The salesperson said politely, "Certainly. For home use, please look at this row. These Kitchen Machines are all designed for household use, so their capacities are considerably smaller than commercial models."
"May I ask how many people usually use it in your household? Different numbers of people require different capacities. Please look at this stainless steel bowl. It is for holding flour, and these bowls come in different sizes: 3.5 liters, 5.5 liters, 6.5 liters, and 7.5 liters. These are all household models."
Su Chen said, "There are six people in our family."
"For six people, I recommend the 7.5-liter one. That way, you can make much more at a time. Also, a 7.5-liter Kitchen Machine has a much more powerful motor, so it can handle a larger batch of dough at once."
Su Chen nodded. "Mm, sounds good. Let's get the 7.5-liter one."
Yan Bingxue looked at the 7.5-liter stainless steel bowl and said, "This bowl is huge!"
The salesperson said, "Although this stainless steel bowl looks very large, there is still a limit to how much you can put inside. You cannot exceed the marked line. If you do, mixing will become difficult, and it may not even mix properly. When you take it home, be sure to pay attention to the markings inside the bowl."
Su Chen picked up the stainless steel bowl and checked the markings inside. They were roughly at the three-quarter point.
He nodded and asked, "How powerful is the motor?"
The salesperson said, "The 7.5-liter Kitchen Machines come with either DC motors or AC motors. AC motors generally have lower wattage, but a 300-watt AC motor is equivalent to a 1,000-watt DC motor."
Yan Bingxue said, "So AC motors use less electricity than DC motors, and they seem better too."
