Choose L40 Ultra Gen 2 if lifted mops and its standard rubber brush suit your routine: its captured listed price is $70.00 lower. Pay the L40s Ultra premium when automatic mop removal and its paired-brush design address a recurring carpet or hair-maintenance chore. We would not choose either robot for its suction rating alone.
Does Gen 2 add features that L40s lacks?

The names are not a reliable feature ladder. Gen 2 and L40s are separate configurations, and a newer-sounding label does not mean every mechanism is an upgrade. Both document an extending side brush and extending mop, so edge reach alone is not a reason to pay extra for either one.
The more useful split is the brush and what happens to the mop during carpet work. Gen 2 specifies a rubber main brush and marks mop removal as absent. L40s specifies its HyperStream DuoBrush and automatic mop removal. Those are concrete configuration differences; their practical importance depends on what your current cleaning routine leaves you doing by hand.
Will the mops stay on when cleaning carpet?
Gen 2 lifts its mops but does not automatically remove them. L40s can leave the mops at the dock for suitable vacuuming tasks. If your home mixes rugs with hard floors, the option to remove damp pads from a carpet run is a more meaningful choice than a headline suction number.
That does not guarantee a particular rug stays dry. Pile height, fringes and routing still matter. Gen 2 specifically advises avoiding fringe rugs and yoga mats. Decide which surfaces the robot should vacuum, cross or avoid, then make the relevant app settings. A robot being able to lift something is not the same as the material under it being safely clear.
For an owner whose present arrangement already works, mop removal may be a convenience rather than a necessary replacement. For a first buyer who wants separate carpet and hard-floor routines, we would put it high on the comparison list.
Which parts of dock care are included?
Both pages document heated mop washing, hot-air drying and automatic water refilling. Gen 2's standard configuration requires a separately purchased module for automatic solution adding; its FAQ states this explicitly. The large promotional phrase about automatic solution refilling should not be read as a promise that the base package includes the module.
With either tank-based station, budget space and effort for clean and used water. Gen 2's FAQ specifically says you must empty wastewater and refill the clean tank yourself. Automated pad care is valuable, but it does not make the station a permanent hands-off installation.
If a seller bundles the dispenser or an optional brush with Gen 2, compare that exact package rather than borrowing features from the bundle into a cheaper base offer. A small accessory requirement can change which offer is better without changing the robot's name.
Is L40s worth its listed premium?
The captured base references are $499.99 for Gen 2 and $569.99 for L40s Ultra, a $70.00 listed premium for L40s. These are hardware reference prices; checkout totals can change with tax, delivery or bundles. Gen 2 lists 25,000Pa versus 19,000Pa for L40s, but the larger rating cannot tell you which picks up more dirt or how often either brush needs cleaning.
For a first buyer who wants damp pads left at the dock during carpet runs, L40s offers a concrete reason to consider that premium. Its different brush system is another configuration choice, without evidence here of a measured maintenance saving. If those differences do not solve a recurring problem, choose the less expensive Gen 2: it keeps the shared extending cleaning parts and automatic pad-care functions.
For an existing Gen 2 owner, the listed difference is not the cost of upgrading. Replacing a working robot means paying for the replacement, with any resale or trade-in value considered separately. Keep Gen 2 if carpet handling and brush care are satisfactory. An L40s owner should not treat Gen 2 as an automatic successor either. Do not base a purchase on future smart-home promises: Gen 2's Matter footnote still describes an upcoming update in the captured documentation.
Which prices are being compared?
These are separate listed hardware reference prices from Dreame US store and Dreame US official store. The displayed difference is not a delivered checkout saving; tax, shipping, promotions and package details can differ.
First purchase for mixed rugs and hard floors
Consider paying the $70.00 listed premium for L40s when automatic mop removal would simplify your carpet runs or you specifically want its documented DuoBrush. If lifted pads and the standard brush suit your home, Gen 2 saves that hardware difference. Check the exact package and configure carpet handling for your rugs.
Your Gen 2 already finishes the job
Keep it when mop lifting and the standard brush are adequate. Adding a compatible dispenser for a specific detergent chore may be more relevant than paying for a whole replacement.
Frequently asked questions
Is L40 Ultra Gen 2 better than L40s Ultra?
Not across the board. The Gen 2 has the larger advertised suction rating, while L40s documents automatic mop removal and a different main-brush system. Choose the configuration that changes your routine, not the newer-sounding label.
Does Gen 2 include automatic detergent dispensing?
The base specification and FAQ say the automatic solution dispenser is a separate purchase. A bundle may include it, so verify the exact offer. Do not assume the promotional description overrides that package qualification.
Do both have extending cleaning parts?
Yes. Both document extending side-brush and mop functions. That shared capability is useful context, but it does not prove equal edge-cleaning results or justify presenting either model as the only option that reaches edges.
Should an L40s owner switch to Gen 2?
Usually there is no clear case in these documented differences. Keep L40s if it works for you. A higher suction specification alone does not demonstrate an improvement worth giving up the existing robot and purchasing another.
