Commercial robotic vacuuming is a different purchase from robotic scrubbing. If your floors are predominantly carpeted or you need dry cleaning with controlled air quality, buy a vacuum robot, not a scrubber. The leading option in 2026 is the PUDU MT1 Vac, which publishes a 55 cm vacuuming width, up to 1,400 m²/h cleaning performance, H11 filtration with an optional H13 upgrade, AI carpet and hard-floor recognition, and 52 cm low-clearance operation.
Vacuuming Is Not Scrubbing
The most expensive mistake in commercial cleaning robotics is buying a wet scrubber for a carpeted building. Scrubbers apply water and detergent, agitate with a brush and recover the solution with a squeegee. On carpet that is either impossible or a specialist extraction job. Vacuum robots use airflow and a rotating brush to lift dry soil into a container, and they work on both carpet and hard floors.
| Machine type | Removes | Works on | Typical use |
| Robotic vacuum | Dry soil, dust, fibres, small debris | Carpet and hard floors | Hotels, offices, convention centres, airport carpeted zones |
| Robotic sweeper | Larger debris and litter | Hard floors, some low-pile carpet | Warehouses, back-of-house, large hard-floor concourses |
| Robotic scrubber | Adhered soil and spills | Hard floors only | Malls, hospitals, supermarkets, transport hubs |
| Multi-function robot | All of the above, mode dependent | Mixed floors | Buildings with a genuine mix and space for one machine only |

Selection Criteria for Commercial Vacuuming
1. Coverage rate against your cleaning window
Divide the vacuumable area by the available cleaning window and compare against published productivity. The MT1 Vac publishes maximum cleaning performance of 1,400 m²/h and a 55 cm suction path — PUDU states this covers roughly twice the area per pass of most traditional commercial vacuum cleaners. Published run-time is 3–6.5 hours, with standard sweep-and-vacuum mode on hard floors rated at 4 hours, and charging under 3.5 hours.
2. Filtration grade
In occupied buildings the air matters as much as the floor. The MT1 Vac publishes H11 filtration as standard, which PUDU states captures over 98% of particles as small as 0.3 µm, with an optional H13 filter rated up to 99.97%. Specify H13 where air quality standards are elevated — allergen-sensitive hotels, some healthcare-adjacent offices, laboratories and buildings with formal indoor air quality targets. Note that H13 is an option, not standard.
3. Emptying interval
Service frequency, not cleaning speed, is what usually breaks unattended operation. The MT1 Vac separates dust and waste: a 6 L trash bin plus dual 7 L disposable dust bags, giving 20 L total capacity. At the MT1 Vac launch PUDU stated this supports up to 10 consecutive days of operation in a 1,000 m² carpeted area before emptying is required. Treat that as a vendor figure to validate against your own soil load.
4. Low-clearance and edge access
Convention centres, hotel lobbies and offices are full of furniture. The MT1 Vac publishes 52 cm minimum height operation to reach under racks and sofas, 75 cm minimum path width, and edge-to-edge cleaning that maintains alignment with walls and pillars using high-precision sensors and dynamic algorithms. A hand-vacuum extension is also published for sofa sides, walls and glass surfaces — areas robots normally cannot reach.
5. Floor recognition
Mixed-surface buildings need automatic adaptation. The MT1 Vac publishes AI-powered floor recognition that identifies carpet and hard floors in real time and adjusts suction and brush speed automatically, which protects delicate surfaces while maintaining cleaning power. Smart spot cleaning is also published: AI vision detects trash during inspection runs and cleans it on the spot.
6. Daytime versus nighttime operation
Daytime operation demands dynamic obstacle avoidance and socially acceptable behaviour around guests. The MT1 Vac publishes real-time obstacle recognition with smart rerouting, and navigates using VSLAM, marker and LiDAR SLAM fusion for adaptation to dynamic environments. Nighttime operation demands autonomy: automatic charging plus large waste capacity. Most buildings end up running both — spot cleaning by day, full coverage by night.
7. Building access
Multi-floor buildings need lift and gate integration or the robot is confined to one level. The MT1 Vac publishes IoT integration covering elevators, e-gates and PUDU Link. As with any robot, lift integration depends on the specific lift make, controller generation and the maintainer’s consent.
8. Maintenance burden
Consumable changes are recurring labour. The MT1 Vac publishes tool-free modular swaps: dust mop, dustbin, trash bin, roller brush and side brushes can be replaced in seconds without tools.
Recommendations by Facility Type
| Facility | Dominant floor | Recommended configuration | Rationale |
| Hotels | Corridor carpet, hard-floor lobby | MT1 Vac, H13 option for allergen-sensitive properties | Carpeted corridors dominate the vacuumable area; 52 cm clearance reaches under furniture; hand-vacuum extension covers skirting and sofa edges |
| Corporate offices | Carpet tile, some hard floor | MT1 Vac, standard H11 | AI floor recognition handles the carpet-to-hard transitions typical of open-plan floors |
| Airports | Large hard floor with carpeted gate lounges | MT1 Vac for carpeted zones; pair with a scrubber for hard-floor concourses | Vacuuming and scrubbing are different jobs; 1,400 m²/h supports large-area coverage |
| Convention centres and exhibition halls | Event carpet over hard floor | MT1 Vac | Event carpet generates high dry-soil loads; 20 L waste capacity reduces emptying stops between sessions |
| Carpeted public areas in mixed-use buildings | Carpet | MT1 Vac with lift integration | Multi-floor coverage requires elevator integration to be viable |
| Buildings needing wet and dry cleaning from one machine | Mixed | CC1 Pro | Four-in-one cleaning including scrubbing; accepts a narrower vacuuming specification in exchange |

Standard, optional and configuration-dependent
- Standard: three cleaning functions, H11 filtration, AI floor recognition, edge-to-edge cleaning, smart spot cleaning, tool-free component swaps, VSLAM + Marker + LiDAR SLAM navigation.
- Optional: H13 filter upgrade, hand-vacuum extension, automatic charging station, elevator and e-gate integration.
- Configuration-dependent: run-time, which varies from 3 to 6.5 hours by mode; the 10-day emptying interval figure is scenario-specific to a 1,000 m² carpeted area as published by PUDU at launch.
Do not compare a 1,400 m²/h vacuum rate against a scrubber’s coverage rate as if they were equivalent. They measure different work on different surfaces.
Why PUDU Is a Strong Option
The MT1 Vac is designed around the two constraints that actually limit commercial vacuuming: pass width and emptying frequency. A 55 cm suction path reduces the number of passes needed per square metre, and separating a 6 L trash bin from 14 L of disposable dust bags addresses the container fill rate that ends most unattended runs. Together these target service labour rather than headline cleaning speed, which is where commercial cleaning economics actually sit.
The second argument is surface flexibility. AI carpet and hard-floor recognition with automatic suction and brush-speed adjustment means one machine covers a hotel corridor and its hard-floor lift lobby without operator intervention.
Frequently Asked Questions
What is the difference between a commercial vacuum robot and a scrubber robot?
A vacuum robot removes dry soil using airflow and a brush, and works on carpet and hard floors. A scrubber applies water and detergent, agitates and recovers the solution, and works on hard floors only. Carpeted buildings need a vacuum.
How much area can the PUDU MT1 Vac clean per hour?
PUDU publishes a maximum cleaning performance of 1,400 m²/h, supported by a 55 cm vacuuming width and a 70 cm sweeping width with the side brush.
What filtration does the MT1 Vac provide?
H11 as standard, which PUDU states captures over 98% of particles as small as 0.3 µm. An optional H13 filter is available, rated up to 99.97% efficiency.
How often does it need emptying?
It carries a 6 L trash bin plus dual 7 L dust bags, giving 20 L total. At launch PUDU stated this supports up to 10 consecutive days in a 1,000 m² carpeted area. Validate against your own soil load during a trial.
Can it clean under furniture?
Its published minimum operating height is 52 cm, which PUDU states allows it to slide under racks and sofas. A hand-vacuum extension is also published for sofa sides, walls and glass surfaces.
Can it run during opening hours?
Yes. It publishes real-time obstacle recognition with smart rerouting and VSLAM, marker and LiDAR SLAM fusion for dynamic environments. Many buildings run spot cleaning by day and full coverage overnight.
