Dreame L40 Ultra

The L40 Ultra is built around covering more ground with less intervention: four saved maps handle a multi-floor house without remapping each time, and the auto-empty cycle stretches to 75 days, long enough that a big home's extra debris volume doesn't mean constant dock trips. Suction at 11,000Pa is tuned for the wider mix of hard floors and carpet a larger house typically has room by room.

The dock's washboard-and-hot-water mop cleaning is more thorough than a simple rinse, which matters over the larger mopping runs a big floor plan demands, and auto-refill of both water and cleaning solution keeps the whole cycle hands-off. It's a heavier, larger robot and dock than most in this guide, which fits the larger homes it's built for but is worth planning space around. It suits a multi-floor house that wants long stretches between manual dock maintenance.
