Core performance: a floor washer that cleans floors while lying flat.

0% hair-tangling rate; four-step coordinated combing, cutting, suction and washing.

180° lie-flat cleaning reaches under beds. Claims include no loss of suction, backflow, water leakage or jamming.

All-direction assist system: dual control wheels, 360° swivel wheels and 45° wide-angle turning.

25,000 Pa cyclone suction for wet and dry debris.

95°C low-noise drying; 5-minute quick-dry and 30-minute quiet-dry modes.

Claims 99.99% removal of bacteria and viruses; 40-minute runtime; coverage up to 300 m².

The image says the PPA composite material is specially processed and describes high rigidity, precision, stability, fatigue resistance, and creep resistance under conditions including continuous temperatures of 200°C, humidity, oil, and chemical corrosion.

Active multi-stage anti-tangle system with real-time hair cutting; described as zero-tangle and maintenance-free.

The floor brush has an integrated Swiss PPA hair-cutting blade for responsive contact and precise cutting. It is paired with 25,000 Pa cyclonic suction and bidirectional scrubbing, with combing, cutting, suction, and washing working together.

Image claims: 0% tangle rate (tested by TÜV SÜD); patent certified.

A comb scraper stays in contact with the roller brush to help catch and comb through hair. The roller is 61 mm in diameter and is described as helping prevent hair tangles. The brush uses Swiss PPA cutting teeth, described as hooking and then cutting hair caught on the roller; the image also specifies 85 closely spaced teeth and a 60° “golden” angle.

Under-bed cleaning: suction is maintained to clean beneath the bed.

The main motor does not take in water. Separate gas and water paths use vacuum pressure to draw in and retain water, helping protect the motor. The page states a suction value of 25,000 Pa and describes cleaning dirt beneath the bed.

The page’s comparison states that a single-track system mixing air and water may not retain water; when laid flat, suction decreases by 20%, and wastewater backflow may allow water into the motor and affect its service life.

The clean-water tank uses a sealed water-locking structure. The page states that the filling and water outlets are combined, the outlet fits into the floor head, and the water path is seamlessly connected. It also describes five-stage water control.

The page describes dual-control wheels, 360° multidirectional wheels, and a 45° wide-range swivel design.

The page describes the product as having dual-control wheels and 360° lie-flat multidirectional wheels. It states that the wheels use low-resistance materials and that the wheel structure distributes pressure more evenly over a larger contact area, helping improve push-and-pull responsiveness.

The multidirectional wheels support movement forward, backward, and in multiple directions.

The product features a 180° lie-flat design for cleaning beneath beds. The page specifies 25,000 Pa suction and describes a zero-hair-tangling technology.

It can be used beneath beds, sofas, coffee tables, and TV cabinets. The page describes cleaning hair, pet hair, snack crumbs, and particles.

Dreame ergonomic assistance technology features dual-control wheels, 360° omnidirectional wheel rotation and a 45° wide-angle swivel for a lighter feel.

The high-efficiency, low-resistance roller is designed for smooth pushing and pulling, evenly distributed pressure and instant response. The 360° wheels allow flexible movement, while the low-profile design helps with cleaning in low spaces. The 45° wide-angle swivel helps reach areas between furniture and low corners.

The page states 95°C low-noise drying, 95°C hot-air sterilization, a low noise level of 63 dB(A), and a 99.99% sterilization rate.

The page states a drying noise level of 63 dB(A) and says the roller brush withstands washing at 100°C without easily deforming. It also describes Dreame's patented 720° high-frequency forward-and-reverse roller-brush rotation.

The roller brush uses full-coverage soaking and cleaning, with repeated hot-water beating and forward-and-reverse rotation. The page states 95°C high-temperature soaking wash.

Powerful suction removes hair, particles, and dry and wet debris. High-frequency floor scrubbing cleans quickly and helps prevent water marks from remaining.

480 scrubs per minute; 20 N of downward pressure for scrubbing that imitates hand cleaning.

Dreame floor washer: picks up wet and dry debris in one pass. Other floor washers: repeated passes may still leave debris behind.

The page describes a wastewater-tank antibacterial deodorizing stick that helps suppress odors, and states that the tank is less likely to smell even if wastewater is left in it for seven days. The stick contains natural active substances that neutralize and break down odors in the wastewater tank and inhibit bacterial growth. The page states: odor prevention for 7 days, an antibacterial rate greater than 99.9%, and antibacterial action lasting 90 days; it also labels the product “safe and non-toxic” and “certified non-toxic if orally ingested.”

The stated mechanism has three steps: oxidizing biological molecules inside bacteria to damage cell structures and deactivate them; zinc oxide reacting with water to generate active oxygen that neutralizes and breaks down odor molecules; and active substances in high-density particles being evenly distributed and released continuously from the inside out.

The page describes one-touch, full-system self-cleaning, including water-tank cleaning to help suppress odors. Functions include electrolyzed-water preparation for bacteria removal; soaking the roller brush and the base for bacteria removal; high-temperature soaking of the base; forward-and-reverse roller-brush washing; a constant-pressure comb scraper for removing dirt; reverse rotation of the roller brush to clean its cover; recovery and suction of dirt; high-speed centrifugal drying of the roller brush; low-noise, high-temperature drying; and antibacterial deodorizing by the wastewater-tank deodorizing stick.

During floor washing, tap water is automatically converted into electrolyzed water, ready for immediate use. The page states a 99.99% bacteria removal rate and a 99.99% virus removal rate. The listed bacteria include Escherichia coli, Staphylococcus aureus, cocci, and Candida albicans; the listed viruses include influenza A virus, human coronavirus, and enterovirus.

The page describes electrolyzed water as being used to remove bacteria and viruses, for greater peace of mind in the home environment.
