    • ProSeries Generator- while both models can be used with ThermaSol's add-on features, most reviewers prefer the ProSeries. The AF Series comes with the Auto PowerFlush™ system, which is an inner tank cleaning system that some consumers may not want due to its impact on water usage.

    This version is also equipped with SmartSteam feature. This technology allows for precise control of steam volume to maintain a desired temperature while conserving energy and providing a peaceful and comfortable experience. SmartSteam is exclusive to the ProSeries model.

    • Noise and hot air but not much steam
    • Some Amazon reviews about their warranty is worrisome
