Construction activities inevitably leave behind debris and dirt. Although manufacturers strive to endow the tool with special devices to reduce the volume of litter, it is not possible to completely eliminate its formation. This is especially true of an abrasive electrical appliance, which, although equipped with fans for dust removal, is not able to leave behind acceptable cleanliness. It is not recommended to eliminate the consequences of such events with conventional cleaning equipment, therefore, special technical means should be provided. In particular, a construction vacuum cleaner without a bag is suitable for these tasks, the design of which is designed to work with various types of garbage. This unit is available on the market in several versions, so you should initially determine the main criteria for selecting the best version.
What is special about an industrial vacuum cleaner?
Domestic dust has many differences from building dust, so the design of traditional household appliances is not suitable for harsh operating conditions. And this is not to mention the specific waste that occurs during the processing of materials. In particular, the construction vacuum cleaner is designed to work with ironshavings, cement chips, wood chips, plastic particles and even broken glass. Depending on the modification, such a device can collect dirty water without harm to its design.
But there is another significant difference between special suction devices. As already noted, modern processing tools in the form of belt grinders, electric planers and other machines provide for the possibility of supplying nozzles with dust removal systems. A construction vacuum cleaner in the appropriate modification is also suitable for the role of such an addition. With this combination, you can quickly collect dust and chips, until they scatter throughout the room.
Household appliances have a capacity of 1 to 1.4 kW. Such indicators are enough to put in order a small room after repair, but for the regular use of the unit and the collection of a large amount of heterogeneous garbage, the potential should be higher. For such needs, you will need a professional model with a power output of up to 7 kW. The power itself in this case not only determines the performance of the main function, but also the ability of the unit to perform other tasks, for example, to act as an addition to the same power tool.
But there is a downside to high power. The fact is that a construction vacuum cleaner with high performance requires an appropriate power supply. Therefore, in order to save money, it is still more expedient to work with small volumes of dust.buy entry-level models. In addition, household options are more convenient to use and less capricious in the maintenance process.
Selection according to the purpose of the equipment
As with traditional cleaning, there are two ways to get rid of construction debris - dry and wet. Work in the first mode of dirt removal is supported by almost all units of this type. However, the possibility of suction of liquids is not provided in every model. The body of such devices has a special container into which water enters, as well as waste liquid construction compounds or dirt. It should be noted that a vacuum cleaner for construction dust with the possibility of wet cleaning is undoubtedly functional, but this choice should be approached with particular care.
The fact is that working with liquids is impossible without special filters. It is desirable to give preference to polyurethane elements, since this barrier effectively performs a cleaning function and is also durable. The presence of a drain neck in the design should also be taken into account. This addition will allow you to quickly get rid of dirty liquid without disassembling the construction vacuum cleaner in order to empty the filled tank.
Optimum dust container size
In this case, models without a bag are considered, but this does not mean that the equipment is fundamentally devoid of a container for collecting dirt. An alternative is the reservoir mentioned above, which, in equipping household models, can have a volume in the range of 30-50 liters. Again, roomy.the tank allows you to collect more dust and debris, emptying less often. The characteristics of the tank directly affect the ergonomic qualities of the unit - the larger the tank, the less comfort in handling the massive body. But if you choose a construction vacuum cleaner without a bag for professional tasks, then there can be no other options - you should focus on a large and reliable tank. In this case, the capacity indicator reaches 100 liters, which significantly reduces interruptions in the cleaning process.
Developers provide two ways to clean vacuum cleaners. The first option is simpler and is usually used in inexpensive models. This is a manual method, which involves updating the tank by the user. In this case, not only the tank is cleaned, but also the filter, which should be thoroughly washed. In more advanced versions, the construction vacuum cleaner is equipped with an automatic cleaning function. This means that the user only needs to press the corresponding button, which will change the direction of the built-in valve. As a result, the vacuum cleaner uses its own air jet to clean the filter from both sides.
In the class of inexpensive devices, Metabo and Einhell models are in the greatest demand. Manufacturers do not seek to master new technologies and functions, relying on durability and performance. As the owners of such equipment note, it copes well with the main tasks, but in terms of convenience, these are not the best solutions. technology and widefunctionality is demonstrated by Bosch. In its line you can find quite affordable and powerful construction vacuum cleaner. Reviews of German bagless models note well-implemented auto-cleaning and a convenient body shape. Karcher products have similar advantages, and the list of its features includes easy access to filters, unusual design and versatility.
How to make your own vacuum cleaner?
Of course, there can be no talk of creating such a unit entirely from small details. Typically, craftsmen use the base of an old home vacuum cleaner, which is converted into a model with the makings of industrial equipment. This is done using a plastic bucket, a pipe and the necessary consumables to fix and ensure the tightness of the structure. The main work relates to the dust collector, which will be equipped with a future construction vacuum cleaner. With your own hands, this part is made from a prepared bucket. A hole is formed in it and a branch pipe is connected - in the future, this bundle is fixed to the main working unit, which forms a version of the construction dust collector. To improve performance, it is recommended to provide special filters in the design, the presence of which will extend the life of the unit.
Homemade vacuum cleaner, by the way, allows you to save a considerable amount. Modern models of this equipment are estimated at 15-20 thousand rubles. And this is not a premium level, but good household versionsKarcher and Bosch. According to the reviews of experts, a high-quality construction vacuum cleaner will help to effectively cope with the tasks of cleaning any type. The greatest difficulties are traditionally delivered by finishing events, but such a device can cope with them quickly and easily. It is enough to calculate the optimal power characteristics, tank size and functional additions. Manufacturers themselves facilitate the choice of customers by forming series for different purposes - both for domestic and professional use.
