The bidet attachment requires no electricity or batteries to run. You just turn or press the knob to get the washing function, which is simple and easy to operate.
The bidet seat needs to be connected to a power supply, and it often has a button-heavy operation panel on one side, or a remote control with more buttons. This undoubtedly increases the difficulty of operation for the elderly and children. If it is wrong operated, it may not be able to achieve the water spray, heating, deodorization and other effects, and may even cause the circuit failure of the product itself.
