It's way less about the time of doing the thing, and much more about the mental overhead of having to remember to do the thing. And needing to do the thing at very inconvenient times because I forgot to do the thing or lacked motivation when I should have done the thing.
This goes for any recurring chore in my life. I love to garden, but watering plants is hell to me after the novelty wears off. I fixed this by installing an automated irrigation system. I get to do the fun bits mostly on my schedule to wind down when I feel like it (pruning, harvesting, staring at plants) and didn't sign myself up for yet another daily chore to do.
My wife is the opposite. She thrives on "chores" or routine simple items like this. She absolutely loves doing laundry to an absurd degree - kind of a zen moment in the middle of her day she can quickly spend 10 minutes here and there to get done. Same goes for cooking. I enjoy planning and creating elaborate meals I've dialed into "perfection" but take me an entire Saturday to accomplish a few times a year. She loves spending 30 minutes in the kitchen most nights to wind down after work - but really hates "big" projects of any type.
I imagine it has a lot to do with executive function. I enjoy large one-off projects (e.g. designing and installing an over the top totally overkill irrigation system) that are eventually "done" but fall apart on repetitive simple things that never end and just reset to be done X hours all over again. I like to have my "mental slate" clean when I wake up for the day, and I find I accomplish far more when I can configure my life in such a way.
As such, this robot as-is would be somewhat useless to me as I'd have to remember to hang up the clothes or walk them up the stairs to put away or whatever even with it. I'd get very little advantage for the spend.
