That's 'Trusted Reviews' where they are reviewing the individual product for a short period of time. I mean these: https://uk.trustpilot.com/review/www.sharkclean.eu And https://uk.trustpilot.com/review/sharkvacuum.co.uk
Do you mean this glowing TrustPilot review that gives it 4.5 (out of 5) star rating? The only negative I could find in the whole review was the capacity is a bit low, so more regular emptying required.
Read the trustpilot reviews. I was about to order one last week and they really put me off.
