Why the world has started to move to autonomous cleaning robots

Gist: Please note that a year ago, not a single robot was presented at the exhibition, and this year there are already 5: 2 Russian and 3 Chinese. Service robotics is experiencing explosive growth, the industry is growing at 48% per year, and Russia is in the "top 10" and ranks 9th in the number of service robot manufacturers.
All of this is due to:
- lack of line staff
- constant growth of their salaries
- lack of tools to check the quality of cleaning
Retail, which a year ago could condescendingly pay no more than 1 million for such a miracle, is now ready to give 2-3 million if only the robot was worthwhile.

The slamming of these very factors is leading to a point of singularity, I implore you to experience the moment when, in 2024, you will begin to encounter them everywhere. Robo-waiters, janitors, patrols and delivery men. Society has matured, technology has matured.
Yes, they're not perfect, we're constantly working on it. Soon they'll start seeing clumps of garbage and driving around them to avoid clogs. Soon they won't go to the section where the olive oil is broken and "trash" it all over the store. Soon robots will signal everything to humans with a picture and a message with the location.
Industry 4.0 is already there and there is no going back!
