Did you hire them for maids or for...accessorial services? Because you've mentioned two factors (20s and energetic) which don't necessarily correspond to cleaning abilities.
"Just someone to keep my house clean, fix my meals, then go away..." For about 40 years my wife and I have cleaning people come in every four weeks (13 times a year). My wife is happy with that arraignment. When I first heard this song I was blown away. The full orchestration (not like St. Pepper's). How he used the french horns and chimes...Especially the chimes. You can't put chimes in rock and roll!!
Make sure they are an outside contractor!! They have a license and insurance/bond in the city you live in. In one of my audits (30 years ago), the first question they asked was do "you have a maid"!! Easy picking for the IRS...
Hopefully they dusted off his clown shoes he's going to need them to dance around all the childish stuff he's been up to this year.
