COMMERCIAL CLEANING ROBOT

COMMERCIAL CLEANING ROBOT

According to the Population Census conducted by the Statistics Bureau of Japan, the working-age population (ages 15-64) peaked at 87.26 million in 1995 and has been declining year by year, reaching 75.45 million in 2018.The proportion of the working-age population within the total population also peaked at 69.8% in 1992 and has continued to fall, reaching 59.7% in 2018. In the labor market, competition among companies to secure workers has intensified, leading to rising labor costs. Looking ahead, labor shortages are expected to worsen across all industries due to the retirement of the baby boomer generation, further driving up personnel expenses. To reduce the burden of cleaning operations in buildings and other facilities, we offer cleaning robots that support labor savings and operational efficiency.
