Verdict

The Miele Boost CX1 Allergy is a compact bagless cylinder vacuum cleaner powered by an 890W motor with Vortex technology that generates an airflow exceeding 100 km/h for powerful dust pickup. Weighing 5.8 kg with a highly maneuverable 40cm x 28cm x 28cm footprint, it features an innovative TrackDrive wheel system to stay on path, a 4-stage rotary suction control, a 6.5-metre cord yielding a 10-metre operating radius, and a premium HEPA AirClean filter boasting a 99.999% fine particle and allergen retention capacity. Key advantages include its space-saving design, exceptional filtration for allergy sufferers, robust build quality tested for 20 years of use, and stable stair-parking capabilities. However, notable drawbacks include a relatively small 1-litre dust container capacity that requires frequent emptying and the potential to create a cloud of dust when releasing debris from the bagless container.
