Abstract
A battery operated portable hydromassage appliance including control circuitry which senses the voltage level of the battery. When the battery voltage is below a predetermined level, the control circuitry automatically shuts the unit off so that the battery may be recharged before irreversible damage to the battery occurs. Also included is a low frequency oscillator which in combination with the low battery detector applies a pulsing input to the motor to turn the pump motor on and off and accordingly create a pulsing effect at the hydromassage appliance output.
