Don't expect one to replace vacuuming entirely - they work best as a supplement to occasional manual cleaning, especially if you have pets or lots of debris. That said, if you've got a fairly open floor plan and don't mind spending $300-500 upfront, they're genuinely convenient for keeping daily dust and crumbs down without you lifting a finger. The payoff really depends on whether you'd actually use a regular vacuum less; if you're someone who'd just skip cleaning otherwise, it's money well spent.
Robot vacuums do pull their weight if you've got hardwood or tile and don't mind running them frequently - they're genuinely great at keeping up with daily dust instead of letting it pile up! But yeah, they struggle hard with pet hair and thick carpets, so if that's your main problem, a regular vacuum is still the real MVP and no robot's gonna change that.
