Can you please let me know which one is better?
Thanks
To do that each one that replies would have to have tried them all in a proper situation. Hardly going to be the case.
and your poll has 2 questions -  which do you use?  which is better?    That makes the poll distorted.
I think between the recent threads and the answers given shows that all the machines are good. 
3 of them will collect dry debri (2 with vacs, one with collection trays), one cant.  
All of them will do a decent job at agitation.  
Your choice now on how much you want to pay for what features.
