In the past fifty years the invention of{{U}} (1) {{/U}}devices and appliances has made housework much easier. Among these devices and appliances are{{U}} (2) {{/U}}cleaners, electric irons, washing machines, and some others. Probably the most important piece of{{U}} (3) {{/U}}equipment which has been widely used in the last twenty years is the{{U}} (4) {{/U}}. Washing up by hand is not only{{U}} (5) {{/U}}but also extremely boring. Dishwashers are of different sizes and{{U}} (6) {{/U}}. Their capacity ranges from six to{{U}} (7) {{/U}}place-settings.

Remember that dishwasher can be quite{{U}} (19) {{/U}}, so you may prefer to use the machine just once a day, preferably{{U}} (20) {{/U}}thing at night.
