Robot vacuum cleaner iRobot Roomba 405 Combo Plus — bagless, 2 L dust capacity, 3 L water tank, 5000 mAh battery, 75 min runtime, black

The iRobot Roomba 405 Combo Plus is a round, black robot vacuum with integrated mopping functions designed for automated floor cleaning in homes and small offices. It combines vacuuming and wet mopping in a single device, offering a bagless 2 L dust container and a 3 L water tank. The system includes an AutoWash™ Dock that washes and dries the mop pads and automatically handles debris emptying while also serving as the charging base.

Advantages

The AutoWash™ Dock automates pad washing, drying and debris management, reducing manual maintenance. Navigation and mapping functions enable targeted and fully custom cleaning patterns, while Wi‑Fi connectivity and a user app allow remote control and scheduling. Compact dimensions and a neutral black finish help the unit integrate into typical home interiors.
