iMartine builds a range of robot vacuum and mop combos rather than a single one-size-fits-all model. The D16S MAX is the flagship: a bagless self-emptying station holds up to 45 days of dust, 18000Pa suction and 360° LiDAR navigation map up to 5 floors, and the Tuya Smart app adds scheduling, no-go zones and voice control through Alexa or Google Assistant. The BR151 steps down to a simpler 2-in-1 dustbin and water tank with 3 suction levels and infrared obstacle avoidance, still with full app and voice control. The BR151-Geometric is the everyday entry point — 2300Pa suction, a brushless tangle-free design that's easier on pet hair, and WiFi/app control at a genuinely low price. A replacement side brush is also available for the D16S MAX, so a single worn part doesn't mean replacing the whole robot.
Real specs from iMartine's own listings, not just marketing copy.
The D16S MAX empties its own dustbin into a 2.5L base station that holds up to 45 days of dust and debris, so you're not emptying a bin after every clean.
The flagship's 18000Pa suction, with Super, Powerful, Standard and Quiet modes, is tuned to lift liquid, dust, sand, hair and even cat litter out of carpets and hard floors.
360° LiDAR and SLAM navigation build a real-time map, avoid obstacles, and remember up to 5 separate floor layouts — handy for multi-story homes.
The BR151-Geometric's brushless suction inlet is built specifically to stop pet hair from wrapping around a traditional roller brush.
Every model works with the Tuya Smart app for scheduling and zone control, and the flagship and mid-tier models add Alexa and Google Assistant voice control.
Three robot vacuum tiers and a replacement part — pick the one that matches your home and budget.
The D16S MAX is iMartine's flagship: a bagless self-emptying station holds up to 45 days of dust in its 2.5L base, while 18000Pa max suction and 360° LiDAR/SLAM navigation map and clean up to 5 separate floors. A 220ml onboard dustbin and 150ml electronic water tank with 3 water levels handle vacuuming and mopping together, with up to 220 minutes of quiet-mode runtime, ≤65dB operation, and the ability to climb 18mm thresholds. Control it through the Tuya Smart app, or with Alexa and Google Assistant voice commands.
The BR151 combines a 200ml dustbin and a 230ml water tank in one compact unit, with 3 adjustable suction levels and 2-level water control for hardwood or tile. Infrared sensors and mechanical obstacle detection guide it around furniture, it climbs 15mm thresholds and 15° slopes, and 4 cleaning modes (Auto, Spot, Edge, Zig-zag) are selectable from the Tuya app or by voice through Alexa and Google Assistant. Runtime is up to 100 minutes per charge, with auto-recharge when the battery drops to 20%.
The BR151-Geometric is iMartine's entry point: 2300Pa suction paired with a 230ml water tank for simultaneous vacuuming and mopping, and a brushless suction inlet designed specifically to stop pet hair from tangling around the roller. It runs under 65dB, climbs 15mm thresholds and 15° slopes, and is controlled through the Tuya app over 2.4GHz WiFi or Alexa and Google Assistant, with Auto, Spot, Edge and Zig-zag cleaning modes.
A direct replacement side brush for the D16S MAX. Side brushes wear down with regular use around edges and corners — swapping in a fresh one restores edge-cleaning performance without needing to replace the whole robot.

Everything the D16S MAX ships with, straight from the listing.
The engineering behind the D16S MAX.
Four power modes — Super, Powerful, Standard and Quiet — tune the 18000Pa max suction for deep cleaning liquid, dust, sand, hair and even cat litter.
The mapping system automatically recognizes and creates maps for up to 5 floors, remembering each layout so it cleans the right rooms on the right level.
Start a clean by voice, by remote, or through the app — the D16S MAX responds to whichever control method fits the moment.
Reviews below are from the BR151-Geometric listing — the only iMartine model page with reviews that genuinely describe the current product.
I bought this during Prime Day as an anniversary gift for my elderly parents. Both have mobility issues which makes using a regular vacuum difficult. It's done a great job on hard surfaces, picking up hair, fuzz, crumbs, even grass on rugs. They have three different carpet styles and it picks up decently on all of them. It does get stuck under a console and the back of the couch, but that's not a problem if you steer it away with the remote.
I honestly think this is one of the best robots on the market and it's cheap — it compares well to the expensive mapping robots. I use mine as a Swiffer mop; I added velcro with holes so I can swap pads easily. It's kept going strong for about a year, sturdy and easy to use, with an adjustable noise level. Thank you, little buddy, for cleaning up the floor and the animal messes!
It does a great job for the money. Better for small spaces. It is loud, but tolerable. The charging dock works well, but make sure you find a good place to put it. The debris collection is very small, so be sure to empty it often.
We love this! Works very well!
After researching budget-friendly robot vacuums for a few days, this one stood out with excellent reviews and a reasonable price. It picks up cat hair much better than a broom because the hair doesn't get stirred up into the air like it does when sweeping. My floors look noticeably cleaner. JUST BUY IT ALREADY!
