I think it'll be more capable appliances at first.
Like a lawn mowing device that also spots weeds and can spray them.
Next iteration has arms to rip weeds out of the garden.
Next has attachments so you can direct it to do pruning.
Next it can figure out the pruning itself and move the outcome into the woodchipper.
And so on and so on.
It's not going to be one day a humanoid robot comes into the house and does everything.
That's available as a tractor-pulled implement for farms. Deere and some others make such things.
Set the boundaries and let it go at midnight to quietly wander the lawn and spray the weeds. If it could spray into nearby garden beds too, so much the better.
Being infinitely patient it could apply small targeted doses to only what you don't want. A human doing it often doesn't have the patience or accuracy.
Which doesn't mean I disagree with you. I also think that this progression is the most likely. But it implies we're decades away from broad adoption rates.
Think fifty years to hit mass adoption, not five. (Because that much more closely aligns with other structurally disruptive tech like automobiles or computers) Which is definitely not the story being pitched to investors at the moment.
Products that start life as "for the rich, first adopters" and work their way down the economic classes are a thing. Whether it is the thing in this case I don't know.

I would think that what is pitched is what investors want to hear....
