Tennant announces specifications of its first purpose-built AMR floor scrubber

Floor-cleaning vehicle provider Tennant Company recently unveiled the full specification and capabilities of its X4 ROVR autonomous floor scrubber. The X4 ROVR is Tennant’s first purpose-built autonomous floor cleaning machine and fourth robotic scrubber in its product line.

The X4 ROVR’s autonomous operation technology is provided by robotic navigation and fleet management systems provider Brain Corp’s BrainOS robotics platform.

Brain Corp recently entered an exclusive partnership to supply automation technology for Tennant’s floor-cleaning robots.

The new Tennant X4 ROVR robotic scrubber is available to order immediately.

Engineered from the ground up for autonomous operation, Tennant said the X4 ROVR robotic scrubber delivers unparalleled cleaning performance and adaptability across numerous commercial environments, including retail, healthcare, education, as well as multiple building service contractor (BSC) applications where optimized productivity is crucial to success.

“The new X4 ROVR robotic scrubber has been meticulously developed to help cleaning teams free up bandwidth and, as a result, improve their efficiency,” said Dave Huml, President and CEO of Tennant Company. “It aims to empower businesses to deploy autonomous cleaning that requires minimal human interaction, truly freeing up employees for higher value tasks.”

Purpose built with productivity in mind, Tennant said the X4 ROVR autonomous floor scrubber features a dual disk scrub path, a high-performance vacuum system, and technology that adapts seamlessly to various hard floor environments.

It is equipped with a 10-gallon solution tank and delivers a cleaning productivity rate of up to 20,000 square feet on a single full tank. It is also supported by a lithium-ion battery that powers up to two and a half hours of continuous cleaning when fully charged.

The X4 ROVR’s computer vision technology and compact dimensions give the autonomous mobile robot (AMR) the ability to navigate narrow and congested spaces.

“With Brain Corp’s next-generation software powering a step-change in navigation capabilities, our design team focused on delivering a robotic cleaning machine with improved maneuverability, durability, reliability and productivity,” said Huml.

Users of the X4 ROVR robotic scrubber can stay connected to their autonomous cleaning operations by using BrainOS operations management tools, including a mobile app, email reports, and monitoring portal. Tennant said this suite of tools empowers a digital approach to monitoring, reporting, and enhancing cleaning performance with transparent proof-of-work insights for operations.

“The X4 ROVR comes with the tools and services needed to transform how cleaning teams operate, making their work more efficient and reliable than ever before,” said David Pinn, CEO of Brain Corp.

Tennant said it will also leverage its customer success team to support robots throughout their lifetime, with the aim of making each a reliable, valued member of their customers’ cleaning programs.

Brain Corp also offers an inventory-scanning add-on for Tennant’s floor scrubbers, enabling multifunction mobile robot operations.
