Shark PowerDetect with NeverTouch Pro Base

It auto-empties and refills the robot's water, though the dock does not clean its own wash tray, which needs occasional wiping.

The robot is 4.1 inches tall, so it fits under taller furniture but may not clear very low sofas or cabinets.

It clears obstacles up to 38 mm, so it handles taller thresholds and transition strips than many robots.

It covers about 622 sq ft per run, so it suits small spaces and recharges and resumes for anything larger.
