TennantT380AMR 400x275Tennant Company, which designs and manufactures systems for floor cleaning, has announced the introduction of lithium-ion technology to its portfolio of autonomous mobile robots, including the T380AMR, T7AMR, and T16AMR. Tennant and its partner, Brain Corp, have engineered a portfolio of autonomous floor scrubbers and deployed more than 5,400 robotic scrubbers.

“Throughout its 150-year history, Tennant Company has been dedicated to advancing the cleaning industry by relentlessly pursuing new technologies, and we are excited to continue this legacy with the addition of advanced lithium-ion battery technology to our autonomous machines,” said Barb Balinksi, senior vice president of innovation and technology at Tennant. “With longer run times and hassle-free maintenance, lithium-ion powered robotic scrubbers will help our customers increase their cleaning efficiency and optimize employee resources even more.”

The Tennant T380AMR is a compact floor scrubbing machine (20-inches) that is aimed at retail stores, hospitals and education facilities. The T7AMR is a midsize, 26-inch scrubber aimed at mid-to-large spaces, such as larger retail stores and warehouse clubs, education, and some warehousing and logistic facilities. The T16AMR is the first robotic scrubber designed specifically for industrial and warehouse spaces, with a 36-inch scrub path. Prior to the introduction of lithium-ion technology, Tennant’s AMR models were equipped with flooded lead-acid batteries, with estimated run times of up to four hours. The company said customers can now choose between the flooded lead-acid or lithium-ion batteries in their AMRs, with a runtime between five and 6.5 hours for the lithium-ion batteries, depending on the model.

“Every day we clean nearly 19 million square feet of space in airports throughout the U.S., which is why we bought a fleet of Tennant’s robotic scrubbers,” said Kevin Barton, vice president of operations at FlagShip Facility Services. “Our T7AMR lithium-ion machine at the Raleigh-Durham Airport has been an incredible game-changer. The autonomous floor scrubbers allow airport employees to have more time to use their skills on other important responsibilities. Plus, with lithium-ion batteries, the machines run longer and require less maintenance – saving us money and time while providing consistent cleaning performance and a better traveler experience.”

Tennant said features of the lithium-ion battery-powered models include:

  • Maximized productivity - up to 25% to 60% more cleaning time (depending on model), which lets employees be redeployed to other value-added tasks, such as stocking shelves, receiving goods, cleaning restrooms and assisting customers, staff or students.
  • Improved uptime – the systems allow for opportunity chagrin; customers can plug in the robotic scrubber at any time, even if the battery isn’t fully discharged. This offers increased uptime of the machine, without the risk of degrading the battery.
  • Simplified operations – a maintenance-free battery that does not require watering helps to simplify operator training and reduces the risk of operator misuse and abuse.
  • Reduced cost – eliminating battery watering and allowing opportunity charging delivers operational cost savings. With a 2,000 or more charge cycle lifespan, lithium-ion batteries reduce battery replacement costs.
  • Enhanced safety – No battery acid to worry about and no potentially harmful gases produced during charging, like lead-acid batteries pose.
  • Sustainability – Lithium-ion batteries help eliminate reliance on non-renewable natural resources, while reducing carbon emissions.
