This vacuum is terrible, it barley can vacuum up pet hair, we bought this for the feature of being able to replace the battery, we always bought dyson vacuums previously but the batteries die after a year or two and aren’t replaceable. That being said, I’d rather buy a new vacuum every two years than use this one. Making it simple, it sucks, it goes too fast when it’s on hard surfaces, and to slow on carpets, the IQ technology does not work correctly. We will be looking for a new vacuum.
