Aluko had previously played under Bruce at Birmingham City.
"When you've got a manager like Steve [Bruce] interested, you have to listen," Aluko told theBBC.
"He obviously already knew me from my time with Birmingham and he has retained a lot of the staff from his Birmingham days so hopefully that will help me settle down quickly.
"He spoke about how he wants the team to play and the way he wants me to play and I liked what I heard.
"To be honest, his ambition to take Hull into Premiership quickly was the biggest draw for me," added Aluko
"The main reason for moving here was their ambition to move into the Premiership and take the club forward quickly.
"I had a very positive meeting and calls with the manager and another meeting with the owner and they spoke about the desire to move into the Premiership - you can also see it with the players they have signed.
"Also from a football point of view it was important for me to hear I'll be an integral part of the team, and how Bruce saw me being used fit the role I was looking for, too.
"My immediate target is to really continue the good form I finished with last season and continue to score and create goals for the team in the push for promotion."

I saw the Nigerians jerking shots a few seconds into the clock.
Any coach in any sport who knows his team is going to lose will make sure they dont make it easy for the oponent. The Americans saw their chance to make olympic history and took it but the Africans didnt even realise.
