We now know that you want an upright with "tools-on-board".
Next is the issue of dust and allergies.
Even if you don't have any allergies, you should still be concerned
about the amount of dust that could be blowing back into your home while
you are vacuuming.
At this time we are recommending SEBO and Lindhaus.
Both of these brands have excellent airflow, great filtering systems,
and some of the longest warranties on the market.
There are others as well, but we feel that for the money spent that
these two brands the best choices out there.
