Ecovacs vs Roborock

Both make excellent robots at every price point, so the real decision comes down to mopping style, app polish, and which flagship dock actually suits your home.

The two biggest names in robot vacuums, head to head

If you have shopped for a robot vacuum in the last couple of years, you have run into these two brands constantly, often at near-identical price points with near-identical spec sheets. Both make genuinely excellent robots across every price tier, from sub-$500 basics to flagship models pushing $3,000-plus with full auto-empty, auto-wash, auto-dry docks. The differences that actually matter come down to mopping mechanism, navigation reliability, app polish, and - increasingly - which one has better after-sales support in NZ.

Mapping and navigation

Roborock's flagship line, including the Saros 10R, uses a retractable LiDAR turret - the laser mapping unit pops up when needed and tucks away so the whole robot can slim down to 3.14 inches tall and duck under low furniture that stops most other robots dead. This is a genuinely clever piece of engineering that solves the classic trade-off between LiDAR accuracy and physical clearance.

Ecovacs uses a combination approach on its flagship X-series (the X11 OmniCyclone and X9 Pro Omni), pairing LiDAR with AI-assisted 3D obstacle recognition (branded AIVI) that identifies and avoids cables, pet waste, shoes, and other floor clutter with genuinely impressive accuracy. Both brands' flagships build reliable, accurate floor maps and support multi-floor mapping, no-go zones, and room-by-room scheduling in their apps. At the budget end, both brands' cheaper models step down to gyroscope-and-camera navigation that is noticeably less precise - if navigation accuracy matters to you, do not buy either brand's entry-level tier expecting flagship-level mapping.

Self-empty base and hands-off maintenance

Both brands' flagship docks now do genuinely everything: empty the dustbin into a sealed bag, wash the mop pads or roller with hot water, dry them with hot air to prevent mould and odour, and refill the onboard water tank for the next mopping run. Roborock's dock designs tend to be a touch more compact; Ecovacs' OmniCyclone base emphasises bagless dust collection on its newest flagship, which removes the recurring cost of replacement dust bags entirely - a genuine ongoing-cost advantage if you pick that specific model over a bagged equivalent from either brand.

Suction and cleaning performance

Independent testing consistently finds both brands' flagships remove 95 percent or more of debris across hard floors, low-pile and mid-pile carpet - genuinely excellent, and close enough that the headline Pa numbers (Roborock's 22,000Pa vs Ecovacs' 19,500 to 16,600Pa depending on model) do not translate into a noticeable real-world cleaning gap on most NZ homes' floors. Where the gap does show up is thick, deep-pile carpet and pet hair tangling around brush rolls - Roborock's zero-tangle brush design and Ecovacs' equivalent anti-tangle comb both perform well, though Roborock's has a slight edge in the most recent independent testing.

Price tiers and value

Both brands span an enormous price range, from around $250 to $400 entry-level models with basic gyroscope navigation and no mopping automation, right up to $2,000 to $3,000-plus flagships with the full self-empty/wash/dry experience. At the budget end there is genuinely little to separate the two brands - pick whichever is cheaper on the day for a comparable spec. At the flagship end, the choice comes down to which mopping mechanism you prefer (sonic scrubbing/spinning pads from Roborock vs self-washing roller from Ecovacs) more than raw cleaning ability, since both are excellent.

Debunking the myth: higher Pa suction always means better cleaning

Robot vacuum marketing leans hard on Pa (pascal) suction ratings, and it is tempting to assume Roborock's 22,000Pa flagship must out-clean Ecovacs' 19,500Pa or 16,600Pa models by a wide margin. In practice, independent lab testing repeatedly shows all of these flagship robots removing 95-plus percent of debris across common floor types - the gap in Pa rating does not translate proportionally into a gap in actual dirt pickup, because brush roll design, dock suction assist, and how well the robot's wheels maintain contact with the floor all matter just as much as the peak vacuum motor number.

Verdict: who should buy which

• Buy Roborock if: you want the most powerful and customisable mopping system, you like tinkering with app settings and scheduling, and you have thick carpet or heavy pet hair to deal with.
• Buy Ecovacs if: you want a simpler first-time robot vacuum experience, you care about mop hygiene (the self-washing roller genuinely reduces that damp-mop smell), and you want a slightly friendlier app.
• Small apartment, budget-conscious: either brand's sub-$500 tier does a genuinely solid job on straightforward, low-clutter floor plans - do not overspend on a flagship if your home is a one-bedroom apartment with mostly hard floors.
• Large house, heavy pet shedding: go flagship from either brand and prioritise the self-empty, self-wash dock - at this size and mess level, the hands-off maintenance is worth the extra spend regardless of which brand you choose.
