Construction activities inevitably leave trash and dirt behind. Although manufacturers seek to equip the instrument with special devices to reduce the volume of litter, it is not possible to completely eliminate its formation. This is especially true for an abrasive electrical appliance, which, although equipped with dust extraction fans, is not able to leave an acceptable cleanliness. It is not recommended to eliminate the consequences of such events with ordinary cleaning equipment, therefore, special technical means should be provided. In particular, a vacuum cleaner without a bag, the construction of which is designed to work with various types of garbage, is suitable for these tasks. 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 the feature of an industrial vacuum cleaner?
Household dust has many differences from the construction, so the design of traditional household appliances is not suitable for harsh operating conditions. And this is not to mention the specific garbage that occurs in the processing of materials. In particular, the construction vacuum cleaner is designed to work with iron chips, cement chips, wood chips, plastic particles and even broken glass. Depending on the modification, such a device can also collect dirty water without harm to its design.
But there is another significant difference between special suction devices. As already noted, a modern processing tool in the form of belt grinders, electric planers and other machines provides for the possibility of supplying nozzles with dust removal systems. The construction vacuum cleaner in the corresponding modification is also suitable for the role of such an addition. With this combination, you can quickly collect dust and shavings until it is scattered throughout the room.
Power selection
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 regular use of the unit and the collection of a large amount of heterogeneous garbage, the potential should be higher. For such needs, a professional model with a power output of up to 7 kW is required. 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 flip side 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 for working with small amounts of dust, it is still more expedient to purchase entry-level models. In addition, household options are more convenient to use and less capricious in the process of maintenance.
Selection by purpose of equipment
As in the case of traditional cleaning, there are two ways to get rid of construction waste - 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 housing of such devices has a special container into which water enters, as well as waste from liquid construction compounds or dirt. It should be noted that the vacuum cleaner for building dust with the possibility of wet cleaning, of course, is distinguished by functionality, but this choice should be approached with great care.
The fact is that working with liquids is impossible without special filters. It is advisable to give preference to polyurethane elements, since this barrier effectively performs a cleaning function, and is also durable. It should be taken into account the presence of the drain neck in the structure. 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 bag capacity
In this case, models without a bag are considered, but this does not mean that the equipment is fundamentally devoid of a capacity for collecting dirt. An alternative is the tank mentioned above, which in equipping household models can have a volume in the range of 30-50 liters. Again, a capacious tank allows you to collect more dust and debris, less often to carry out emptying. The characteristics of the tank directly affect the ergonomic qualities of the unit - the larger the tank, the less comfort in handling a 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 voluminous and reliable tank. In this case, the capacity indicator reaches 100 l, which significantly reduces breaks during the cleaning process.
Cleaning method
Developers provide two ways to clean vacuum cleaners. The first option is simpler and is usually used in low-cost models. This is a manual method, which involves updating the tank by the user. At the same time, 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 click on the appropriate button, which will change the direction of the built-in valve. As a result, the vacuum cleaner cleans the filter from both sides due to its own air stream.
Manufacturer's Reviews
In the class of inexpensive devices, Metabo and Einhell models are most in demand. Manufacturers do not seek to learn new technologies and functions, relying on durability and productivity. According to the owners of such equipment, it copes well with the main tasks, but in terms of convenience, these are not the best solutions. Technology and wide functionality are demonstrated by Bosch. In its line you can find a very affordable and powerful construction vacuum cleaner. Reviews of German models without a bag mark competently implemented auto-cleaning and a convenient shape of the case. Karcher products also have similar advantages, and from the list of its features one can single out easy access to filters, unusual design and versatility.
How to make a vacuum cleaner yourself?
Of course, there can be no talk of creating such an aggregate entirely from small parts. Usually, 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, pipe and the necessary consumables to fix and ensure the tightness of the structure. The main works relate to the dust collector, which will be equipped with the future construction vacuum cleaner. With your own hands, this part is made from a prepared bucket. A hole is formed in it and a nozzle is brought in - in the future this bundle is fixed to the main working unit, which forms the 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.
Conclusion
A home-made 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 solid household versions of Karcher and Bosch. According to experts, a high-quality construction vacuum cleaner will help to cope effectively with cleaning tasks of any type. Finishing events traditionally bring the greatest difficulties, but such a device will 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 a series for different purposes - both for domestic and professional use.
