What makes warehouses special
Warehouse and logistics floors are considerably more demanding than offices or schools. Forklift traffic produces fine dust and tyre marks, on top of spilled liquids, pallet splinters and film scraps. Cleaning often has to happen in tight time slots, between shifts or during operations.
Clean floors are not just about appearance. Dust affects goods and conveyor sensors, and slippery spots are an accident risk for people and vehicles. A scrubber dryer wet-scrubs the floor, picks up the dirty water in the same pass and leaves a surface that can be walked on quickly.
Coarse debris first
Splinters, strapping and pieces of film do not belong in a scrubber dryer. Where there is a lot of coarse debris, sweeping beforehand or a combined sweeper-scrubber is worthwhile.
Floor area as the starting point
The area to be cleaned and the frequency determine the required cleaning output. A rough industry guideline:
| Area to be cleaned | Typical machine class |
|---|---|
| up to 500 m² | Small walk-behind machine |
| 500 to 3'000 m² | Mid-sized walk-behind machine |
| 3'000 to 10'000 m² | Compact ride-on machine |
| over 10'000 m² | High-performance ride-on machine |
What matters is the floor space actually accessible, not the total footprint. Densely racked halls with narrow aisles may call for a more manoeuvrable machine despite their size. Also factor in the time window: if the hall must be done in two hours, you need more output than for cleaning spread over a whole night shift.
Walk-behind or ride-on?
| Criterion | Walk-behind | Ride-on |
|---|---|---|
| Cleaning output | Small to medium areas | High, for large halls |
| Space required | Small | Larger, also for parking and charging |
| Manoeuvrability | Very high | Good, but less compact |
| Strain on operator | A lot of walking | Much more ergonomic |
| Purchase price | Lower | Higher |
| Typical use | Small warehouses, workshops, narrow aisles | Logistics centres, large warehouses, production halls |
Where large areas are cleaned daily, a ride-on machine often pays for itself through lower labour time. How quickly depends on wage costs, cleaning frequency and machine price. A simple calculation with your own figures says more than any rule of thumb.
The right working width
A common mistake is choosing too small a working width. The machine cleans well but needs unnecessarily many passes, which costs time and therefore money every day. Conversely, the widest machine is useless if it does not fit through the racking aisles.
| Working width | Typical use |
|---|---|
| 43 to 55 cm | Smaller areas, tight spaces |
| 60 to 75 cm | Medium-sized warehouses |
| 80 to 100 cm | Large halls |
| over 100 cm | Logistics centres and industrial floors |
Measure the narrowest aisles, turning areas and passages before comparing models. Remember that the squeegee is often wider than the brush deck.
Battery and floor type
Battery-powered machines have become the norm in warehouses: no exhaust, little noise, no cables to trip over. Lithium-ion batteries charge faster, allow opportunity charging and need little maintenance, which increases availability in multi-shift operations. They are, however, usually more expensive to buy than traditional lead-acid or gel batteries. Check run time per charge, charging time and space for the charging station.
- Concrete floors: robust but often very dusty, and they need sufficient brush pressure.
- Epoxy and other coated floors: clean thoroughly but gently; aggressive pads or chemicals can attack the coating.
- In general: match brushes, pads and detergents to each other and to the floor manufacturer’s specifications.
The wrong combination of brush, pad and detergent can cost a coated warehouse floor more than the machine itself.
Buying, renting and service
Buying usually pays off for regular, long-term use. Renting makes sense for trial periods, seasonal peaks or temporary projects, while leasing spreads the cost and can include service. In every case, compare the total cost over the service life, including wear parts such as brushes, pads and squeegee blades, and any battery replacement.
Questions for suppliers
- Is a demonstration on your own floor possible?
- How quickly are technicians and spare parts available in the event of a breakdown?
- Is a replacement machine provided during repairs?
- Are operator training and a maintenance contract included or optional?
- What running costs per operating hour are realistic?
Also make sure operators are trained. Many breakdowns result from clogged filters, dirty-water tanks left unemptied or incorrect dosing settings rather than from faults in the machine itself.
