Little Helper sucks since its acquisition day my 80 sqm apartment while I'm at work. Apart from that, he is eating now and then a sock and then stops it runs without any problems. I empty the container every 2 days, but it would also presumably rich all 3- 4 days. Not only that he keeps the apartment clean, he forces a nothing are also to a certain order, ie there must be on the ground what he can get stuck. Rugs or carpet fringes are not a problem, socks, other garments or speaker cable, however, are a problem. When the robot noted that he can not solve it stops and reports this via speakers. If you do not, however, because you have to possibly look for him in the apartment. Damage to the unintentionally sucked up things does not occur (with me until now not) as he soon as he can not get free (The robot can rotate the brush and reverse) as stops mentioned above.
All 2 to 3 weeks to clean the device in detail, gather the brush and clean the impeller. Following instructions you should do this more often but for me this is sufficient completely.
The filter (2 included) I always alternating in operation and trade them normally when cleaning the unit, the developed filter to clean then under cold water.
The robot sucks for me, not every day but every point because it is the week in use five days is this sufficient and he comes across several times over in the week so that's always super vacuumed the apartment.
Conclusion: I am super happy with the little robot and I could not do without the little helpers.
