Yes, a key part of the Dyson brand is that all of the vacuum cleaner models produced by this company are bagless. This is an integral component of the way Dysons work. Rather than simply sucking dirt and dust into a bag, Dyson vacuums make use of cyclone technology. This means that all dirt is sucked up and spirals around inside the cones within the cleaner, ending up in the dust bin that can then be easily emptied out into the trash. So, no matter which Dyson you buy, you’ll never have to worry about buying bags or changing bags again.
