1. What Are the Key Differences Between the ROMO S, ROMO A, and ROMO P?
All three DJI ROMO models share the same core performance hardware: 25,000 Pa suction power, a 164 ml (5.5 oz) onboard water tank, and the identical sensor suite (dual fisheye vision sensors plus three wide‑angle solid‑state LiDAR modules). The differences are purely cosmetic and feature‑based:
-
ROMO S – All‑white chassis and base station. Minimalist design.
-
ROMO A – White base station with a transparent robot body. Allows you to see the internal components.
-
ROMO P – Fully transparent design on both the robot and base station. Adds a floor deodorizer compartment, a UV light inside the dust bag, and dual cleaning‑solution tanks (deodorizer + cleaner). Its base station also uses high‑pressure water jets (instead of standard self‑cleaning) and supports advanced mopping customization.
If you want the ultimate showpiece with extra hygiene features, the ROMO P is the choice. For identical navigation and cleaning performance with a more traditional look, the ROMO S or A deliver the same value.
2. How Does DJI’s Drone Heritage Translate into Obstacle Avoidance?
This is where the DJI ROMO truly stands out. The robot uses a sensor fusion system directly derived from DJI’s high‑end drones: dual high‑performance fisheye vision sensors for depth perception, plus three wide‑angle solid‑state LiDAR modules for 360° environmental mapping. Machine learning algorithms recognize over 10 object types in real time.
In practical tests, the ROMO reliably detects objects as thin as 2 mm (0.08 in)—charging cables, playing cards, shoelaces, cat toys, and even single pieces of paper. It navigates under beds and sofas with ease, and its wide field of view eliminates blind spots around irregular furniture. Professional reviewers have called it “the best sensor system in the industry” and “flawless obstacle detection.”
3. What Is the Real‑World Cleaning Performance?
The DJI ROMO delivers 25,000 Pa suction, among the highest in the premium robot vacuum category. On hard floors (tile, laminate, wood), it excels at removing fine dust, sand, oatmeal, and small debris. The extendable side brush and dual anti‑tangle rollers ensure thorough edge cleaning.
On carpets, performance is good but not class‑leading. The robot automatically boosts suction on carpet detection, and its dual rubberized rollers handle pet hair admirably. However, on high‑pile carpets, efficiency drops slightly compared to dedicated carpet specialists like Roborock or Dreame.
The mopping function uses a self‑cleaning base station that washes the mop pads with four high‑pressure water jets (12 N downward force) and a 16 mm (0.63 in) waste outlet, preventing dirty water from re‑contaminating floors. One limitation: the ROMO cannot lift its mop pads when crossing carpets, so edges may get slightly damp.
4. How Does the Self‑Cleaning Base Station Work, and Is It Truly Maintenance‑Free?
The DJI ROMO base station is a fully integrated hub that performs four key tasks automatically:
-
Empties the robot’s dust bin into a 2.4 L (0.63 gal) dust bag via suction.
-
Washes the mop pads using high‑pressure water jets and a scrubbing washboard.
-
Dries the dust bin and mop pads with warm air to prevent mold and odors.
-
Refills the robot’s water tank automatically.
DJI claims up to 200 days of maintenance‑free operation, though this refers to the washboard’s self‑cleaning, not the water tank or filters. In real‑world use, the system is highly reliable, but the dust bag may need more frequent changes in homes with multiple pets. Noise levels are reasonable: ~65 dBA during dust collection (80% noise reduction via a 3‑stage muffler) and ~40 dBA when drying.
5. How Long Does the Battery Last, and How Long to Recharge?
The DJI ROMO is equipped with a high‑capacity battery that provides up to 3 hours of runtime in standard vacuum mode. Recharging the battery takes 2.5 hours using the 55 W fast‑charging base station.
Real‑world endurance varies with suction level and mopping usage. In automated cleaning cycles (where the robot periodically returns to the base for emptying and pad washing), the ROMO can easily cover 200–300 m² (2,150–3,230 sq ft) per full charge—enough for most apartments and medium‑sized houses.
6. What Are the Physical Dimensions and Weight?
Understanding the size of the DJI ROMO is crucial to ensure it fits your space. Here are the official dimensions:
-
Robot: Approximately 35 × 35 × 9.8 cm (13.8 × 13.8 × 3.9 in). The height of 9.8 cm is taller than many competitors (which are often 7–8 cm), so it may not fit under very low furniture like some sofas or cabinets. However, the lack of a protruding LiDAR turret (LiDARs are embedded in the body) allows smoother passage in other areas.
-
Base station (ROMO P): 45.3 × 42.5 × 44 cm (17.8 × 16.7 × 17.3 in) – roughly the size of a mini‑fridge.
-
Robot weight: ~5.8 kg (12.8 lbs).
-
Base station weight: ~10 kg (22 lbs).
7. How Easy Is the Setup and App Experience?
Setting up the DJI ROMO is straightforward. The DJI Home app (available for iOS and Android) guides you through three steps: Wi‑Fi connection (the ROMO supports 5 GHz networks – a rare and welcome feature), base station pairing, and an initial “exploration tour” for mapping.
The app itself features a clean, minimalist interface with tabs for suction level, water flow, zone cleaning, schedules, and a real‑time camera view (which requires two‑factor authentication for privacy). Professional reviewers have praised the fast setup and logical layout, though some power users wish for more granular customization of cleaning maps. Overall, most users can go from unboxing to first clean in under 10 minutes.
8. How Reliable Is the Navigation and Mapping?
Navigation is where the DJI ROMO shines brightest. The fusion of fisheye vision + LiDAR creates a dense, real‑time 3D map that is stored locally on the device (not in the cloud), addressing privacy concerns. The robot:
- Remembers multiple floors (ideal for two‑story homes).
- Slows down near delicate objects (e.g., cat litter) to prevent scattering.
- Adapts routes on the fly when furniture is moved.
In extensive tests covering over 1,100 m² (11,840 sq ft) of cleaning, the ROMO never lost its position or required manual intervention due to navigation failures. This level of reliability puts it ahead of most competitors.
9. What Are the Most Common User Complaints?
No product is perfect. Based on aggregated user feedback from forums and review platforms, here are the most frequently mentioned drawbacks of the DJI ROMO:
-
No mop lifting – The robot cannot raise its mop pads when crossing carpets, leaving damp edges on rugs.
-
Small dust bag (2.4 L) – Requires more frequent changes than some 3 L+ competitors, especially in pet‑heavy homes.
-
Limited threshold climbing – Cannot cross thresholds higher than ~2 cm (0.8 in) without an optional accessory ramp.
-
Multi‑floor mapping glitches – A minority of users reported the robot failing to properly switch between stored floor maps (DJI has since released firmware updates).
-
Early privacy vulnerability – A now‑patched security issue allowed remote camera access; always keep firmware updated.
On the positive side, users consistently praise the “flawless obstacle avoidance,” “stunning transparent design,” and “never getting stuck.”
10. How Does It Compare to Competitors (Roborock, Ecovacs, Dreame)?
When stacked against premium rivals, the DJI ROMO has clear strengths and trade‑offs:
-
Obstacle detection – ROMO is class‑leading (detects 2 mm objects). Competitors are good but not as precise.
-
Suction power – 25,000 Pa is higher than most rivals (typical range 10,000–20,000 Pa, though some top models exceed it).
-
Mop lifting – ROMO cannot lift mop pads; many competitors (Roborock, Dreame) offer this feature.
-
Self‑cleaning base – ROMO’s high‑pressure water jets are excellent, but some competitors have similar systems.
-
Design – The transparent ROMO P is unique; others stick to understated white/black.
In short, the ROMO is a best‑in‑class navigator but not a best‑in‑class carpet cleaner. It is ideal for homes with many low‑lying obstacles and users who value smart automation over pure suction power.
Final Thoughts: Is the DJI ROMO Right for Your Home?
The DJI ROMO successfully transfers drone‑grade perception technology to floor cleaning. Its obstacle avoidance is unmatched, the self‑cleaning base station reduces manual work dramatically, and the transparent design is a conversation starter. However, the lack of mop lifting and average carpet performance means it won’t satisfy everyone.
This robot is best for: tech enthusiasts who want cutting‑edge navigation, pet owners dealing with scattered toys and cables, and anyone willing to trade a bit of carpet efficiency for zero get‑stuck frustration. If that sounds like you, the DJI ROMO is a fantastic choice.
