Get up to 22% off 3i’s best robot vacuum and mop combos this Prime Day

While you may not be familiar with 3i yet, you'll certainly be familiar with its products. 3i is an innovative smart home brand powered by PICEA — a global leader in robot vacuum manufacturing since 2016, with a market share of over 30% in the high-end segment. With a decade of expertise, more than 1,000 patents, and 4 million units shipped annually, PICEA has been the driving force behind many top robot vacuum brands.

Now, with 3i, they're bringing that cutting-edge innovation directly to consumers. From incredible power, excellent cleaning capabilities, and a true hands-free maintenance experience, 3i's latest robot vacuum and mop combos — which include the 3i S10 Ultra, 3i P10 Ultra, and 3i G10+ — offer everything you'd want, and this Prime Day is the best time to buy them. Here's what you need to know.

3i S10 Ultra – World's first WaterRecycle™ robot vacuum and mop

The 3i S10 Ultra offers everything you'd expect from a top-tier robot vacuum and mop combo, but what truly sets it apart is its innovative WaterRecycle™ system.

Integrated into the sleek, futuristic base station, this system makes water maintenance effortless with two smart methods. The first is wastewater recycling, which gives the system its name.

It sends dirty mop water to the base station, where it's heated to 90°C and transformed into steam. This steam then passes through a condenser, cools down, and becomes distilled, sterile water. This fresh water is sent back to the robot's tank for your next cleaning session. Any leftover dirt and debris are securely collected in the base station's dust bag. 

The second method takes advantage of high-humidity environments by extracting moisture from the air. The base station automatically gathers water from the air passing through the condenser, filters it, and stores it in the robot's water tank.

The advantages are threefold. First, you won't need to worry about constantly refilling the water tank or emptying dirty water, which can be quite a chore by itself.

Second, there's no need to worry about where to place the base station, since it doesn't require plumbing connections like some other models do. And you'll save on your water bill because you use less water overall.

Of course, it's also a powerful robot vacuum and mop. Its roller mop is designed to prevent streaks, with its real-time self-cleaning feature. The mop cleans itself and adds fresh water as it mops, ensuring there are no marks or streaks left behind. It spins fast enough to tackle even the toughest stains. Spilled milk or coffee might ruin your breakfast, but it's nothing the S10 Ultra can't handle easily.

The mop extends up to 50mm along edges and baseboards, ensuring thorough coverage and a more complete clean than standard robot mops.

With 13,000 Pa of suction power, it easily picks up dust, debris, and pet hair. The anti-tangle main brush features a dual comb design that prevents tangling, even with long pet hair. And when it detects carpets, it boosts suction for a deep clean, automatically lifting the mop to protect your carpets.

And once the cleaning is done, the base station takes care of everything else, from washing and drying the mop to recycling wastewater, refilling the water tank, and dispensing detergent. Dust and debris are collected in the station's dust bag, giving you up to 60 days of use before you'll need to empty it out.

If you're after a worry-free, set-it-and-forget-it floor cleaning experience, the 3i S10 Ultra is really hard to beat. You get a truly hands-free experience, efficient water management, and cleaning, all without complex setup or manual effort.

The S10 Ultra will be available at 37% off during Prime Day (July 8 – 11). Use the special code S10USAVE5 for an additional 5% off, bringing the final price to $1139.99.

3i P10 Ultra – Outstanding value for money

The 3i P10 Ultra offers flagship performance at half the price of its competitors. That starts with its excellent mopping capabilities, featuring dual circular mops that spin at 220 RPM to mimic manual mopping, more than enough to handle even the toughest stains. The mops also automatically extend to clean tricky corners and edges, giving you complete coverage.

You'll also get industry-leading 18,000 Pa suction power that effectively picks up dust, large debris, and pet hair from deep within crevices and carpets. The anti-tangle brushes prevent hair from wrapping around them, and the TangleCut™ feature removes tangled hair when the robot returns to the base station. The P10 Ultra also automatically detects carpets, boosting suction power and lifting the mop to ensure a seamless cleaning experience.

You can also personalize your carpet cleaning preferences — whether you want to prioritize carpets, double-clean them, or skip long-pile rugs — without any manual adjustments.

The 8-in-1 base station is another highlight, packed with features you'd expect from a far more expensive robot vacuum. This includes everything from automatically washing the mop using hot water (140℉/60℃) and drying it to refilling the water tank, collecting dust and debris in the dust bag, and even cleaning the bottom tray to prevent mold and odor buildup. The 3L dust bag gives you 70 days of hands-free maintenance before it needs to be emptied.

The P10 Ultra will be available at a whopping 45% off this Prime Day. Use the special code P10USAVE5 for an additional 5% off, bringing the final price to $569.99 only.

3i G10+ – Flagship performance, entry-level price

While most modern robot vacuums feature large, multi-purpose base stations, which are necessary for a hands-free experience, they do occupy quite a lot of space, which isn't ideal for small apartments or cramped rooms. With the G10+, 3i provides a similar experience in terms of dust and debris collection, but on the robot vacuum itself.

3i's patented debris compression technology involves a mechanical paddle that actively compresses dust and debris. It allows the 1L dustbin to store up to 60 days' worth of waste, so you don't have to worry about clearing out the robot's dustbin after every cleaning cycle.

A built-in UV light disinfects the stored debris, so you don't have to worry about bacterial buildup. This compression system works silently and doesn't require disposable bags, so you won't be bothered by a noisy base station or have to spend extra on accessories.

The great news is that 3i G10+ is as impressive a robot vacuum and mop combo as its more expensive siblings, the P10 Ultra and S10 Ultra. You'll get 18,000 Pa of suction power, more than enough to handle any dust or debris and give your carpets a deep clean.

It also comes with an extendable side brush that's perfect for cleaning thoroughly along edges, sideboards, and hard-to-reach corners. Similarly, the mop pad is designed for continuous contact with baseboards and edges, providing gap-free cleaning in a single pass.

The G10+ can also build efficient and smart cleaning paths to ensure complete coverage. Utilizing dToF LiDAR, dual 3D structured light, and an AI camera, the robot vacuum can create precise 3D maps of different rooms and floors, and also recognize 128 types of objects, safely navigating around them.

If you're looking for an affordable robot vacuum and mop combo that delivers high-end performance, the 3i G10+ is the ideal choice. The G10+ will be available at 22% off for Prime Day. Use the special code G10USAVE10 for an additional 10% off, bringing the final price to $314.99.
