The P|Flux series gets a host of exciting new upgrades including an auto-cleaning feature standard on all models in this line. The auto-clean conveniently activates every 10 minutes, or you can simply activate from the sleek redesigned remote. Overfilling the drum is a thing of the past, thanks to the super-sized 46 gallon octagonal drum (P|Flux 2 and 3), and a bright LED light illuminating the drum on all P|Flux models. Plus, LED and audio warning lets you know when the drum is full features that are now standard in this line.
