Miele Boost CX1 vs Guard M1 Cat & Dog

The Miele Boost CX1 and the Miele Guard M1 Cat & Dog perform identically on floors since they both have similarly powerful suction motors and use the same floorheads. However, the M1 is a bagged vacuum, which offers advantages over the bagless CX1. It doesn't need to be emptied as often, and emptying the sealed dirtbag is clean and hygienic. Allergy sufferers should note that emptying the bagless CX1 creates a dust cloud that will negatively affect air quality. As well, the CX1 uses an expensive replaceable filter, so the CX1 has recurring costs despite not needing dirtbags.
