These were sold as a Electrolux ( eu version ) or AEG , some times even a Volta. I had one years ago( AEG here in SA), It was a pretty well built machine for its price. Our version did not have a PN though. It had a good suction ( 220v motor here ) but as their was no PN I ended up selling it.
I would get it if you like it. All that said I cannot comment on the PN and hose set up of that particular model as I have never had experience with it .
I never trust consumer reports. When was the last time you went online and wrote a report over how happy you are with your toaster or car. 90% of people dont, You only go online when your unhappy about something and while their may be many more bad Vs good reports the reality is that those bad reports make up a very small number of people who have purchased the product.
