The suction power is really good, I always set him only half the strength he draws easily, sometimes larger dirt, such as small animal bedding out of my terrarium.
The only thing you can bemämgeln is that he sometimes pushes slightly larger dirt in front of him when the then but "backward" are suctioned away it goes smoothly.
For me it's still a 5 star vacuum, since the price-quality ratio is unbeatable.
From me, saying a strong buy recommendation, at least for single or 2-person households.
