Blocks the all processes for 3 seconds every 10 if the vacuum is offline

This was driving me nuts.
After enabling debugpy: and hacking the maximum log text length, I got this every 10 seconds.

I think the problem is that this integration uses socket instead of asyncio streams, and should therefore wrap the _send method with hass.async_add_executor_job so it doesn't block the event loop.

This would be good even if the vacuum cleaner is online, but it is particularly bad when offline as the socket has to wait for a timeout before letting the event loop thread go on.
