@azil the handle is available at places [https://www.amazon.com/Roomba-800-Black-Handle-801/dp/B07178W62Q|like this] The replacement will be tougher since there is not a lot of information out about it. It appears as if you have to pretty much completely disassemble it. Check something [https://www.youtube.com/watch?v=Uv0oQWvdpGk|like this] and you may need to improvise a bit.
