I bought a dreame v9 mid last year.
Been pretty happy with it, was an upgrade from a Dyson V6 and has done a good job.
One thing though is notice the battery is starting to give up. On the medium mode I used to get though a whole house as it was supposed to last an hour.
Nowadays, it probably lasts just 15-20 minutes. This is only about 18 months of using it once a week.
What has people's experience been so far? How long do the batteries last before they need replacement? And do people bother getting a replacement or just buy a new unit?
It costs 80$ for a battery and you can get a new unit for just double that.
