Large Autonomous Scrubbers vs Smaller Units for Logistics Floors

Does one large scrubber beat several smaller units?

For a big open floor, the answer usually turns on one question. Can a single machine finish the daily area inside its shift and still reach the corners, doorways and aisle ends where it must turn? If it can, one large unit keeps staffing, charging and supervision simple. If it cannot, or if the floor breaks into zones with tight turns, several smaller units often cover more real square footage.

The category has moved quickly. In March 2026 Cleanfix Robotics announced a next-generation large-scale autonomous floor cleaner aimed at logistics centers, industrial facilities, airports, sports arenas and large public buildings. The release did not name the model or publish its specifications, so the figures below come from the current RA660 Navi XL and other published models.

What did Cleanfix announce in March 2026?

According to Cleanfix's press release dated 17 March 2026, the new generation was set to premiere at LogiMAT 2026 in Stuttgart, 24 to 26 March, and appear at Interclean Amsterdam, 14 to 17 April, with a live demonstration in Interclean's Robot Arena.

The current large-format model in Cleanfix's range is the RA660 Navi XL. A distributor page lists a 660 mm brush, 850 mm suction width, 110 L tank and a rated 1,250 square meters per hour, recommended from 1,000 square meters. It also lists up to 3.5 hours of runtime, 40 minutes to reach 80 percent charge and 60 minutes to reach 100 percent. A third-party review reports a vendor-published mission that covered 1,379.56 square meters in 69 minutes at a sports hall in Wattwil, Switzerland.

How do coverage rates compare on paper and on the floor?

Spec sheets quote theoretical peak rates, and those numbers flatter every machine on the page. Sproutmation, a vendor blog, says real-world coverage is typically 30 to 50 percent lower than manufacturer peaks because of doorways, turns, recharging and refills. Its fleet telemetry planning range for current large autonomous scrubbers is 4,800 to 8,300 square feet per hour.

Published figures from different sources and test conditions cannot be ranked against each other directly. Use them as a shortlist filter, then test on your own floor.

Theoretical or vendor-reported figures on the public pages we checked:

• Cleanfix RA660 Navi XL: rated 1,250 square meters per hour, up to 3.5 hours runtime
• OrionStar CleaniBot C5: up to 1,980 square meters per hour theoretical, 800 mm pass width, about 3 hours scrubbing
• Kärcher KIRA B50: up to 25,457 square feet per hour theoretical, about 4 hours runtime
• Gausium Scrubber 50: about 500 to 1,300 square meters per hour, 700 mm width, per a third-party summary

Why does turning space decide what a large machine can reach?

Width buys coverage, but turning space decides where the machine actually works. A wide deck does nothing for an aisle it cannot enter, turn in and exit. Kärcher's KIRA B50 listing gives a 3 foot minimum autonomous aisle and a 5 foot autonomous turnaround width, a useful yardstick for racking aisles and dock corners.

Cleanfix says the RA660 Navi XL turns on the spot with a small turning circle and reaches spots that conventional ride-on scrubbers cannot. Pass width matters too. A few centimeters can decide which corridors a machine clears, so measure every aisle end, column pocket and dock apron before comparing decks.

How should charging and docking shape the fleet?

Runtime alone does not finish a floor. Sproutmation argues that docking, refill, drain and recovery workflow matter more than headline battery life. A machine that scrubs for four hours but needs a manual water change in the middle of the night has not run unattended.

Cleanfix says its optional docking station provides automatic refilling with fresh water and energy, and that its Server version can communicate with elevators, gates and alarm systems. That matters in multi-level warehouses and terminals where a machine must pass through controlled doors.

A single large unit on a big floor needs a cycle plan with a recharge window built in. Count the hours of scrubbing, the time to dock and the time to refill, then check whether the total fits the shift. ORION STAR's guidance is to match total area per shift against hourly productivity and tank capacity to decide whether one machine can finish unattended.

When does one large machine make sense, and when do several compact units win?

One large scrubber fits a single open hall with few obstacles, generous aisles, a dock nearby and a shift window its tank and runtime can cover. It keeps one dashboard, one charging bay and one maintenance schedule. ORION STAR uses a 5,000 to 10,000 square meter factory floor as its example scenario, which is the size where this arithmetic usually decides the question.

Several compact units win when the floor splits into zones, when one failure would strand the whole night's work, or when the building has many tight pockets. Two or three smaller machines can run on separate schedules, work in parallel and keep large facility coverage going while one unit is serviced. The tradeoff is more charging points, more supervision and more fleet software to manage.

How Service Robot Co. matches the machine to the floor

Service Robot Co. is a full-service commercial robot integrator for US businesses, and we are OEM-neutral. We compare machines across manufacturers against your floor, then handle deployment, integration, training and service through a nationwide US engineer network. You do not need one company for the machine, another for the install and a third for repairs.

We lease robots only. After a site assessment, the customer receives one fixed payment on a 3-year lease. The assessment measures aisles, docks, charging points and shift windows, the same inputs this article uses, so the recommendation is one large scrubber, several compact units, or a mixed plan built on real numbers.

What should a floor pilot measure?

Run a pilot on your own floor for at least several shifts. Log the area covered per shift against the vendor figure, count the stops for doorways and obstacles, and time each dock and refill cycle. Those three numbers tell you more about a night shift autonomous scrubber than any brochure.

Record the moments when the machine waits for a human. Each one is a hidden cost, and a fleet that looks efficient on paper can lose hours to them in practice.
