as we have 100m² on one floor, no steps, etc. are present, and also any areas in which the Roomba may not have, we do not need this accessory, consequently extends the "cheapest" for us completely out.
We start the Roomba now daily in the morning until we are at home, he is happy again in his cradle, and is waiting to be emptied.
100m² are mMn the border of the Roomba's affordable. since it is readily times employs 2 hours and the battery and the garbage-collecting are all that is. Cleaning is not a problem, you can remove / remove all that garbage attracts (the receptacle, the rollers, ...). just longer hair caught happy times.
even handkerchiefs absorbs the thing - but they might get stuck quite strong, I would have here fear that the resulting partially blocked motor suffers.
we have a high pile carpet, which is not a problem, but you can tell / hear the effort :)
Interestingly, the Roomba also drive to the base of the cat tree, which is about 2 cm high.
snagging he does with us nowhere, since we have no furniture, which would cause.
Volume: loud. TV the way is not possible, so it runs at us in the morning.
Conclusion: we are absolutely delighted with the Roomba 620, and would recommend it unreservedly!
*****
and even a small note in the margin: if people are unhappy with my review, but you may comment briefly on what does not fit, so I can take into account these remarks the next time ;-)
