"Doop" achieved success in several countries, including the United Kingdom, where it spent three weeks atop the UK Singles Chart.

"[3] Tom Ewing of Freaky Trigger noted that "while it's never anything more than 'the Charleston with a donk on it', it's also far more generous with its hooks and energy than one-line descriptions suggest.

"[6] Andy Beevers from Music Week rated the song four out of five, adding that "this unlikely combination of Nineties house sounds and Twenties Charleston/ragtime rhythms" has been "creating dancefloor mayhem ever since."

"[7] Sylvia Patterson from Smash Hits gave "Doop" three out of five, writing, "Ludicrously catchy mickey-mouse rave-up sensation featuring someone playing the spoons, someone on the party blower with a feather on the end of it and Rolf Harris on the stylophone.

The single entered the top-10 of the charts in Finland (3), Germany (6), Hungary,[11] Ireland (2), Norway, Poland,[11] Spain (3), and Switzerland (2), as well as on the Eurochart Hot 100, where the song peaked at number three.
