• Price:
  This is the first one that you probably need to take into consideration.
  On Dupray official site dupray.com, the listed retail price of the HOME is $249.98, NEAT is $319.99, ONE is $699.00, ONE PLUS is $899.00, Tosca is $1,297.00, Hill Injection is $2,497.00.
  So, this is a huge difference between them. If you have limited budget, then the HOME and NEAT are more proper choices; if you want better results and better quality, have a look at the Hill Injection, however, it is much more expensive.
• The second big difference between them is the ability of refilling while in use.
  The ONE PLUS and Hill Injection have Continuous Steam Technology, they were designed with a two-tank system which means the water tank is not under pressure, and you can refill it at any time, this greatly reduce downtime. The others do not have this feature, they have cleaning time limit with one fill up; when steam runs out and you would like to continue using the steam cleaner, you have to turn off the machine to let the boiler cool down like 10 to 20 minutes, refill with water, wait for another 10 minutes to allow the machine to generate steam. This process does cost you time. As for the models that have no Continuous Steam Technology, the HOME runs up to 40 minutes per fill up, the NEAT and ONE run up to 50 minutes whereas the Tosca runs up to 90 minutes due to its much larger boiler.

• Hose Design:
  The HOME and NEAT have a built-in hose whereas the others have detachable hose for more convenient cleaning up, storage, and steam pressure adjusting.
• Adjustable Steam:
  The NEAT does not have a steam adjustment wherever others allow you to adjust the steam pressure to fit different cleaning needs.
• Cord Length:
