Who knew a vacuum could make so much of a difference to your day-to-day? In the last five or so years, I've held little importance to the type of vacuum I have, often opting for mid-to-low range models that don't stay effective for long and end up actually costing me more in the long run.

With a 4.5 out of 5 star average from more than 23,000 reviews, this vacuum is a best-seller. Right now, it can be found for an amazing 60% off during Prime Day, reducing the price to a whopping $99 from its normal $249. With a discount this steep, there’s a fair possibility Amazon is even making a loss on the flash sale.
