机器人选的是Roomba——一个圆盘状的自动真空清洁机，还有四个像人类的机器人——它们具备的人类特点多少程度不同。
The robots were the Roomba, a disc-shaped autonomous vacuum cleaner, and four anthropoid machines of varying degrees of humanness.
也是在那天，我将家里看了个遍，找出自己拥有的东西——一把拖把，一台真空吸尘器以及一些洗涤剂——然后决定开始我们自己的清洁业务。
And that was the day I looked around my house and saw what I had – a mop, a vacuum leaner and some cleaning fluids – and I decided to start our own cleaning business.
比如购买吸尘器(和它保持工作良好的维修费用)，加上购买那些日常清洁必须物诸如真空袋，海绵，纸巾和清洁剂的额外费用。
There's the expense of buying a vacuum cleaner (and keeping it in good repair), plus the extra cost of purchasing cleaning must-haves like vacuum bags, sponges, paper towels and cleansers.
