WONE Launches a Sole Cleaning Machine for Global Food Factories
WONE has officially launched the PBW-21G, a new sole cleaning machine designed specifically for food processing facilities worldwide. Featuring an extended long-bristle brush design, the PBW-21G focuses on one of the most important parts of work boot hygiene—the boot sole.
In food factories, employees' work boots come into direct contact with production floors, wastewater, food residues, grease, dust, and other contaminants. When workers move between different areas of a facility, contaminants attached to boot soles can potentially be transferred from one hygiene zone to another.
For this reason, footwear hygiene has become an important part of personnel hygiene and cross-contamination control in food processing environments. USDA FSIS guidance, for example, recognizes boot washing or designated footwear as measures that can be used to help prevent cross-contamination when moving between production areas.
With the new PBW-21G, WONE provides food factories with a compact and practical solution focused on effective sole cleaning.
Why Focus on Boot Sole Cleaning?
A work boot may look clean from a distance while dirt and residues remain inside the tread pattern of the sole.
During daily production, boot soles can collect different types of contamination depending on the industry:
- Meat and poultry residues
- Grease and fat
- Fish residues and process water
- Flour and food particles
- Mud and dust
- Wastewater and organic residues
- Dirt accumulated in sole treads
The sole is constantly in contact with the factory floor, making it an important control point in a footwear hygiene program.
For food processing plants, the objective is not simply to make footwear look clean. The cleaning process should help control the movement of contaminants between different areas of the facility. WONE's footwear hygiene guidance similarly recommends placing footwear cleaning at appropriate personnel transition points and matching the cleaning method to the contamination level.
Introducing WONE PBW-21G Sole Cleaning Machine
The PBW-21G is a boot sole cleaning machine developed for food factories that need a dedicated solution for cleaning the bottom of work boots.
The most notable design improvement is its extended long-bristle brush.
Compared with a conventional short-brush sole cleaning design, the longer brush provides a larger brushing contact area around the boot sole. As workers step onto the machine, the long bristles can reach more areas of the sole tread and help mechanically remove dirt and residues.
The design is particularly suitable for food factories where workers wear rubber boots or other work footwear with deeper or more complex sole patterns.
Key Feature: Extended Long-Bristle Brush
The long-bristle design is the defining feature of the PBW-21G.
Why does brush length matter?
A sole cleaning machine relies on mechanical brushing to loosen and remove contamination from the footwear surface. Rotating brushes combined with water and cleaning chemicals are commonly used for automated footwear cleaning in food processing environments.
By extending the brush length, WONE has designed the PBW-21G to provide a broader brushing interaction with the sole.
This makes the machine particularly suitable for applications where:
- Workers wear industrial rubber boots.
- Boot soles have relatively deep tread patterns.
- Footwear accumulates visible dirt during production.
- A dedicated sole cleaning point is required.
- Factory space is limited.
- The factory does not require full boot-side cleaning.
- A simple and focused footwear hygiene step is preferred.
The PBW-21G therefore does not attempt to replace every type of boot washer. Instead, it is designed around a specific requirement: efficient and practical sole cleaning.
PBW-21G: Designed for Food Factory Hygiene Flow
The location of a sole cleaning machine is just as important as the machine itself.
For example:
Production Area → Exit → PBW-21G Sole Cleaning → Changing Room
The appropriate position depends on the factory's hygiene zoning, personnel flow, contamination risks, and cleaning procedures.
WONE recommends evaluating personnel movement and hygiene zones before selecting and positioning footwear cleaning equipment.
More Than a Machine: Part of a Footwear Hygiene System
The PBW-21G is one component of a broader personnel hygiene strategy.
A complete footwear hygiene process may include:
Remove Dirt → Clean Boot Sole → Disinfect When Required → Dry → Store
Cleaning and disinfection should also be considered as separate steps. Heavy soil and organic residues should be removed during cleaning before an appropriate disinfection procedure is applied.
For food factories, footwear control should also be connected with hygiene zoning and personnel movement rather than treated as an isolated equipment purchase.
This is why WONE develops different types of personnel hygiene equipment for food processing facilities, from sole cleaning machines and boot washers to handwashing stations and integrated hygiene stations.
WONE PBW-21G: A New Choice for Global Food Factories
For food factories looking for a dedicated sole cleaning machine, boot sole cleaning machine, or compact boot washer solution, the PBW-21G provides a focused equipment option for controlling footwear hygiene.
WONE understands that every food factory has different production processes, layouts, hygiene zones, and personnel flows. Equipment selection should therefore be based on the actual application rather than a one-size-fits-all approach.
As a manufacturer of hygiene and sanitation equipment for food processing facilities, WONE continues to develop practical solutions for personnel hygiene, footwear cleaning, workshop sanitation, and contamination control.
