I am not trying to attack anyone, but am just getting confused when eight or ten posts are defending this machine, then telling it's shortfalls, then ripping someone for saying something different about it, then declaring it as crap. 

It is possible to have buyers remorse when spending a great deal of money on any item.   Though the "flour/baking soda" test is one test.  I think in the long haul you will find the Maytag / Tacony machines are very capable. 

In your findings you will demonstrate what we have been talking about with Kirby's "seal" on the carpeting which allows it to pull upward and allow airflow underneath.   Though the Maytag machine doesn't do the seal per se, it does have good agitation and air-flow. 

Besides if you vacuum regularly, there is little chance for dirt to migrate to the bottom of your carpeting, and hence, you will have a great machine giving satisfactory results. 

Quit torturing yourself.  Live with your purchase or return it.

Reviews are usually done in one cogent writing, Not scattered post.  Writers will usually gather their data, organize their thoughts,  and then present it in a succinct  manner.  If they have something to add they usually go back to their original post and add to that one under the heading of that machine.  What they don't do is create a new thread for each gripe and wonder.  As a paid member here I have the right to read or not any post there is.  I also have the right to respond to said threads if I wish. 

As I said I was not attacking only making an observation.  Click your My Post button and refresh your memory if you must:

"I have noticed on my Maytag 1200 the suctions through the hose is not all that great. "

"I have to say, it is frustrating to vacuum under furniture with the Maytag,"

"Response to Rob
Rob, that statement doesn't make sense as the Tandem air model I have is an expensive premium vacuum"

"Changes I Would Make to my Maytag 1200"

PLEASE NOTE I like the Maytag

"So, my new Maytag M1200 came today and I just used it in two rooms I vacuumed two nights ago. I was quite surprised at how much dirt, dust and cat hair it got out of the carpet."

Again, please don't take this as an attack, only constructive criticism of your varied reports.

  I, like others here, do appreciate reading other people's experiences and thoughts regarding their collection. 

I am, however, sorry that you were not mature enough to accept criticism. 

I flat out said you are acting IMMATURE.

"Let it go" is very good advice.  Review a machine once, not daily,  then "Let It Go".

Try your test with salt, or fine play sand.  It's texture is closer to grains of dirt you will find in household dirt, it is not as easily pulled through the  carpet weave, and not so clogging on the bag pores. 

The "sand test" is what we used to show in Kirby demos.  When you pull up an old carpet you don't find flour or baking powder under it,  you find sand.  Fine, fine sand.
