Smorobot Tank C1 robotic pool cleaner review: Short of greatness

This uniquely designed robot covers the basics of pool cleaning but not much else, and it struggles with some tasks. Smorobot is a new brand to us, but the manufacturer has seven different robotic pool cleaners already under its belt, including this one, the Smorobot Tank C1. As the name implies, this robot is intended to be a workhorse in the pool, promising a 150-minute runtime and maximum coverage of 2,500 square feet. The robot measures roughly 12 x 17 x 15 (HxWxL) inches in size and weighs 18 pounds. It's powered by a 7800mAh battery, which is on the small side for a robot of this size; but in my testing, it was invariably able to exceed its specified running time of 150 minutes, usually by about half an hour.
