I have a Dyson with the ball design from like 2013, it was around $300-400 and it’s still going strong. My only complaint is it’s big and we now have more hardwood floors where we used to have carpet. It is just bulky but it works really great, it’s been used to clean at least weekly or more than that for all these years.
We've got a Dyson Small Ball and the small wheels on the head hardly turn now and they're very hard to clean. I noticed when the thing started scratching our nice jarrah floor. Completely ruined an area of it. The lid on the handle keeps falling off too. I contacted Dyson and they said they would send us a replacement head but a few days later they cancelled the order. Turns out they don't make them any more and they won't do anything else about it. We went to Kmart and bought one of their stick ones and it does the job for us. I also have an Ozito wet and dry vac for the rabbit's enclosure. My brother has a Henry and he loves it. They cost a bit but they're industrial grade. Maybe Miele is good too always used to be. I'm from the UK and 3 of my cousins worked at the headquarters so in the early days of Dyson they got us a good deal on a machine and it was plastic fantastic. Just fell apart.
My Dyson Ball that I bought in 2013 for like $600 still works well. I do have to cut my wife’s hair out from the roller. But other than that still working good. I probably won’t buy another one though. I think I’ll just buy cheaper Sharks and replace them sooner. My mother’s new shark cleaned better than the old Dyson.
I have a very old corded Dyson Animal, probably from 2010ish. It still works pretty well. I love the ball, it just made things so much easier to maneuver. Of course I am sure all of the new vacuums have something similar now so that probably isn’t a deciding factor.
I’ve got a Dyson that I bought in like 2012. Maybe earlier. I do virtually no maintenance because I’m lazy. It’s still trucking along, no problem. Edited to add: it’s lived through my long hair, my sister’s long hair, and a Great Pyrenees.
I did this, they’re anywhere from $40-$100 and is an insanely good deal for the price but you’ll need to clean the cyclone which takes a decent bit of time and patience so be aware.
If your budget is $500+ then a Dyson V15 is what matches your requirements, it's not very reliable and is fairly weak compared to corded counterparts in that price range. If you want a compromise I would go for a Dyson Animal Ball, its reliable and just needs its cyclone disassembled and cleaned every few years (takes a few hours DIY). No point in buying a weak cordless when you already have robot vacs pulling off surface debris. People on this sub love to hate on Dyson but their corded vacs honestly makes me understand the hype.
Like someone else mentioned my recommendation would be a Kenmore Intuition, your wife probably hates the idea of a bag from how they were back in the 90's/2000's - its not like that anymore lol. If you must get a bagless the Dyson Ball Animal is good, just be aware itll take a bit more maintenance than a bagged vac.
