It really isn't so much about the power as you might think. It's all about air flow. It's a bit like with amplifiers. Twice the power only gives 3db more sound
And modern vacuums simply are to small to have a proper airflow.
If you have the space you should buy one of these[^].
They never were more than 1000w but they will last you your lifetime.
That's a bit misleading. Twice the power gives twice the 'sound'. Sound pressure level has a logarithmic scale of measurement where +3db is a multiplying factor of 2. A logarithmic scale of measurement is used because the human ear is also logarithmic, automatically compensating for increases in sound pressure level so the perceived increase in loudness isn't linear.
An increase of 3db is a doubling of the SPL. It's twice as loud, although to the brain doesn't seem so, but that's a physiological phenomenon.
In my past it has been if there is an Engineering problem it's too late to fix it or it will cost too much so let the Software Engineers fix it they can make it work so we code around problems and at least make it work till the next version (hate it)
But then again " It's software that makes Hardware Happen"
I'm more concerned about the time wasted waiting for a DVD or Blu-ray player to boot up, then check for updates, and determine whether or not the licence is valid, then not allow me to press the eject button until it confirms that there's no disc in it...
These sorts of things worked just fine before they became infected with Java.
don't be so harsh, you know there are some quality goods out of china,
but out the back door of the same factory are all the below/failed spec "same same, we only change name" versions of the identical product.
(they can do quality, just that their pass yields are still not good.)
Not in my experience.
The Garmin forerunner 310xt for instance, it is a very precise device. I've extensively tested it (my running companion since 2012). The Garmin fenix 5 (far more expensive than the forerunner) might be a cool smartwatch but is a completely failure for thge runner. The distance mesurment error of 5% I experienced (meaning about 2 km in marathon) is inacceptable.
Of course the GPS is ON (and 'ready') while I am running. The tracks are actually fairly accurate, but the distance measurment is poor.
The batteries performace is within the specifications as far as I can say (I didn't focus my attention on such an aspect, yet).
