Dyson vacuum cleaners are generally a reliable brand, but they don’t always measure up to some of their rivals. However, most upright and cylinder Dyson vacuums come with a five-year warranty, so you can feel assured that you have protection if they go wrong within this timeframe. Even though they don’t always rank at the top of the reliability scale, many customers remain loyal to Dyson and love the other positive features of the brand.
