Just as useful as a dishwasher ...

First of all: I wanted to buy the Roomba only on Amazon, but he was right there by the dealer is not available here (Amazon had it not been in the program), so I unceremoniously where ordered differently.
Shortly thereafter, the other dealer was no longer represented here at Amazon and the sale takes place directly through Amazon. Whether one should welcome the remains to be seen.

My girlfriend was initially unenthusiastic "wievel DID YOU spent on it?!?!?!".
However, it has now become very good friends with it, practically no longer having to vacuuming.
So investment worthwhile, even if reservations made by other legitimately say Beiwohner household.

The device itself quality NiMh batteries are installed, the self-discharge rate is extremely low (I once measured about 24), so that the battery will hold all likelihood also good for 2 years. If you do not every day sucks even longer.
Unlike the manual that came Roomba must therefore NOT permanently depend on electricity, 1 to 2 weeks he comes without any significant charge losses.

The Roomba is also quite low, since the dust no longer needs to be sucked by 1,5m trunk.
The cat had initially strong fear, is approximately 1 month settling-in period, there were no more problems.

From the suction we are very excited, after every tour is the container almost full (despite almost daily vacuuming).

The docking with the charging station works pretty well, but the charging station could be designed non-slip.
The bottom threshold of the bathroom (15mm) it does not always provide for oblique journeys, but comes at some point over it.

Evtl.muss reckon with slight adaptation work in the home. For us it has always been bogged down under the toilet.
Loose cable should not lie on the floor also.

Standing Feeding reached for the Roomba, it pushes them away, water may spill over.
In the living room we have the water bowl placed betw. Sofa and flower pots, because the Roomba can not pull over.

The distance detection does not always work perfectly, sometimes it bangs against unrestrained cabinets.

Typically American: When Backward drive (in the charging station), the unit will beep.

Annoying: When loading hear a frequency whistles, because the ET department has not done their homework completely.
