Test in difficult conditions

My starting point is a somewhat winding 3 rooms, kitchen, bathroom apartment, mostly carpeting, even in the time around is a lot. So a clear challenge for the robot, I initially thought.

What the model 770 is different from the next model 780, is really just the Multiraum recognition. Only it but to take a supplement of 100 in purchase I did not want.

-Raumerkennung-

In my apartment I put Roomba so that I open all the doors of rooms and then let him go easily.
What looks after aimless driving around, its own algorithms with whom he feels his way before. So the robot recognizes my apartment as a single room and drives nicely everything.
As in my case, but everything is a bit winding, the robot will not be immediately returned to the charging station. He gropes then as long ahead until it finds it, but this may take.

Roomba manages to free himself from any predicament. If he sometimes get stuck because he is stuck somewhere, wobbles and it rotates so long until he is freed again. This works very well. Smaller edge "overruns" he, as well as slightly higher down mats.

What are not good works loose and light, rumliegende on hard floor carpets, such as in the bathroom. This he sometimes pushes to more instead of driving it. Even thick Flauschteppiche avoids the robot due to its suction technology, since it would otherwise go broke with all Velcro.
Otherwise, the robot sucks on my normal laid carpeting everything, even smoother carpets it creates quite loose.

-Reinigung-

It's amazing what the suction picks up everything. Even if I let the robot drive every day find yourself getting lots of lint dust in the container.
Using a technique that detects if it is particularly dirty, Roomba moves like a broom back and forth until the body is thoroughly cleaned.
That it works I noticed was when Roomba visibly longer Blazed at the entrance and on the floor mats. And where ever the shoes sucked be chucked Roomba noticeably longer.
A very positive point!

Just great I find how the robot drives around to chair and table legs. Or forward scans on twisty corners. It sucks thoroughly each piece of furniture.

One must note: The robot should be done regularly clean themselves! In the brush system very quickly accumulate a lot of dirt and hair that can be done quickly clean it with the supplied cleaning tool but. The filter I needed not yet to change.
All the cleaning is very easy. Two clicks and the brush out of the robots are in hand.
An accompanying DVD, by the way as a substitute for a printed manual (!), Shows that all but again exactly.

-Volume! -

Roomba is a vacuum cleaner and no traveling silencer.
However, the loudest is the drive technology. Being loud is the only, if one really stands next to it. Roomba moves in a room behind a closed door, then you almost did not hear him.
Overall I can not complain about the sound Stronger so.

-Optimal Use (in my case) -

Because of the narrow space situation I go with Roomba to something different.

His work he performs really best when I put him in a room, close the door and anmache. He realizes then that can not be reached its base and gives even a loud noise from when it's finished.
Thus, I always put it in the space of just having a suction passage necessary and use its power of the most effective.
The robot sucks the whole apartment, me that is taking too long, unless I'm not home.
The best way to naturally clean up even the soil and moves furniture possibly quite easily, so Roomba go anywhere.

-Small FAZIT

Whether as a robot now really needs everyone must decide for themselves, of course, quite clear. In my case, I find it totally useful and helpful. If only because he brings more suction power than my old vacuum cleaner! He is not as lazy as I suck at and examined every corner.
Moreover, I am totally fascinated by his robot thinking and partly clever approach.
I like him!
