I see that only disinfectants Flexcare has with them.
With other (Elite, Essence, Advance, Xtreme), you must purchase it separately right?

So is there anything else you can say about them?

In addition to the disinfectant, this model is smaller, lighter, quieter, less vibration and more energy efficient than all others. It also has a lithium ion battery instead of a rechargeable nickel-cadmium batteries, more environmentally friendly. Those are the major differences.
