Dyson Ball Animal 2 Upright Vacuum

Vacuum worked great for about 18 months. Stellar cleaning power and very maneuverable. We have 1 Golden Retriever and 3 cats, and thought this would be the hot ticket (e.g., "Animal" is in the name!) This did a great job picking up all the pet hair for 1.5 years. Now to the bad: this thing is just not designed to last. I just had to order a replacement roller brush for $50 because the bushings at either side failed (massive play and vibration). Upon disassembling the suction head, I found tons of hair and dust compacted into the joint of every rotating assembly = excessive stress/friction = premature failure. There is zero attempt to seal the mating sections that spin to guard against hair/dust intrusion. Beyond that, the bushing that failed on the roller brush is plastic, and shredded/melted (note there was massive clumps of hair in front of, inside, and behind what was left of the bushing. I have nothing against plastics, but this clearly is not the right polymer for the job on this rotating joint. I get it: nothing lasts forever. You can expect to do Preventative Maintenance or repairs on components, but at this price point, I expected more: either Dyson selling just the bushing as a wear item, or Dyson designing a better bushing (brass or higher grade plastic). My anecdotal experience with vacuums has never been to replace bushings after so little use (around 80 hours). Heck, my backup budget Hoover I bought from a department store in 2014 hasn't required any repairs yet, and that has about 4x the hours than my Dyson. TL;DR I will not be purchasing another Dyson.
