“ist gefegt” vs. “hat gefegt”

Question

I’m assuming the following translations are reasonable:

Sie fegte über die Bühne. → She swept across the stage.

Sie fegte die Bühne. → She swept the stage.

The conjugation in an online resource gives these two alternatives: ist gefegt and hat gefegt.

Would I be right in surmising that the first alternative applies to the first usage above and the second to the second? Thus:

Sie ist über die Bühne gefegt.

Sie hat die Bühne gefegt.

Answer 1

Ja, die Vermutung ist absolut richtig.

Sie ist über die Bühne gefegt.

means acting,

Sie hat die Bühne gefegt.

means to do the cleaning.

Answer 2

Your surmise seems right to me.

One of the cases where one should use "sein" for perfect tense is:

• With action verbs that denote a change of place and not necessarily just movement, e.g. tanzen

So, in your example, the verb "fegen" is conjugated in perfect tense using "sein" when it denotes a change of place or movement. For the other usage it's conjugated using "haben":

Sie ist über die Bühne gefegt: She swept across the stage.

Sie hat die Bühne gefegt: She swept the stage.

Also, reading an article about "Sein" and "Haben" would be helpful.

Answer 3

As a native speaker, my first thought was: you're right. "Sie fegte über die Bühne." translates as "She ran across the stage.", which describes a movement like "Sie ist gelaufen" ("She walked"). Whereas the second "Sie fegte die Bühne" means - as you wrote - "She swept the stage", which is more of a crafting act like "She painted the stage" ("Sie hat die Bühne gestrichen").
