Brian, you say you want a cordless power nozzle? Um, hello, have you not seen the Volt powerhead that Tacony has come out with? You got your wish
As for the environmental effects of bagged cleaners, I think the one thing everyone forgets here is most new bagged cleaners use HEPA Cloth bags. And those bags are made of polypropylene, which is PLASTIC, no matter how you say it! I personally think cordless cleaners would cause more environmental harm due to the batteries, but either way both types of cleaners will have some negative impact on the environment.
Now, what do I think of Dyson eliminating corded vacuums? I am not liking it at all! If they REALLY thought cordless stick vacuums is the future, they should have waited a bit longer to improve the battery technology even more. I really don't like Dyson's powerhead. I much prefer the powerhead Shark uses on their stick vacuums, just like a regular canister vacuum powerhead but made smaller for a stick vacuum, much better at deep cleaning than Dyson's powerhead. And the one thing missing in their thinking that they will NEVER be able to accomplish with their cordless stick vacuums is bin capacity. There's no way to put a huge bin like their uprights have on a cordless stick vacuum. And that's a problem, because families need that capacity to clean large, messy homes, which is why many people consider cordless stick vacuums as supplementary cleaners, NOT a replacement for a full size canister or upright vacuum. If Dyson had developed a cordless upright or canister, like LG, Riccar/Simplicity or Hoover has, that would have been better.
Plus, I think whether Dyson wants to admit it or not, I think their abandoning corded vacuums is their way of acknowledging there is no way of developing corded vacuum technology further, & their designs are maxed out & cannot be improved further. The ONLY good thing that could come from this is their competitors will steal & copy their Root Cyclone technology & improve their own vacuums.
