The L40 Ultra can drop its mopping pads off

Underneath , the robots both have dual microfibre mopping pad which rotate to agitate and remove scandal . When carpet is discover , the pads can be raise off the primer coat to avoid soaking the fibres ( a high 10.5 millimetre , which is enough for most brusque pile carpeting ) .

The L40 Ultra has an special trick , as it can also degenerate off its wipe up pads in the moorage station . That means that the golem can move over deep - sight carpet without wet it , and it can also go on a vacuum - only run without require to take wet mop pads with it .

Edge performance is similar but the L40 Ultra has a SideReach brush

Cleverly , both automaton have a similar wipe up organization , with both using an extendable swab domiciliation that can swing out to get right to the edge of rooms .

The L40 Ultra augment this with a SideReach brush that can also extend , plan to tease junk out from the corners and edge of rooms . This makes a bigger difference on carpets ; on concentrated floors , the extendible mop stamp pad make the edge carrying into action similar with both robot .

Both use LiDAR but the L40 Ultra has better obstacle avoidance

LiDAR makes both automaton libertine at mapping , and they ’re good navigator , too , well moving from room to room and skirting around object . The sensors at the front of the L10S Ultra Gen 2 let it get cheeseparing to furniture and avoid relatively small obstacle ; however , it ’s not a camera - based system , so favorite mess , shoe and cables ca n’t be recognised and avoided .

The L40 Ultra does have a camera at the front , which allows it to easily avoid common obstacles , including the fake preferent mess that we put down .

This camera can also be used for Stain Recognition , let the L40 Ultra spot marks on the floor , give way them additional attention while cleaning .

Mopping is better with the L40 Ultra

Although both robots have a similar mopping system , the hot water washing and Stain Recognition boast on the L40 Ultra made it easily in our tests , and able-bodied to deal with our very tough ketchup dirt .

Not that the L10S Ultra Gen 2 is bad at mopping : it nab with regular scratch on the floor , and it was only for the toughest stains that we had to bring out a regular hard floor cleaner .
