Robot vacuums have gone from novelty gadgets to genuine household staples, and the competition between the big three Chinese brands has driven quality up and prices down. I tested current models from Ecovacs, Roborock, and Dreame over six weeks in my Perth home, which has a mix of carpet, tile, and timber flooring, to see which one deserves your money.

The Contenders

I tested the Ecovacs Deebot X5 Omni, the Roborock S8 MaxV Ultra, and the Dreame X40 Ultra. All three sit in the premium bracket between $1,500 and $2,200 AUD, and all three come with auto-empty docking stations that also handle mop washing and drying. These are the flagship models each brand offers in Australia right now.

Navigation and Mapping

All three use LiDAR navigation combined with camera-based obstacle detection, and honestly, all three are good at it. The Roborock was marginally better at avoiding small objects like charging cables, while the Ecovacs had the fastest mapping speed when setting up a new home map. The Dreame fell slightly behind in obstacle avoidance during my testing but was still competent.

Room mapping was accurate across all three. Each app lets you set no-go zones, room-specific cleaning schedules, and different suction levels per room. The Roborock app feels the most polished, but it’s a minor advantage.

Cleaning Performance

On carpet, the Roborock S8 MaxV Ultra had the strongest suction and picked up the most debris in my standardised tests. I scattered measured amounts of rice, flour, and pet hair equivalent across identical carpet sections and weighed the dustbin contents after each run. The Roborock consistently collected about 5-8% more material than the other two.

On hard floors, the differences were negligible. All three did an excellent job picking up dust and small debris. The mopping function is where things got interesting. The Dreame X40 Ultra uses a rotating mop that applies more pressure to the floor, and it consistently outperformed the other two on dried coffee stains and scuff marks. The Ecovacs was close behind, while the Roborock’s mopping was adequate but not as aggressive.

It’s interesting to see how AI strategy support is starting to influence even consumer electronics, with these brands using machine learning for smarter navigation patterns and cleaning route optimisation. The improvements over models from just two years ago are noticeable.

Noise Levels

I measured noise levels at one metre distance during standard cleaning mode. The Dreame was the quietest at around 62 dB, followed by the Ecovacs at 65 dB, and the Roborock at 67 dB. In practice, all three are quiet enough to run while watching television, though you’ll notice them in the room.

Dock Station Comparison

The docking stations are massive for all three, so make sure you have space. The Ecovacs dock is the most compact, while the Dreame dock is the largest. All three handle auto-emptying, mop washing, and hot air drying. The Roborock dock adds a self-cleaning function that keeps the dock internals fresh, which is a nice touch.

Where to Buy in Australia

All three are available through Amazon AU, and Roborock and Ecovacs are stocked at JB Hi-Fi and The Good Guys. Dreame has less physical retail presence but is readily available online. Warranty support is 12 months standard for all three, with Roborock offering the most responsive Australian customer service in my experience.

The Verdict

If I had to pick one, the Roborock S8 MaxV Ultra is my recommendation for most Australian homes. It offers the best overall cleaning performance, the most refined app, and solid after-sales support locally. The Dreame X40 Ultra wins on mopping and is the quietest, so it’s worth considering if hard floor mopping is your priority. The Ecovacs Deebot X5 Omni is the most compact and has a good balance of features, making it a solid middle-ground choice.

All three represent genuine improvements over their predecessors, and you won’t be disappointed with any of them. The real question is which specific strengths matter most for your home.
