The best feature for a house would be a self-cleaning device. I&#x27;m not talking only about automatic cleaners like the Roomba (which, as far as I&#x27;ve read, only work some of the time under some particular circumstances), but about the whole package: dust-cleaning robot, toilet-cleaning robot, dish-washer cleaning robot (we&#x27;re almost there for this thanks to the dish-washer machine itself), putting-things-back-in-place cleaning robot (books, pillows, toys, DVDs etc). Basically I&#x27;m thinking of something like Rosie from the Jetsons (<a href="https:&#x2F;&#x2F;www.google.ro&#x2F;search?q=rosie+jetsons&amp;client=firefox-a&amp;rls=org.mozilla:en-US:official&amp;channel=fflb&amp;biw=1280&amp;bih=613&amp;source=lnms&amp;tbm=isch&amp;sa=X&amp;ved=0ahUKEwiY7Lryi57LAhUhJ5oKHd-pDAAQ_AUIBygB" rel="nofollow">https:&#x2F;&#x2F;www.google.ro&#x2F;search?q=rosie+jetsons&amp;client=firefox-...</a>)
