ROBIT V7S PRO Robot Vacuum Cleaner

I'm not sure how long it takes but I do know that the charge does not last for very long. It's able clean a couple rooms and then it needs to go back to its home base to recharge itself.

Make sure you empty it and that the vacuum is being charged correctly. Check the remote if it needs batteries. Change outlets.

This vacuum excellent at picking up pet hair, we have a cat and it picks up cat hair that fills the dustbin.
