The new Ecovacs Robotics DEEBOT NEO 4.0 packs a punch at an affordable price point. You’ll be able to pick one up for just $279 in the upcoming Aldi sale starting 5 September 2026. With 11,000Pa suction, ZeroTangle 2.0 anti‑tangle technology with its V‑shaped brush, accurate obstacle detection, and both vacuuming and mopping capabilities, this robot vacuum could be exactly what you need if you’re building a smart home on a budget. It advertises real‑time home mapping to optimise cleaning routes and deliver efficient autonomous cleaning across your home.
To be honest, I genuinely think robot vacuums are a must‑have modern convenience. The ability to set schedules for “maintenance cleans,” as Kevin and I call them, is a game changer. At this price, having one within the home is within reach for more people. I’ve had the Ecovacs Robotics DEEBOT NEO 4.0 running in my main living area for the past couple of weeks, so let’s see how it performs in the real world. Is it “The One”?
The Initial Setup of the Ecovacs Robotics DEEBOT NEO 4.0
I get to play with a lot of random tech through DRN, so sometimes I misjudge how easy something is to set up. This robot vacuum, however, is genuinely simple.
The base station was the first thing I noticed when unboxing. At roughly 100mm high, 50mm deep and 220mm long, it’s small and won’t take up much room. It features two metal charge contacts and that’s it — plug in the cable and you’re halfway done. The rear of the base has a spot to wind excess cord, and two little detachable spaces to allow it to sit neatly against skirting boards.
The vacuum itself has a bit of weight, as they all do, with decent wheels to navigate minor changes in flooring levels (boards to carpet, but not steps). You’ll need to attach the sweeping side brush, which clicks in easily, and at that point you’re ready for the final setup steps.
Under the lid, you’ll find the removable dust bin — this is a bagless vacuum — and the removable water tank at the rear. You can also attach the mopping pad, though none of this is required immediately.
Final step: install the app, create an account, tap “Scan to Connect,” scan the QR code on the vacuum, and follow the prompts. You’ll press a couple of buttons on the unit, enter your Wi‑Fi details, update the firmware, and you’re away.
First Mapping Run and Navigating Your Home
Mapping your home is the first job.
This unit is a solid performer at $279, but that price point also means you shouldn’t expect it to climb steps or do anything wild. I have a 25mm lip between my dining room and kitchen. At 25mm, you would not think it is much (unless you kick it barefoot at night…), but the Ecovacs Robotics DEEBOT NEO 4.0 will not climb it. Won’t even consider it. Positioning is key to ensure it covers the majority of your home.
On that note, I have some pretty thick plush-pile carpet. Even the step from the timber boards up onto the carpet in the lounge is a bit of a struggle at times. It always manages to get up, but it sometimes judders back and forth to get up over the lip of the carpet.
Sending it out to map is easy through the app, which gives you best‑practice tips. Clear toys and clutter, close doors you don’t want it entering, and let it go. The mapping is adequate, but not great.
On its first pass, it struggled with my layout. My dining room connects to the hall and a semi‑open loungeroom, and it mapped all of it as one giant room, despite the lounge being carpeted with two doors. It also somehow added half my master bedroom into that room during the original map, with each side of the bed as separate rooms.
After mapping, though you can divide and combine rooms in the app, and set no‑go and no‑mop zones — the latter is essential, otherwise the vacuum will wander with the mop attached and struggle to move.
After some fiddling, the map was more than adequate.
One thing worth noting: your mapping is what you get. When I originally mapped, I had boxes along one wall in the dining room. After removing them, the vacuum still behaved as though they were there, not adjusting or remapping the newly open space. Not a big deal, but worth mentioning. If you do something like that, you will just have to remap.
Day‑to‑day use with the Ecovacs Robotics DEEBOT NEO 4.0
If the mop pad isn’t attached, the Ecovacs Robotics DEEBOT NEO 4.0 defaults to vacuum only. As it moves around, it picks up a noticeable amount of dust and debris with ease. When testing these units, I deliberately “mess” my house. The little bits of grass I walked in on my shoes? Gone. The bread crumbs from my plate that I deliberately poured on the dining room floor? Gone. The fluff I picked off my socks and threw on the lounge room carpet? Gone.
It will work its way around the house and do a solid job getting close to walls and furniture without issue. It does sit reasonably high, with the LiDAR detection unit sticking up, so this won’t easily get under any low beds or couches (where other robot vacuums I have used have managed to squeeze under). But where it goes, it cleans well.
There are multiple power modes — Quiet, Standard, Strong and Max. Quiet is genuinely reasonable and can be used at night if you’re in another room. You’ll still hear it, but it’s not excessive. I tend to run mine on Quiet when I’m home and it does a good job. Max gets quite loud, but does really ramp up the suction power as one would expect.
Overall, I’ve been happy with its performance on normal day‑to‑day mess.
I should disclose that I don’t have pets. How this unit would handle heavy pet hair from a shedding animal, I’m unsure, so bear that in mind.
Robot vacuums are game changers for busy lifestyles. Set up a schedule in the app and your house will be vacuumed while you’re not home. For someone like me with sinus issues, it’s great for keeping dust manageable. Will you still need to drag out a stick vacuum or properly mop from time to time? Absolutely. Robot vacuums don’t replace cleaning — they make it far more manageable.
For everyday cleaning at this price point, you won’t be disappointed. But how does it handle more intense tests?
The Flour Test
I always regret this test, but I do it anyway. Flour is a great indicator of what a robot vacuum picks up and what it spreads around. It’s also not a fair test — you wouldn’t send a robot vacuum out to clean a pile of flour or sand or dirt you just poured on the floor — but on we go.
I poured a decent amount of flour on my timber boards, set the Ecovacs Robotics DEEBOT NEO 4.0 to Strong, and sent it out.
It tends to start with the perimeter, then moves through the centre of the room. It did an admirable job. I’ve seen other units do better, but it still performed well. The only real issue was that driving through the flour caused some to stick to the wheels and spread slightly.
After one pass, it had cleaned most of it. A second pass mostly finished the job, though I did need to use my stick vacuum for a few stubborn spots.
Again, remember the price point. Overall, a good job. (The photos below after just one pass.)
The Shredded Paper Test
My shredder does cross‑cut shredding, which gives a great carpet test as the tiny pieces settle deep into the fibres.
Setting the Ecovacs Robotics DEEBOT NEO 4.0 to Max, I was impressed. On Max, the suction ramps up (and so does the noise), so it’s not ideal at midnight (sorry neighbour!). You also wouldn’t want to run Max across the whole house as it drains the battery faster.
Attacking the shredded paper, it systematically worked through the mess. A few tiny pieces were left after the first pass, mostly those blown out of its path, but the majority was cleaned up. After a second pass, the room was spotless.
I was really impressed with this cleaning job, even more so for the price point. Really solid performance. (The photos below after just one pass.)
Bagless Dust Collection
Just drawing attention to this again: no dust bags with the Ecovacs Robotics DEEBOT NEO 4.0. All dust, fluff and dirt is collected in the internal dust bin. Pull it out, open the filter door, and empty it into your garbage. Less consumables is always a win.
Ecovacs Robotics DEEBOT NEO 4.0 detecting and avoiding obstacles
Before I get to the mopping, let’s talk obstacles. At $279, you’re not getting the greatest technology in the world. The Ecovacs Robotics DEEBOT NEO 4.0 advertises “millimetre‑level obstacle detection,” and it does detect obstacles and slow down as it approaches them. But in truth, it’s a bit of a drunk at times.
It uses LiDAR for mapping and navigation. As it approaches an obstacle — for example, the couch, table leg, wall — it slows dramatically within millimetres and gently nudges its way around. The front bumper gives it tactile feedback.
It does the same to detects and avoid obstacles, but not always gracefully. I left my slippers against the wall during one test. The Ecovacs Robotics DEEBOT NEO 4.0 detected them, slowing as it approached, then when it stumbled into them. It slowed, nudged them, corrected course, nudged them again, and shifted them around. The slippers were moved into a different spot by time it was around them.
Not terrible, but if it were a cup left on the floor by a little one, there may have been spilt milk to deal with, too.
Similarly, it didn’t cope well with the towel I had rolled up along my front door to stop a draught. It nudged it into the corner, then tried to climb into it and nest, tangling itself. Untangling was easy, I put the towel away, and put the vacuum back on the floor. I then simply the power button, and off it went again.
Moral of the story: clear your floors of cables, towels, socks and jocks before sending it out.
Overall, though, it does a good job. The bumps are extremely light, so I don’t expect issues with furniture.
Mopping
The Ecovacs Robotics DEEBOT NEO 4.0 does have a mopping feature. There’s a removable water tank and a large cleaning pad that clips onto the back. The pad doesn’t move or spin, clean itself or lift when moving onto carpet. It simply trails behind the unit, wiping the floor.
In the past, I’ve poured orange juice on the floor for mopping tests. I didn’t do that here — I could already picture the smear and the cleanup. You shouldn’t send a robot vacuum to clean spills anyway. Wipe first, then let the robot mop.
But this brings it back to how mapping is essential. The unit doesn’t differentiate between carpet and hard floors. It increases suction on carpet, but unless you’ve set no‑mop zones, it will drag the mop pad across carpet, getting it slightly wet and causing extra friction.
A no‑mop zone means the unit won’t clean that area if the mop is attached. And enabling or disabling mopping is manual — you must physically attach or remove the pad each time. If the mop is on and you want to vacuum the carpeted bedroom, it won’t go there if it’s marked as a no‑mop zone.
For me, I wouldn’t advocate this unit for mopping if you have a mix of carpet and hard floors. If your house is all boards or tiles, mop away!
That said, cleaning the pad is easy. Pull off the plate, remove the mopping cloth from Velcro, slide it out, wash and dry.
The Ecovacs Robotics App
The Ecovacs Robotics app is one I like, but sometimes dislike.
Mapping flexibility isn’t great if you have an unusual floor plan. Setting no‑go and no‑mop zones is easy, but dividing rooms can be tricky with only straight lines between walls allowed. The ability to draw a square to designate a room or zone would be great.
You can do an auto‑clean, where the Ecovacs Robotics DEEBOT NEO 4.0 will just venture out and do its thing, or you can select rooms on the map to just clean those. Whether the mop is attached determines whether it vacuums only or vacuums and mops. Changing suction, water flow and number of passes is simple.
Schedules are extremely easy to set.
If you have multiple Ecovacs units, switching between them is seamless.
The only annoyance is the pop‑up that takes you to the shop to buy consumables (side brushes, mop clothes, etc for this unit). It seems to get slightly bigger during sales. Not a deal breaker, but I do bump it occasionally.
The app is fine. Not the snappiest, but it serves its purpose. Once you set a schedule, you won’t need to open it often.
A Lost Vacuum?
There have been times I’ve had to pick up and move the vacuum, especially after adding or removing the mop pad. Sometimes it struggles to figure out where it is.
If you can’t see the Ecovacs Robotics DEEBOT NEO 4.0 on the map, the best solution is to place it back on the charger and send it on an Auto Clean. It finds itself quickly and carries on.
The Voice
A brief note, but I like the voice. It’s pleasant enough and gives clear updates when it’s completed something or needs help. I’m amused by the “Off the floor… Please put me back!” cry when you lift it.
Final Thoughts on the Ecovacs Robotics DEEBOT NEO 4.0
If you don’t have a robot vacuum in your life, you really don’t know what you’re missing.
If you’re venturing into the world of robot vacuums, the Ecovacs Robotics DEEBOT NEO 4.0 is a superb option. Solid vacuuming performance, adequate mopping (though cumbersome with the manual setup each time, easy app use and scheduling, and above all, affordability. At just $279 at Aldi from 5 September 2026, I highly recommend the Ecovacs Robotics DEEBOT NEO 4.0 for your first — or next — robot vacuum cleaner.
Thank you Ecovacs Robotics for the use of the unit the past few weeks.
