Alex, re; "sweeper"
In the USA Midwest, and parts of the appalatian mountain areas and into the mid Atlantic region, they say sweeper for vacuum like you say hoover, or "hoovering" regardless of the brand.
Also "red up the house" for clean the house.
In New Jersey, Chocolate is pronounced Cha^colate, with a short c sound.
Our southerners say their dialect is directly adapted from Britain, which there is just no way it is at all.
