Solar-Breeze NX, a solar-powered robotic pool cleaner funded through Kickstarter, now is available. It stores extra power in a rechargeable battery. Solar-Breeze moves across the water, removing dirt, debris, pollen and other contaminants. The “smart” cleaner knows to move toward sunny areas when the battery is running low and to reverse to avoid getting stuck in one place. Contact: Solar Pool Technologies, (623) 582-2825;
