DeWALT DWV902L

American record holder

The industrial unit for professional cleaning of the famous American manufacturer DeWALT DWV902L is a kind of champion in its class. The model, designed for class L dry dusting and water collection, stands out for its large dimensions, increased performance and a decent noise level during operation (87 dB). The 69.5x52x52cm high tower design weighs a hefty 15kg and is powered by a super powerful 1400W motor delivering 210mbar of suction power at a maximum airflow of 68L/s. For ease of movement, the vacuum cleaner is equipped with several side handles and a retractable metal handle, as well as 2 guide rollers and 2 wheels on a rubber tyre. Included with the device is a 4 m suction hose with a section diameter of 32 mm, a stepped rubber AirLock adapter for connecting the hose to a power tool, a telescopic tube. A clear disadvantage of this model is the lack of interchangeable nozzles in the kit.

Automatic filter cleaning system

The storage tank is made of durable yellow plastic, and the remaining elements of the unit are painted black. The capacity of the dust bag is 35L and the liquid collection tank is 18.4L. On the lid of the tank there is a 230 V socket for connecting a 2200 W power tool, a suction force regulator and a mode switch. During the operation of the vacuum cleaner with the tool, the automatic dust removal system is activated, which turns off with a 15 second delay to completely remove debris from the working area. The advantage of the cleaning unit is constantly high traction, which is not affected by the degree of filling of the dust collector. This is achieved by an automatic main filter cleaning system twice a minute throughout the entire period of operation. We can say that the model is recommended for harsh working conditions with construction waste and concrete dust, which most industrial vacuum cleaners cannot handle. Alas, this miracle of the American industrial industry will be very expensive.
