Tennant ec-H2O NanoClean

The ec-H2O NanoClean offers the same great benefits of the first generation and now cleans better by cleaning more soils in more applications.

This electrically charged, converted water is created by an on-board e-cell that generates millions of very tiny microscopic bubbles known as nanobubbles that promote the cleaning efficacy of the water solution.

ec-H2O NanoClean™ technology is available on T300, T500 and 5680 walk behind scrubber-dryers and on the T7+ micro rider floor scrubber.

Reduced Cost To Clean 

Cleaning with water only and no chemical brings significant savings in detergent costs and labour savings through increased productivity.

Scrubbing with ec-H2O NanoClean™ effectively removes typical daily soils as well as more stubborn soils like food greases, road salt and more, without leaving detergent residue.

Health & Safety

ec-H2O NanoClean™ is certified by the NFSI to improve floor traction and reduce the risk of slip and fall accidents. Additionally, NSF registration ensures the technology is safe to use in food and beverage handling environments.


Since only water is used, ec-H2O NanoClean™ reduces the impact of cleaning operations on the environment in seven key categories according to a third-party study by EcoForm.

Superior Cleaning Technology

  • Since 2008, ec-H2O™ technology has become the standard in detergent free floor cleaning.
  • Tennant Company has shipped over 65,000 machines, to over 7,500 customers at 29,000 locations around the world.
  • ec-H2O NanoClean™ will continue the trend of Tennant Company innovation by offering even better performance with the same cost saving benefits as the original technology.

Sound Science

Traditional floor scrubbers clean through three mechanisms on the floor:
  • Hydration by the water
  •  Mechanical scrubbing action by the brushes or pads
  •  Cleaning effects of any detergent added to the solution.
Scrubber-Dryers equipped with the ec-H2O NanoClean™ technology still use the power of hydration and mechanical action, but instead of an added detergent, relies on electrically converted water to promote the cleaning power of the solution.
This converted water is created by an on board e-cell and contains millions of very tiny microscopic bubbles known as nanobubbles.

Working with university scientists around the world, Tennant Company has established that it is these nanobubbles that provide the cleaning power in ec-H2O NanoClean™

Real Results

ec-H2O NanoClean™ has shown that the scrubber dryer is able to clean a wide variety of soils including typical daily soils as well as more stubborn soils like food greases, road salt, and more.

In addition to the outstanding scrubber dryer performance, ec-H2O NanoClean™ can create real savings by:
  • Reducing the need to purchase floor cleaning chemicals.
  • Increase productivity by allowing operators to clean up to three times longer before the need to drain and refill the scrubber dryewr which can be a significant source of downtime.
  • Reduce other costs such as water supply and waste as well as costs associated with the purchasing and storing of conventional detergents.
