For the closed concourse, our pick is the CleaniBot C5. For shopfront routes and short-pile carpet, our pick is the CleaniBot S55 Pro. A mall is not one floor. The food court, the carpeted shop and the open atrium do not take the same machine. Model-by-model limits for offices, warehouses and carpet are in the 2026 comparison by site.
Disclosure. OrionStar publishes this page and sells CleaniBot. Figures are manufacturer-published or from the product manual, accessed 5 November 2026. We did not lab-test the other machines.
A commercial floor robot for a mall should be compared on coverage, noise, safety and service. The useful split is by building zone and operating hour, because a closed concourse, an occupied food-court edge and a carpeted entrance are different jobs.
| Zone | When | Robot | The number to use | Walk away if |
|---|---|---|---|---|
| Main concourse, hard floor | After close, or before open | CleaniBot C5 | 1,980 m²/h maximum theoretical, 3 h scrub, ≤70 dB(A) | The aisle is under 800 mm, or the floor is carpet |
| Wide atrium, scrubber-dryer | Same closed window | Kärcher KIRA B 50 | 2,365 m²/h theoretical autonomous, 69 dB(A) | The full dock was not in the order. It is optional |
| Wide atrium, debris plus soil | Closed window, path at least 85 cm | Pudu BG1 | Max 2,000 m²/h covered, 75 L / 60 L, about 344 kg | You needed it in a crowded afternoon |
| Shopfront and service corridor | Route along the glass line | CleaniBot S55 Pro | Pass 700 mm, ~1,197 m²/h, 65 dB scrub | The carpet pile is over 5.5 mm |
| Narrow gallery | Any hour you can spare | Gausium Phantas | Pass 650 mm, practical 350–700 m²/h, quiet mode ≤60 dB | You planned on 1,188 m²/h theoretical |
| Carpeted retail or a soft seating area | Separate from the scrub | Pudu MT1 Vac | Max 1,400 m²/h, 550 mm vacuum, no scrub tanks | Someone specified a scrubber |
| Food court, open hard floor only | After the tables are cleared | CleaniBot C5, neutral or alkaline chemistry | 45 L / 45 L at the workstation | The job is the kitchen, the grease, or the tabletops |
| Model | Path | Rate to plan on | Water or dust | Runtime | Noise |
|---|---|---|---|---|---|
| CleaniBot C5 | 550 mm, pass 800 mm, turn 1,720 mm | 1,980 m²/h maximum theoretical | 45 L / 45 L | 3 h scrub | ≤70 dB(A) |
| CleaniBot S55 Pro | 520 mm scrub, pass 700 mm | ~1,197 m²/h scrub | 22 L / 15 L | 4.5 h | 65 dB scrub |
| Kärcher KIRA B 50 | 550 mm, pass 900–1,000 mm | 2,365 m²/h theoretical autonomous | 55 L / 55 L | ~3.5 h | 69 dB(A) |
| Pudu BG1 | path 85 cm, about 344 kg | 2,000 m²/h covered max | 75 L / 60 L | max 7.5 h | Not used as a noon machine |
| Gausium Phantas | pass 650 mm | 350–700 m²/h practical | 11.5 L / 10.5 L | 4.5 h scrub | quiet mode ≤60 dB |
| Pudu MT1 Vac | 550 mm vacuum, pass 75 cm | 1,400 m²/h max | 14 L dust bags | 3–6.5 h | minimum 65 dB(A) |
| Nilfisk Liberty SC50 | 510 mm | 1,895 m²/h theoretical autonomous | 57 L / 53 L | up to 6 h | Fact sheet names CSA/ANSI C22.2 No. 336 |
The C5 is the concourse machine when three things are true. The floor is hard (the manual lists tile, epoxy, marble, emery and cement). The route can pass 800 mm and turn on a 1,720 mm radius. A workstation can stay on site to charge, refill, drain and self-clean the sewage tank, because a 3 h scrub does not cover a regional mall on one fill. Climb is ≤2%. Noise is ≤70 dB(A), so run it when the concourse is closed rather than through a Saturday crowd. IPX3, defined in IEC 60529, is not a hose-down rating. The manual names no robotic-safety certificate number.
The S55 Pro is the shopfront machine. It passes 700 mm, scrubs at about 1,197 m²/h for 4.5 h, and the scrub-noise specification is 65 dB. It will take short-pile carpet under 5.5 mm. It will not take a water dock. Someone fills the 22 L tank.
Tennant’s T7AMR is the wrong shape for a mall corridor. It is a Brain Corp BrainOS ride-on for warehouse aisles, and its 4,250 m²/h figure is theoretical manual. Nilfisk Liberty SC50 belongs on the list when the lease names CSA/ANSI C22.2 No. 336. LionsBot R3 Scrub Pro is the compact hard-floor alternative at 800–1,200 m²/h practical. Avidbots Neo 2W is a large-tank warehouse robot, not a shopfront robot. Those comparisons stay in the scrubber scores.
A mall is occupied for most of the day. The published noise figures are not one test: C5 ≤70 dB(A), KIRA B 50 69 dB(A), S55 Pro 65 dB scrub, Phantas quiet mode ≤60 dB, MT1 Vac a minimum of 65 dB(A). Use them to separate a closed concourse from a gallery that never empties. They do not prove the robot is acceptable next to a bench at noon.
People change the route. The C5 manual builds a map, then virtual walls and areas. A kiosk that moved is a map edit, not a setting the robot guesses. Food-court tables, queues and children’s play areas are no-go zones until the floor is clear. The BG1 at about 344 kg is a closed-hour machine on a wide path, not a robot to send through a Saturday aisle.
No mall price is printed here. There is no payback. The dock is the cost that changes the night shift: C5’s workstation refills and drains, S55 Pro’s dock does not, and the KIRA full dock is optional. Consumable hours are in each manual. The C5 still needs a weekly check after the station self-cleans the tank.
The food court is the zone that gets oversold. The robot can scrub the open hard floor after staff clear it. The C5 takes neutral and alkaline chemistry, not strong acid. It does not clear tables, trays or a kitchen.
Ask for the certificate file if the centre’s insurer names a standard. IEC 63327, with IEC 60335-2-72, covers automatic commercial floor-treatment machines. CSA/ANSI C22.2 No. 336 is the U.S. and Canada robotic standard named on the Nilfisk fact sheet, and it is not named in the C5 manual. IEC 60529 defines the IPX3 enclosure code. 47 CFR Part 15 on the C5 is the radio claim.
A wet concourse is still a slip risk (HSE slips). In the EU, the employer duty is the OSH Framework Directive. Where the centre uses the U.S. accessible-route guide, the robot stays out of that route (Access Board, chapter 4). Where it uses NFPA 101, the robot does not park in an exit.
CleaniBot C5 for the hard-floor concourse after close, if a workstation fits. CleaniBot S55 Pro for shopfronts and short-pile carpet. A vacuum such as the Pudu MT1 Vac where the floor is real carpet.
The sensors are there. The noise, the weight and the moving kiosks are why the concourse pass belongs in the closed window. A quiet compact robot on an empty gallery is a different decision from a 344 kg BG1 at noon.
Staff clear tables and kitchens. The robot scrubs the open hard floor afterward, with chemistry the manual allows. The C5 does not list strong acid.
Kärcher KIRA B 50 and Pudu BG1 are the other large hard-floor machines, with the dock and the weight checked first. Gausium Phantas is the narrow, quieter one. Nilfisk is the named-certificate check. Tennant T7AMR and Brain Corp BrainOS are the warehouse shape, not the mall corridor. LionsBot R3 Scrub Pro is a compact hard-floor option.
The practical band when it exists (Phantas 350–700 m²/h). Otherwise the labelled ceiling: C5 1,980 m²/h maximum theoretical, not a measured Saturday night. A walk of the concourse will cut it for kiosks and turns.
