• Highlight: The Sandia Super Raven pairs a high-CFM 10-quart backpack design with a dedicated power head, so crews lift embedded dirt from carpet while still gliding across hard floors and upholstery.
• Best For: Janitorial crews and building-service contractors cleaning carpeted offices, schools, and multi-surface facilities where speed and back-friendly ergonomics matter.
• Expert Note: At roughly 67 dB the Raven is quiet enough for daytime cleaning, and Sandia backs the body with a lifetime warranty - a strong total-cost story for high-use accounts.
