Trend Tracker: Submarine clean

With growing emphasis on outdoor living, iRobot has blown out its Verro Pool Cleaning Robot line.

The company now offers three robots in the line. Two new models, the Verro 100 ($399), designed to clean above-ground pools, and the Verro 500 ($999, pictured), designed for inground pools with heavier-duty scrubbing power, join the Verro 300 ($699) Pool Cleaning Robot, designed to thoroughly, but affordably, clean most inground pools.

The models are equipped with internal filtration systems that remove debris and part-icles for cleaner, healthier pools.
