The difference between the systems is the water delivery pressure and what is included with the system. The lowest cost add on and complete package use water pressure supplied by your garden hose, while the mid pressure system uses a residential 160 PSI water pump, and the top system uses a commercial grade 1,500 PSI pump and full filtration system.
Each system is intended for a certain use. The low pressure system works well for at home and occasional team/event use. The mid pressure is intended for more regular event or commercial use. The high pressure system is made for extended commercial use.
