Tennant T7AMR vs Avidbots Neo: Floor Scrubber

The commercial floor-care equipment market split in two around 2019: traditional walk-behind and ride-on scrubbers on one side, and fully autonomous/semi-autonomous robotic scrubbers on the other. Both categories are now mature enough that procurement decisions require more than a spec sheet comparison — they require a full lifecycle cost model, facility suitability assessment, and realistic labor-offset calculation. This comparison covers the three machines that appear most frequently in commercial cleaning bids and facility management RFPs as of 2025–2026.

The Three Machines

Tennant T7AMR (Autonomous Mobile Robot)

Tennant's T7AMR is a retrofit of the well-established T7 platform, adding the Brain Corp OSARO navigation system. It is the dominant autonomous scrubber in US commercial deployments because most building service contractors already own T7s and the AMR upgrade path is lower-friction than purchasing a net-new robot platform. Tennant Company reported $1.17B in net revenues for FY2024, with autonomous products representing the fastest-growing segment. (Tennant FY2024 10-K)

Key specs (T7AMR):

• Cleaning path width: 28 inches (disk) or 20 inches (cylindrical)
• Tank capacity: 23-gallon solution / 23-gallon recovery
• Productivity (manual mode): 32,000 sq ft/hr theoretical; 15,000–22,000 sq ft/hr realistic with obstacles
• Productivity (autonomous mode): 12,000–18,000 sq ft/hr depending on environment complexity
• Battery: 3-AGM or Li-ion option; 3–4 hours runtime (Li-ion)
• Navigation: Brain Corp BrainOS — LiDAR + camera; map creation takes 1–2 hours per zone
• Connectivity: 4G/LTE + WiFi; remote monitoring via Tennant IRIS portal
• Price range (2025): $35,000–$52,000 (varies by scrub head, battery, and connectivity package)

Avidbots Neo

The Neo is a purpose-built autonomous scrubber from Avidbots, a Waterloo, Ontario-based company. Unlike Tennant's retrofit approach, the Neo was designed from the ground up as a robot, resulting in a lower center of gravity, better obstacle avoidance, and a smoother cleaning path in complex retail environments. Avidbots has deployments at major US grocery chains, airports, and big-box retail.

Key specs (Neo 2):

• Cleaning path width: 22 inches
• Tank capacity: 20-gallon solution / 20-gallon recovery
• Productivity (autonomous): 10,000–16,000 sq ft/hr typical
• Battery: Li-ion; 4.5-hour runtime
• Navigation: 3D cameras + ultrasonic sensors + IMU; no LiDAR — Avidbots claims this reduces maintenance cost vs LiDAR systems
• Connectivity: WiFi + 4G; Avidbots Portal dashboard; integration with Microsoft Azure for enterprise customers
• Price range (2025): $40,000–$58,000 (direct) or $1,500–$2,200/month (Robot-as-a-Service subscription)

ICE Cobotics Cobi 18

The Cobi 18 is the entry-level autonomous scrubber for mid-market commercial cleaners. ICE Cobotics (formerly Intelligent Cleaning Equipment) was acquired by ICE Robotics/ACCO Brands and targets building service contractors running 50K–300K sq ft facilities. It is a smaller machine — 18-inch cleaning path — with a correspondingly lower price point.

Key specs (Cobi 18):

• Cleaning path width: 18 inches
• Tank capacity: 12-gallon solution / 12-gallon recovery
• Productivity (autonomous): 8,000–12,000 sq ft/hr
• Battery: Li-ion; 3-hour runtime
• Navigation: camera-based; map setup ~45 minutes per zone
• Price range (2025): $18,000–$26,000 (direct) or available via Compass Group distribution channels

Side-by-Side Specification Matrix

Spec	Tennant T7AMR	Avidbots Neo 2	ICE Cobi 18
Cleaning width	28" disk / 20" cyl	22"	18"
Solution tank	23 gal	20 gal	12 gal
Recovery tank	23 gal	20 gal	12 gal

Total Cost of Ownership: 5-Year Model

The purchase price comparison above understates the true cost differential. Key variable costs:

5-Year Total Cost of Ownership — 1 Unit Per Machine (50,000 sq ft facility, 5 nights/week)

Category	Value
Purchase	$44K
Maintenance	$18K
Consumables	$12K
Training/integration	$5K

Labor offset calculation: At a 28% labor-hour reduction on a 50,000 sq ft facility requiring 2 cleaning staff at $20/hr, 260 nights/year × 3.5 hours/night each:

• Total labor hours/year (baseline): 1,820 hr
• Hours saved (28%): ~510 hr/year
• Labor cost saved/year: 510 × $20 = $10,200/year
• T7AMR payback on labor offset alone: ~4.3 years

The math improves significantly at facilities requiring more coverage or with higher wage rates (union markets, California, NYC).

Facility Suitability Decision Tree

RFP and Facility Manager Perspective

Large property managers (CBRE, JLL, Cushman & Wakefield) increasingly specify autonomous scrubber deployment in service contracts for Class A retail and airport concession cleaning. When a facility manager's RFP asks for "autonomous cleaning technology" or "cleaning robotics capability," here is what they typically mean and how to respond:

• Proof of prior deployment: Case study or reference facility where robots were deployed, with documented coverage metrics and quality-score outcomes.
• Integration with BMS: Can the robot's cleaning logs be exported to the building management system? Avidbots and Tennant both offer API integrations.
• Contingency plan: What happens when the robot is out of service? Manual staffing plan required.
• Insurance coverage: Some facility managers require the cleaning contractor to carry an endorsement for autonomous robot liability. Verify with your broker.
