A cheap way into a self emptying, mop washing dock with long runtime. Vacuum Wars found good carpet cleaning and no hair tangles, but weak pet hair pickup, poor obstacle avoidance and wet mopping. Spend more on the L40s Ultra or AE if you have pets or clutter.

A mop first robot with firm pressure and hot air drying, now far below its launch price. nextpit measured 96% sand pickup on carpet, but Vacuum Wars scored its obstacle avoidance poorly. There is no dock emptying, so you change a small bag in the robot.
