Overview

The Kärcher KIRA B 50 is an autonomous scrubber dryer robot designed for efficient and consistent floor cleaning in medium to large areas. It combines the functionality of a scrubber dryer with intelligent autonomous navigation, using a roller brush head that pre-sweeps and scrubs in one step, plus an integrated side brush for edge cleaning. The robot features high-performance sensors with 360° detection for reliable navigation, obstacle avoidance, and safety certification per IEC 63327 for use in high-traffic public areas. Intuitive touch display setup, optional docking station for fully autonomous operation (refilling water, emptying dirty water, rinsing tank, charging), and a web portal for remote monitoring and cleaning reports are key features.
