This prototype works with the return of filtration but its concept makes it possible to manufacture suction robots, propelled by a water jet, which function either through forcing back, or with a booster pump, or autonomously with a 12-volt embarked pump.

Advantages:

• Filter included in the equipment, direct vacuum through the embarked pump or the Venturi system for the models with external pump (filtration or booster pump).
  
• No risk of the robot being blocked in corners, by the ladder, a creased liner, the outlet, the stairs...
  
• No adjustment needed from end-users.
  
• Simple, reliable, robust manufacture (only one moving part, no timer or reverse gear valve).
  
• High speed: see video.
  
• The concept makes it possible to design different products (hydraulic and electrical)
