Handwash and Vacuum - S2.E9

Maddie is cleaning up. She visits a factory where hand wash is made and uses her special camera to see inside a big vat to see the colour being mixed. Next, Maddie visits an appliance testing centre to find out how a vacuum cleaner works. She takes apart a vacuum cleaner to show us all the different parts and, using her special camera, show us how air gets sucked up through the machine so the filter can collect all the dirt and dust from our carpet!
