Model RLL51SE SKU RLL51SE_WH EAN 6979181920664
Price includes VAT.
The Dreame RLL51SE L50 Ultra AE (RLL51SE_WH) combines a robot vacuum cleaner and mop with 28,000 Pa Vormax suction, clearing dust, hair and debris from your floors while its base station looks after the mop pads. ThermoHub washes those pads in water heated to 100 °C and dries them with hot air, and its Dual Flex Arm pushes the side brush and mop out to reach deep into corners and along the skirting.
Hair is kept from wrapping round the main brush by its TriCut anti-tangle design, so brush upkeep stays light. When the robot moves onto carpet it lifts its mops as much as 10.5 mm to keep the pile dry, so rugs get vacuumed while the hard floor around them is mopped. Once a clean is over, the base station empties the robot's dust for you, which means you seldom touch it yourself.
Smart Pathfinder navigation maps each room and plans an efficient route through your home. The Dreame app lets you start a clean, tailor it and mark rugs to avoid, and a third-party voice assistant can control it as well. Docked, the robot gets its water tank refilled by itself, a single-compartment dispenser adds cleaning solution and the AceClean DryBoard washboard keeps itself clean.
Weighing 4.03 kg, the robot has a 35 cm by 35 cm footprint (width by depth). Make sure there is room for the base station: it takes up 45.7 cm of width and 34 cm of depth and is 59 cm tall. You top up and empty both of its water tanks yourself, though you can buy a water hookup kit separately to refill and drain it automatically. The box also holds a base station ramp extension plate.
