As with most things in life, there is really nothing
free. The two most claimed advantages to bagless
vacuum cleaners were lower operating costs and
better performance. As far as the cost issues go,
all vacuums must filter the exhausting air they use
to carry the dirt into the collection area, as they
would otherwise simply pick the dirt up from the
floor and spit it right back out.
Whether you have a bagless HEPA filter, a pre-filter,
or disposable bags, they all need to be changed at
some point. With the average life of a vacuum
cleaner, you can expect to spend the same on either
collection system for filters, but if you value your
time, you can expect to spend quite a bit more on
a bagless system.
To keep your bagless vacuum cleaner operating at
peak levels, you'll need to empty the dirt container
when it is full and perform regular maintenance on
the filter. The type of filter the vacuum uses will
determine just how much service will be required,
although most use a pleated HEPA filter.
Cleaning
Even though the claim of better airflow performance
with bagless vacuums is true in a sense, over the
life of the vacuum you'll get the same, or maybe
even better performance from a bagged vacuum cleaner
system.
With bagged vacuum cleaners, the performance will
start at 100% with each new bag then slowly drop
as the bag starts to fill. Just how quickly the
performance drops depends on how well the bag is
constructed. With the average vacuum and the average
bag, you may replace the bag every 3 - 4 weeks
