Oral irrigator with variable output fluid characteristics

An oral irrigator comprising:

• a reservoir;
• a tip in fluid communication with the reservoir;
• a pump in fluid communication with the tip and the reservoir, wherein the pump pumps fluid from the reservoir to the tip;
• a motor connected to the pump, wherein the motor drives the pump;
• and
• a control module electrically coupled to the motor to vary an output of the motor, wherein:
• during a normal mode, the control module drives the motor to output a normal fluid pulse rate, a normal flow rate, and a normal fluid pressure as the fluid exits the tip;
• during a massage mode, the control module drives the motor to output a massage fluid pulse rate, a massage flow rate, and a massage fluid pressure as the fluid exits the tip, wherein the massage fluid pulse rate is lower than the normal fluid pulse rate, and the massage fluid pressure is lower than the normal fluid pressure;
• during the normal mode the control module drives the motor at a first voltage magnitude and a first voltage frequency;
• and
• during the massage mode the control module drives the motor at a second voltage magnitude and a second voltage frequency.
