Choosing a commercial floor-cleaning robot is not a "bigger is better" decision. The CLEINBOT line spans three very different machines — the M79, the C2 Pro, and the CC201 — each engineered for a distinct surface, layout, and workload. Buy the wrong one and you either overpay for capacity you will never use, or underbuy and leave your night shift struggling to keep up.
The three machines sit at opposite ends of the spec sheet. The CLEINBOT M79 is a 95 kg indoor scrubber doing 2,000 m²/h with a 720 mm cleaning deck. The CLEINBOT C2 Pro is a 42 kg compact unit doing 500–800 m²/h with a 440 mm deck, small enough for narrow corridors. The CLEINBOT CC201 is the outdoor outlier — a 310 kg, 3,000 m²/h sweeper with a 1,020 mm deck, GPS navigation, and IP67 water resistance.
This guide breaks down the exact differences, runs the coverage math for each, and gives a decision framework so you can match robot to surface area, floor type, and budget rather than guessing.
The Three Machines at a Glance
| Spec | CLEINBOT M79 | CLEINBOT C2 Pro | CLEINBOT CC201 |
|---|---|---|---|
| Best for | Indoor hard floors (lobby, warehouse, hospital) | Tight indoor spaces (corridors, retail aisles, offices) | Outdoor & rough surface (plaza, carpark, industrial park) |
| Cleaning deck | 720 mm | 440 mm | 1,020 mm (sweep) |
| Efficiency | 2,000 m²/h | 500–800 m²/h | 3,000 m²/h |
| Weight | 95 kg | 42 kg | 310 kg |
| Water capacity | 45 L clean / 40 L dirty | 10 L clean / 10 L dirty | 130 L auto-emptying dust bin |
| Navigation | LiDAR SLAM + RGB-D | LiDAR + RGB-D | GPS + LiDAR + IMU fusion |
| Battery / runtime | 48V 120Ah / 8 h | LiFePO4 25.6V 36Ah | 72V 150Ah / 10 h |
| Speed | 0.2–0.8 m/s | 0.1–0.8 m/s | 0.5–1.5 m/s |
| Slope | ≤5° | — | ≤8° |
| Weather rating | Indoor | Indoor | IP67, −10°C to 50°C |
Where the M79 and CC201 overlap is the largest source of mis-buying. A plaza or external walkway with rain, dust, and 8° ramps is the CC201's job — an indoor M79 parked outside is an expensive mistake. Conversely, putting a 310 kg outdoor sweeper inside a polished hospital lobby is overkill that the IP rating does not justify.
Coverage Math: Matching Robot to Floor Area
The single most useful question is simple: how fast do you need to cover, and in what window?
M79 (2,000 m²/h). A mid-size facility with 12,000 m² of hard floor gives you roughly 6 hours of runtime to complete a full pass. At 8 h of battery life that fits comfortably inside one overnight shift. For a 30,000 m² warehouse, plan for 15 hours — meaning two robots or a single unit with one intermediate charge, which is exactly where fleet stacking starts to make sense (service robot fleet management).
C2 Pro (500–800 m²/h). This is the access machine, not the volume machine. A 3,000 m² office with narrow corridors, glass partitions, and furniture gets a 4–6 hour pass — but the robot fits through an 800 mm doorway and turns inside a lift lobby, where a 720 mm unit cannot go. For compartmentalized layouts, the C2 Pro often finishes faster in practice than its m²/h suggests, because it does not get wedged.
CC201 (3,000 m²/h). A 20,000 m² outdoor plaza, car park, or industrial access road is ~7 hours of continuous sweeping. Its 130 L bin auto-empties into a dock, so it does not stop for emptying mid-run.
Decision threshold: as a rule of thumb, above roughly 15,000 m² of contiguous open hard floor, the M79 or CC201 (by surface type) wins on cost per square metre. Below that, or with dense obstacles, the C2 Pro's compactness beats raw rate. For the full economic picture including labour and maintenance, read our service robot ROI guide.
Matching to Floor Type
Surface is a second hard filter that many buyers skip.
- Polished stone, terrazzo, sealed concrete — M79. Its wet-scrub + mopping pass with adjustable water flow (0–300 mL/min) handles a glossy finish without streaking.
- Carpet overlay, rubber tile, tight vinyl — C2 Pro. The 10 L clean-water tank and lower scrub pressure suit lighter, more fragile coverings, and the unit is light enough not to mark soft flooring.
- Asphalt, block paving, gravel-edged kerbs, wet weather — CC201. The 1,020 mm sweep deck is designed for debris and dust pickup outdoors, with a 10 h battery and IP67 housing that tolerates rain and open-air duty.

If you only care about the cleaning mode itself rather than the robot, the commercial cleaning robot buyer's guide walks through scrubbing versus UV-C versus multi-mode.
Indoor vs Outdoor: Why M79 and CC201 Are Not Interchangeable
The most expensive single mistake in this product category is treating the indoor scrubber and the outdoor sweeper as one machine. The differences are structural, not cosmetic:
Navigation. The M79 runs LiDAR SLAM + RGB-D camera, which builds 2D maps of a defined indoor environment. The CC201 fuses GPS, LiDAR, and IMU — because outdoors there is no ceiling or wall to constrain LiDAR, and GPS provides absolute positioning across an open, shifting site.
Climbing. The M79 manages ≤5° of slope. The CC201 climbs ≤8° — the exact number you find on parking-garage ramps and plaza steps. A 6° ramp is a non-starter for the M79 and routine for the CC201.
Weather. IP67 means the CC201 shrugs off rain and operates from −10°C to 50°C. The M79 is a clean, climate-controlled indoor device. None of this is a quality defect — it is a design boundary you are buying around.
The C2 Pro Case: Compactness Saves the Day
The C2 Pro is easy to dismiss because its 500–800 m²/h number sits an order of magnitude below the M79. But in a dense, compartmentalized layout — an office floor, a retail backshop, a clinic — it is often the only CLEINBOT that physically fits. Its 440 mm deck and 42 kg weight let it pass through a standard 800 mm door and navigate a tight lift lobby without hand-walking.
Choosing between M79 and C2 Pro in a confined space comes down to real geometry, not spec sheets. Map your narrowest doorways and tightest turns first, then work backwards to the robot.
ROI: Payback by Robot
| Configuration | Robot | Annual labour savings | Robot + upkeep | Net annual | Payback |
|---|---|---|---|---|---|
| 12,000 m² indoor | 1× M79 | $112,000 | $26,000 | $86,000 | ~9 months |
| 4,000 m² office (confined) | 1× C2 Pro | $68,000 | $14,000 | $54,000 | ~7 months |
| 18,000 m² outdoor plaza | 1× CC201 | $126,000 | $31,000 | $95,000 | ~10 months |
| Mixed site (indoor + outdoor) | M79 + CC201 | $238,000 | $57,000 | $181,000 | ~11 months |
Assumptions: US labour at $22/hr fully loaded, 20 h/day utilisation, 5-year depreciation. Payback accelerates where labour is pricier (Western Europe, Gulf, Singapore). Budgeting for the deployment rather than the robot alone is the key — see our budget planning methodology and maintenance & TCO guide.
A Decision Framework in Three Checks
Check 1 — Surface. Indoors (polished/concrete) or outdoors (asphalt/plaza/rain)? Outdoors → CC201. Indoors → continue.
Check 2 — Access. Do your narrowest doorways and turns fit a 720 mm deck? Yes → M79. No → C2 Pro.
Check 3 — Volume. Is there enough contiguous area (roughly >15,000 m²) to justify the bigger machine? Yes → the largest that still passes Check 2. No → step down in deck size.
Run all three and the right CLEINBOT usually announces itself. When the site is large and mixed, the M79 and CC201 are complementary, not competing — and you should model them as a fleet (see the ROI table above).

The Takeaway
There is no "best CLEINBOT" — only the right one for a given floor, layout, and budget. Match the M79 to large indoor hard floors, the C2 Pro to tight compartmentalised interiors, and the CC201 to outdoor debris and weather. Use the coverage maths above to size it, the access checks to filter it, and the ROI table to justify the spend. Start with a cleaning robot pilot on your highest-volume surface, measure for 30 days, and expand on the data.
