Applies to: Flagship: Shouhu Jia T40 Ultra

Dreame floor washer, T40 Ultra series. Intelligent AI mechanical arm for close edge cleaning of water stains; AI omnidirectional assistance; 95°C sterilizing self-cleaning.

Anti-tangle: high-molecular-weight PPA hair-cutting toothed blade. Lies flat at 180° and provides 22,000 Pa suction for cleaning under beds. AI omnidirectional assistance for smooth pushing, pulling, and turning. Quiet, constant-temperature drying in 5 minutes.

The product features an AI lifting arm designed to clean along three edges and remove water stains, with a stated lifting time of ≤0.2 seconds. The product description lists 95°C high-temperature soaking self-cleaning, a stated 100% one-pass dirt-removal rate, AI omnidirectional assistance, and coordinated combing, cutting, suction, and washing with a PPA polymer hair-cutting comb.

The product description states 5-minute quiet, constant-temperature drying and 75°C high-temperature antibacterial drying. It supports a 180° lay-flat position; the description states that suction is maintained and that backflow, leakage, and jamming are prevented. It is also described as cleaning under spaces as low as a mobile phone. Stated suction is 22,000 Pa and the stated antibacterial rate is 99.9%; the description mentions real-time electrolyzed water for antibacterial cleaning.

The product description states that the Lingbu AI mechanical arm actively cleans along three edges to remove water stains, reaching close to corners to reduce dirt and water-stain residue.

The product description states that an AI predictive algorithm identifies dirt at edges and prompts the mechanical arm to lower and collect it. The arm is described as cleaning close to edges and removing water stains. The description also states that flexible memory material adapts to the floor and responds to changes in direction.

The product description lists 400,000 lifting-arm life-test cycles, 30,000 wall and threshold impact-test cycles, and 60,000 simulated tests on different floor and tile types. It also states that water-stain removal was tested by TÜV Rheinland and that the material is an innovative synthetic material.

Designed to address a stated industry pain point: seven-stage water-control and cleaning technology, promoted as helping surfaces dry quickly without water marks.

Feature labels: an AI mechanical arm that adapts to edges and scrapes water in real time; a high-cleaning-fiber roller brush described as absorbing water quickly and in large amounts; a constant-pressure comb-tooth scraper strip that presses the bristles and squeezes out water; a polymer water-removal strip described as removing water while mopping; and a wide-spaced water inlet with strong suction.

Intelligent water-control technology uses an AI algorithm to control water volume. Stated wiping frequency: 480 times per minute.

Active multi-layer anti-tangle system: the floor head has built-in polymer PPA hair-cutting teeth that adapt in real time and precisely catch and cut hair. Combined with cyclonic suction and forward-and-reverse rotation, it coordinates combing, cutting, suction, and washing.

The comb-tooth scraper strip adapts in real time to intercept hair. The upgraded, oversized roller is designed to reduce tangling; roller diameter: 61 mm.

The product uses a PPA hair-cutting comb to help cut tangled hair.

It features a dual-wing ring airflow system and a medium-wide suction opening. The description cites 22,000 Pa suction, an 80 mm central opening, and a 160° V-shaped opening.

The high-frequency roller brush rotates in both directions: forward rotation picks up hair, while reverse rotation cleans the brush cover and gathers hair.

This flat-lay floor washer has a 180° recline design for cleaning floors while reclined.

The product description mentions suction when reclined and a base designed to avoid sticking.

Prevents backflow and keeps water out of the main motor. Separate-channel air–water separation uses vacuum negative pressure to draw air and lock in water.

Designed to prevent leaks and remove water marks during floor washing. The sealed water-locking chamber uses a submarine-inspired sealing structure. Multiple sealing materials are used, with the water inlet and outlet combined; the sealed outlet sits close to the roller brush for synchronized water dispensing, and the water path is seamlessly connected. Includes an AI noise-reduction mechanism.

Designed to resist jamming: self-cruising AI omnidirectional assistance, 360° omnidirectional wheels, and 45° wide-angle rotation.

The product has 360° swivel wheels for flexible movement and supports a 45° wide-angle pivot to help clean between furniture and in low spaces.

The page states 36% less effort and a grip force approximately equivalent to lifting two bottles of water.

The slim body is as thin as a mobile phone and can clean beneath furniture. It removes hair in one step.

Under the bedroom bed: cleans hair and cat fur. Under the living-room sofa: cleans nutshells and snack crumbs. Under the living-room coffee table and TV cabinet: cleans debris and particles without moving the furniture.

The product features AI-assisted omnidirectional movement, supporting forward and backward movement as well as turns in either direction. The page states that it uses a self-developed servo hub motor technology and performs 500 intelligent calculations and recognition operations per second.

Figures listed on the page include more than 20 algorithm iterations, over 1,000 hours of assisted-wheel operation testing, more than 700 algorithm tests, and over 100,000 push-pull and turning tests.

Dual-hub intelligent drive with real-time sensing. Smooth pushing and pulling, with 500 calculations per second to respond to subtle hand movements. Senses hand force and adjusts the speed accordingly. Predicts and slows down in advance; stops when your hand stops. Recognizes turns for smooth, responsive maneuvering.

95°C high-temperature soaking wash and a stated 100% self-cleaning rate. Three cleaning methods: soaking wash, which fully envelops and soaks to dissolve dirt; rolling wash, which imitates hand washing with tapping and scrubbing; and penetrating wash, using fine-molecule cleaning bubbles to reach into the brush fibers and carry away dirt.

Quiet drying in 5 minutes and 75°C hot-air sterilization. The product description states that it dries quietly and uses coordinated hardware and software to control temperature for constant-temperature, high-temperature drying. 600 W high-efficiency power and 5-minute rapid drying; approximately 55 dBA low noise; constant high temperature throughout and drying without disassembly; high-temperature hot-air sterilization.

Strong cyclonic suction picks up hair, particles, and wet or dry debris. High-frequency mopping helps reduce residue on the floor, while downward pressure supports scrubbing.

Suction: 22,000 Pa. Brush roller speed: 480 rotations per minute. A waterfall-style water distributor provides even water flow.

Equipped with a smart display and voice prompts. Prompts include reminders to return the unit to the base for self-cleaning, add water when the clean-water tank is low, and note when the battery level is low.

Illustrated tests and counts: lift-cycle testing of the smart lifting mechanism, 800,000 cycles; testing on different floor materials, 60,000 cycles; maximum-angle floor-brush shaft rotation testing, 60,000 cycles; floor-brush head wall-impact testing, 30,000 cycles; motor start-stop testing, 10,000 cycles; upright positioning and operation cycles, 10,000 cycles; and repeated removal from and return to the charging base, 10,000 cycles.
