Powerful suction with intelligent navigation and weak battery

If one looks at Google for "Neato" and "battery", are, as "defective" Additional search "problem", "buy" and "change" proposed - making it short and to the main weakness of the device already named.

Its unique laser mapping and its structured approach coupled with an intelligent navigation raise the Neato and its more expensive "cousin", the VR100 of Vorwerk, out of the great mass of robot vacuums. Unlike the Vorwerk device but equipped in addition to a more powerful engine, a less "whooping" fan especially with modern, long-life lithium-ion batteries, has his relative unfortunately difficult with the inertia and unfailing Nickel-Metal Hydride batteries to fight.

Update September 2014:
I bought the robot in March 2014, after only five months, the batteries began in early August to significantly weaken. Visibly shrank the runtime per charge cycle within around three weeks from 65 to about 45 minutes. The end of August I allowed the robot two new battery packs TN72350 of Tensai, see my separate review for this purpose.

Unlike the original batteries, the new pack had to offer right from the beginning a term of more than one hour, the battery had to be not only "shrink", as I feared, but my apartment was from the beginning again in a single pass sucked.

Conclusion: Who is willing to invest from time to time money in new battery pack and can be seen on the missing side brush away to the Neato should increase. Otherwise, I recommend either the Vorwerk device or at least a Neato with side brush from recent Botvac series.
