This HUVI S1 cordless vacuum is amazing! The suction is amazing, love the digital control panel and does a lot more than my current cordless vacuum. The air purification mode almost instantly impacts the quality of the air in the room and I suffer from a lot of allergies… it was like I could instantly breathe! The aroma diffuser I put some orange essential oils and it smells amazing. I must say I have to give this cordless vacuum top marks and I already own a Dyson cordless vacuum (I was looking for an upgrade). Love this item!
