Dreame - S30 PRO Ultra

It depends on tall your thresholds are: For single thresholds: Up to 2cm: most modern robots can cross with no difficulty Up to 2.2cm: Dreame L/X40 Ultra. The dreame models with the EasyLeap wheels (L40S Ultra/Pro Ultra and the L50 Ultra) can cross the first threshold up to 2.2cm and a secondary threshold right after up to 1.8cm Up to 3cm: roborock models with the AdaptLift chassis. It can cross a single threshold up to 3cm and a secondary threshold right after up to 1cm. Up to 3.5cm: the MOVA P60 Pro Ultra (mainland china only for now) has active suspension like the roborock Adaptlift chassis and the EasyLeap edge climbing wheels to climb a single threshold up to 3.5cm and a secondary threshold up to 3.5cm. Up to 4.2cm: Dreame X50 Ultra, Dreame Aqua 10 Pro Track, and the MOVA V50 Ultra all can cross a single threshold up to 4.2cm if the threshold is shorter than 9-10cm (5.2cm if the threshold is sufficiently long enough) and a secondary threshold up to 1.8cm.

Thanks for sharing! I hypothesize that the X50 Ultra's poor battery life is likely due to the more power-hungry computer chip it utilizes. My own experience with the L40s Pro Ultra (mainland Chinese version) had a *worse battery life* that struggled to finish cleaning my home whereas my much cheaper combo Xiaomi robot (also mainland Chinese version) that has the same battery capacity and is also made by Dreame would be able to vacuum first and then mop my small apartment and finish with 50%. Other reviewers have reported that the L40s Pro Ultra (non-mainland Chinese edition) had a bad battery life, just like me :( Hopefully, this issue will be fixed soon. I hope the Dreame Aqua 10 Pro Track doesn't suffer the same battery life issue, especially because it'll need a more powerful chip to process all the information coming from the HD binocular RGB cameras and the dot projector, and a power-efficient water heater in the robot to heat the water up.

1. It really depends on your purchasing region. Costco is a popular choice given its generous return policy but choices are rather limited compared to buying from Amazon which has an easy return policy within 30 days. For other purchasing regions, buying from a reputable retailer with a good return policy and an optional protection plan would be good. In Australia, I heard Harvey Norman is nicer with returns compared to JB HIFI. 2. The robots with the best self cleaning will be Dreame’s L/X50 Ultra/L40S Ultra/Pro Ultra and MOVA’s V50 Ultra P50S Ultra > MOVA’s P50 Ultra/ Pro Ultra > Roborock’s models that have spinning mops with the Multifunctional Dock 3.0 (roborock models with a vibrating mop have a washboard that is more difficult to clean as you can’t remove it) ≈ Narwal Freo models (completely detachable base) > Dreame’s models with the mop-driven wiper mop washboard (cleaning the wiper washboard is rather difficult since there’s too many nooks and crannies and you’d still have to get down to clean the areas the wipers can’t reach) > other combo robots with an all in one base station As for combo robots with roller mops and have an all in one base station, the washboard is generally flat with a few grooves so it’s pretty easy to clean. I believe most of their washboards are removable. However, it’ll require more cleaning in the mop compartment and dirty water tank. Most roller mop models have an annoying cylindrical component which drives the roller mop like an upright wet dry vacuum but you can’t remove or move it to give it a deeper clean even if gunk is stuck on it. The only combos that are close to the level of self cleaning for spinning mop models are Dreame’s Aqua 10 Pro track, the MOVA Z50 Ultra, and the Narwal Flow since both have self-cleaning mechanisms that are made to also clean the dirty water tank and the mop compartment while also having a very easy to clean mop compartment since the thing that moves the mops is also completely removable. If you want to support a US startup, you could look at the Matic since it’s a vacuum and mop robot but taking care of it looks rather easy since it lacks a base station. The maintenance involved is replacing the bag, refilling the water with a cleaning solution of choice, occasionally cleaning the roller mop, the roller mop filter, cleaning the brush roller and de clogging the mop tubes if needed.

I have this one as well, but the version without the self emptying deck. I'm always scared of bugs climbing in there and nesting before I get to empty it. This being said, I love it, and it's not even my first Dreame: I've never been able to find a better quality/price deal.

Just get the top level dreamebot or roborock (same company owns both). Their robots do an excellent job, and the app works really well!

Looks like you’re right, they are technically not both currently owned by xiaomi, but they share a ton of similarities. My coworker has a dreamebot and his app, replacement parts, features are nearly identical to my roborocks.

The Dreame robot mop system is our favorite new roommate! We have a new and an older iRobot Roomba vacuums and recently got this one for the main floor. We're very happy with it. It's available in many different price ranges.
