Dyson Clean+Wash Hygiene™ is the wet cleaner with no unhygienic filter. No clogging. No bacteria.¹ No bad smells emitted.¹ Unlike other machines which depend on dirty exhaust filters that accumulate sludge, bad smells, and bacteria, Dyson Clean+Wash Hygiene™'s hygienic system keeps waste in the cleaner head, so there's no clogging pipes or dirt drawn up through the machine. 84,000 microfiber filaments rapidly absorb every kind of mess, no suction needed. While the self-cleaning mechanism removes dirt and hair with every rotation. The automatic waste separation system keeps dirty water separate from dry debris for easy and hygienic disposal. The Self-clean cycle flushes the system after every use and the hot hair drying dock prevents bacteria growth and odors. Easily switch between four power modes to tackle anything from hair and debris, to sticky spills and dried-on stains. For best results, add Dyson 02 Probiotic formulation to clean water.
