In general, very happy with the purchase. For a budget of up to 20 thousand, I think this is the best copy. Height 9 cm allows you to call under the sofa and the toilet. This was important to me. Has pros: Quiet enough, overcomes obstacles well, is not afraid of black floors and carpets. Got cons: It is not very convenient to shake out the dust container. First you need to remove the filter, it is also the cover of the dust collector.
