Have this. Bought last year, after trying out 3 or 4 others, and paid close to $1200. Although it will take years of reliable service to make it worthwhile, it has been a reliable partner so far in light duty daily cleaning tasks

$500 is a fantastic price and a great value.

It does good work vacuuming hard surfaces.

Navigation is perfect and the app lets you subdivide rooms, customize the kind of cleaning to be done and set up scheduling easily.

The self cleaning functions for the mop pads are excellent.

The base unit is all plastic but it feels like it's put together well and it's thoughtfully engineered.

It isn't bad at maintenance mopping dust, food residue and footprints off of tile and solid surface flooring.

It's not great with long dog hair on normal rugs and carpets.

It's not going to clean up a glass of spilt milk.

NONE of these bots are maintenance free. It still requires periodic attention such as water changes for the mops, bag changes for the base and, if you have long hair animals, occasional unclogging and weekly cleaning of the brushroll.

ANYONE looking at ANY of these cleaning drones to replace an upright vacuum on thick rugs or standard or plush carpet will be disappointed. They just don't have the heft or the agitation needed to do it well. Stick with an upright for those areas.

They also aren't able to mop like a dedicated upright power mop or a regular mop and bucket. The pads are small and because of that they carry limited cleaning solution and hold limited debris. Good for maintenance runs though.

Again, this particular unit for $500, knowing what I know now, is any easy buy. Too good to pass up if you keep your expectations realistic and can live with the constraints I mentioned.

Community Reviews

The X40 Ultra is a capable robot vacuum and mop for hard floors, with strong navigation, precise room mapping, and useful app controls for scheduling and custom cleaning. It self-empties, self-fills, and hot-air dries the mop pads, while also avoiding stairs and other drops and skipping carpets when mopping. It handles everyday maintenance well on tile, textured concrete, and short shag, but thick rugs, long dog hair, and upright-level deep cleaning remain weak spots. Some units also struggle with dock ramps or fail early, so it is best suited to homes that match its lighter-duty strengths.

Common Questions (5)

  • It can handle about 1/2- to 3/4-inch transitions and climb onto many rugs, including in a great room. It also detects carpets and skips mopping them automatically, but thick rugs and plush carpet are still a weak spot for this class of robot vacuum.

  • The L40 Ultra is newer and cheaper, and several comments point to it as the better buy. The X40 Ultra is still a strong option if you want the older model at a lower price, but the L40 is repeatedly described as the better value.

    capon3capon3WiseBike968imnobody

  • Yes. It can detect stairs and other drop-offs on its own, and you can also set a virtual wall to keep it away from specific drop areas. That makes it usable around sunken rooms or stair edges without needing to physically block the space.

  • It does very well on hard surfaces, tile, textured concrete, and short shag carpet, with strong navigation and good app controls. It is not a replacement for an upright vacuum on thick rugs or standard plush carpet, and long dog hair can be a problem.

    thebigblue92TheCarsForeverfangsz

  • Yes. The base self-fills and self-empties, and it uses hot air to dry the mop pads. The mop self-cleaning function is also described as excellent, which reduces but does not eliminate maintenance.

In market for one, but we have a sunken family room. Any suggestions? Someone on Amazon replied to my review to build a ramp. Wouldn't that defeat purpose of sunken room? Don't need this to climb down to family room but at least would this detect the drop and not fall in?
I have this model and find it does an exceptional job of avoiding stairs and other 'drops' without doing anything. You can also mark off an area with a virtual wall so it won't even try to go over a drop area. I have been really happy with it on hard floors, textured concrete (looks like tiling) and very short shag carpet. We have it run every night in the early AM through the main part of our house and it has been doing a great job.

Im trying to buy a robot vacuum in the $500 range. Are these the best out there right now? L40s ultra or X40 ultra? Also would these work with Home Assistant?

The L40 is the X40 but newer and cheaper and according to reviews better. Also works with smart devices.

One of the best vacuums I've used till date after my Dyson V10. Have been using this since July this year it Works like charm and avoids getting stuck. Has mapped my house pretty welll over the last 6mths and precisely gets to a spot I want cleaned. Would highly recommend. Bought this refurbished on eBay for $419, they pretty much sent a sealed box felt like new

they need to make one where it auto detects carpets / hard wood floor without removing the pads.

Better to get it from Costco, I believe it's equivalent to the Dreame X40 Ultra.

Bought this a month back and it's great at navigation and detecting steps.

Also detects carpets and skips mopping them. Lot of cleaning customization options like , vacuum speed, vac first vac and mop, fee cleaning


Also tells if it detected dirty floor and recommends cleaning again

The Dreame website is the same price with 10% off via GovX for Military, First Responders, Teachers and Medical professionals. Also a cash back site gives back 4% (my enunciation rhymes with "back you 10.")
