CRI Bronze Level Seal of Approval. CRI certified extraction for a deeper clean. The new AquaPLUS battery-powered walk-behind carpet extractors feature Advance's patented LIFT? low-moisture technology for a clean that is CRI certified.

AquaPLUS extractors with LIFT (Low-moisture, Indirect spray, Fast dry time, True cleaning) feature a patented spray system for faster dry times. The single-spray nozzle design eliminates streaking and the possibility of water overlap that can lead to delayed drying. The fast dry time of the AquaPLUS extractors make them ideal solutions for daytime cleaning. No other extractors will give you that certified deep clean and get people back on your carpets in less than 30 minutes.
