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.
