a children's book- robot in family as a domestic help

I think what you're talking about is:

The Type One Super Robot by Alison Prince.

The kid's uncle names the robot Manders because he does everything a man does.

If not, maybe you're talking about the Richie Rich comics, where Irona is his robomaid's name. They've got a whole squad of robo-helpers, if I remember correectly, though.

Oh! Or the Jetsons. Family living in the future; their maid's name is Rosie. Although that's a TV show, there were comic-book versions of that show.

I read the same (?) book a few years after you between 2005-2010.

I believe the book you're looking for is Eager, by Helen Fox

Here's a photo of the cover.

It's the end of the 21st century where technocrats rule and robots take care of humans’ every need. Your house watches you, knows your secrets, and talks to you. And your closest friend can be—a machine?

Gavin Bell and his teenage sister Fleur come from a middle-class family. Their much-loved, old-fashioned robot, Grumps, is running down and can’t be repaired, so a scientist friend loans them EGR3, an experimental new robot to help Grumps. EGR3, known as Eager, learns from his experiences, as a child would. He feels emotions—wonder, excitement, and loss. When the ultra high-tech, eerily human BDC4 robots begin to behave suspiciously, Eager and the Bells are drawn into a great adventure that is sometimes dark and often humorous. As Eager’s extraordinary abilities are tested to the limit, he will try to find the answer to this question: What does it mean to be alive?
