Same summary

The Roborock Saros 20 Sonic robot vacuum cleaner is primarily suitable for users who want to automate their daily household cleaning, especially where pets or multiple hard floor surfaces are present. The wet and dry cleaning capability and automatic station cleaning make routine removal of hair, dust and crumbs easier. Due to its advanced navigation, longer operating time and app support, it is useful in larger apartments or houses, where it reduces the need for manual intervention. It is important to note that a robot vacuum cleaner in a household with a lot of hair does not replace thorough manual cleaning, but effectively supplements it with regular, ongoing picking.
