Tennant T7AMR · specifications, operator review and alternatives (2026)

The Tennant T7AMR is a ride-on autonomous floor scrubber launched in 2019, one of the first of the AMR wave, aimed at retail, supermarkets and logistics. It scrubs a 660 mm path, carries 110 L of water and runs continuously thanks to opportunity charging (up to 13 h in 24). It can also be driven manually. One point to watch: in robot mode it takes no gradient at all, so a level floor is mandatory. Price and availability on request.

Reading by environment

Floor area band110 L of water and opportunity charging (up to 13 h in 24): built to sustain long shifts in retail and logistics. Sits between the T380AMR (75 L) and the T16AMR (190 L) in capacity.
Footprint / aisles660 mm ride-on base: clear aisles are needed, but it is less bulky than the T16.
Floor / topographyMajor limit: 0% gradient in robot mode. The slightest ramp rules out autonomous use; a strictly level floor is mandatory. Check this first on site. No carpet.
Occupancy / hours70 dBA, the highest in the range: better suited to hours without a dense public.
PlumbingNo docking station: manual fill and drain, offset by its endurance under opportunity charging.
Operating profileManual ride-on driving available as a fallback, established Tennant after-sales service. Proven but ageing platform (2019).

Floors and soiling

Disc scrubber-dryer for hard floors: stuck-on and wet soiling, no carpet. Large debris must be pre-swept. The structural issue is topography: robot mode accepts no gradient at all, which makes it a machine for level floors only.

What the manufacturer does not say

Zero gradient in autonomous mode. This is the most important eligibility criterion, and it is not given prominence: a site with the slightest ramp cannot run it as a robot.

Productivity figures not to be confused. Tennant publishes an area per charge (m² per charge), not an observed m²/h: the two are not comparable.

No published client reference for this model (mentions of the global BrainOS fleet are not clients). A 2019 platform, to be weighed against the more recent ROVR models. Cost structure: machine plus consumables plus manual water handling.

Purchase or outsourced service

On a purchase (capex), the structural constraint is the zero gradient in robot mode: a site with the slightest ramp cannot run it autonomously, and water handling has to be managed in-house. Under an outsourced service (opex), the contractor confirms this level-floor eligibility and guarantees continuity. See the Pudu range and the on-site demonstration, or our robotic cleaning service.

Strengths and limits

Strengths

  • 110 L of water and opportunity charging: long operating shifts.
  • Manual driving as a fallback, established Tennant after-sales service.
  • Proven AMR platform.

Limits

  • 0% gradient in robot mode: level floor mandatory.
  • No docking station, 70 dBA (the noisiest in the range).
  • Ageing platform (2019) compared with the native ROVR models.

Alternatives

  • Within the Tennant range: the X6 ROVR (native AMR, 95 L, dock) as the recent successor; the T380AMR below it.
  • Against other autonomous floor scrubbers: the Kärcher KIRA B 50 and the Gausium Scrubber 50 Pro.
