A new range of robotic cleaning devices introduces advanced features for easier home maintenance. One model combines vacuuming and wet floor cleaning, using an extendable rotating roller to clean along walls and reach edges more effectively. Its brush design helps reduce hair buildup, while powerful suction removes dust and debris from floors. Smart stain detection allows the robot to spray water directly onto dirty areas and clean them with repeated passes. A multifunctional docking station also helps reduce the need for frequent user intervention. Retails for $1399.25
