What magical machines have people invented because they are lazy?

Machine invented because of laziness? That's too much. Basically, machines were invented to replace manpower.

Automatic vacuum cleaner. Now the flat vacuum cleaner is placed directly on the floor, and it can run around the house to help you clean. Even if you don't have to take it to charge, it can run to the charging place by itself.

Express sorting robot. I don't know if everyone was noticed by the courier Huang Xiaomeng. Their birth can save people from the confusion of where to deliver express delivery, but its birth may also bring a lot of impact to the staff in the express delivery industry.

As we all know, as long as you throw clothes into the washing machine, pour laundry detergent or washing powder, and then press the switch, you don't have to wash your clothes yourself, which is really a great boon for lazy people.

Copier (printer) In ancient times, people saw their favorite books and suffered from financial difficulties, so they had to take notes by themselves. If you are too lazy to write now, just copy (print it out). You can copy any notes, but the price of copying is not necessarily cheap.

Refill. In ancient times, people used a writing brush, which needed polishing and was often dipped in ink. In modern times, people use pens, which are expensive and need to add ink frequently. The refills are different. A refill can be used for a long time, so don't worry about forgetting to bring ink.

Lighter. With a lighter, you don't have to bother to find wood to drill a fire or use matches.

Water pump. Labor and capital no longer have to worry about carrying water from low to high.

Cell phone. With a mobile phone, you can do what you want without running to meet or writing letters. If you don't want to go out to buy things, you can buy them with your fingers. You don't want to cook by yourself, but you can take them home with your fingers ... Of course, if you want to own these machines and enjoy the treatment of lazy people, you must have money first.
