I can provide some general information about Germany.
In Germany, there are typically regulations in place to maintain a certain level of peace and quiet on Sundays and public holidays. These regulations, known as "quiet hours" or "quiet days" (Ruhezeiten), vary depending on the specific region and local municipality.
During these quiet hours, which usually extend throughout the entire Sunday, noise-generating activities like vacuuming, using power tools, or engaging in loud activities may be restricted or prohibited. The purpose of these regulations is to ensure that people can enjoy a peaceful day of rest without disturbances.
It's important to note that the specific regulations may differ from one region or city to another, so it's best to check with your local authorities or look up the rules for your specific area to know if vacuuming or other noisy activities are allowed on Sundays. Additionally, some exceptions may apply to commercial establishments or certain situations.
Always being considerate of your neighbors and respecting local rules regarding quiet hours is a good practice, regardless of the country you are in.
