it's brand of
    vacuum cleaner.  The CRI tests canister and upright
    vacuums, wide area vacuums, and even walk behind
    types as well.

    Matching machines
    Looking for that important Green Label is the first
    step to providing longer carpet life and cleaner
    air for your home or office.  The next step is 
    selecting the proper vacuum cleaner for a specific
    area.  You can think of vacuum cleaners like 
    screwdrivers, as you wouldn't want to use a Phillips
    head screwdriver to remove a flathead screw.

    In the bigger, more open areas, a wide are vacuum
    cleaner or sweeper can produce excellent results,
    as well as an increase in productivity.  The 
    average 14 inch upright vacuum can clean at a rate
    of 3,000 square feet per hour, while the average
    walk behind can clean at a rate of 40,000 square
    feet per hour, and also lift the pile of carpet in
    high traffic areas where the carpet fibers are 
    subject to crushing and matting.

    The two motor upright vacuum cleaner is an excellent
    choice in areas such as executive offices, lobbies,
    conference rooms, and break areas.  A two motor
    upright can provide grooming of the fibers in the
    carpet and removal of the dry soil.  Most uprights
    with two motor setups will also have a removable
    hose and on board accessories for cleaning other
    areas as well, such as vents and chairs.

    Along with the type of area, you should also give
    some thought to the needs of the operator.  If
    you are a manager, you should look for vacuums
    with ergonomic features, especially if the vacuum
    will be used for long periods of time.  

    If it isn't ergonomically designed, it could result
    in injury to the operator.  At the very least, the
    cleaning operator might want to avoid using 
    vacuum cleaners that could result in injury.
