To sweep is to move quickly or to use a broom to move something such as dust. In sporting, especially American baseball, a team can sweep a series of games with an opponent by winning each one. The past tense and the past participle have the same spelling: swept.
Unlike leap and bless, this word does not have a less common variation. Sweeped is not a dictionary-recognized word. Some less reputable online dictionaries list it as an obsolete past tense of sweep. If so, it has been obsolete since at least the early 1800s.
Being swept up in something means to be along for the ride, partially unable to stop. A synonym is caught up.
