Why are cockroaches so unbelievably hard to suck up sometimes?

[Menzue]

there are times where its just like zoop zoop and the nest is gone, then theres others where its like theres a single cockroach left on this wall and its not letting me suck him up so im just walking back and forth trying repeatedly to get this damn bug off the wall.

Lol @ zoop zoop, and sometimes turning left or right while standing in the same spot helps, just in case ya didn't try that. I think that sometimes we all go thru that, I've always chalked it up to a bit of lag, but who knows. Quite often I've noticed you have to be beyond them a little and then turn a bit to 'suck em up the vacuum'.... but yah, you're doing the same the rest of us do I believe, I don't reckon there is a trick to getting em up the vacuum, I've turned them to glass shards, cuz I hate bugs and I hate that crawly sound. No sound any more with the glass shards. You can do that in settings. Good luck... zoop zoop!!! :-)
