    Worth Every Penny

    I've had other less expensive robot vacuums but this Dreame model is worth the price tag. Vacuum and mop features do a great job. I love the ability to customize jobs and the cleaning intensity.

    First impressions

    My first impressions of this robot vacuum/mop is very good. I put the tri-cut brush in right away because of our German Shepherd who sheds daily! Thus far, I am very pleased with the thoroughness and effectiveness that this works.

    I've been a loyal user of iRobot for years, but this DREAME L40s was ranked really well and had great reviews, so I gave it a shot. So happy!! We have a new puppy who is potty training...so the hardwoods stay a mess with him going in and out with all the rain. The unit is MUCH quieter than anything I've owned in the past. I've never been able to have one active with my hubby on the phone (he works from home) but he says he can't hear it unless it is right under his feet! It has the mapping function, so once it maps the house (or floor really because they get confused if you move them from floor to floor - you need one for each floor of the house), you "define" the rooms and then you can tell it where to clean or just let it do the whole thing. I ran it for the entire basement (about 1,500 sq ft) of hardwoods and area rugs with one room carpeted - it took about 5 hours and then told me it needed to do the whole thing again because of the high grime level (yikes!). It looked great to me :D I have mine set to vacuum and mop, but it recognizes when it is on the carpet/area rug and doesn't mop those. The charge seemed to last for the whole clean, but it did have to go back and wash the mops and refill the water several times (so I guess it charged a bit when it did that). Once it was done, it dries the mop heads (super quiet fan - we watch tv in the same room while that is happening!). I've run it multiple times now - selecting only the rooms I want cleaned and I just LOVE IT! It is pretty big, but I have it in a corner. Great deal and super easy to use with the app! I never watched Grey's Anatomy...but this is definitely my McDreamy!!

    Excellent cleaning

    I don't know why it took me so long to buy a robot to scrub and vacuum our floors. This is an amazing machine that I find fascinating to watch ensuring that it does a good job cleaning the carpets, vinyl luxury flooring and throw rugs; seemingly performing its job. When it needs to clean the mop heads or empty the bag; the robot goes back to the base, cleans its self and then resumes cleaning where it left off!
