different benefits The vacuum cleaner has been in use by me for three months. Before that, there was an older model vertical Dyson; these are no longer available. All subsequent observations were evaluated in light of the previous model. The vacuum is awesome! strong but not obtrusive. The new version has a nozzle with a roller for hard surfaces (laminate, tile, linoleum), which doesn't wind anything on itself and doesn't require cleaning for three months. The old version just had a nozzle with a brush, on which hair and dog hair were continuously coiled. For this hundred fat pluses, a well-planned cleaning procedure without contact with particles is provided. Longer operating hours: One payment covers two thorough cleanings of a 45 square meter unit. The nozzle rotates in all directions and is quite maneuverable. I use practically all of the nozzles: for rugs, narrow for upholstered furniture, with a soft brush (I clean the keyboard and lamp shades). Every component fits together flawlessly and connects without any squeaks. Both a battery level display and an indicator that alerts you to issues (such as the need to empty the trash can or a blockage) are included. Other drawbacks: It would be highly practical if the power button did not require persistent finger depressing. The difficulty of using a vacuum cleaner is still present; by the conclusion of cleaning, the hand becomes fatigued.
