The device is for a good year in our possession and will imbibe only for small objects such as crumbs around the dining table ect. used (secondary device). The suction power is at the stage MAX for a battery vacuum cleaner perfectly adequate and confident on full line, were it not for the low reliability, this battery operated vacuum cleaner would be a (nearly) super unit. The emptying of the dust container over the waste One is also relatively easy, but is associated with excessive dust, as long as you can empty the tank out directly above the trash can but this is no problem. One shortcoming is the non-return valve (shutter) to prevent the dirt on egress. This must be cleaned regularly inconvenient as you otherwise jammed and sucked particles or insects can easily egress from the dust container. Our unit is now checked for the second time by the manufacturer / repair. The first failure of the battery has been replaced, as the device sporadically failed (the "A" button is pressed and nothing happened) is. Meanwhile, the electric brush sometimes did not go ... Now the entire unit has failed and is tomorrow again to Rep. Fetched. Unfortunately this product is for this high price, and for the yet very good reputation of the company Dyson very unreliable. I'm looking forward to the time after the warranty! From my many shortcomings with regard to any purchase recommendation.
