Terry Zucker has invented the best vacuum cleaner in the world - just turn it on and cleans up all by itself. Every household in the UK has one, including the prime minister's. St Hope's have even got some. Mr Flatley has won a holiday, but Mrs King will not allow him to abandon his teaching duties. She also needs him on hand to help clear up St Hope's. Mr Flatley has other ideas - he is going on this trip no matter what Mrs King says. He enlists his identical twin brother, Dave, to come and pretend to be him. Dave may look like Kenneth, but he's a very different fish. He is cocky, lazy and isn't afraid to put Mrs King in her place, which she finds very attractive indeed, much to Dave's annoyance. Not only is the school filthy, but HQ is also covered in dirt. Frank hasn't vacuumed in months. Luckily Carrie brings down a Zucker - the world-famous vacuum. Frank is a little annoyed that Carrie has brought an unauthorised object into HQ, but agrees to allow the little machine to go about its business. Little do they know that the Zucker is recording everything it sees and transmitting it back to its owner Terry Zucker. The spies are given a mission - the prime minister has been robbed! A golden statue, which he was due to give as a present to the Governor of Mumbai at an official presentation, has been stolen. The team uncover the culprit and, while trying to capture him, find themselves in danger of being sucked into a black hole. How will the spies get out of this one?
