Out of curiosity, I searched the pet vacuum mentioned in the first example, and found it on amazon [0]. Just like Bing says, it is a corded model with a 16 feet cord, and searching the reviews for "noise" shows that many people think that it is too loud. At least in this case, it seems that Bing got it right.
