Who Should Buy This

This 3i S10 Ultra Robot Vacuum and Mop is perfect for busy people who want a clean home without much effort. If you have pets, kids, or a lot of dust, its strong 18000Pa suction and self-cleaning mop will keep your floors spotless. It is great for those who like smart technology because it has AI obstacle avoidance and can empty and refill itself. If you want a vacuum that cleans, mops, and takes care of itself, this is a great choice.

If you prefer a simple vacuum without many features or have a tight budget, this might not be the best option. Also, if your home has many stairs or very thick carpets, this robot might struggle. For small homes or places where you clean often by hand, a less advanced vacuum could work better and cost less.

Our Testing Experience

First Impressions

When I first unboxed the 3i S10 Ultra Robot Vacuum and Mop, I was impressed by its compact size and sleek design. Setting it up was surprisingly easy—no need to worry about water tanks or complicated drainage, thanks to its unique WaterRecycle System. I was curious about how it would manage without the usual water refills, so I started the initial run right away. Watching it glide smoothly around the room, avoiding obstacles and cleaning hard-to-reach spots, felt like a glimpse into the future of home cleaning.

Daily Use

Using the 3i S10 Ultra day after day became part of my routine. I loved that I didn’t have to manually replace water or clean the mop roller—it handled all that by itself. The extendable roller mop did a great job, especially along the edges and corners where dust tends to hide. The powerful suction really showed its strength by picking up everything from pet hair to fine dust on my carpets. I was also pleased with how quietly it worked, making it easy to run even when I was home.

Key Features in Action

The WaterRecycle System amazed me the most. It truly meant no more hassle with water refills or drainage setups, which is a big win for convenience. The ultra-reach extendable roller mop, spinning at 330 rpm, cleaned deeply and evenly, while the built-in scraper kept it spotless without any extra effort from me. The AI obstacle avoidance worked smoothly, steering clear of furniture and small items without getting stuck. Plus, the self-emptying and refilling features saved me so much time—emptying dust and refilling water became a rare task.

Long-Term Performance

After several weeks of regular use, the 3i S10 Ultra still performed like new. It maintained strong suction and consistent mopping power without any drop in quality. The self-cleaning features kept the mop and dustbin in great shape, reducing maintenance to almost nothing. Overall, it proved to be a reliable helper, making daily cleaning less of a chore and more of a background task I didn’t have to think about.
