And, we're not kidding!
When asked what he would take away from his experience, the Italian pug lover said: "I've learnt how to use the washing machine!"
Speaking at a press conference ahead of The X Factor final on Saturday night, Mel B's remaining act Andrea joked he can now clean his clothes properly.
"I've realised it's not so good to wear dirty underwear now," he added. "So I'm very glad!"
Hmm probably for the best, Andrea!
Before revealing his new found domestic prowess, the X Factor hopeful did say that his experience had helped him to find his confidence - especially after leaving behind his family in Rome to compete on the show.
He said: "This is an amazing achievement for me. I've learnt how to be strong and face things alone, in another country, without my friends and family. And, I've learnt to be the best I can be under pressure."
But, not without the help of his mentor Mel, speaking about the Spice Girl, Andrea claimed she had been "amazing" throughout the competition.
"I can say I've found a friend and a mentor," he gushed. "She has done everything to make me feel at home."
Ahead of the final, Andrea - accompanied by X Factor host Dermot O'Leary - has been out in the capital in the hope to drum up votes for this weekend.
Unable to return home like his fellow finalists, Andrea instead took to the stage in London's Leicester Square and was treated to his very own pug party.
Not a bad alternative, hey?!
But, while he has been meeting his fans, Mel has been resting at home after being struck down by illness.
And, fears are growing that she may not even be able to make the final, if she does not get better in time.
A spokesperson for ITV has said: "There is a chance Mel she won't make it, absolutely."
Fingers crossed she'll be able to join Andrea on the night as he battles it out with fellow finalists Fleur East and Ben Haenow.
The X Factor final begins this Saturday 13 December at 8.30pm on ITV.
