Robotic Floor Scrubber Comparison

Two companies dominate the autonomous ride-on scrubber conversation for BSCs with 100,000+ sq ft facilities: Tennant, which retrofitted its existing ride-on scrubber line with BrainOS autonomy, and Avidbots, a Canadian robotics company that builds its Neo line as autonomous from the ground up. A third tier, smaller autonomous walk-behind units like ICE Cobotics' Cobi line, targets facilities that cannot justify a six-figure ride-on but still want unattended scrubbing on smaller footprints. None of these machines are interchangeable with a standard walk-behind auto-scrubber purchase decision; the economics only work past a certain square footage threshold, and that threshold differs by machine.

Tennant T7AMR: retrofit autonomy on a proven platform

The Tennant T7AMR is built on Tennant's existing T7 ride-on scrubber chassis with BrainOS autonomy (developed with Brain Corporation) layered on top. Specs: 26-inch cleaning path, 29-gallon solution and recovery tanks, up to 45,760 sq ft/hour theoretical coverage, 190 lb of brush down-pressure, and a sound level as low as 70 dBA. Battery run time depends on chemistry: 4 hours on flooded lead-acid, up to 6.5 hours on the lithium-ion option. Distributor pricing varies widely: San-A-Care and SweepScrub list the T7AMR-650-D configuration at $77,933–$94,129, while Swish's Canadian list price runs to $126,774. A smaller sibling, the T380AMR, uses a 20-inch path and 20-gallon tanks for tighter aisles at a lower price point, covering up to 33,440 sq ft/hour. Tennant backs the T7AMR with a stated 3-year machine warranty and 5-year software/subscription term on the units sold through Cleaner Floors and comparable dealers, though buyers should confirm exact terms since Tennant's warranty language differs by dealer bundle.

Avidbots Neo 2: autonomous-first, higher productivity per hour

Avidbots built the Neo 2 as a walk-behind-sized autonomous unit rather than a ride-on, which changes the economics and the use case. The 26-inch disc configuration covers a maximum theoretical 33,583 sq ft/hour (3,120 m²/hr); the 32-inch disc configuration reaches 41,432 sq ft/hour (3,850 m²/hr). Avidbots publishes both as calculated maximum theoretical values, not guaranteed field rates. Tank capacity runs 28.8 gallons solution / 35.7 gallons recovery on both widths, and battery run time is rated 4-6 hours on six 6V AGM batteries (36V, 250 Ah system). Avidbots' own team has quoted Neo 2 pricing in the "low $50,000s" range not including batteries, though third-party listings and resale platforms show new-unit pricing spanning roughly $54,000-$120,000 depending on configuration, region, and whether the deal is a direct purchase or includes Avidbots' fleet-management software subscription. A lighter-duty sibling, the Kas model, targets smaller and narrower spaces with a 22-inch disc head, a 2.5 mph top speed, and roughly 500-1,000 m²/hr practical productivity, aimed at retail aisles rather than warehouse floors.

ICE Cobotics and the sub-$10K autonomous tier

Below the six-figure ride-on category, smaller autonomous or semi-autonomous walk-behind scrubbers like ICE Cobotics' i15b-class units serve facilities that need unattended scrubbing on a much smaller footprint: locker rooms, small retail floors, school corridors. The i15b carries a 15-inch cleaning path, a 4-gallon fresh/5-gallon recovery tank split, a 0.1344 GPM flow rate, 140 RPM brush speed, and an advertised 13,500 sq ft/hour cleaning rate, though independent operator testing puts actual run time closer to 45 minutes against an advertised 1.2 hours — a real-world gap worth planning around. MSRP sits around $5,146 with street pricing closer to $3,400; individual parts run modestly: a squeegee blade set around $83.50, brush replacement around $220, and a replacement battery near $200. This tier is not autonomous in the SLAM-navigation sense that Tennant and Avidbots units are; it is better understood as a compact powered scrubber with reduced labor requirements, not a full robotic fleet asset.

Where the ROI threshold actually sits

A Tennant T7AMR or Avidbots Neo 2 purchase in the $55,000-$125,000 range only pencils out against displaced labor hours, not against a single account. At a loaded labor rate of roughly $18-$24/hour for a night-shift scrubber operator (varying heavily by BLS OEWS regional wage data and state minimum-wage floors), a machine running 20-30 scrubbing hours per week displaces one part-time or a chunk of one full-time position. On a single 150,000-200,000 sq ft distribution center or big-box floor, that math clears the equipment cost inside 24-40 months at typical utilization. Below roughly 80,000-100,000 sq ft of continuously scrubbable hard floor, a walk-behind or ride-on manual scrubber stays cheaper on a total-cost basis for at least the first equipment life cycle. Robot-as-a-Service (RaaS) lease structures, which several vendors offer in the $2,000-$5,000/month range including software and support, shift this math by removing the capital outlay but add a recurring cost that needs to be underwritten against a specific contract's term length.

Fleet management software and what it actually costs to run

• Tennant BrainOS: subscription-based software layer bundled into the T7AMR's stated 5-year software term on most dealer packages; ongoing subscription cost after that term varies by dealer
• Avidbots Command Center: cloud fleet dashboard reported by third-party integrators at roughly $500/month per unit in addition to the machine purchase or lease
• ICE Cobotics-tier units: no fleet software layer at this price point. These are standalone powered machines, not networked robotic assets
• Common overlooked cost: facility mapping and initial route-teaching typically requires 1-3 site visits from a vendor technician before autonomous mode is reliable, adding setup time that some proposals do not itemize separately

Frequently asked questions

Q: What size facility justifies a Tennant T7AMR or Avidbots Neo 2 over a manual ride-on scrubber? A: Most vendors and BSC operators put the practical floor at 100,000-150,000 sq ft of continuously scrubbable hard floor run on a repeatable nightly or multi-night schedule; below that, labor displacement rarely offsets the six-figure purchase or lease cost inside a reasonable payback window.

Q: Can these machines run fully unattended overnight with no staff on-site? A: Most facilities still schedule a technician or security presence during initial autonomous runs and for battery charging cycles; full lights-out unattended operation is technically possible on some deployments but is uncommon due to insurance and liability considerations tied to unsupervised heavy equipment.

Q: Do robotic scrubbers replace edge and detail cleaning entirely? A: No. All three machine classes covered here leave edges, corners, and obstructed areas that require manual follow-up with a walk-behind unit or mop — plan staffing around a hybrid model, not full displacement.
