Which household sweeper is easy to use?

Want a clean and tidy home environment, but have to drag the tired body to lie on the sofa, it is the so-called heart is spare but not enough. In fact, we are not at a loss in this situation, but whether we can find a good helper. Some people say that with my current economic source, I can't afford to work in hours. But I want to say, who says that cleaning work must be done by people? We can hire smart "robots", which are not only hard-working, but also highly efficient.
