Q: What size is the motor (watts)?

No wattage is shown anywhere on the box, manual, or appliance. But on the appliance, it says 1.8 amps. As a rule of thumb, watts = amps x volts, so the wattage should be approximately 200.

Q: Do you have to continuously hold the button down for it to work, or does it have an on/off switch?
