Dyson V6 : was my first stick vacuum,didn't last long Miele HX2 : awesome, until it broke(not mechanical) and needed a proprietary part. Ryobi : lots of good reviews, wife complains too bulky and roller partially working. My work around was buying 2 old school used Dyson DC models and upgrading the battery packs with aftermarket. Heaps of parts around will never buy new again IMO Dyson = Apple.
Depends on the budget. I'm going to get a Ryobi one at some point, it's $450 with a 4amp battery. I already have the batteries so that's why i'm leaning that way. Register it online and net 6 year warranty (not on battery). They don't repair they just replace. We have a Dyson V6 that doesn't last very long now. I contemplated buying battery adaptor but keen for a new unit.
Odd. We bought the big upright yellow pet edition Dyson in 2018 and it’s had zero problems so far. We also have two of the long cordless V6 Dyson and both of those have been great as well. Three Dyson’s running strong and powerful, and I always recommend them.
I was given a free Dyson v6 stick vacuum 5 years ago, I was told it had bad suction and the battery didn’t last very long. Took the whole thing apart to clean it properly, and changed the battery to be able to use a power tool battery. Still use it everyday, fully take it apart every couple months and it works great. Edit: power tool battery adapters can be found on amazon, and taking the vacuum apart was pretty easy did need an odd size t bit, I think a T8 or something.
My dc62 is a tank, still working albeit dead battery. The v8 should be similar.
This is the key. Changed mine to be able to use my DeWalt batteries. The suction is great and the battery is awesome. Easy to recharge too. The bad thing is that it's pretty heavy now and does not feel balanced while holding it.
