Warning ****
To all considering buying a dreame vacuum. Let my experience be a warning. myself and my girlfriend purchased a model earlier this year, within a month and a half the model began not connecting and being unable to clean. we emailed the support staff and were told given the status and warranty we were eligible for a “refurbished” model. we accepted thinking this was good common ground and sent our model back and sent the refurbished in return. we were sent a l40 ultra ae and when unboxed it was faulty and made a terrible noise and didn’t operate properly. we’ve now tried to contact support several times approx 6 phone calls and 8 emails to no avail, just crickets or told that they would follow up in 48-72 hours it has now been over a month. This company is appalling and seems to be sending out faulty products with lack of communication or honoring warranty. I highly advise any and all to go with a different brand and not spend their hard earned money on this con company.
