TM easily cleans better than a portable, it has more power, so why people have voted the same is beyond me.
Remember when we use portables with 70 psi pumps and single vacs, now its 135+ and twin vacs these portables clean better, so surely TM will clean better as they have more power?
But then I suppoe that depends on what is a superior clean. I assume more dirt removed and dryer carpet. TM wins
