It also handles pet (and human) hair extremely well.
It’s not cheap, but it is very keenly priced for what you’re getting.
In fact, it’s one of thebest robot vacuumsI’ve tested.
In fact, it tops our guide to thebest robot vacuums for pet hair.
It mops exceptionally well, too.
And that means you’ll spend less time doing maintenance.
you’ve got the option to buy direct fromDreame, or head to a third party retailer likeAmazon.
Moving on to the robovac itself.
And so it leaves them behind in the dock, just in case.
Its initial mapping run was not only fast but exceptionally accurate, too.
you might read more about my obstacle testing in the Performance chapter below.
Top marks in this regard.
For some reason, most robot manufacturers still insist on producing circular bots instead D- or square-shaped models.
Nevertheless, I haven’t seen any significant reduction in dust collection as a result of having just one.
It’s worth fitting this replacement roller if you have cats or dogs of the shedding variety.
Robot vacs of this nature are usually really easy to set up and this one is no different.
But how well does the L40 Ultra actually clean?
What’s more, this bin-emptying sequence isn’t too loud either.
I’ve been especially impressed with how well the L40 Ultra has tackled our large village hall.
That’s a remarkable statistic.
I put that down to those spinning mops and the downward pressure exerted on them.
And that means I wouldn’t want to trust it with dog mess of any variety.
Other than that common anomaly, I give this bot full marks for performance.
That’s what I love about the Roborock app.

The L40 Ultra’s dock is massive and ugly.
You’ll need space to store it, and possibly somewhere it’s not too on-show.
Thankfully there are none to report.
I also took into consideration its overall performance and whether or not it fitted comfortably within a home environment.
