What the dock does, and why it matters more than the robot

A robot vacuum on its own is a small battery-powered fan with brushes and a few sensors. Put a mop on it and give it a dock that washes, dries and empties, and you've built a little plumbing system on your floor: a clean-water tank, a dirty-water tank, a pump, some valves, a heater, a fan and a dust bag. That's where all the convenience comes from, and in my experience it's also where most of the faults come from now.

Every pick here empties its own dustbin into the dock and washes its mops there, and most of them dry the mops afterwards too. The differences are in how hot the wash water gets, whether the mop is a pair of spinning pads or a roller, how high the robot can climb, and how low it can get under the couch. Those four things decide whether you'll still be using it in a year, far more than the suction figure printed on the box.

If you already own a plain robot vacuum and you're happy with it, read my general robot vacuum guide before spending this sort of money. A mop dock makes the most sense in a house with lots of tiles, timber or vinyl, a dog or kids tracking dirt in, and someone who won't mind tipping out a dirty-water tank a couple of times a week. On wall-to-wall carpet it's mostly money spent on a feature you'll barely use.

Roller mop or spinning pads

There are two ways these robots mop. Roborock and Dreame use a pair of round pads that spin against the floor, and the ECOVACS T90 Omni uses a single roller that runs across the width of the robot. A spinning pad presses down hard and scrubs well on a dried coffee drip. The roller gets rinsed with fresh water as it turns, and ECOVACS says that means dirty water isn't reused across your floor, which is a fair point on a long run through a kitchen.

Downward pressure is the number to compare if you've got sticky floors. Roborock lists 8 N for the Qrevo Edge 2 and up to 14 N on the Edge 3 Pro, with the pads spinning at 200 RPM on the Pro. ECOVACS doesn't give a newton figure for the T90's roller, it just says strong downward pressure, and Dreame doesn't list pressure on either of its picks. I'd treat the missing numbers as unknown rather than bad, but it does make the Roborock pair easier to judge on paper.

Edges are the other difference. Spinning pads leave a strip along the skirting, so every pick here swings something outwards to reach it. Roborock's FlexiArm pushes the side brush out to clean toe-kicks down to about 25 mm, Dreame's arms extend the side brush and a mop, and the T90 slides its roller 1.5 cm sideways with a felt strip on the end that rides along the wall. Moving arms are extra hinges and small motors near the floor, so I'll come back to them in the fault section.

Hot water washing and drying

The dock's wash temperature is the spec that's moved most in the last couple of years. The Dreame L50 Ultra AE and the Roborock Qrevo Edge 3 Pro both wash their mops with 100°C water, the Qrevo Edge 2 uses 80°C, and the T90 Omni's title says 75°C. The X50 Ultra listing doesn't state a wash temperature at all. Hot water shifts cooking grease from a kitchen floor much better than cold, and it usually stops the pads going sour as quickly between runs.

Drying matters just as much. A wet microfibre pad left in a closed dock for two days will smell, and it'll leave that smell on your floor next time it runs. The two Roborocks dry their mops with 55°C air after washing. The Dreame L50 lists drying without a temperature, and the other listings mention washing or self-cleaning but don't mention drying, so check the manual on the day you buy. If you live somewhere humid, like most of the coast here in summer, warm-air drying is worth paying for.

Heating water to 100°C takes power, and that heater sits next to a pump, valves and a pool of dirty water. That's not a reason to avoid hot-wash docks, it's a reason to keep the dirty tank emptied and the base tray wiped. When a dock's heater or pump circuit fails, it's usually because water has found its way onto a board or a connector, which is the same slow corrosion I describe in how water damage spreads through electronics.

Thresholds, rugs and low furniture

Australian houses throw a few specific obstacles at these robots: sliding door tracks, tile-to-timber trims, thick bathroom mats and couches with a gap of about 9 cm underneath. A robot that gets stuck on a door track twice a week is one you'll stop using pretty quickly. The Qrevo Edge 3 Pro lists the best climbing here, with 45 mm single thresholds and up to 88 mm for two-step thresholds. The X50 Ultra lifts itself on retractable legs to clear 6 cm.

Height under furniture is the other half of it. The Qrevo Edge 2 is 80 mm tall because its laser turret drops down when a sensor sees a low ceiling above it. The Edge 3 Pro lists about 80 mm of clearance access, the X50 Ultra lowers itself to 89 mm, and the T90 Omni is 95 mm tall. Measure the gap under your couch and bed base before you buy, because 15 mm is often the difference between cleaning under there and bumping off the front edge all day.

Rugs and carpet need the mop out of the way. The Edge 3 Pro can leave its mops in the dock and go back out for carpet up to 46 mm thick, the X50 Ultra offers five carpet modes that remove or lift its mops, and the T90 Omni lists a Triple Lift System for keeping wet and dry jobs apart. If you've got a big shaggy rug, I'd still set a no-mop zone in the app rather than trusting a sensor to spot it every single time.

Why I don't pick on suction numbers

The listings quote 20,000 Pa, 24,000 Pa, 30,000 Pa and 36,000 Pa as if more is always better. Those are peak pressure figures measured at the fan in ideal conditions, and they don't tell you how well the brush lifts hair out of carpet or how long the robot holds that figure before the battery sags. In my experience a clean filter and a brush that isn't wrapped in hair matter more on a real floor than the last 10,000 Pa on the box.

Where suction does show up is on carpet and pet hair. If you've got a long-haired dog and carpet in the bedrooms, the higher numbers on the Edge 3 Pro and T90 Omni are a reasonable tiebreaker between two otherwise similar robots. On mostly hard floors, the X50 Ultra's 20,000 Pa is plenty, and I'd choose on climbing, height and mop washing instead. Grit and crumbs on tiles come up easily with any of these five, so don't pay extra for suction you won't notice.

Hair on the brush is the bigger day-to-day issue. Every pick claims some kind of anti-tangle brush. Dreame's L50 has a blade built into the brush that cuts hair as it goes, the X50 Ultra's DuoBrush is rated for hair up to 30 cm, and Roborock and ECOVACS use shaped brushes and airflow to stop hair wrapping. None of them are perfect in my experience, so expect to pull the brush and cut it clean every few weeks if there's long hair in the house.

Wi-Fi, apps and the 2.4 GHz catch

Both Roborock listings say plainly that they only support 2.4 GHz Wi-Fi. That's normal for appliances, but it catches people out when their router broadcasts one combined network name and the phone setup keeps trying to join on 5 GHz. If setup fails, split the bands for a few minutes or make a separate 2.4 GHz network just for appliances, which is what I'd do anyway in a house full of smart plugs and cameras.

Signal strength matters more than people expect, because the robot spends half its time under beds and behind couches. If the far bedroom drops out on your phone, it'll drop out on the robot too, and you'll get half-finished maps and missed schedules. A decent router or a mesh Wi-Fi system that covers the whole house usually fixes more robot complaints than any setting buried in the app.

The apps are where the brands differ most. Roborock lists SmartPlan 3.0, Apple Watch control and a Pet Care Hub, ECOVACS has its YIKO assistant, and Dreame's listings say very little about software. All of them need an account and a cloud connection for full features, so I'd check the app's reviews on your phone before buying and accept that the robot's useful life partly depends on the company keeping that app updated for years.

Running cost: power, water and consumables

The power used for vacuuming is small. The bigger draw is the dock heating water and blowing warm air through the mops, and none of these listings state the dock's heater wattage. As a worked example, if a dock pulls 1,000 W for ten minutes after each run, that's about 0.17 kWh, or roughly 5.5c at the AU average tariff of about 33c/kWh. Run it daily and that's about $20 a year, so power isn't a reason to choose one over another.

Consumables are where the real running cost sits. Each dock uses a dust bag, the robots use a filter, side brushes and mop pads or a roller, and most docks take a branded detergent. ECOVACS says the T90's dock holds up to 90 days of dust, Roborock lists up to 65 days on both its picks, and the Dreame listings don't give a bag life. Price a year of bags, filters and pads on the day you buy, because it adds up over the life of the robot.

Use the detergent the maker specifies, or plain water. Supermarket floor cleaners can foam in the dock, leave residue in the pump and valves, and some will soften rubber seals over time. Those are the docks that come into the shop with a pump that hums but doesn't move any water, and most of the time the fix is a proper clean rather than new parts. If you've got hard water, a monthly rinse of the clean tank with warm water keeps scale out of the lines.

How I picked these five

I started with what Amazon AU actually sells new between $900 and $2,500, through each brand's own Australian storefront or Amazon AU itself. All five picks are sold by Dreame Official AU, Roborock AU Direct or ECOVACS Robotics, and the T90 Omni's listing says it's the Australian version on 220 to 240 V with local warranty support. I ranked them by their Amazon AU Robotic Vacuums sales rank on 22 October 2026, where all five sat between #19 and #50.

I left two strong sellers out. The Dreame X60 Ultra was sold by Amazon AU at $1,795, but its listed model code ends in DE and the listing doesn't confirm an Australian plug or local warranty, so I'd rather not send you to it until that's clear. The Narwal Freo X10 Pro, also sold by Amazon AU at $1,499, was ranked #364 in the same category, well below everything here. Narwal's newer Freo 20 models had no rank published on the day I checked.

The lead pick is the ECOVACS T90 Omni, because it's the best-selling mop dock in the band and its listing is clear about local stock and warranty. If your floors are mostly hard and your couch is low, the Roborock Qrevo Edge 2 Set is the one I'd look at next. For wet cleaning without a robot, my wet dry floor cleaner guide covers the hand-pushed machines, and if a dock or robot stops working, the Erina repair counter can test it before you replace it.

Side-by-side comparison

What we see fail in the workshop: robot mop docks

Robot mop docks fail in more ways than plain robot vacuums, because they mix water, heat and electronics in one box on the floor. Most of what comes in falls into three groups: docks that stop moving water, batteries that can't finish a clean, and water getting somewhere it shouldn't. Here's what each looks like and what you can check yourself before paying for anything.

Decision tree: which one should you actually buy?

• Mostly hard floors and a busy kitchen? → The ECOVACS DEEBOT T90 Omni at $1,199, with its constantly rinsed roller mop and an Australian-version listing.
• Want the hottest mop wash without spending over $1,500? → The Dreame L50 Ultra AE at $1,200 washes its mops with 100°C water.
• Low couches and bed bases? → The Roborock Qrevo Edge 2 Set at $1,499 is 80 mm tall thanks to its retracting laser turret.
• Sliding door tracks and raised trims between rooms? → The Dreame X50 Ultra at $1,599 climbs up to 6 cm on retractable legs.
• Carpet, pets and a big house? → The Roborock Qrevo Edge 3 Pro at $1,999 leaves its mops in the dock for carpet and climbs the highest thresholds here.
• Dock won't pump water, robot won't charge or there's a puddle under the base? → Unplug it at the wall, check the tanks and seals, and clean the charging contacts. If it's still faulty, bring it to our Erina workshop and we'll test the pump, battery and boards before you replace anything.

Frequently asked questions

Is a robot vacuum and mop combo worth it over a plain robot vacuum?

It's worth it if most of your floors are hard and you'd otherwise mop at least once a week. A mop dock washes and usually dries the pads, empties the dust and refills the robot, so your job is down to emptying a dirty-water tank and topping up clean water. In mostly carpeted homes the mop barely gets used and a plain robot vacuum makes more sense. These docks also add more parts to look after: tanks, a pump, valves and often a heater. If you're not willing to empty the dirty tank a couple of times a week, the dock will start to smell and the convenience disappears.

Do I need hot water mop washing?

You don't need it, but it helps, mostly in kitchens. Hot water lifts cooking grease off the pads much better than cold water, and pads washed hot tend to smell less between runs. In this guide the Dreame L50 Ultra AE and Roborock Qrevo Edge 3 Pro wash at 100°C, the Qrevo Edge 2 at 80°C and the ECOVACS T90 Omni at 75°C according to its title. Warm-air drying after the wash matters just as much, because a damp pad in a closed dock is what causes the smell. The trade-off is a heater in the dock, which uses more power per wash and is one more part that can fail.

Can a robot mop go on carpet?

Yes, as long as it lifts or removes its mops first. Every pick here has some way of keeping wet mops off carpet. The Roborock Qrevo Edge 3 Pro leaves its mops in the dock for carpet up to 46 mm thick, the Dreame X50 Ultra has five carpet modes including lifting and removing the mops, and the ECOVACS T90 Omni uses its Triple Lift System. Carpet detection isn't perfect on dark or very thin rugs, so I'd still mark big rugs as no-mop zones in the app. Long shaggy rugs are best avoided entirely, because the brush can grab the fibres and the robot gets stuck.

Why does my robot mop dock smell?

Almost always it's the dirty-water tank or damp mop pads. Dirty water left sitting for a few days in a warm room goes off quickly, and pads that stay wet in a closed dock pick up a sour smell that ends up on your floor. Empty the dirty tank after every couple of runs, rinse it with warm water, and wipe the wash tray under the robot. Make sure the drying cycle is switched on in the app if your dock has one. Replace the pads when they stay grey after washing. If the smell hangs around after all that, check the tray filter for trapped hair and food scraps.

Do robot vacuums work on 5 GHz Wi-Fi?

Most don't. Both Roborock picks in this guide state on their listings that they only support 2.4 GHz Wi-Fi, and that's common across robot vacuums and other appliances. If your router broadcasts one network name for both bands, setup can fail because your phone is on 5 GHz while the robot is looking for 2.4 GHz. The usual fix is a separate 2.4 GHz network for appliances, or turning off 5 GHz for a few minutes while you pair the robot. Good signal in the far rooms matters too, as a robot that drops off Wi-Fi under a bed will miss schedules and lose map updates.

How long does a robot vacuum battery last?

In my experience, a lithium-ion pack in a daily-use robot vacuum starts showing noticeably shorter runtime somewhere around the two to four year mark, depending on how often it runs, how big the house is and how hot the room gets. A dock keeping it topped up isn't a problem in itself. Before replacing a battery, clean the charging contacts on the robot and the dock, because dirty contacts cause slow or failed charging that looks like a dead battery. When it does need replacing, use the maker's pack or a reputable one with proper protection circuitry, not a no-name pack with an inflated capacity figure.
