Dreame - L40S Ultra

"The dreame L40S Pro Ultra has much better obstacle avoidance and object detection for smarter cleaning features like stain detection and large particle detection where it’ll slowly mop only or slowly vacuum only and not use the side brush so it won’t be kicked away."

"My LDS-only Xiaomi would always get tricked by a floor to ceiling mirror and think there’s a magical place beyond it due to the limitations of LDS. ... My Dreame L40S Pro Ultra (same 110° LDS sensor but with an RGB camera and fill light) was able to accurately tell that the mirror was actually a mirror wall and after cleaning that room, correctly identify it as a wall (the LDS and the RGB camera would fight while it’s cleaning the room over whether or not it’s a wall or a magical portal but it wised up when it finished cleaning that room)."

"no issues long term with map and getting lost"

"The AceClean dryboard (its mop pad cleaning tray) on these models is currently the best self cleaning mop tray that can clean its mops as the only maintenance required is to occasionally clean a removable palm-sized drainage filter and wipe down the flat dryboard (no nooks and crannies for dirt to hide)."

"Dreame’s L40S Pro Ultra will have the best self cleaning as it cleans the filter (your filter won’t be as clogged with dust as easy) and the mop pad cleaning tray the best."

"It'll have the best self-cleaning ability at the best price due to the AceClean dryboard, which cleans itself much better than the Dreame X/L40 Ultra and the self-cleaning filter in the dustbin (works best if you set it to vacuum first before mopping, as mud won't be in the filter)."

"the new dreame robots (L40S ultra, L40S pro Ultra, and the X50 Ultra) in Australia cleans its own filter when it autoempties."

"and is really low maintenance (the autoemptying cleans the filter and the mop washboard is the lowest maintenance so far)."

"the same models can also compress the fur in the dustbin as it vacuums. ... the models with the fur compression feature will be able to push any fur to the end of the dustbin and will not be as easily clogged with empty spaces."

"This model will be best for homes with heavy shedders as it will compress the fur in the dustbin as it vacuums to best utilize the space."

"The dual anti-tangle main brushes work great for pet hair and the same models can also compress the fur in the dustbin as it vacuums. ... I have a heavily shedding corgi and the old robot wouldn’t be able to handle his fur as it’ll be clogged with a lot of empty space on the sides of the dustbin to the point that running it twice a day would mean he wouldn’t shed enough for this to happen. ... However, the models with the fur compression feature will be able to push any fur to the end of the dustbin and will not be as easily clogged with empty spaces."
