Leading Institutions That Select Centaur Machines

The Best Vacuum I Have EVER Owned

I wanted to introduce you to BLUE BOY! She is the best vacuum I have EVER owned. Thanks @nwrpainting for the recommendation and thank you @centaurfloormachines for creating a vacuum that actually works and actually sucks 😉😉 (Instragram)

—Jennifer Carr, Jennifer Carr Painting

The Vacuum Worked Flawlessly!

“So I just wanted to let you know I received the Falcon-5 and put it to work right away. I removed the popcorn ceiling in an entire house and filled 2 garbage bags full of drywall dust.

The vacuum worked flawlessly! The HEPA filter was spotless and the bag pre filters that you gave me were very important in this process.

Centaur switched the 10-foot hose to a 20-foot hose for me and they replaced the white filter bag with the grey drywall dust one. This level of customer service is hard to come by these days and because of that I have recommended the vacuums to a bunch of other painting companies in the US.

Thank you so much for Coordinating all of this and providing such amazing service and product.

Hats off to you for being a needle in the haystack in this day and age.”

—Nick Rochacewich, NWR Painting Inc.
