Our Verdict

Shark UltraCyclone Pet Pro+ [CH951, CH964AMZ]

iRobot H1

The Shark UltraCyclone Pet Pro+ is better than the iRobot H1. The Shark is easier to maintain, incurs fewer recurring costs, is slightly lighter, and delivers superior cleaning performance on bare floors as well as low- and high-pile carpets. Meanwhile, the iRobot lasts much longer in its least powerful suction mode, though that can vary in the real world. It also comes with a wall-mount rack station, making it a little easier to store.
