Tennant: X4 and X6 ROVR Autonomous Floor Scrubbers
Compare Tennant X4 and X6 ROVR floor scrubbers, BrainOS software and optional charging, using a dated Denver Public Schools reference and practical deployment checks.
Company and robotics focus
Tennant Company, founded in 1870 and headquartered in Eden Prairie, Minnesota, supplies floor-cleaning equipment including autonomous scrubbers. Its X4 ROVR and X6 ROVR products use Brain Corp's BrainOS technology. A purchase should cover the cleaning machine, the applicable software and a supported operating process; the presence of navigation software alone does not establish the results at a particular site.

X4 ROVR for smaller spaces
The current X4 ROVR product page describes a compact autonomous scrubber with a 500 mm cleaning path for small to medium spaces. It also presents SelfPath AI and BrainOS Clean 2.0 capabilities. Confirm the software release, subscription and update eligibility attached to the offered machine; features on a current product page should not automatically be attributed to every earlier installation.

X6 ROVR and charging options
Tennant announced X6 ROVR on 15 April 2025 for larger and more complex cleaning environments. The current product page lists a 650 mm cleaning path and 95-litre tanks. Its optional XC1 station provides automatic charging. The reviewed sources do not establish automatic fresh-water filling or dirty-water drainage for that station, so those functions should not be included by assumption. X6 ROVR specifications.
Denver Public Schools reference
A Tennant case study covering 2021–2024 reports that Denver Public Schools deployed 20 T380AMR machines and three X4 ROVR scrubbers, with use in hallways, gyms and cafeterias. This is a dated supplier-published account of two product generations. The fleet count belongs to that reporting period and is not presented as the district's current total. The case provides deployment context, not a guaranteed productivity result for another school. Denver Public Schools case study.
Workflow and site requirements
Map cleaning zones, floor finishes, narrow passages, pedestrian crossings and storage locations before selecting a machine. Determine who prepares the route, handles water and consumables, checks brushes and squeegees, and recovers a stopped run. Test the real transition between autonomous cleaning and the remaining manual work, including edges, stairs and areas excluded from the robot's route.
Software, data and support
Request a demonstration of route creation, incomplete-task alerts, report exports and user permissions for the quoted configuration. Clarify network requirements, data retention, remote-support access and the behavior during a connection outage. Record the software renewal price, update policy, local parts support and service response in the commercial proposal. Tennant robotics technology overview.
Pilot acceptance measures
Measure completed clean area, cleaning quality, water recovery, repeat visits and operator intervention over several representative shifts. Record battery and tank service interruptions separately. Compare the total staff time needed to prepare, supervise and maintain the system with the existing cleaning process. Agree a response plan for a blocked aisle or unavailable charger before expanding beyond the trial area.
Sources and enquiry preparation
Primary sources were reviewed on 11 September 2026. Linked product information and the customer case are manufacturer statements with model and date boundaries. Supply a floor plan, cleaning-window requirement, peak pedestrian periods, utility locations and reporting needs when requesting a proposal. Ask the supplier to identify the exact machine generation, options and software entitlement, and to demonstrate acceptance criteria on the intended floors.
