The Best Robot Vacuum and Mop Combos (2026)

All four docks empty the bin, wash and dry the mop and refill water. What separates the picks is measured cleaning, wash temperature, height, clutter handling and how often the dock needs you.

01Measured pickup beats the suction number

Rated suction runs from 15,000 Pa on the C28 to 36,000 Pa on the Roborock, and the measurements ignore that order. Vacuum Wars pulled 89 percent of embedded sand from carpet with both the C28 and the Dreame and 87 percent with the S2, against a 78 percent average. The C28 and Dreame picked up 100 percent of flattened pet hair, the S2 88.5 percent, and all three wrapped 0 percent of the test hair. The Roborock has no lab numbers yet (Vacuum Wars had published only a launch report by late September 2026), though House Digest found it cleared cat litter and hair from short-pile rugs.

02Pads or roller, and what the stain scores mean

The Roborock and Dreame mop with two spinning pads. Both eufys use a roller that is fed clean water while a scraper strips the dirty water into a tank, so the mop does not carry one room's dirt into the next. On dried stains Vacuum Wars scored the Dreame 136, the C28 119 and the S2 only 82, with the S2 putting down 0.35 g of water against a 1.07 g average. Vacuum Wars' quoted averages drift between 93 and 108 as its sample grows, so compare the robots to each other. Mop lift over carpet is 28 mm on the S2 and 21.5 mm on the Dreame; the Roborock can leave its pads at the dock for carpet up to 1.81 in thick, and eufy publishes no lift figure for the C28.

03The dock decides how often you touch it

Hot water separates the tiers. The Roborock and Dreame wash their pads at 212°F and both dose detergent; the S2 washes at 140°F with electrolyzed water, doses detergent and rewashes if its dirt sensor sees a murky rinse; the C28 lists hot-air drying but no heated wash and no detergent dispenser. Drying air is 131°F on the Roborock and S2 and 95 to 122°F on the C28; Dreame states hot air without a figure. Bag life favors the Dreame: 3.2 L rated for 100 days, against 75 days for the C28's 3 L bag, 68 days for the S2 and 65 for the Roborock. The Dreame's second detergent tank for a pet-odor formula is unique here. Water is the counterweight: Android Authority refilled the Dreame's clean tank after roughly 600 sq ft, and AndroidGuys found the C28's 2.2 L tank needed attention every few days. All four docks are large: the S2's station is 26.38 in tall and the Roborock's 19.45 in deep, so plan a wall spot with clear floor in front.

04Height and thresholds are floor-plan questions

The Roborock and Dreame retract their LiDAR turrets and fit 3.13 in gaps. The S2 is 3.78 in and the C28 4.4 in; measure your lowest furniture first. Thresholds follow the same order: the Roborock is rated for 1.77 in single and 3.46 in two-step, the Dreame for 45 mm and 88 mm, and Vacuum Wars cleared a 51 mm step with the Dreame. The S2 is rated for 35 mm but cleared Vacuum Wars' 32 mm test step once in three tries, though TechRadar and Reviewed both found it climbed thresholds well at home. The C28 has no lifting chassis and no published rating; AndroidGuys saw it manage 21 mm strips. Raised transitions between rooms narrow the choice to the Roborock and the Dreame.

05Obstacle avoidance is the number for cluttered floors

Vacuum Wars' course puts 24 objects in the robot's path. The S2 avoided all 24, the Dreame 22 and the C28 15, roughly the site's average. The Roborock has no score yet, and House Digest found it has trouble seeing low-lying objects such as toys, so we would not run it on a cluttered floor. Vacuum Chef's separate course put the S2 at 71 percent.

06Consumables and coverage

Every pick uses bags and a filter; the Roborock and Dreame also use pads and detergent, the S2 a roller and detergent, the C28 a roller. The Dreame's 100-day bag is the longest interval here; the C28's smaller tank needs the most attention. On coverage, Vacuum Wars lists 256 minutes for the Roborock and estimated about 1,088 sq ft per charge for the S2, about 950 sq ft for the Dreame and about 1,190 sq ft for the C28; Basic Tutorials found the C28's 216-minute rating falls to about 123 minutes with mopping on.
