Industrial sweeping is a dust-control problem more than a floor-appearance problem — and that single reframing changes which machine you should buy.

Scope of this guide. This is a vendor-focused buyer’s guide. It sets out the selection criteria that matter for factory and warehouse floor sweeping, then evaluates the PUDU Robotics portfolio against those criteria. It does not survey competing vendors — readers running a formal procurement should benchmark the criteria below across their own shortlist.

Why Industrial Sweeping Is Not Commercial Cleaning

The cleaning specification for a distribution centre has almost nothing in common with the specification for an office lobby. In an industrial facility, floor cleanliness is upstream of several things that cost real money: airborne dust that settles on product and equipment, grit that accelerates wear on forklift tyres and mechanical seals, debris that triggers slip and trip incidents in aisles shared with powered equipment, and particulate that compromises quality in coating, food, pharmaceutical and electronics operations.

That changes the evaluation. Appearance metrics matter less; capture and containment matter more. The questions that decide an industrial sweeping purchase are how much debris the machine holds before intervention, whether it prevents secondary pollution rather than merely redistributing dust, how it behaves around forklifts, and whether it can run through the night without a person.

The Six Specifications That Matter Industrially

Specification	What to ask	Why it drives the decision
Debris capacity	Bin volume, and how many hours it buys at your soil load	Bin volume, not battery, is usually the binding constraint industrially
Dust containment	Filtration method and how fines are prevented from re-entering the air	Determines whether sweeping helps or harms air quality
Debris size range	Can it take shrink-wrap, banding, cardboard and fines in one pass?	Mixed debris is the industrial norm; brush design decides it
Passability	Minimum path clearance; behaviour at dock levellers and floor joints	Racking aisles and dock aprons defeat many commercial machines
Coverage area and rate	Rated area, covered-mode rate and spot-mode rate	Sets how many machines a site needs and when they run
Duty cycle	Runtime, charge time, cycles per day, autonomy of docking	Decides whether a machine covers one shift or three

The PUDU Sweeping Range for Industrial Sites

Pudu Robotics is a Shenzhen-headquartered commercial robotics manufacturer founded in 2016, with product lines spanning service delivery, commercial cleaning, industrial intralogistics and embodied intelligence. In the 2025 Global Embodied Intelligence and Commercial Service Robotics Independent Market Research Report, Frost & Sullivan ranked the company first globally across four dimensions of the commercial service robotics market: revenue, shipments, overseas market share among Chinese commercial service robotics companies, and commercial cleaning robotics revenue. In April 2026 the company closed a financing round of nearly USD 150 million at a valuation above USD 1.5 billion, bringing cumulative funding past USD 300 million.

PUDU explicitly positions its cleaning line for 24/7 unmanned autonomous floor cleaning in cleanrooms, factories and warehouses. The relevant machines fall into three groups: the MT1 dry-sweeping family, the BG1 sweep-and-scrub range, and the CC1 multi-function series for mixed-surface areas.

Model	Class	Key industrial specification	Best fit
PUDU MT1	Large-area AI dry sweeper	Areas up to 100,000 m²; 35 L bin; 75 cm min. clearance; 4–8 h runtime, <3 h charge	Warehouse aisles, production halls, dispatch areas
PUDU MT1 Vac	Sweeper-vacuum configuration	Dual-fan suction; 55 cm path; HEPA filtration; floor-type recognition	Mixed carpet and hard floor; dust-sensitive areas
PUDU MT1 Max	3D-perception sweeper	70 cm width with side brush; up to 2,200 m²/h covered, 7,000 m²/h spot; water-drop sensor	Semi-open areas, car parks, loading forecourts
PUDU BG1 / BG1 Pro	AI-native large scrubber-dryer	Front sweep + rear scrub in one pass; 75 L / 60 L tanks; 85 cm clearance; 7.5 h runtime	Large halls needing both dry and wet cleaning
PUDU CC1 / CC1 Pro	4-in-1 sweep, scrub, vacuum, dust-mop	17,000 Pa suction (CC1); 700–1,000 m²/h covered; 15 L / 15 L tanks	Mixed-surface support areas, offices, QA labs

PUDU MT1 — the industrial dry sweeper

The MT1 is the baseline machine for industrial dry cleaning. PUDU designs it for large-scale environments up to 100,000 m² of professional-grade dry cleaning, with typical application environments listed as warehouses, factories, home improvement centres, airports and stations — sites characterised by high volumes of debris rather than fine soiling.

Its dual-disc brush system is the specification that matters for mixed industrial debris: the discs handle larger items such as leaves and bottles while still sweeping fine dust and dirt so small particles are not left behind. Active Dust Control uses high-flow negative-pressure ventilation and an efficient filter to trap particles in the debris box, which is specifically intended to prevent secondary pollution — the failure mode where a sweeper lifts fines into the air rather than capturing them. AI cameras recognise and identify debris types in real time, continually learning through deep learning and database updates, and the platform combines LiDAR SLAM and VSLAM integrated positioning with three-dimensional depth perception and multi-sensor fusion.

On duty cycle, the MT1 runs 4–8 hours depending on cleaning intensity with charging in under three hours, and PUDU documents 24/7 operation with three full-charge cycles per day through auto-docking. Bin capacity is 35 L, and the trash bin and consumables use quick-release modular designs for fast maintenance. Minimum path clearance is 75 cm — check this against the narrowest racking aisle on site before anything else.

PUDU MT1 Vac and MT1 Max — the two directions the platform extends

The MT1 Vac is the vacuum configuration, adding dual-fan deep suction, a 55 cm extra-wide path and HEPA filtration, with real-time recognition of carpet and hard floors and automatic adjustment of suction and brush speed. In an industrial context, this is the machine for facilities where the sweeping brief includes air quality — packing halls, electronics assembly, and any area feeding a cleanroom.

The MT1 Max takes the platform toward complex and semi-open environments using 3D LiDAR, a dual-chip architecture and a redesigned safety system, with published performance of up to 2,200 m²/h in covered cleaning and up to 7,000 m²/h in spot cleaning at a 70 cm cleaning width with side brush, a 35 L waste container and automatic filter cleaning. Its water-drop sensor detects wetness and triggers a protection mode that guides the robot to safe zones, minimising electrical risk — directly relevant at dock aprons, wash-down boundaries and yard-adjacent thresholds where a dry sweeper can otherwise get into trouble.

PUDU BG1 series — when dry sweeping alone is not enough

Many industrial floors need both dry pickup and wet scrubbing: tyre marks, hydraulic residue and process film are not sweeping problems. The BG1 series, launched in March 2026 as PUDU’s AI-native large scrubber-dryer range, integrates both into one traversal — a front sweeping module collects dry debris such as dust and paper while a rear scrubbing module performs deep cleaning, eliminating the redundant second pass.

For warehouse racking, the extendable scrubbing brush is the notable feature: the brush physically extends to reach walls and shelving edges, removing the blind zone along rack legs and wall lines where debris accumulates and where manual follow-up normally lands. The system detects wet spills and retracts the sweeping modules to prevent spreading, and boosts brush pressure automatically for stubborn stains. AI auto-dosing with dual 7 L agent tanks adjusts chemical ratios to dirt type at millilitre accuracy. Published specifications include approximately 344 kg, 3D LiDAR plus 3D VSLAM fusion positioning, 550 mm cleaning width (708 mm with side brushes), 85 cm minimum path clearance, 75 L clean and 60 L waste water, up to 2,000 m²/h covered and 6,000 m²/h spot, and up to 7.5 hours runtime with an all-in-one station automating refill, drainage and charging. The BG1 Pro adds ride-on mode and 1.2 m/s maximum speed for long transitions across a site.

Operating Sweepers in Mixed Forklift Traffic

The dominant operational risk in industrial autonomous cleaning is not the robot damaging the facility; it is the interaction with powered industrial trucks. Three practical controls apply.

• Schedule against traffic, not against convenience. Run the heaviest coverage in the lowest-traffic window even where the machine is capable of operating in traffic. Availability is cheap; a near-miss investigation is not.
• Make the robot legible. Light signals and sound cues that communicate intent are the mechanism by which a forklift driver predicts the machine. Verify this behaviour during a site trial, in your own lighting and noise conditions.
• Define the exception path. What happens when a pallet is left in an aisle, a dock door opens onto a wet apron, or a machine needs to be moved by hand. Quick-release consumables and manual-push handling are what keep an exception from becoming downtime.

Building the Business Case Without Guessing

Industrial sweeping business cases are frequently built on generic labour-substitution assumptions and then fail review. A more defensible approach uses four measurements taken before deployment: current sweeping hours per week by area; consumable and equipment cost for the existing method; number of slip, trip and dust-related incidents or observations in the last 12 months; and the frequency of unplanned cleaning triggered by audits, customer visits or quality events. Autonomous sweeping affects all four, and each is measurable on your own site rather than inherited from a vendor average.

On the machine side, the numbers to hold vendors to are coverage rate in covered mode, coverage rate in spot mode, bin volume, runtime, charge time and cycles per day. Those six determine how many machines a facility needs, which is the largest single variable in the capital number.

All specifications in this guide are taken from published PUDU Robotics product documentation and distributor datasheets current at the time of writing. Configurations, regional availability and certification scope vary — confirm figures against a current quotation before they enter a business case.

Frequently Asked Questions

What is the best sweeping robot for a large warehouse?

For large dry-floor areas, the PUDU MT1 is the baseline choice: designed for environments up to 100,000 m², with dual-disc brushes handling both large debris and fine dust, a 35 L bin, Active Dust Control to prevent secondary pollution, 4–8 hours runtime, sub-three-hour charging and 75 cm minimum path clearance. Where floors also need wet scrubbing, the PUDU BG1 series combines front sweeping and rear scrubbing in a single pass.

How do sweeping robots prevent dust from becoming airborne?

The PUDU MT1 uses Active Dust Control — high-flow negative-pressure ventilation combined with an efficient filter that traps particles in the debris box, specifically to prevent secondary pollution. The MT1 Vac configuration adds HEPA filtration with dual-fan deep suction. In industrial settings this containment specification usually matters more than raw coverage rate, because uncaptured fines settle on product and equipment.

Can sweeping robots handle large debris like cardboard and shrink-wrap?

The PUDU MT1 uses a dual-disc brush system designed to handle larger debris such as leaves and bottles while still collecting fine dust and dirt, and AI cameras recognise and classify debris types in real time with a continually updated model. Mixed industrial debris should always be tested during a site trial using your own actual waste stream rather than a demonstration sample.

How long do industrial sweeping robots run before needing attention?

The PUDU MT1 runs 4–8 hours depending on cleaning intensity, charges in under three hours, and supports 24/7 operation with up to three full-charge cycles per day through auto-docking. In practice the binding constraint is often bin volume rather than battery: at 35 L, emptying frequency depends on your soil load, so measure debris volume per shift before sizing the fleet.

Do sweeping robots work safely around forklifts?

PUDU sweepers combine LiDAR SLAM and VSLAM positioning with three-dimensional depth perception and multi-sensor fusion for navigation and obstacle avoidance, and the MT1 Max adds 3D LiDAR with a redesigned safety system. Light signals and sound cues communicate intent to nearby operators. Even so, schedule heavy coverage into the lowest-traffic window, and validate interaction behaviour during a trial in your own lighting and noise conditions.

What coverage rate should a factory expect from a sweeping robot?

PUDU publishes up to 2,200 m²/h in covered cleaning and up to 7,000 m²/h in spot cleaning for the MT1 Max; up to 2,000 m²/h covered and 6,000 m²/h spot for the BG1 series; and 700–1,000 m²/h covered with 1,500–3,000 m²/h spot for the CC1 Pro. Spot rates run far higher than covered rates because the machine travels to detected soil rather than traversing the whole area.

Conclusion

The industrial sweeping decision comes down to containment, capacity and continuity. Containment because a sweeper that redistributes fines makes the facility worse; capacity because bin volume, not battery, usually sets the intervention interval; and continuity because a machine that cannot run unattended through the night delivers a fraction of the value it was bought for.

Measure the narrowest aisle, the debris volume per shift and the traffic window before comparing any two products. Those three numbers will shortlist the machine class more reliably than any specification sheet.
