Verdict
A glorious golem void cleansing agent and mop , the Dreame L40 Ultra has a huge amount of sucking power , and can swipe or drop its swab tablet to work with any type of carpeting . Using hot water and detergent , the pout organisation can deal with very tough smirch , although the selection of 32 choice of pee levels is a bit overkill . Vacuuming is excellent , bar the occasional navigation mishap , while the AI camera on the front helps the robot spot and target stains , and avoid common obstacle .
Pros

Key Features
Introduction
Although credibly better be intimate for its more budget - concentrate automaton vacuum cleaners , the Dreame L40 Ultra is a step up in terms of features for the company .
extendible side brushes and swab , AI - powered seafaring , lots of suction and red-hot piss mop cleaning make this one of thebest all - around automaton vacancy and mopsthat I have review .
Design and features
As is come more common , the Dreame L40 Ultra comes with a self - empty , ego - clean tying up post . This has a 4.5 - liter fresh body of water tank for cleaning the mop pad and filling the golem ’s H2O reservoir and a 4 - litre tank for dirty body of water . There ’s an optional Water Hookup Kit , so you may connect the dockage station to your mains urine and drains for amply automatic usance .
Unusually for a robot at this Mary Leontyne Price , there ’s also a solution tank car that take Dreame ’s cleaning solution , which assist boost cleaning operation and is used for sanitising the mops and wash pack of cards . I normally only see cleaning solutions as an choice on more expensive models , such as theRoborock S8 MaxV Ultraor theEufy Omni S1 Pro .
There ’s a 250ml bottle of clean resolution in the box , with permutation 1 - liter bottles cost £ 12.99 .
This dock also takes 3.2 - litre dust bags that clip in next to the detergent tank . These are very large , so you should n’t have to supercede them for at least two months of steady use . Replacements cost £ 14.99 for a pack of three .
The robot itself looks much like any other golem cleaner , although this one is packed out with the later applied science . LiDAR is used for sailing , but there ’s also a camera at the front , which is used for dirt signal detection and obstacle avoidance .
open up up the top and there ’s a small 300ml bin inside the robot . You wo n’t have to empty this yourself , but it ’s worth removing once a calendar month so that you may clean the bank identification number out properly , and wash the filter to preserve maximum sucking power .
There are dual microfibre pad of paper on this robot , which birl to shake up and remove grime . As you ’d gestate , these mop pad can uprise off the background for rug avoidance .
There ’s another antic : the mopping pads can be drop off completely , which lets this robot tackle rich pile carpet without the threat of getting them blind drunk . The only other automaton vacuity cleansing agent that I ’ve seen that can deteriorate its pad off or lift them is theSamsung Bespoke Jet Bot Combo AI+ 3 - in-1 Cleaning VR7MD97714G.
Dreame uses 65 ° vitamin C water for washing the pads , which helps clean them more soundly and eliminates scent , and it means that the golem die out with hot pads for cleaning . Pads are wash at regular intervals , so this robot can keep clean house without protrude to smear grease around . Hot aura drying also helps prevent bacteria and odour soma - up .
There ’s a standard floor copse but Dreame also furnish its TriCut exemplar that transport hair into the bin to foreclose tangling . If you live in a home with pets or people with long pilus , the TriCut brush is what you need .
A SideReach copse is also there . This can extend to tease crap out from corners and edges .
command of the Dreame L40 Ultra is via the Dreamehome app . It does n’t take long , following the wizard , to get the robot connect to Wi - Fi and ready to go out for a mapping run .
Once done , the app has a guess as to where rooms are , but you’re able to unify and split a map to become the layout of your home .
As well as basic rooms , I could add piece of furniture to the map , which can make houseclean up easier : I could select a dining tabular array , for lesson , to just have the robot neat around that .
As you ’d expect , there are also no - go and no - swob zone , so you could prevent the Dreame L40 Ultra from going where you do n’t require it .
There ’s also an option to add the flooring eccentric to a room . Select horizontal or vertical floor types for hard floors , and the robot can be set to clean along the direction of the floor , to deep clean and get crap that could get trapped between crack otherwise .
After the first clean , the app will evoke adding rug zones . However , I found this a spot over - the - top , as selecting the default choice covered the function with carpet , and prevented the robot from pout my unvoiced storey areas . I found that I did n’t need to add carpeting to the map , relying on the golem ’s built - in carpet sensing .
For carpets , the nonremittal option is to raise the mop when vacuum , but you could set it to remove the mop pads instead . With the raising choice selected , the Dreame L40 Ultra will still neglect its mopping lodgings off when in emptiness - only modality .
There ’s also control condition over SideReach , which lets the golem swing out its side brushwood , and MopExtend , which is similar but for the mop pad . With MopExtend , the golem can be tell to utilise this swob for gap ( reaching under furniture , such as fridges , that the L40 Ultra ca n’t physically get under ) , and there ’s an option for intensively cleaning around article of furniture pegleg .
As the Dreame L40 Ultra has a television camera for detecting and avoiding common obstacle , you’re able to also choose to remotely view the feed . This requires physically change state the feature on by tapping the automaton ’s Home button three prison term , and set a PIN for security .
As the photographic camera is so scummy to the floor , you do n’t see much of what ’s go on , but it could be a ready to hand feature if you need to check on your house while away .
For cleaning , you may select to make clean the integral rest home , a specific way ( or room ) , or line zone on the map . The default option is to use CleanGenius , where the golem intelligently optimize suction and mopping based on penury .
This can be used in tandem with the car - recleaning modality , where the Dreame L40 Ultra will return to heavily soiled areas to give them a second clean . This feature is very useful , as you do n’t have to manually post the automaton out again .
Alternatively , you’re able to pick out the configurations manually , with a selection of vacuum , mop , vac & mop , mow after vac , and tradition room configurations , which lets you set the cleanup musical mode per room .
With these options , you get a choice of suck mode ( quiet , standard , turbo and max ) , and a choice of wetness for the mop . There are 32 wetness place setting , which frankly feels too much , and simpler options would have been preferred .
For most modes , there ’s a choice of fast or standard routing , but with the mop mode , you also get intensive and mystifying mode for even deep mopping .
There ’s also a feature for Stain Recognition , where the automaton use its television camera to detect soft touch on the flooring , where the golem will intensively mow any marker that it has fleck . This is well worth turning on .
Performance
I start the Dreame L40 Ultra with my received carpet test , adding a teaspoonful of flour to my test carpet . Using the vacuum - only setting to start out , with two passes , I line up that the robot managed to clean practically everything . Only on a very stuffy inspection could I see a duo of trace amounts of junk left behind . Clearly , the golem ’s 11,000pa suction baron process well .
punishing trading floor vacuuming was perfect , with the Dreame L40 Ultra able to piece up all of my flour spills with just a single liberty chit .
With vacuuming musical mode , the initial border fresh run was n’t so telling . I found that the flour was thrown away from the edge , but it was n’t collected , leaving a sight behind . It seems as though on this pass , the robot could n’t quite put to work out how to run down the edge of the kitchen cupboards .
reprize the business with the vac and mop turned on , the upshot were brilliant , with the automaton using its extendable swob pads and arm to get all of the crap .
Cleaning almost to the sharpness , the Dreame L40 Ultra only pass on behind a trace amount of flour .
I put the Dreame L40 Ultra into swab - only modality for my mow test . The initial test was for dry - on coffee discoloration , which the Dreame L40 Ultra handled brilliantly .
likewise , it manage to strip up the red wine stains on its first strait .
Then came the guileful ketchup test , which was handled with ease by the automaton in just two pass . The detergent and live pee washing come into great consequence for this sturdy test , as was the camera , which can spot spot and help the robot contend with them .
My mud test rise a bit tricky . While the stain was greatly reduced , there was still an precis of mud left on the floor after two offer . I had to send the Dreame L40 Ultra out again for another two passes to transfer this earth - in mess hall .
prove with human hairsbreadth , I found that the Dreame L40 Ultra collected it all without nonplus any tangle around its brush . Some strand of haircloth were loose around the brush bar , but they got sucked up after next runs .
Battery sprightliness is range at up to 194 proceedings , although this is running the vacancy on its lowest index setting . Once again , I ’d say that even on high power options and multiple passes , battery life is not an issue . There ’s enough succus in a charge to tackle the entire trust Reviews Home Tech Lab , and have enough might left for various spot jobs .
I measure the Dreame L40 Ultra at 71.3dB , which makes it one of the gaudy golem that I ’ve try ; however , that ’s worth it for the cleaning performance on fling .
sailing is first-class , using a combination of LiDAR and the photographic camera on the front , I found that the Dreame L40 Ultra get close to furniture , but avoided common obstacle , including cables , shoe and ( fake ) pet mess hall . obstacle are marked on the single-valued function , so I could go and move them for future cleans .
