What sets the RVM 4 Comfort Extra apart is a dock that, besides charging, washes the robot's mop. It has a 2.5 L clean water tank and a 3 L dirty water tank: clean water rinses the mop and dirty water is collected separately, so you never have to pull off a grimy cloth and wash it in the sink. The dock weighs 6 kg and measures 450 × 310 × 445.5 mm.
The robot maps your home with a LiDAR sensor and also uses a camera and a laser sensor. With the map it cleans methodically, row by row instead of at random, and finds its way back to the dock afterwards. When the battery runs low it goes to recharge on its own. The timer lets you schedule cleaning for times when nobody is at home.
15,000 Pa of suction picks up dust, crumbs and grit from the floor while the robot mops at the same time. Inside the robot is a combined dust and water container whose dirty water section holds 0.3 L. A mop and a cleaning brush for robot maintenance are included. At 100 mm tall and 350 mm across, the robot fits under furniture with more clearance than that.
The lithium-ion battery runs at 14.4 V with a capacity of 5200 mAh, and the manufacturer quotes up to 160 minutes of runtime. A full charge takes about 3 hours 50 minutes. The dock runs on 100–240 V mains power. The stated noise level is 67 dB; the robot itself weighs 3.8 kg and the complete set with the dock 9.8 kg. You control it over Wi-Fi from a cloud-connected app.
The dock is 450 mm wide, 310 mm deep and 445.5 mm high and weighs 6 kg. With a depth of only 310 mm it sits neatly against a wall, for example in the hallway or a kitchen corner. Leave a clear area in front so the robot can drive straight in. The tanks are filled and emptied by hand, so choose a spot from which it is easy to carry them to the sink.
Homes with plenty of tiles, laminate or parquet where the floor needs washing more often than once a week; people who would rather not deal with a dirty mop cloth; and anyone who trusts Kärcher cleaning equipment and wants the robot to clean on a timer while the family is at work or school.
