In my view, the suction force is not satisfactory.
Who knows, if necessary, the problem cats: Dry food is everywhere, but not in the food bowl.
Because it happened to you that some chunks runliegen hard to reach places and you do not want to wait that they run out of himself again.
Hold the nozzle in the right direction and "clack" machts: In past our old bag sucker no problem. Then the part is gone.
Something like that I would have also presented me with this vacuum cleaner.
But do not go quite that simple: you have to aim precisely and keep the nozzle in front the cat food Chunks. Then there is also sucked.
What sounds so banal a real problem, because you can not always drankommt right and at the end with (for example) the staircase "rumkrabbelt" and try to glean these things by hand.
Conclusion: Nice unit and good to use. Suction power for us simply not sufficient enough.
Let's stay with the first marsupial :-)
