**Does the iRobot Roomba Plus 678 Combo wash and dry its own mop?**

Yes. The station washes the mop itself, with water at 176 °F (80 °C). It then dries the mop with warm air.

**How high a threshold can the iRobot Roomba Plus 678 Combo climb?**

Thresholds up to 1.4 in (35 mm), the maker says. It has no climbing system for higher thresholds. Measure your own thresholds: the ones to a bathroom or balcony are often higher.

**Does the iRobot Roomba Plus 678 Combo fit under low furniture?**

The robot is 3.9 in (10 cm) tall, so it fits under furniture with at least 4 in of clearance.
