Airlift model 7 months old. Bought in Argos with extra cover. Smelt of burning. Argos won't replace if less than 12 months old. Asked to return to vax. Item came back to me from vax 'nothing wrong with it' then it blew up, sparked and turned off house power. Vax again sending label but lost in post. Plus find your own box to return in. Ask the supermarket for a box big enough for a vacuum I was told. Haven't vacuumed house for 2 weeks already 🤮 very unhappy!!!
