I'm watching the infomercial now
When they show those HORRIBLY dirty vacuums, filled with so much dirt looking like they came out of a landfill after 10 years - so dramatic.
I have to admit, I can see that horrible shark round foam filter they pull out loaded with dirt actually being true. I have a Shark, and I clean the filters with another vacuum after every use. He's right about the suction/airflow, but wrong too. For example, if I clean my entire house with my shark, and it still has plenty of airflow with a full bin..so yea, airflow cleans, not suction - but they act like if you start cleaning with a bagless vacuum, as soon as you make one pass, the airflow is completely gone......Not true!
