Trying to pick a robot vacuum these days is overwhelming. There are tons of brands, and figuring out which features actually work (and which are just hype) is tough, especially on a budget. So, when Mashable Senior Shopping Reporter Leah Stodart tested the relatively unknown 3i G10+ and called it the “most impressive robot vacuum under $500,” we paid attention. And right now, it’s on sale for even less.

As of Oct. 24, the 3i G10+ Robot Vacuum and Mop Combo is on sale for $269.99, down from $449.99, at Amazon. That’s a 40% discount, $180 in savings, and the lowest price we’ve seen since launch.

What makes this one stand out, especially for the price, is how it handles dirt disposal. Instead of needing one of those giant self-empty towers, the G10+ actually compacts the debris inside its own dustbin. This means you might only need to empty it every couple of months, plus the charging dock is small enough to hide under furniture. Stodart also found its mapping really smart — it uses LiDAR and could even tell which rooms were bedrooms or bathrooms based on furniture.

It’s got strong suction (18,000 Pa), uses AI to spot dirtier areas and adjust cleaning, handles carpets well, and avoids most obstacles. “The only time I really saw debris left behind was when I intentionally spilled a giant pile of rice on the kitchen floor, and the G10+ cleared about 90 percent of it in two passes,” Stodart writes in her review.

The mopping function isn’t super fancy, but it does have a little spinning edge mop that Stodart says detailed the wall where her bathroom floor and shower meet “quite well.”

It also has a livestream camera, which is rare for vacuums at this price point. “I’ve never seen one of these on a robot vacuum that costs less than $1,000, let alone $500,” she writes. “It sounds ridiculously unnecessary at first, but I know pet parents understand the appeal of being able to remotely check on their pets.”
