iRobot's new pool-cleaning bots make me wish I had a pool. Both the Verro 300 and Verro 600 can vacuum up leaves, algae and bacteria from your pool, but what makes them extra cool is that they can do all of this while making sure the chemicals in your pool are distributed properly and water temperature is even. Not to mention they can climb up and down your pool's stairs.
The Verro 300 ($799) is best for harder surfaces (like concrete) while the Verro 600 ($1,199) is intended for tile or vinyl. Not a bad way to clean your pool.
