Where are you getting that from? Nio already have them, and they've said they're rolling out their improved 150 kWh batteries this year with other manufacturers coming in the next 2-3 years.
We have had Dysons, and sharks. Currently using Shark. Barely notice any difference.
We also have a proper plug in hoover. You need it for proper full deep hoovering, especially for carpets. The cordless extremely handy for quick day to day tidy though.
I wouldn't buy a Dyson. I was advised not to buy one at the time, I didn't listen thinking that the research I put in would justify my decision, I was wrong. Its now literally gathering dust and we have replaced it with a Miele for like 150 euro. Would never touch a Dyson again very much "fur coat no knickers". Only my opinion.
I bought a Dyson to replace Henry with cord which was a nuisance at the time . Now Dyson is in the shed ready for recycling and Henry is back on the job. The cord is not a nuisance anymore , no more replacements .
