The unit was assembled very quickly. The technique of power has pleased me very well. The battery block is easy to see, as well as charging. In addition, is possible through the use of standard elements to replace depleted batteries independently. The removal of the dust collecting container is very easy, as well as accessibility to the brush cleaning. Only the activation of the appliance stem clamped initially, but was resolved with a little graphite quickly. The unit takes very effective in dust, hair, lint as well grobkönigere residues and can be used both on laminate, as well as carpeting very good for quick cleaning in between. Price / performance ratio excellent.
