Tennant Company Introduces Lithium-Ion Technology to AMR (Autonomous Mobile Robot) Floor Cleaning Machines

Today Tennant Company (NYSE: TNC), a world leader in designing, manufacturing, and marketing solutions to reinvent how the world cleans, announced the introduction of lithium-ion technology to their portfolio of AMR machines, including the T380AMR, T7AMR, and T16AMR. This new advanced battery technology provides added benefits to customers across the world in the cleaning industry. Tennant Company and partner Brain Corp, a leader in the robotics market, have engineered a portfolio of autonomous floor scrubbers and together they have deployed over 5,400 robotic scrubbers, representing the world’s largest fleet of autonomous floor 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 Balinski, Senior Vice President, Innovation and Technology, Tennant Company. “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”) that is ideal for retail stores, hospitals and education facilities. The T7AMR is a mid-size 26” scrubber ideal for mid-to-large spaces like larger retail stores and warehouse clubs, education, and some warehousing and logistic facilities, while the T16AMR is the first robotic scrubber designed specifically for industrial and warehouse spaces, with a 36” scrub path. Prior to the introduction of lithium-ion technology, Tennant’s AMR models were equipped with flooded lead-acid batteries to operate with estimated run times of up to 4 hours. Customers will now have the option to choose between flooded lead-acid and lithium-ion batteries in their AMR machines, though this new high-performance lithium-ion battery option has a run time between 5 and 6.5 hours, 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, FlagShip Facility Services, Inc. “Our T7AMR lithium-ion machine at the Raleigh-Durham Airport (RDU) 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.”
