> - Dyson's some batteries are notorious for killing themselves via firmware on slight cell imbalance instead of doing self-balancing. Dyson prioritize "steady income via killing good parts early" instead of "building the best vacuum possible".

Any good alternatives?

If you really want a Dyson, a better firmware: https://github.com/tinfever/FU-Dyson-BMS

If you are OK on alternatives, YouTube channel ProjectFarm has some vacuum reviews.

I went down the vacuum rabbit hole a few years ago. I decided on Sebo. These are more or less big ugly machines with a cord, but you can buy every part online no matter how small (screws, gaskets,etc) or big (motors, control boards, etc).

Riccar, Miele, SEBO. Brands you may not have heard of (I know I hadn't). Highly recommend a visit to your local vacuum repair store. Talk to the guy who's job is fixing all the shitty stick vacs.

Not to stan for Dyson, but they're not a vacuum-cleaner company, they're a fire-prevention company. Every decisionmaking process they undertake is going to have that at the top of the list. They don't want a lot of batteries in the field that are being stretched to the limits of their operating lives.

Of course, the company's best response to that concern would be to make the batteries easily replaceable, including by third-party products. But that's where job #2 comes in: make sure the consumer has to buy a new Dyson sooner rather than later.

Then why design batteries with built-in cell balancing support, and remove the resistors to disable the feature in the last moment?

You can safely say that if the battery pack's total capacity drops under 75%, disable it, or detect dead cells and take action.

Disabling life prolonging features while having a full MCU and a nice battery IC on board smells fishy to me.

I swapped to Shark and haven't looked back. Current one takes an absolute beating (masses of dog hair, kids mess, countryside dirt walked into the house etc. etc.) and still performs perfectly after 3+ years of almost daily (ab-)use

DeWalt, or any other power tool battery adapter like this: https://www.amazon.com/HICOPEET-Compatible-Motorhead-v7-v8/d...

Power tool batteries have BMS, better chargers, and if you have multiple batteries, you get infinite vacuuming powers.

Mine doesn't seem to have any problem with batteries. Just "airways blocked" error no matter what I do and the warranty/support service isn't very helpful. So I'm looking for a similar-or-better quality clone (cordless vacuum with the laser thing) but with better service.
