Our verdict in 30 seconds

Daily floor care takes priority over weekend catch-up with DJI Romo A

The Romo A combines rotating mop discs, carpet mop lifting, and a station that empties, washes, and dries. We favor it for homes where vacuuming and wet cleaning compete for your evening. Its small onboard dustbin makes regular attention especially relevant when pet hair accumulates.

Verdict

8.7/10

We favor Romo A for floors that need regular attention

The shoes come off after work, and floor care should not become the evening's main event. We like the Romo A's combination of rotating mops, carpet lifting, and station care. Its overall rating falls within the site's top group. Less chasing crumbs, more getting on with home.

Our verdict: We recommend it for busy homes that will use both vacuuming and mopping regularly. Make room for the station and keep brush and pad maintenance in the routine, particularly when pets supply a steady stream of hair.

Things to bear in mind Avoid it if independently measured cleaning results are essential to your decision: its ability to remove dirt has not been independently established here.

Review by Romain Brunel, founder of Robot Vacuum Picks

Who it's for

A pet household gives Romo A plenty of useful work

  • Pet households with regular floor care needs
  • Homes combining rugs and mop-friendly hard floors
  • Busy households wanting station-assisted maintenance
  • Multistory homes needing saved floor maps

This model suits a household where grit reaches the hallway, snack crumbs land beneath the table, and hard floors need regular mopping. Coming home from work to floors already attended to is the attraction. Its mapping options also suit rooms with different cleaning boundaries and homes where the robot needs to be carried between floors.

Less suitable if

Skip it if you want an appliance you can ignore indefinitely. Brushes, mop pads, and the station still need care, especially with pets around. A home without a convenient place for the dock should settle that placement question before ordering.

Our scores explained

Every model on the site is scored on the same criteria, using the same scale for all: its position among models with a verified specification. Last place scores 6.5, first place 9.6, with the rest scored proportionally by rank. Here's how this model's scores were calculated.

Two groups: the rank and average count models with site profiles scored on this criterion; the calculation compares this model with all catalogue models with the specification verified, with or without a profile. A score assigned at publication may remain without a verified specification, so the first group can sometimes be larger.

Our full methodology

Detailed analysis

The entryway collects grit while you are at work, and the kitchen floor rarely takes the afternoon off. The DJI Romo A brings strong advertised suction, rotating mops, and a station that empties, washes, and dries into that daily routine. Its appeal is practical: coming home with less floor care waiting. The decision turns on how well that feature set fits your rugs, household clutter, and appetite for upkeep.

The Romo A robot vacuum pairs 25000 Pa with a small bin

The DJI Romo A puts a substantial suction figure behind a familiar ambition: getting the rug cleaned before you get home from work. Its advertised 25000 Pa sits among the strongest suction figures, giving it a potential advantage where dog hair collects between rug fibers. That is a promising specification, not a promise of a clean rug. Manufacturers measure suction differently, so the number cannot settle the cleaning question by itself.

Does your living room rug collect more fur than your dog seems to have? The bristle and rubber main brush gives this pet-friendly model a relevant configuration, while 2 side brushes help gather debris toward the cleaning path. The catch is its 260 mL onboard dustbin: small enough that accumulated pet hair can require frequent emptying. The station handles emptying, but the robot's container still deserves attention when shedding season arrives.

A 180 min run gives the Romo A room to work through the house

A recommended maximum area of 178 m² puts this robot in the conversation for a house with several living spaces. Think of the hallway grit brought in through the garage, crumbs beneath the dining chairs, and dust gathering in the spare room. Coverage describes the overall assignment, not an uninterrupted cleaning run. Recharging and resumed cleaning can be part of reaching that area.

The stated 180 min runtime supports the prospect of several rooms in a continuous run, although that figure comes from the gentlest mode. Stronger suction or mopping shortens it. A 2.5 h charging time means a relatively quick recharge between runs, and recharge and resume lets the robot continue its route afterward.

We see the strongest fit in regular maintenance across a busy house. Letting dirt accumulate until the weekend gives any cleaning routine a harder job. Your Saturday can have better plans.

Rotating mop discs and 3-in-1 station (emptying + washing + drying) share the wet work

A splash beside the kitchen sink and dusty footprints across the adjoining hardwood call for more than dry pickup. Rotating mop discs give the Romo A an active mopping system, making its wet cleaning proposition more substantial than simply dragging a damp cloth. We like the combination of floor care and station maintenance because both affect how much work remains for you.

Mop lifting on carpets is especially relevant to mixed flooring. It is intended to let the robot transition from kitchen tile toward a living room rug while keeping the wet pads raised. That feature does not establish compatibility with every rug thickness.

The 3-in-1 station (emptying + washing + drying) combines emptying, mop washing, and drying. Those are recurring chores worth handing over. Before ordering, confirm dock dimensions, replacement bags, pads and brushes, warranty coverage, repair support, return terms, and any app subscription with the retailer; those ownership details are missing here.

Maps help the Romo A robot vacuum organize cleaning around your home

Laser and camera navigation give this robot a mapping system, supported by 3D obstacle detection. That combination is relevant when rooms contain chair legs, furniture, and the usual household clutter. It does not make preparation optional. Following manufacturer instructions, clear charging cords, socks, and small objects before a run. The laundry still needs a human department.

Would you rather keep the robot away from a craft corner altogether? No-go zones let you mark an area it should leave alone. That is a useful way to organize cleaning around a room's purpose instead of rearranging everything whenever the floors need attention.

Multi-floor mapping also makes sense for a multistory home, with you carrying the robot between floors. It stores the layouts; it does not handle the stairs. Connectivity includes Wi‑Fi 2,4 GHz, Wi‑Fi 5 GHz, Bluetooth, giving you several supported connection options without establishing any particular voice assistant compatibility.

Our DJI Romo A review favors routine care over suction headlines

Choosing this model should start with the chore you want removed from your week. For a home that needs both vacuuming and rotating mop care, its station and carpet mop lifting form a coherent package. If your priorities are mainly dry pickup and minimal equipment beside the wall, think carefully about how much of that package you will actually use.

The published 65 dB noise level is around average, so we would schedule cleaning for errands or work rather than build a quiet evening around it. A cleaning schedule should fit your household, not negotiate with it.

It sits in the site's top group for its overall score. That reflects the appeal of the complete feature set. We would still make rug needs, available dock space, and willingness to maintain brushes central to the decision. A dramatic suction figure cannot answer those practical questions for you.

Frequently asked questions

Your practical questions about the robot vacuum before ordering

Can the Romo A mop hard floors and move onto rugs?

It has rotating mop discs and mop lifting on carpets. That combination supports cleaning mixed flooring while raising the wet pads over rugs. It does not establish compatibility with every rug thickness. For unfinished, waxed, or poorly sealed hardwood, follow manufacturer advice about moisture suitability.

Can the Romo A cover a house without stopping?

Its recommended maximum coverage is 178 m², which suits a house with several living spaces. That coverage can involve recharging and resumed cleaning. Runtime is measured in the gentlest mode, and stronger suction or mopping reduces how long a continuous run lasts.

What maintenance should I plan for before buying?

Plan to maintain the main brush, side brushes, mop pads, and station. Emptying, mop washing, and drying are handled by the dock, but accumulated hair and worn cleaning parts still need attention. Check the replacement supply arrangements discussed above before ordering.

Does obstacle detection mean I can leave clutter out?

The robot includes laser and camera navigation with 3D obstacle detection. Follow manufacturer preparation instructions anyway: remove cords, socks, and small objects before cleaning. No-go zones also let you exclude a designated area from its route.
