-1 to having a robot wander through your place and things while you're not at home. As a commenter on this site you should be well aware that any computer security precautions are forfeit when a robot, capable of interfacing with your computer without even entering a password, is allowed physical access to your home.

Hire a maid.

Sure ask the roomba to iron clothes too and watch it while it goes up the walls your kids dirtied up. Check with people with kids on the verge of collapse - if you can afford it, its a godsend (in Asia, you probably can afford it atleast part-time).

Nobody said allowing access to the helper while nobody is around. Weekend help for a few hours is a thing. You can rest and relax while they are around. Just don't be dumb enough to tempt them by leaving a purse full of cash on the table. Even the best of the people can fall prey to a moment of weakness.

I gave it a try, with the only person I could trust (a family member) that was willing to work as a maid.

They quality of the work eventually went down. Fewer nooks and crannies were cleaner each passing week, there were also "cleaning mistakes" that happened that led to a roach infestation happening (or not being prevented from spreading), such as wet dishes inside the pantry.

I just moved to an smaller apartment and will just clean it myself, maybe will ask my GF to help me out.

Like in most other jobs, the quality of work does deteriorate. People get bored, take their employers for granted, cut corners and so on. In case of family, things are more complicated.

For domestic work, you usually can't offer them a career progression path to keep them interested. So the alternative is rotation. Though trust is definitely an issue, if your location has maid agencies that arrange for this kind of work, that aspect can be mostly addressed.
