Don't Stick to One Direction! Pulling or Pushing, the EX40 18LX Makes Carpet Care Faster and Easier


Carpet cleaning is an essential part of maintaining a professional, welcoming space, and the Clarke EX40 18LX makes it easier and more effective than ever.

Unlike most carpet extractors that only clean when pulled backward, this machine is designed to work in both directions. Whether you’re pushing or pulling, it follows the same efficient three-step process: lay down solution, scrub the fibers, and extract moisture and dirt. That means less repositioning, better maneuverability, and a smoother cleaning experience in tight or high-traffic areas.

Built for performance and ease of use, the EX40 18LX features a floating brush head that automatically adjusts to the carpet for consistent deep cleaning, while the self-aligning vacuum shoe ensures maximum recovery, leaving carpets drier and ready for use sooner. The 12-gallon removable recovery tank reduces interruptions, so you can clean longer without stopping to empty and refill.

With its CRI Gold Certification, this extractor is proven to remove deep-seated dirt and allergens, helping to extend carpet life and improve indoor air quality. Whether you manage a facility or run a cleaning business, the Clarke EX40 18LX delivers powerful, professional results with every pass.
