The salesperson concludes that the Super XL is the better vacuum because it picked up dirt that the old vacuum missed after both were used on the same area of carpet. The Super XL was used second.

The salesperson's argument is vulnerable to criticism because the vacuums weren't tested under the same conditions. Just because the Super XL picked up some dirt that the old vacuum missed doesn't necessarily suggest that the Super XL is better. In fact, the Super XL might have missed just as much dirt if it had been used first. The salesperson should have tested both vacuums individually to compare how much dirt they each collected on their first pass over equally dirty areas of carpet.

The salesperson never assumes that the Super XL picked up all the dirt in the carpet. Presumably at least a little bit of dirt remained in the carpet after the Super XL was used, but this doesn't change the fact that it picked up dirt that the old vacuum left behind.

The salesperson argues that the Super XL is the better vacuum right now. He never assumes that it will still perform better in 10 years.

The salesperson never claimed that the Super XL is the best vacuum cleaner available, just that it’s better than the old vacuum.

The salesperson’s argument isn’t about which vacuum picked up the greater amount of dirt. He never actually assumes that the Super XL picked up more dirt. Instead, he argues that the Super XL is better because it picked up dirt that the old vacuum left behind.

The salesperson didn’t test the vacuums under the same conditions. He argues that the Super XL is better because it picked up dirt that the old vacuum missed on its first pass. But it’s possible that the Super XL might’ve left behind just as much dirt if it had been tested first.
