  • the present disclosure relates to a vacuum cleaner that comprises an optimized movement system, which enables its rotation up to 360 degrees in a free environment.
  • the definition covers all the equipment that capture particles (solid or liquid), having a body which is big enough to be comfortably and freely maneuvered by a regular user.
  • the optimized movement comprises a dimensioning the wheels (1,2), in which their diameters are larger than height of the vacuum cleaner's main body (3), preventing its contact with the ground and the body (3) to rotate around an axis (E2), which is located on the centre of the wheels (figure 6).
  • the definition covers all the used mechanism which enables the wheels (1,2) to be rotatably mounted on the vacuum cleaner body (3) without impairing its mobility. It can contain a system with shafts, ledges, fittings, spindles, bearings, docking protrusions, etc., as long as it makes it possible for the rolling equipment to function, thus allowing the conversion from linear movement to rotational movement.
