What Is Cobotics? Collaborative Cleaning Robots Explained
Rod Michelini is the founder of OneUp Cleaning. We sell one cleaning cobot today, the ICE Cobi 18, so it's the example on this page, but everything here applies to any maker's robot.
Cobotics, short for collaborative robotics, means robots and people sharing one job instead of the robot replacing the person. In commercial cleaning, the cobot is usually an autonomous floor scrubber, some only 18 inches wide, that runs the repetitive open-floor passes while your staff set it up, empty it and handle edges, spills and restrooms.
If the definition is all you came for, you can stop here. If you have to make cobotics work in your building, with a robot and a crew acting as one team, the rest of this page is for you.
What does cobotics mean?
Cobotics is the branch of robotics that builds and runs robots meant to work with humans rather than walled off from them. The word comes from "cobot," a robot built for direct contact with the person using it.
The idea started in a lab, not your janitor's closet. In December 1996, the Chicago Tribune reported that Northwestern University engineers J. Edward Colgate and Michael Peshkin were developing a new concept in robotics, the "cobot", with a General Motors engineer as co-investigator.
Their patent, filed in 1997 and granted in 1999, describes direct physical interaction between a person and a general purpose manipulator.
Those first cobots were factory machines built with car assembly in mind. The word later spread to any robot designed to share your space, and the cleaning industry adopted cobotics as its name for human-robot collaboration on the floor. ICE even put it in its company name, and it defines a cobot as a collaborative robot designed to work alongside staff.
What is a cobot?
A cobot is a robot built to work in the same space as you, so it limits its speed, force or path whenever someone is close. You'll meet two very different kinds of cobots under that name.
In a factory, a cobot is usually a robot arm sharing a workbench with an assembler, and an international standard adds safety requirements for collaborative industrial robot operation. In your building, a cobot is a mobile machine that drives its own route across your floor, watching for feet, carts and shelving instead of a worker's hand. It's the same idea in a different machine, and as you'll see, it follows different rules.
Cobot vs robot: what's the difference?
A traditional robot keeps people out, while a cobot is designed to keep working with people around it. Most guides compare only the first two columns of this table, so here's the third one you'll actually deal with:
| Traditional industrial robot | Industrial cobot | Cleaning cobot | |
|---|---|---|---|
| Where it works | Inside a fence or cell | On a bench next to a worker | On an open floor with staff and the public |
| How it stays safe | Guards and interlocks stop it when someone enters | Built-in speed and force limits | Sensors that slow, stop or steer it around people and drops |
| Who works beside it | Nobody while it runs | One operator, hands on | Your crew, plus anyone walking by |
| Main safety standard | ISO 10218 | ISO 10218 with ISO/TS 15066 | IEC 63327, CSA/ANSI C22.2 No. 336 |
| Typical job | Welding, heavy handling | Assembly, machine tending | Scrubbing or vacuuming large floors |
| Example | A caged welding cell | A Universal Robots arm | An ICE Cobi 18 scrubber |
The standards row is where most of what you'll read online gets it wrong, so it gets its own section.
Which safety standards apply to cleaning cobots?
Not the two everyone quotes. Most articles about cobots point you to ISO 10218 and ISO/TS 15066, but both cover industrial robots. ISO states that ISO/TS 15066 does not apply to non-industrial robots, even though its safety principles can still be useful elsewhere.
The revised ISO 10218-1:2025, published in February 2025, also leaves out service robots working where the public can have access, which is exactly where your lobby scrubber works.
Two standards do cover the cobots you'd buy for cleaning:
- IEC 63327:2021 sets requirements for automatic floor treatment machines for commercial use, including robots working close to large groups of people in places like malls and schools.
- CSA/ANSI C22.2 No. 336-17, reaffirmed in 2022, covers battery-operated commercial robotic floor treatment machines in North America. Nilfisk's co-bot guide calls it the first safety standard for commercial robotic floorcare machines and lists what it checks: stopping distance, obstacle detection, drop detection, critical zones, parking brakes, maximum speed and a start-up warning sound.
When you compare cobots, ask which of those two safety standards the machine was tested to, and ask to see the paperwork. A listing still doesn't make every route safe, because, as the International Federation of Robotics puts it, a safe robot does not guarantee a safe collaborative application. Your routes, schedules and training still decide that.
Standards status checked in October 2026; IEC forecasts a second edition of 63327 for 2027. If you'd like a second pair of eyes, send the model you're considering through the contact page and we'll request the maker's conformity documents for you.
How does cobotics work in commercial cleaning?
The robot takes the repetitive open areas, and your people take everything that needs judgment. That split is the whole point of cobotics in cleaning.
Picture your school at 9 p.m. with one of three custodians out sick. Normally the main hallway gets a rushed mop or nothing at all, because restrooms and trash come first, and the complaints arrive before first period.
With a cobot running that hallway on its taught route, your two custodians spend those hours on restrooms, classrooms and the corners the robot can't reach, so by morning the building looks like all three showed up.
What the robot does
Cleaning cobots repeat a route someone taught them, scrubbing the same area the same way every run. When you or a customer get close, the machine slows, stops or turns away. One custodian walked his cart up to a store robot and watched it stop about a foot and a half away, turn off and come back later to clean where he'd stood, and four other operators and viewers describe the same behavior.
What your staff still do
This is the half of human-robot collaboration the brochures skip. Ten people who run or work beside these robots, across Reddit threads and YouTube comments, describe the same jobs for your crew:
- Teach and start routes. Someone drives each route first, then starts it on each section.
- Fill, empty and rescue it. One store commenter lists the routine: fill the water, empty the dirty tank, drive it to its route markers and rescue it when it asks for help.
- Sweep first, since many scrubber robots don't sweep.
- Do the edges. One custodian saw a store robot leave about half a foot unscrubbed along the walls, and one school district's staff still mop the hallway edges after each run.
- Handle spills, restrooms and anything unusual, because a machine sees an obstacle, not a broken jar.
ICE's own daily checklist for the Cobi 18 tells you to check that the recovery tank is empty and wipe off the cliff sensors, and it says the machine still needs a person to set it up and maintain it.
| Task | Robot | Your crew |
|---|---|---|
| Open-floor scrubbing on a set route | Yes | Starts it |
| Teaching new routes | No | Yes |
| Sweeping ahead of the robot | No | Yes |
| Corners, wall lines, under fixtures | No | Yes |
| Filling, emptying, rinsing tanks | Only with a docking station | Yes |
| Spills, restrooms, odd messes | No | Yes |
| Rescuing a stuck or stopped robot | No | Yes |
So "collaborative" describes your workflow more than the machine. That's how one maker can say its machine works without operator oversight while every operator still keeps a list of jobs around it.
Where do cleaning cobots work well, and where do they struggle?
They shine on large, open, uncluttered floors and struggle wherever things move. A veteran cleaning-industry consultant ranks airports and long hallways as ideal and detail work as weak, and nine operators in all describe the same pattern.
Furniture is where you'll usually hit trouble. One school had to stack hallway tables and chairs first because the machine's sensors missed spindly legs.
Your building's people are the other variable: operators report passers-by hitting the emergency stop, and one district's principals refused to let the robots run during the school day. Before you buy, check your building against the robotic floor scrubber requirements checklist.
Does a cobot replace a cleaner?
Usually not, and you shouldn't buy one expecting it to. One worker whose grocery store runs a robot says a person can still do far more than the machine, and another store worker says their crew was trained to run the robot and mop what it misses, with nobody let go.
So does anything change for the crew? Sometimes. On the first video, three store workers say cleaning positions were cut or moved to stocking, so a robot can change your crew's jobs even when it doesn't remove them.
If you're building the business case, the guide to robotic floor scrubber cost shows how to count the labor hours a robot really frees.
What does a cleaning cobot look like day to day?
On the ICE Cobi 18, currently $18,000 on our store, your routine looks like this. It scrubs an 18.8-inch path with a 2.6-gallon solution tank and a 2.9-gallon recovery tank, finds its way with lidar and cliff sensors, and stores up to 60 of your routes.
ICE's own customer video shows what changes for your staff. A convenience store that spent 3 to 4 hours mopping now runs the robot about 10 times a day while its cashiers stock shelves and put orders away. They still wash out the magnetic trays and check the brushes after every route, so your team mops less and spends more time on the work only a person can do.
Frequently asked questions
Is a cleaning robot really a cobot?
Yes, in the way you'll hear the cleaning industry use the word, though not in the strict industrial sense, because it doesn't work hand in hand with one operator. It earns the name by working alongside your people and leaving the judgment calls to them.
Are cleaning cobots safe around customers?
They're designed to be. A robot tested to CSA/ANSI C22.2 No. 336 is checked for obstacle detection, stopping distance and top speed, and IEC 63327 covers the same class of machine internationally.
You still decide where and when it runs, and busy daytime areas usually call for shorter routes.
How much does a cobot cost?
Industrial arm prices won't tell you much about cleaning robots. The Cobi 18 sells for $18,000 on our store, larger robots cost far more, and the robotic floor scrubber cost guide breaks down your payback.
What is an example of a cobot?
In a factory, a robot arm that helps a worker assemble parts. In your building, an autonomous scrubber like the Cobi 18 that covers open areas while your staff handle spills, corners and restrooms.
