To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I ordered this to have on hand when I needed to replace these items on my Eufy Robo Vac - I pulled it out yesterday to replace a filter and the roller and it was not the correct fit. Of course, lesson learned, check the size immediately when you receive the package. Sigh...now I have to see if I can get a refund or replacement. Wish me luck!
