Ecovacs Deebot Ozmo U2 – the value robovac/mop (review) – GadgetGuy


Worth providing

The Ecovacs Deebot Ozmo U2 is its worth providing. As such, now we have needed to invent a complete new check paradigm. What do you anticipate from a $399 product in comparison with one that’s three-or-more instances the worth?

To be blunt, if we in contrast Deebot Ozmo U2 to its good Deebot siblings, it is a dumbot! Why? It doesn’t have issues like LiDAR good mapping, clever impediment avoidance, good mopping and all that goes with that. In case you anticipate extra (and as a reviewer, maybe I’ve been spoiled in that regard), know that it’s a restricted gadget that it’s best to solely purchase if you realize what it’s best at.

Notice this isn’t the U2 Professional Mannequin DDGN22-72 or 74. These are primarily the identical robotic with completely different pet care kits – mud bins and a rubber tangle-free brush.

Take a look at house

We now have finished vacuum opinions for a few years and use a three-bedroom house because the check mattress. It contains about 30% lengthy and dense shag pile carpet (that few robovacs have conquered), 30% bamboo hardwood flooring, 30% sisal ribbed carpet and 10% ceramic tiled bogs

It has a Netgear AX router. Sign power is great. The two.4Ghz band on the level furthest from the router is approx. -55dBM and 150Mbps (good).

All opinions have a minimal of 4 runs – this had 11 as we tried to enhance our findings.

Let’s kind out the element on robovacs

Robovacs are available two primary flavours.

The dearer ones use LiDAR or just like create a 2D map of the vacuum space. They’ll set go-and-no-go zones which can be important if the gadget has a mopping pad. Some are higher than others at impediment detection. The nirvana is to have the ability to go away the robovac to its job with out lifting all the pieces off the ground beforehand. Primary designs are spherical and D-shaped – we get higher outcomes from the latter.

We check in opposition to greater than 40 paradigms. Examples of spherical are the Deebot OZMO T8 AIVI 8.2/10. The D-Formed is the Neato D7 9.2/10.

The lower-cost ones just like the Deebot OZMO U2 are, for need of a greater phrase, unintelligent robovac/mops. These connect with Wi-Fi on the base station, and navigation is through a set U-or-V-shaped cleansing sample. It backs out of the bottom station and begins cleansing or mopping. From there, it bumps round the home till it runs low on battery and tries to search out the dock.

The mopping plate seems unremovable.

Notice that it doesn’t have an auto-resume after charging.

Google Voice

The Ecovacs app can connect with voice assistants. It may begin/cease/pause or return to base. As this doesn’t generate a map, you can’t direct it to scrub particular rooms or areas.

The app will enable scheduled cleansing.


To be clear, it doesn’t map the house. You may set no-go zones utilizing 3-metre magnetic flooring strips – they value about $50.

magnetic tape

With out good mapping, it didn’t discover all rooms and missed some open plan areas.

Vacuum energy

It has a 26W (Max+) suction energy. We aren’t certain what that is in conventional Kilopascal (Pa) measurement, however it’s on the decrease finish of the size. Higher robovacs may have over 50W energy.

Cleansing velocity

It averages about .8m2 per minute (48m2 per hour). That’s sluggish in comparison with the Neato at 90m2 per hour. It’s sooner on Max+ suction however on the expense of battery life.

The rationale, nevertheless, it easy. The comb is about 14.5cm broad in comparison with 27.5cm of the Neato. Ergo it takes twice as lengthy to cowl the identical space.

Cleansing effectivity.

This makes use of U-or-V-shaped cleansing patterns – no map. Over 11 runs, it typically cleaned about 70% of the house lacking complete rooms and stubbornly lacking a sizeable space subsequent to its dock.

Any ’spherical’ robovac misses edges, particularly beneath built-ion overhangs. That is no completely different. We set it to edge mode, however all it did was bump alongside the sides till it bought caught.

The dustbin is approx. 400ml – not giant, and it was full on the finish of a 50-60m2 run (no, we don’t have a unclean house).

Deebot Ozmo U2
The 400ml dustbin fills in a short time. The filter additionally clogs simply.

After every run, we ran the Neato D7, a completely clever robovac, over the identical space, and it discovered a few additional 700ml of detritus.

Deebot U2 high. Neato D7 backside. Notice the Neato is over twice the amount and picks up bigger particles.

Our checks embrace hair and particles starting from small crumbs to rice bubbles. It was OK on hair, however the bigger particle pick-up was very hit or miss. It was significantly inefficient on sisal (ribbed wave sample) wool carpet, lacking nearly all detritus.

On later checks, we set the vacuum suction to Max+ to scrub the quick pile sisal wool carpet. But, it nonetheless left some detritus within the ‘valleys’. This additionally considerably shortened battery life – we estimate that it will be nearer to 50-60 minutes on quick pile carpet.

Extra highly effective robovacs deal with this with ease leaving no detritus

Door sill negotiation

The 60mm knurled wheels deal with 20mm sills. However something over that ends in it getting caught or spinning its wheels, particularly with the mop plate hooked up.

However the worse factor is that it typically dumps appreciable detritus from the comb because it climbs over the sill.

At each sill we discovered ‘brush’ dumps


It’s fairly typical at 68dB in default mode to 78dB in Max+ mode.


It makes use of a 240V to 19V/.6A/11.4W wall charger to a 14.4V/35.56Wh battery. The battery makes use of 4 1865o (or related) lithium-ion 3.7V, 2600mAh, batteries in sequence. Which means the batteries use one recharge cycle when exhausted and half thereof when topped up (good). The batteries have about 200 recharge cycles. Assuming you utilize it as soon as every week, it ought to final 3-4 years.

Generic replacements (not authentic) are about $60, or you might get them repacked domestically for lots much less.

Ecovacs declare battery life at 150 minutes on a tough flooring with commonplace suction. Within the specs, it claims 110 minutes. We couldn’t measure the remaining battery as there isn’t a app info.

Our first try with vacuum solely noticed 78m2 and 65 minutes on a 30/70% mixture of sisal wool carpet and exhausting timber or ceramic tiled flooring. Recharge time was about 3.5 hours, so it was not fully empty. Later runs drained the battery in 85 minutes. Recharge time was over 5 hours.

Max+ mode will successfully half run-time.


You connect the passive mop plate to the reservoir – it seems unremovable. A micro-fibre mop fabric attaches to the Velcro plate. There are additionally one-use paper wipes.

That is the mop after 15m2 – you should take away the pad and wash it earlier than persevering with

Advertising and marketing claims it has an digital water pump. No, it’s gravity-fed from a 300ml reservoir by way of 4 holes. To extend the water from the usual to greater move means it slows the robovac flooring velocity down.

Deebot Ozmo U2
No electronics right here!

The mop is ‘patchy’ at greatest. It leaves streaks of water, and the random sample means it takes a very long time to mop an space.

The reservoir was empty at about 40m2. We discovered that until you wash the mop fabric at 15-20m2 intervals, all it does is drag soiled water over the ground. That is just like most passive mopping methods.

Error dealing with

None- if it will get caught, it’ll let you know after which cease till you progress it. When you do that, it appears to lose any spatial consciousness. We surmise that’s the reason it was unable to return to the bottom station – it returned to the final error place.


There’s a Deebot official eBay retailer right here the place you will discover costs. Replacements are pretty commonplace costs.

Construct high quality

General, it’s properly made. The mud entice within the dustbin is a chunk of sunshine plastic and will put on. The comb meeting doesn’t float, so a floating bar tries to maintain flooring contact, and it may put on.

It’s approx. 337mm spherical, and 79mm excessive and a couple of.75kg.


Whereas a robovac ought to have a low privateness threat, we propose fastidiously studying the Privateness Coverage and Phrases and Circumstances that you should comply with earlier than utilizing any product.

All gather some private info while you signal as much as allow the corporate to focus on its personal and third-party promoting to homeowners.

Points to pay attention to

  • It loses Wi-Fi contact so much. As soon as misplaced, it can’t return to base. Lack of Wi-Fi doesn’t have an effect on cleansing – it’ll go till the battery is empty.
  • It makes use of a gravity-fed passive mop plate meaning it is advisable to watch out with water porous surfaces.

GadgetGuy’s take Deebot Ozmo U2

It’s a lower-cost, unintelligent robotic vacuum cleaner and mop. It may carry out a light-weight clear and mop utilizing a U-shape cleansing routine extra suited to open plan.

So long as individuals don’t purchase it with the expectation of something extra, it’s match for function, and now we have finished our job.

However we strongly recommend that patrons take a look at these fashions which have clever mapping – I may by no means return!

Once we evaluate tech, we additionally take a look at the advertising and marketing claims and evaluate them to our findings. Our take is that whereas we perceive the need to current any gadget in its greatest gentle and anticipate a sure diploma of hyperbole, it should be correct.

Score – DeebotOzmo U2

Sensible Robotic opinions gave it 57 factors in comparison with the Deebot T8AIVI (one of many high 5) at 191.

You can not evaluate it to any clever robovac. In case you evaluate it to any unintelligent robovac/mop, it’s match for function.

Advertising and marketing claims and specs are sometimes at odds

All specs are from its specs web site or measured by us. The advertising and marketing claims are from its Options web site (in italics) and don’t all the time agree.

We’re going to name the extra apparent ones out.

  • DEEBOT Ozmo U2 is right here to give you maximized cleansing efficiency. It’s a pretty light-weight robovac by way of suction energy and mopping efficiency and in no way environment friendly in masking a house as an clever robovac.
  • DEEBOT Ozmo U2 can clear a whole house* at a time (*As soon as totally charged and crammed with water, DEEBOT can vacuum and mop a flooring space of as much as 200 sqm). The 300ml water reservoir on commonplace mode (not excessive quantity) is sweet for approx 50m2. Relying on detritus, the mud bin will fill after about 50m2.
  • Max+ Mode (2.5x energy enhance) allows elevated suction energy to deal with essentially the most demanding duties. Max+ mode is critical for longer pile carpets and reduces battery life and washable space by over 50%. It’s nonetheless not highly effective sufficient for demanding duties.
  • For a deep clear of your whole house. No, it’s a really gentle clear, selecting up about 50% of what dearer robovacs do
  • An electronically managed water pump persistently attracts water from a big reservoir to provoke mopping. No,it’s gravity fed and will increase water quantity by slowing down the robomop – no electronics in any respect.
  • The exhausting flooring mode, optimized for exhausting flooring cleansing, ensures that DEEBOT U2 can observe a complicated, back-and-forth cleansing sample for a extra thorough and systematic clear. Whereas it begins in exhausting flooring mode, it shortly reverts to V-shaped. We suspect that is to do with Wi-Fi dropout.


  • Use the best instrument for the job with a set of focused cleansing mode choices: Auto mode for normal cleansing, Edge mode for cleansing particular edges, and Spot cleansing for when intensive cleansing in a single space is required. As there isn’t a intelligence, edge-mode contains bumping its means across the ‘edges’ and infrequently getting misplaced.
  • No human intervention required! When battery energy will get low, DEEBOT mechanically returns to its Dock Station, all by itself. Not as soon as 11 cleans did it return to base. We suspect that this is because of Wi-Fi dropout – not on account of our immensely highly effective and blackspot-free checks house.
  • DEEBOT strikes safely round your private home utilizing anti-drop sensors to scrub round stairs. It solely dived as soon as over the ‘stairs of demise’. The robotic was new, so the sensors ought to have been clear. We cleaned the sensors, and it continued to push the stair boundaries because it doesn’t have a mapping system
  • With its anti-collision sensors and comfortable cushion bumpers, DEEBOT can keep away from obstacles and shield your furnishings. This sounds nice, however the information are that it bumps fairly solidly into furnishings, and we can’t determine any anti-collision sensors other than the bumper.
  • Precise efficiency might fluctuate. Maybe essentially the most correct advertising and marketing assertion.
It went over as soon as however after cleansing the sensors it saved pushing the boundaries.

If Deebot needs to reveal in any other case, I will probably be blissful to eat crow. Essentially the most precious lesson for all distributors is to be correct in claims. This performs in addition to anticipated from a dumbot!

Pretend opinions

Fakespot states that opinions from Dwelling Depot verified clients are seemingly faux. Its evaluation – a excessive recurrence of phrases and phrases as if from the identical songbook.

Most have a variation of this phrase, “I all the time dreamed for one, however I couldn’t afford it till now when Ecovacs determined to make of [sic] for all pockets.”

Fakespot additionally known as out Amazon opinions that had been extremely inaccurate. Amazon tends to combination opinions for all fashions. A evaluate for an clever robovac shouldn’t seem within the U2 opinions.

It it match for function as an entry-level ‘unsmart’ robovac and mop.
