I will assume the other end of the attachment is not for cutting. It looks like a tool for emulsification. You can make sauces like mayonnaise using the attachment.
The comment of @steve-chambers confirms that it indeed is an emulsification tool.
I'm no electrician, but as Amps = Watts/Volts they had better be telling you the peak load, or you risk blowing fuses.
1500W on 240v = 6.25A.
1500W on 120v = 12.5A
This isn't like cheap hi-fi where they tell you the peak figure to make you think it's going to be louder ;)
