Cleaning duo Richard and Brennan take on some of Britain's filthiest and most cluttered homes. They begin with Lincolnshire single mum, Sam, who has dedicated her life to caring for her disabled daughter, leaving no time for cleaning.

Extreme cleaners Richard and Brennan travel to Gateshead to help 40-year-old sci-fi collector Abi, whose massive horde of toys, posters and films has completely taken over her home.
