    Warehouse cleaning

    It is certainly advantageous to have your material warehouse looking spick and span. This is not only true of very small storage rooms, such as those in workshops, but also applies to very large warehouses. However, occupational health and safety and the protection of warehouse material are always key issues. In particular, the floors must be clean and safe to walk on to prevent the risk of accidents caused by inadequate cleaning. Such cleaning can be carried out efficiently using individually configurable (vacuum) sweepers and scrubber driers.

    Different cleaning techniques for different types of dirt

    When transporting warehouse material from A to B, any movement made by warehouse workers, forklift trucks and floor vehicles will kick up dust. Systematically vacuuming this dust not only helps to ensure cleanliness and safety, but also protects the warehouse material and prevents it from getting dusty. Moreover, it is not uncommon to find paper scraps from torn labels or transport documents, pieces of foil or wood splinters in warehouses. You can easily remove any dust, fluff and small paper residue with a broom, a (vacuum) sweeper or a vacuum cleaner – depending on the size of the warehouse. When it comes to choosing the appropriate cleaning machines and concepts, the size of the space is a key factor.

    Sweeping in the warehouse: Safely removing dust

    Particularly when cleaning warehouses, a vacuum sweeper is preferable to a single-purpose sweeper because of the higher volumes of dust involved. During the sweeping process, the vacuum sweeper stirs up the dust with a roller brush, vacuums up the dirt using a suction turbine (fan) and then separates it via a filter system. This means that the amount of dust is reduced during the cleaning process. The fine dust filters' service life can be extended considerably by cleaning them regularly. This can be done at the push of a button or automatically, depending on the machine type.

    In addition to dust and paper residue, you can often find foil residue and packaging tapes or wood splinters from pallets on warehouse floors. This coarse dirt should be manually removed. Otherwise, there is a risk of machines becoming clogged or of material getting caught in the roller brush. This coarse dirt can be removed using a broom or litter picker.

    Tip: Dust-free working

    In order to work in as dust-free an environment as possible, there is a precisely fitting cover made of a PVC-coated linen fabric. It is stretched over the entire front area of the sweeper up to the rear wheels with a hook-and-loop fastener. The accessories therefore reduce dust dispersion even further.

    Spot cleaning in the warehouse

    For small, occasional cleaning tasks – whether on floors, on shelves or in storage rooms – a wet and dry vacuum cleaner of the appropriate size is the ideal solution since it is versatile and quickly ready for use, particularly in very small storage areas. This makes it quick and convenient to vacuum dust, water marks and spilled liquids. If you are cleaning very small storage shelves, manual equipment consisting of wiping cloths and buckets can also be used.

    Floor cleaning in the warehouse with scrubber driers

    The first thing that needs to be considered is the floor type. Small workshop warehouses often use ceramic tiles, such as fine stoneware tiles, because they are robust and have very low moisture absorption. Meanwhile, corporate warehouses and logistics centres often have industrial flooring made of screed or resilient synthetic coverings such as synthetic resin.

    Since warehouse floors can vary so greatly, there is also a variety of cleaning technologies to choose from. Two of the main criteria for deciding which technology to use are the condition of the floor and the types of dirt in the warehouse. Scrubber driers with roller technology are particularly well suited to this type of cleaning because of the large amount of coarse dirt. This is because the remaining coarse dirt can be picked up in a single operation thanks to the rollers' pre-sweeping function.

    Fine stoneware tiles are an attractive, very popular floor covering which stands out thanks to its robust and slip-resistant qualities, as well as its very low moisture absorption rate. A modern and safe design medium, it is impossible to imagine floor coverings without fine stone nowadays.

    Cleaning cement screed

    Cement screed is the most commonly used type of screed. This floor covering requires special attention when it comes to cleaning and care. This is because it not only has to withstand a considerable amount of strain, but it also needs to meet occupational safety standards at the same time. For deep, maintenance and intermediate cleaning, it therefore all comes down to selecting the right equipment.

    Learn more
    Selecting the right mechanical process (roller or disc) and the appropriate cleaning tool (pad or brush) depends on the floor covering and the type of dirt.

    As a general rule, if it does not harm the floor, an alkaline cleaning agent should be used. If you use an acidic cleaning agent, you must ensure that cement joints are pre-soaked in water so as not to damage them.

    In particular, when using scrubber driers in warehouses, you must ensure that these machines leave the floor dry. This is particularly important because the cleaned areas are often immediately walked on again or driven over by forklift trucks. It is imperative that occupational health and safety is ensured.

    Combination machines for very large warehouses: Sweeping, scrubbing and vacuuming in one machine

    We recommend using combination machines in very large warehouses with areas of over 10,000 square metres. In such areas, machines with dust suction and a filter area of up to 10 square metres are used. These machines sweep, scrub and vacuum in a single step, saving time and increasing productivity, especially when cleaning large areas. Moreover, the models with side brushes are particularly effective at removing loose dirt from walls.

    The two types of combination machines:

    Scrubber drier with pre-assembled sweeping unit

    1. Machines with a pre-assembled sweeping unit

    What sets these machines apart is the fact that they come with a pre-assembled sweeping unit which cleans the floor dry before the downstream roller brush starts wet scrubbing.

    These models work with a separate roller brush and provide excellent cleaning results. However, they have a long total length due to the addition of the pre-sweeping module (with a relatively large turning circle between shelf aisles) and dry cleaning can kick up larger amounts of dust. On the other hand, it is easy to empty the dry, collected dirt.

    2. Machines with a large roller brush head for sweeping and scrubbing

    Machines with an integrated sweeping function are referred to as having a large roller brush head. However, this equipment uses large brush diameters, some of which are 2.5 times the size of normal brush diameters, to sweep the dirt. The collected dirt is then usually discarded into a large container for high container emptying. These machines can continue sweeping automatically in scrubbing mode and also dry-sweep without water using a filter system.

    The advantage of this is that all of the dust in the warehouse is trapped by the water. However, the waste container is more laborious to clean because it contains wet dirt. On the other hand, the machine is also much more compact and manoeuvrable and does not require an additional roller brush.

    Meeting your individual requirements: Which cleaning machine is the right one for me?

    If you purchase a cleaning machine – whether a (vacuum) sweeper, a scrubber drier or a combination machine – you want the cleaning process to be comfortable, efficient and cost-effective. When deciding which machine to buy, you must consider the requirements of your warehouse, as well as criteria for the cleaning machine.

    The following table provides an overview of factors and criteria that should be considered when making any purchase.

    Storage area criteria

    Machine criteria

    Size

    Calculate the size of the storage areaAs a rule, between 30% and 50% must be subtracted from the machine's theoretical area performance = practical area performanceDiscrepancies may arise, for example, due to not travelling in a straight line or interruptions

    Theoretical area performance = metres travelled × working width when driving straight ahead per hour (Vacuum) sweeper:For small storage areas: Manually operated and push models (up to approx. 5000 m2)For large warehouses: Ride-on machines (from 5000 m2)Very narrow areas: Dry vacuum cleanersScrubber drier:For small storage areas: Compact or walk-behind modelsFor large warehouses: Ride-on scrubber driers
