In 1888, the mothers
and any kids old enough to help had essentially full-time jobs with the housework. And mandatory education stopped much younger than today, IIRC from 10 to 14 depending on the country (assuming they had mandatory education at all, which some didn't), so they had more time than you may expect for helping with the household.
There were mechanical washing machines and vaccum cleaners back then, even before electricity, but even that was all harder work than now.
