A capable mopper with a full dock for about $500 to $570, but a step back from the original L40 Ultra in obstacle avoidance. Vacuum Wars saw it avoid only 2 of 24 objects and wrap 67% of long hair. Pick it only for tidy homes without long hair; Vacuum Wars itself points pet owners to the L40s Ultra.
