Cleaning machines for operational use
Guide to the selection of commercial cleaning equipment
When it comes to in-house cleaning, the right cleaning machine is the decisive factor. Whether warehouse, production area, salesroom or workshop: The wrong choice of machine leads to inefficient processes and increases the consumption of resources. When choosing the right cleaning machines, it is important to analyze the type of soiling, area size and cleaning frequency in advance and then select the right machine.
What are commercial cleaning machines?
Commercial cleaning machines are devices specially designed for industrial purposes or machines for removing soiling from large areas. In contrast to manual cleaning, they enable consistent cleaning quality and shorter cleaning times. Mechanical cleaning, for example, removes loose particles such as dust, sand or chips. Wet cleaning is required to remove adhesive dirt such as liquids or dried residues.
Operating principles of different types of cleaning machines
Scrubber-driers
Scrubber-driers combine wet cleaning and vacuuming in a single work step. Rotating brushes or pads use water and a low-foaming cleaning agent to loosen adhering dirt. A suction lip absorbs the dirty water into a waste water tank in the same operation, leaving an almost dry floor surface.
Typical technical parameters:
- Cleaning performance: approx. 1,000 - 4,000 m²/h
- Working width: 350 - 1,000 mm
- Fresh/dirty water tank: 10 - 80 liters
- Brush pressure: approx. 15 - 30 kg
Cordless walk-behind scrubber-driers with battery offer additional flexibility and maneuverability, especially for angled areas.
Depending on the machine and brush or pad type, scrubber-driers are suitable for different floor types.
Smaller machines weighing up to around 60 kg are typically used on smooth surfaces such as tiles, PVC or polished concrete. Larger machines are mainly used for more robust floors such as industrial tiles or stone surfaces.
Sweepers
Sweepers clean mechanically with rotating brushes. Their main function is to pick up loose dirt into a container. Most machines work dry and without water. However, professional machines also have a fresh water tank. The floor is sprayed with a mist using a nozzle. This prevents dust from being stirred up.
Typical technical parameters:
- Cleaning performance: approx. 1,500 - 22,000 m²/h
- Cleaning width: 1,000 - 2,500 mm
- Sweepings container: 20 - 250 liters
A manual sweeper is usually sufficient for smaller areas such as corridors or walkways. For large areas with a high volume of dirt, such as parking lots or production halls, a ride-on sweeper with a cleaning capacity of 7,000 - 15,000 m²/h is suitable. For public roads, road sweepers with a maximum speed of 6 km/h or more require road approval in Germany.
Wet-dry vacuum cleaners
Wet/dry vacuum cleaners suck up both dry dirt and liquids. They work with negative pressure and a filter system that separates dirt and air. This allows dust, shavings and dirt particles to be picked up as well as water, oil or other liquids. Industrial models are also able to remove coarse dirt such as small metal parts or debris.
Typical technical parameters:
- Container volume: 20 - 80 liters
- Air flow: 50 - 120 l/s
- Suction power: 200 - 300 mbar
Wet/dry vacuum cleaners are particularly suitable for flexible and selective cleaning tasks, for example on construction sites, in workshops or for short-term cleaning requirements. However, they are less convenient to use for large-scale floor cleaning.
Comparison of cleaning machines
While sweepers efficiently pick up loose and dry dirt, they are not suitable for sticky residues.
Scrubber dryers, on the other hand, enable thorough wet cleaning and also remove oily or dried-on dirt.
In comparison, wet/dry vacuum cleaners are not designed for area performance, but for spot applications.
Which appliance is suitable for my application?
In general, a combination of different cleaning appliances makes sense. However, depending on the type of soiling, certain machines are particularly suitable.
| Type of soiling | Suitable cleaning appliance |
|---|---|
| Dry, loose dirt | Sweeper |
| Adhesive, sticky, oily dirt | Scrubber dryer |
| Punctual soiling, liquids or leaks | Wet/dry vacuum cleaner |
Selecting the right cleaning machine
1. Determine type of soiling (dry, sticky, liquid)
2. Analyze area size
3. Determine cleaning frequency
4. Take into account the condition of the floor
5. Check power supply (battery or cable)
6. Assess space conditions and accessibility
7. Compare cost-effectiveness and time required
8. Plan a combination of several machines
Typical fault indicators
- A visible dust film indicates a lack of sweeping.
- Streaking indicates insufficient wet cleaning.
- Puddling indicates a lack of suction power.
- Long cleaning times indicate an unsuitable choice of machine.
B2B advantages of a systematic cleaning machine selection
A well thought-out selection of cleaning machines leads to more efficient processes and cleaner cleaning results.
- Reduction of cleaning times
- Reduction in operating and personnel costs
- Standardization of processes
The combination of several machine types enables a clear division of tasks within the cleaning process.
FAQ - Questions about cleaning machines and their use
Which cleaning machine is suitable for a warehouse?
For warehouses, sweepers are generally used for pre-cleaning and scrubber-driers for the main cleaning.
When is a scrubber dryer necessary?
When sticky dirt such as oil, grease or dried residues need to be removed.
Can a wet/dry vacuum cleaner replace a scrubber-dryer?
No, as it is designed for spot cleaning and not for cleaning large areas.
How can dust generation be reduced?
Before sweepers are used, the floor can be sprayed with a fine mist to prevent dust being stirred up.
What role does area coverage play?
The area performance or cleaning performance of an appliance indicates the area (m²) that can be cleaned per hour.
Which machine is suitable for small areas?
Compact pedestrian devices or manual devices such as hand sweepers are suitable for small areas.
Battery or cable - which is better?
Battery-operated appliances offer more flexibility and maneuverability, especially in areas with tight corners. Corded machines offer constant performance, even when used for long periods without intermediate charging.
Why should several machines be combined?
Different types of soiling require specific cleaning methods. A sweeper efficiently removes loose dirt, while a scrubber dryer loosens sticky residues and a wet/dry vacuum cleaner picks up liquids. The combination of different devices improves the cleaning result and makes the process more efficient overall.
Conclusion: Systematic selection instead of individual solutions
There is no universal cleaning machine for all requirements. The selection must be systematically tailored to the type of soiling, surface size and quality requirements.
Different machine types each fulfill clearly defined functions in the cleaning process. The combination of several machines increases efficiency in commercial use and improves the cleaning result.
An upstream analysis of the cleaning requirements reduces wrong decisions when purchasing and creates the basis for economical and sustainably clean cleaning results.
