I have an older Ecovacs and recently got the Tapo RV30 Plus

I would say get the a robot vacuum with external dust bag as my older Ecovacs model would get quite clogged after 2-3 cleaning leading to weaker suction power.

The Tapo RV30 Plus is great cause it auto suck everything into the dust bag at the dock after every cleaning session. The internal dustbin at the robot vacuum is almost fully empty so the suction power is perfect every time.

I don’t need to deal with the messy process of cleaning the robot vacuum every week after switching to this. The dust bag is super easy to replace. Only downside is the cost of replacing the dust bag every 2-3 months.

Old old Ecovacs comes with LiDAR and this new one is pretty much the same. Perhaps it’s a little faster.
