Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Absolutely shocking. Used it once today and it felt to bits completely. And I mean bits,in half and the metal coil insides on the floor uncoild. Washing all over the dirty. Advertising as heavy duty 😂that's funny as it's now in bits in the bin. Avoid at all costs.
