PUDU BG1 AI-Native Large Scrubber-Dryer Robot

Push a rotating broom through a puddle and the puddle does not disappear. It becomes a long, dirty streak dragged across the aisle, and now there is more floor to fix than before. The PUDU BG1 AI-Native Large Scrubber-Dryer Robot is built to avoid exactly that mistake. When it detects a wet spill, it instantly retracts its sweeping modules so the liquid is not spread any further. That one behavior sums up the machine: a large autonomous scrubber-dryer that reads the floor ahead and changes how it works, instead of running the same routine over whatever happens to be in its path.

Robots USA sells the PUDU BG1 to facility managers, building service contractors and systems integrators, and supplies it directly to the commercial and industrial sites where it will run. Robots USA prepares each quotation around your floor plan and cleaning schedule, covers the robot together with its station and any optional equipment, arranges delivery, and supports the machine after it goes into service. You deal with one team from the first question to routine operation.

Background

PUDU ROBOTICS and the step into heavy floor care

PUDU ROBOTICS made its name with service robots that work in restaurants, hotels and other busy commercial interiors, where moving safely among people is an everyday requirement rather than a special case. The BG1 applies that background to a tougher job: large-area floor care, where a machine has to cover open space for long stretches, handle both dry debris and liquids, and share the floor with shoppers, travelers, staff and equipment. It sits at the large end of the PUDU cleaning range, above compact and mid-size scrubber-dryers aimed at smaller floors.

Fusion positioning and an AI-native approach

The BG1 locates itself through Lidar + 3D VSLAM Fusion Positioning. Lidar measures the geometry of the space around the robot, while visual SLAM builds a picture of the surroundings from camera data. Combining the two is a common way to keep positioning reliable in places where one method alone can struggle, such as long, repetitive corridors or open halls where furniture and people move constantly. The "AI-native" label describes a machine designed from the start to perceive and decide, and the wet-spill response is the clearest published example: the robot recognizes the condition and reconfigures itself without anyone stepping in.

Technical Specifications

How does the PUDU BG1 deal with spills and dry debris on the same floor?

Most large floors carry both kinds of dirt at once: grit, packaging scraps and dust in one zone, a spilled drink or tracked-in rainwater a few steps away. The BG1 sweeps and scrubs in a single pass, collecting loose debris into its 5L trashbin while it scrubs and recovers water. The problem with combining those jobs is the spill, where a sweeper does more harm than good. The BG1 answers that directly. When it detects a wet spill, it retracts the sweeping modules immediately, so the liquid is picked up by the scrubbing and recovery system instead of being thrown or smeared across the floor.

For chemistry, the BG1 carries dual agent tanks totaling approx. 7 L. Two separate tanks let a site keep different cleaning agents on board, which is useful where one area needs a degreaser and another a neutral cleaner. The 75 L clean water tank and 60 L waste water tank are sized for long passes across open space, and the published run-time of up to 7.5 h of sweeping and scrubbing lets the robot cover a full overnight shift on a single charge, depending on the floor and the settings.

Productivity depends on the mode. In Covered Cleaning Mode, which works systematically across a mapped area, the published maximum is 2000 m²/h. In Spot Cleaning Mode, aimed at targeted cleaning, the maximum rises to 6000m²/h. Cruise speed ranges from 0.2 to 1.0 m/s, so the robot can slow down in crowded zones and move faster across empty halls.

What does the all-in-one station change for day-to-day operation?

A large autonomous scrubber still needs servicing. Someone has to refill clean water, drain the dirty tank and recharge the battery, and on a manual machine that routine can take up a real share of a shift. The BG1's all-in-one station automates refilling, drainage and charging, so the robot can come back, service itself and head out again without a technician standing by.

Charging uses automatic voltage detection. On a high-voltage supply (AC≥180V), a full charge takes about 3 h; on a low-voltage supply (AC≤180V), about 4.5 h. That matters when you plan where the station goes and how missions are scheduled around charging windows. Fully unattended operation is supported but requires the optional workstation, and Robots USA confirms the station and workstation configuration for your site in the quotation.

Connectivity supports the same goal. The BG1 supports 4G, Wi-Fi and Bluetooth, and optional E-gate/Elevator communication lets the robot pass through access gates and ride elevators between floors where the building infrastructure allows it. For a multi-level site, that is the difference between a robot assigned to one floor and one that covers the building.

Who is the PUDU BG1 for?

The BG1 is built for operators of large, open indoor floors: airport terminals, shopping malls, exhibition halls, transit stations, warehouses and logistics centers, factories and large retail stores. It suits building service contractors who want to stretch a limited crew across more square meters, and facility managers who need consistent results on night shifts without adding staff. Integrators working on gated or multi-floor buildings will find the optional E-gate/Elevator communication worth discussing early.

Plan for the robot's footprint. The BG1 needs a minimum path clearance of 85 cm (33.5 in), so narrow back-of-house corridors and tightly packed aisles may be better served by a smaller machine. For tighter spaces, the PUDU ET1 AI-Native Compact Scrubber-Dryer Robot and the PUDU CC1 Pro Disc AI-Native Mid-Size Disc Scrubber-Dryer Robot are the natural comparisons. Buyers considering the higher trim should also look at the PUDU BG1 Pro AI-Native Large Scrubber-Dryer Robot. Robots USA can lay out the differences between the two versions in a side-by-side quotation. The full range is in our Cleaning Robots category.

What is the PUDU BG1 used for?

1. Airport concourses: scheduled sweeping and scrubbing of long, open walkways, with spill response when liquids hit the floor.
2. Shopping malls: overnight scrubbing of common areas, with spot cleaning during trading hours.
3. Warehouses and logistics centers: dry debris collection and wet scrubbing in a single pass across large storage floors.
4. Manufacturing plants: routine floor care in production halls, using separate agent tanks for different soils.
5. Transit stations: repeat cleaning of high-traffic halls where tracked-in water is a constant problem.
6. Multi-floor commercial buildings: floor-to-floor coverage where the optional E-gate/Elevator communication is installed.

Summary

The detail that sets the PUDU BG1 apart is its refusal to make a mess worse. A machine that pulls its sweepers back from a spill is a machine designed to read conditions, and that runs through the rest of the design: Lidar + 3D VSLAM fusion positioning for reliable navigation, a choice of covered and spot cleaning modes, dual agent tanks, generous clean and waste water capacity, and an all-in-one station that handles refilling, drainage and charging without help. Some specifications, including IP rating, noise level and weight, are still to be confirmed at quotation, and Robots USA will answer them for your site. If your floors are large, busy and need cleaning every night, this page is the starting point.
