1) That the Swivel is not suitable for heavy duty cleaning, since the rollers become matted extremely fast with a larger amount of crumbs / dirt and especially hair. A cleaning part is fortunately doing.
2) that the battery, the lt. Manual is 8h to load, then at me a normal operation on only a few (3) The magnet for attaching the suction part on style for safekeeping weak dimensioned. For me it holds at least not well.
4) etc. The edging / snare pattern ends coarser, hand knitted carpets or runners get caught in the rotating rolls, whereupon the unit shuts down.
My conclusion: For the "little dirt" in smooth bordered rugs and also for hardwood / tile very well. It is truly amazing what is there still to combed fibers. For the edges and patterns and "rougher", such as hand-knitted carpets the Swivel is not suitable.
The value is appropriate, however, does not cover my desired floor / carpet cleaning spectrum and does not replace the "normal" vacuum cleaner.
