DREAME L40s Ultra RLL22SE Robot Vacuum and Mop, 19,000Pa Suction, Self-Cleaning Dock

For households that want regular floor care across hard flooring and carpets, the DREAME L40s Ultra combines vacuuming and mopping in one robot, with an all-in-one dock to handle key clean-up tasks.

Its 19,000Pa suction and HyperStream Detangling DuoBrush are designed to collect dust, debris and hair from floor gaps and carpets. The extendable side brush and mop help the robot reach further along edges as it cleans.

Choose app-based carpet care to suit the room: lift the mops for low-pile carpet, remove them to keep carpet dry, avoid carpet, or select intensive carpet cleaning or a suction boost. It can also cross obstacles up to 1.57in (4cm) high.

Key takeaways

The L40s Ultra brings vacuuming and mopping together, so routine floor maintenance does not have to mean switching between separate tools. Its DuoBrush pairs a bristled rubber brush with a TPU rubber brush to pick up debris from hard-floor gaps and carpets while helping prevent hair tangles. That makes it a practical fit for homes where dust, everyday debris and hair collect across more than one floor type.

The PowerDock helps reduce hands-on work after a clean. It empties the robot’s dust box for up to 100 days, rinses the mop pads with 167℉ hot water, dries them, refills water and cleaning solution, and washes the board. For a simpler robot that only vacuums, those dock functions and the mopping system offer a more automated approach to caring for mixed floors.

Usage tips

Use the Dreamehome App to match carpet cleaning to the room. Select mop removal to maintain dry carpets, mop lifting for low-pile carpet, or carpet avoidance where you want the robot to focus on hard flooring. For carpet vacuuming, the app also offers intensive cleaning and a suction boost. These options let you adjust the routine rather than treating every floor surface the same way.

The robot uses LiDAR navigation, with 3D and laser obstacle avoidance listed among its features. Its EasyLeap system is designed to cross thresholds, door tracks and steps up to 1.57in (4cm), helping it continue through connected areas during a cleaning run. The product is intended for indoor use and is recommended for wood, tile, marble and carpet.

Everyday use

Set the robot to handle a mix of floor care while the dock takes care of pad washing and dust-box emptying afterwards. App, remote and third-party voice control give you several ways to manage cleaning. The extendable mop and side brush are useful for reaching along edges, while the combined vacuum-and-mop format suits a regular whole-floor routine better than using a dry-only robot and then mopping separately.

Buyers highlight its cleaning, suction, ease of use and quiet operation. Feedback on navigation is mixed, with some appreciating how it moves around furniture and others finding that obstacles can affect its movement. This provides a useful point of reference when deciding how much to rely on automated cleaning in your home.

When it makes sense

The L40s Ultra makes sense for people who want one system for vacuuming carpets and maintaining hard floors, with the flexibility to choose different carpet settings and a dock that handles several post-cleaning tasks. It is especially relevant when reducing routine dust-box emptying and mop-pad washing matters as much as getting floors cleaned. For a household balancing wood, tile, marble and carpet, its combination of adjustable cleaning, extendable tools and dock-based upkeep supports a more hands-off daily floor-care routine.
