To calculate the overall star rating and percentage breakdown by star, we do not 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.
Nifty vacuum but the wall mount is extremely flimsy. The accompanied attachments don't even sit properly in the wall mount. Vacuum strength is good, only small little design drawback is that the power button is too easily activated unintentionally. Other than that you're getting pretty great value for an occasional use vacuum.
