Self-sufficient cleaning: options for cleaning without water and electricity

Whether it’s the cleaning public spaces after a city festival, on-site cleaning of tools in agriculture or dirt removal in construction work, there are always times where cleaning is required without a direct water or electricity connection. In many cases, battery-powered devices are now the right solution, because cordless wet and dry vacuum cleaners or high-pressure cleaners for professionals are mobile, reduce trip hazards and perform very well. If it‘s a larger cleaning tasks that need to be completed without a power and water connection, high-pressure cleaners and hot water high-pressure cleaners, generators and dirt water pumps come in handy.

Removing construction dust

Poor visibility or idle work equipment are just some of the reasons for increased dust in the workplace. It’s not only a potential safety risk but also a risk for the workers’ health. Construction dust related health problems range from respiratory system irritation and inflammation to chronic lung diseases and an increased risk of cardiovascular diseases. Professional control and removal of construction dust can effectively ensure a safer environment.

Battery-powered wet and dry vacuum cleaners provide support for many jobs in the building trade. These include maintenance work on the water supply, cleaning after small water ingresses due to heavy rain or during maintenance and installation work on properties. Electricians, kitchen fitters and other tradesmen do not need to carry brooms and dustpans/sweepers when working. They can easily remove dirt with the help of vacuums. This makes self-sufficient cleaning more ergonomic and increases customer satisfaction.

Tip 1 – Easily accessible:

Battery powered wet and dry vacuums are so compact that they can be stowed in the sliding door of normal vans. From there, they can be accessed easily and are ready for use without additional setup time.

Tip 2 – Dust extraction:

A good addition to a wet and dry vacuum cleaners are cordless backpack vacuums. They make it easier to clean up dust when working with a drill or other tools.

Tip – Battery pressure washers use with low voltage:

In countries such as Japan or the USA, where less voltage is available on the power grid, cordless pressure washers offer performance comparable to cable powered models. Alternatively, a connection to an industrial power supply with a higher voltage has to be available or a device with an internal combustion engine should be selected.

Cleaning a field sprayer

Cleaning a field sprayer properly

Whether we are talking about nettle tea fertiliser and copper sulphate in biological agriculture or chemical substances in the conventional processes, when used responsibly, crop protection serves to ensure the yield of crops and to combat pests, fungi and pathogens in a targeted manner. However, when cleaning spray equipment such as a crop protection sprayer (also known as a field sprayer) between uses, it is very important to prevent product entries into the sewer system and properly remove residuals.

Cleaning restrooms and changing rooms

Cleaning restrooms and changing rooms

There are many reasons why careful cleaning is required in restroom areas: Depending on the environment, many people use toilets, shower areas and changing rooms, for example in office buildings, production facilities, hotels, restaurants, sports halls or shopping centres. In restrooms, this inevitably leads to people's skin coming into contact with various different surfaces that have been touched by practically all users – such as door handles, taps or toilet flush buttons. In this way, microorganisms can pass from one person to the next. This must be avoided by following defined cleaning sequences.

Cleaning power tools

Working effectively on a construction site requires the right tools. The accumulating dirt and dust can take its toll on equipment such as shovels, wheelbarrows and other tools. To ensure the equipment functions reliably and safely in the long term, careful cleaning and maintenance must be an essential part of the work routine. Depending on the equipment and the amount of dirt, you can use different cleaning devices, from high-pressure cleanersto vacuum cleaners.

The power spectrum of high-pressure cleaners equipped with combustion engines, capable of being powered by gasoline, diesel, or synthetic energy substitutes, exhibits a wider range of frequencies, owing to their higher power consumption. The devices deliver between 140 and 250 bar of pressure, with a flow rate of between 500 and 1.000 l/h. The running time is 6 to 8 hours, depending on the tank size, which is why longer self-sufficient cleaning tasks can be carried out easily. Thanks to their robust design, high-pressure cleaners are suitable for cleaning construction machinery before leaving a construction site, for larger cleaning operations in agricultural warehouses, or for cleaning public places after an event.

Cleaning construction equipment

The construction equipment industry is no stranger to tough and messy environments. Constant exposure to dirt, mud, clay, paint, and varnish splashes, as well as the accumulation of dried concrete, can cause significant wear and tear on expensive equipment. To ensure the longevity and value of these machines, it is crucial to implement effective cleaning measures on the construction site, in the company, and across the vehicle fleet, including construction equipment cleaning. Maintenance and repair are equally important, and cleaning plays a vital role in the upkeep of these machines. It is key to understand the importance of cold and hot water high-pressure, ultra-high-pressure technology, dry ice, and cabin cleaning. By doing so, you can help to maintain the function and value of these costly machines, thereby ensuring the success of your business.

Remove graffiti

There are many methods for graffiti removal. From hot water high-pressure cleaning to various blasting methods, the appropriate method is selected according to things such as the type of graffiti paint, the material of the substrate, and local and legal regulations. In addition, preventative options exist so that unwanted graffiti can be removed more conveniently and more gently next time.

Cleaning car parks, paths and outside areas

Whether visiting a restaurant, shopping in a supermarket, furniture store or shopping centre, or visiting a doctor or museum – often the first thing guests do on arrival is to park their car and make a short walk to a building. There are a number of methods to make a positive impression right from the start, to prevent the risk of accidents and to stop dirt being brought in from outside.

Facade cleaning

Facades can be made of many different materials such as plaster, natural stone, glass, metal or wood. They lend a building an individual appearance. To maintain their visual appeal and value for as long as possible, regular building facade cleaning is necessary. Various techniques are available, particularly when using suitable equipment such as high-pressure cleaners, sand/wet blasters and dry ice blasters, which are used professionally depending on the material and type of dirt.

Water supply and removal: wastewater pumps for self-sufficient cleaning

Wastewater pumps are used wherever water should be extracted. This can be in a flooded cellar or excavation pit. At the same time, wastewater pumps can help transport water from A to B and ensure a water supply. The pump can also be used to vacuum in water and fill tanks that supply battery-powered or combustion-engine high-pressure cleaners.
