Niall McGinn two goals topped and tailed a superb display by the Dons, with Calvin Zola and Michael Hector also scoring to ensure McInnes' side won their fourth straight with a fourth clean sheet.
"You've got to be pleased. It's another clean sheet, four goals at home, it doesn't get much better than that," McInnes told Sky Sports.
"Partick made it difficult, they've got a great record on the road, they play the type of football that can frustrate a home crowd and you don't always get it your own way, but we restricted them to very little.
"We were a little bit sloppy at times but you've got to enjoy winning 4-0. I've just told the players that the game is tough enough - it's hard when you lose, frustrating when you draw games - so when you win games you've got to enjoy it. We were not at our best, but we showed enough quality to get the job done.
"There is still work to be done. It's an easy thing to say but we are nowhere near where I think we can be. We've got to keep striving for that improvement and the players are honest enough that they want to keep improving.
"We're just into November, there is a long, long way to go, but we're obviously pleased and the quality of the goals was fantastic as well."
Man-of-the-match McGinn added: "The lads were fantastic all over the pitch.
"Partick play the football the right way, its nice to play against teams like that, but thankfully we got the three points.
"We have improved on our consistency, we're winning games on the bounce, the confidence is growing and we've just got to keep that going.
"We're not getting carried away, but we're in a good place and we've got to kick on and look forward to Saturday."
Partick boss Alan Archibald admitted the defeat was a bitter pill to swallow, adding: "It's a sore one to take. It's not nice to lose any game 4-0, and it's a bitter pill to swallow.
"I think Aberdeen were more clinical than us and made better decisions than us on the night. We kicked on after the last time we were beaten by Aberdeen and we'll need to do that again after tonight."
Archibald felt his side need to learn lessons from the defeat, adding: "We've learned lessons in terms of giving the other team too much respect and too much space."
