Do butlers and maids vacuum?

I had a glitch when I was playing last night. I have Bust the Dust but have the gameplay turned off in game options. My sim hired a maid and he showed up and started vacuuming the bathroom (there was water on the floor). After that dust bunnies started appearing. Again, I have bust the dust turned off. The maid only vacuumed that one time. I've rotated to a different household without a maid. Curious to see what happens if I hire a maid again.
