T7AMR

Overview

The Tennant T7AMR is an autonomous floor scrubber built on Brain Corp's BrainOS autonomy platform, combining Tennant's established commercial scrubber-dryer hardware with market-leading autonomous navigation software. With a 3.5-hour runtime and a price of approximately $35,000, the T7AMR is positioned as a mid-tier autonomous cleaning solution suited to retail, logistics, and light industrial environments. BrainOS provides a fleet management portal that integrates with facilities management workflows, enabling scheduling, monitoring, and performance reporting.

Key Specifications

• Runtime: 3.5 hours per charge
• Autonomy platform: Brain Corp BrainOS
• Cleaning width: 71 cm (T7 platform)
• Price: Approximately $35,000
• Navigation: LiDAR and camera-based SLAM

BrainOS is notable for its machine learning-based navigation that improves over time as the robot builds familiarity with its environment. Initial route training is performed by a human operator driving the robot through the desired cleaning path, after which it operates autonomously.

Use Cases

UK deployments of the T7AMR are most common in large retail stores, distribution centres, light manufacturing facilities, and NHS trust buildings where consistent floor hygiene standards are required across large areas. The intuitive route-training process means cleaning staff can set up new routes without specialist robotics knowledge, which reduces dependency on external technical support.

Integration with Brain Corp's BrainOS cloud allows facilities managers to track utilisation, distance cleaned, and water usage across multiple units and sites from a single dashboard. This is particularly valuable for multi-site contract cleaning companies seeking to standardise performance metrics.

Buying Used

Used T7AMR units are reasonably available through commercial equipment dealers, as the Tennant T7 platform has been in production for several years and early fleet deployments are now coming up for replacement. BrainOS software is subscription-based, so confirm that the subscription can be transferred to the new owner and that the unit is running a supported firmware version. Tennant has a UK distributor network for ongoing service.

Alternatives to Consider

• Kärcher KIRA B 50 for a competing autonomous scrubber with strong UK service support
• Nilfisk Liberty SC50 at a slightly lower price point with a collaborative cleaning model
• Karcher KM 85/50 R Bp for a conventional ride-on scrubber if autonomy is not required
