anything called industrial means it's built better (with steel rather than plastic) and lasts longer and cleans better. Everything you use takes a little work on your part though.
Effective vacuuming can not only extend the life of carpet but also help to reduce dust, allergens and other issues related to carpeted areas. There are four types of vacuums: upright, tank, back pack, and specialty. The type machine you need will be determined by the type and amount of carpeting on your site. Another key factor will be degree of obstruction. In other words, how much stuff is in the building you are trying to clean.
I don't know about perfectly but usually the motor is stronger, the bar is larger so more area is covered with one swipe which is good for large carpeted areas but maybe not for home with closer arranged furniture. They tend to be a bit quieter as you don't want to scare the guests. If you are talking about the wet/dry type, be careful with the cleaning heads. Without the self propelled feature on a head, they are hard to push over carpeting.
