Its 720 W motor with a maximum vacuum of 222 mbar and air flow of 31 l/s guarantees constant, powerful and efficient suction, ideal for cleaning both hard floors (ceramic, marble, wood, PVC) and textile surfaces (rugs, carpets and upholstery).

The Columbus ST-11 Professional Dust Vacuum Cleaner also stands out for its class M filter with Bioneem treatment, exclusive to the brand, which acts as an anti-allergy barrier and offers additional protection to the user and the environment. This fleece filter provides superior filtration that extends the life of the equipment and ensures hygienic and sustainable cleaning. For even greater protection, it can be equipped with an optional HEPA filter, making it an excellent choice for spaces where a high level of air purity is required.

Its 11-litre fleece filter bag allows you to work longer without interruptions, reducing the frequency of emptying. In addition, the mechanical air regulation system, both in the tank and in the hand tube, allows you to adjust the suction power according to the type of surface or the level of dirt, always offering optimal performance with the least possible effort.

The 10-metre plug-in cable, which is colour-coded for safety, is conveniently stored in its rear compartment, keeping the workspace tidy at all times. The included accessories — 270 mm combination nozzle, upholstery nozzle, crevice nozzle, 2-metre hose and steel suction tube — ensure that the machine is ready for all types of applications, from carpet cleaning to furniture maintenance or hard-to-reach areas.

Its low energy consumption, advanced filtration system and ease of maintenance make the Columbus ST-11 professional vacuum cleaner a cost-effective, efficient and environmentally friendly cleaning tool.
