Seamless Cleaning with a Liftable Side Brush

L40 Ultra's side brush rises over 0.39in (10mm), working with the mop and main brush to separate wet and dry cleaning tasks. The robot vacuum smoothly switches between carpets and floors, preventing mess crossover while sweeping and mopping.*10mm (0.39in): Based on tests in Dreame Lab. The lifting heighit is defined as the distance

between the top of the brush bristles and the ground after the side brush has been lifted.

L40 Ultra protects carpets from moisture by removing or lifting mops to 0.4in（10.5mm）*. You can also set zones to avoid rugs, preventing the vacuum from getting stuck. ⁤⁤To deep clean your rug, choose Suction Boost** or Intensive Carpet Cleaning Mode***.

0.4in（10.5mm）: The height difference of the robot vacuum is 0.4in（10.5mm） before and after mop lifting. For carpets with piles longer than 3mm(0.12in), we suggest you set the robot vacuum to avoid medium and high-pile carpets via the Dreamehome App and protect your carpets from getting wet.

*Suction Boost: This mode is available in the Dreamehome App. Once the carpet is detected, the robot will clean the carpet with maximum suction power. Not available under quiet suction mode.

FAQs

How do I select between Daily and Ultimate Modes?

We provide two cleaning modes to suit your needs. Daily Mode offers quick and efficient cleaning, ideal for regular maintenance. For a deeper clean, Ultimate Mode is perfect when your home needs more intensive care.

Pick the clean that fits your day.
· Daily Mode: quick, energy-saving upkeep—perfect for everyday dust, crumbs, and pet hair.
· Ultimate Mode: deeper scrub and stronger pickup when you need a reset (after parties, muddy days, shedding season).

At what point does my L40 Ultra recharge automatically?
When does my L40 Ultra recharge automatically?

Your L40 Ultra vacuum automatically returns to its base station to recharge when the battery drops below 15%, ensuring it’s always ready for the next cleaning task.

When the battery drops to about 15%, the robot returns to the base and recharges so it’s ready for the next run. If a job is still in progress, it will resume cleaning from where it left off once recharged (recharge-and-resume).

How does the DreameTech L40 Ultra manage both vacuuming and mopping functions?
How does L40 Ultra handle vacuuming and mopping together?

Your L40 Ultra is adept at transitioning between vacuuming and mopping functions without interruption. Equipped with a dual mop system, it effectively scrubs floors to eliminate dirt and stains. The mop's operation can be fine-tuned via the app, allowing you to adjust water flow settings to match the specific needs of various surfaces, ensuring that each area is cleaned appropriately.

L40 Ultra can vacuum and mop in one pass or run each task separately—your call. The dual-mop system scrubs hard floors to lift sticky stains while the vacuum path collects dry debris. In the app, adjust water level, choose Vacuum Only for rugs, and draw No-Mop Zones to protect delicate areas. Result: the right clean for every surface, without babysitting.

What should I do if I encounter a problem with the L40 Ultra?

In the event of any issues with the L40 Ultra, please reach out to DreameTech's customer service team for support. The L40 Ultra is backed by a one-year warranty, ensuring peace of mind during use. Furthermore, the mobile app contains a user guide and FAQs to expedite the resolution of minor issues.

Start with these quick wins:
1. Check the base & Wi-Fi: make sure the dock is powered and the robot is fully seated.
2. Refresh consumables: empty/replace the dust bag, rinse the filter/pads, and clear the brush.
3. Clean sensors/contacts: wipe the cliff sensors, front sensors, and charging contacts.
4. Update & retry: open the app to install any firmware updates, then start a short test clean.
