And with the plastic cone

It's kind of hard to see

And for fun

I put them in low speed and took a measurement the 75th actually outperformed the triple crown significantly

But

When switched into high speed the triple crown took the lead

And hoses

I used the hose from the 75th anniversary on both machines the Triple crown beat the 75th by about .5 it's hard to get a seal on the end of the hose so i did end up with a few different numbers including 4.5 triple 4.0 75th.

As a side note, it is clear that the performances of the machines more or less fell in line with the POWER of the machines. The ones with the highest airflow had the better cleaning results in this particular situation. The biggest exception was the Rainbow, which had wimpy airflow but still performed in the middle of the pack. There are SO many variables involved with carpet and vacuums that it is notoriously difficult to "prove" one machine superior to the other. Variables include the state of wear on carpet (slightly worn carpet holds more soil due to matted fibers), the fact that carpet doesn't soil uniformly by nature (people usually walk in certain paths), carpet material, etc. All of this bears on performance of any machine. I also noticed that generally speaking, the machines with the smaller power nozzles performed the best (wide nozzles dissipate the suction/airflow more than smaller width nozzles). I am of the opinion that 12" nozzles are the best, but it's a trade-off again because you can't cover as much area as fast. It's still loads of fun to play with the machines like this.
