Happened to my A10 as well.. If fully charged and it shows 3 bars on the battery, when i turn on the vacuum, it will still show 3 bars, but after a few seconds it'll start to blink as if the battery is almost finishing but it would still continue to work beyond the expected time when the battery is depleting.

I dismantled everything and washed every washable component, unclogged the tube and vacuum roller and that seemed to fix the issue.

Dude have you used the latest robot? There is carpet detection, you can choose whether you want to mop the carpet or not.

As for the toys and other objects, I ask my kid to clean up. Every day before I leave my house, I make sure there is nothing on the floor. It’s easy to pick up and not let stuff lie on the floor. No 1, helps my house stay organized. No 2, easier for the robot. Now some really good ones can detect and go around small stuff like usb cables. I’m not sure mine can do that or not. My point is, it’s not a problem for me as I keep a clean floor.

Which model you're using?

I've been thinking about roborock S7/8 series.
