A nearly perfect vacuum robot

The pros: - great job (provided that the floor is regular), powerful suction, it is not a gimmick, no need of a conventional vacuum cleaner, except for the Neato clean the filter. - Efficient travel: it hardly returns to the same place but crosses enough round trips to forget nothing, it happens to find themselves in irregular pieces, with many obstacles to overcome.
The -: - brush for hard floors leafs, is noisy, you can not listen to the radio at the same time (mixed bristle brush and strips, more effective on carpets, is much less noisy). - Construction defects are apparently common, unless I really have not had any luck: 1, received in October 2012, was a failure of random positioning laser, one that was sent to me in exchange arrived blocked by improper brush, he had to change, and with a battery that discharges quickly when idle.
Without these problems are resolved by the warranty, I would have put 5 stars. After 3 months of use I could not do without this device.
