    About

    The Dreame L40 Ultra is part of the Vacuum Cleaners test program at Consumer Reports. In our lab tests, Robotic Vacuum and Mop models like the L40 Ultra are rated on multiple criteria, such as those listed below.

    Carpet: A high score means the vacuum effectively removes surface debris and embedded dust from medium-pile carpet. A top-scoring model picks up more debris from carpet per run.

    Bare floors: A high score means the vacuum effectively removes surface debris like sand from smooth hard floors. A top-scoring model picks up more debris from non-carpeted flooring per run.

    Mopping: A high score means the mop effectively removes dried liquid stains. A top-scoring model removes most or all of the stain.
