Ask HN: Why don't robot vacuum cleaners move objects to vacuum underneath them?
Maybe they could push objects around without needing to lift them.
Of course, there's a chance this could ruin the carpet/floor.
Maybe a robot vacuum with arms that can lift objects to move them?

- krapp 4y agoBecause they're more likely to knock things over than just move them.
- gregjor 4y agoDisclaimer: not a physicist. Maybe because a Roomba weighs ~9 lbs but a sofa or table weighs 2x to 10x more. I can answer your actual question by pointing out robot vacuums lack arms or any feature capable of lifting anything. That’s “why” they don’t lift things.
