All we have is a second hand Dyson DC34, which is really only good for spot cleaning, and my wife is getting sick of the dog hair everywhere, especially the rug and bedroom carpet (everywhere else is uncarpeted, but we'd still like to vacuum that, if that's a thing??). She knows a cleaning lady who swears by her Dyson V11, but I've briefly searched here and it seems that people in general recommend to steer away from Dyson. I would've been fine with Dyson if it was a $100-$200 thing (more towards $100 though) but the fact that we're talking about a $450+ vacuum, well I'd rather just get a more BIFL brand and model based on what I've read.

Other things I've heard about the V11 is that it's a fine secondary vacuum but not really great for your main "deep cleaning" vacuum. And considering we don't have anything great, I'd like to get something solid first, even if that means it's not a sleek cordless unit.

Any other insights or recommendations? Should we steer clear of the Dyson V11 or what are your thoughts?

Budget - $400-$500 is the number in my head, but not stuck on anything if it's BIFL and a life changer.
