DJI ROMO S vs P vs A: Differences, Features & Canada Buying Guide

DJI ROMO S vs P: both offer up to 25,000 Pa suction. ROMO S has a white robot and station; ROMO P has a transparent robot and station, plus floor-deodorizer support and a dust-bag UV light. ROMO A pairs a transparent robot with a white station. Compare the water tank models below to decide whether the flagship station features matter to your routine.

ROMO P, A and S share DJI’s approach to automated floor cleaning, but the differences are worth understanding before you choose. Relia carries the water tank configuration of each model.

Start with what they share

All three combine up to 25,000 Pa suction with obstacle sensing, dual extendable robotic arms and a self-cleaning base station. The core decision is therefore about design and model-specific equipment, rather than simply choosing a higher suction number.

Three designs, three price points

ROMO S keeps the look understated. ROMO A adds a transparent robot housing and a bristle-and-rubber brush configuration. ROMO P makes the internal design visible in both the robot and station, and supports a floor deodorizer compartment and a dust bag UV light.

What does Water Tank Version mean?

The station uses refillable clean-water and wastewater tanks. You will still need to refill, empty and care for the system. Choose the station location with that routine in mind: leave access to the tanks and enough room for the robot to move in and out.

Plan around your home

Consider your floor mix, the space available for the station and where everyday clutter tends to collect. Sketch a possible station position before buying, and make sure it works with the setup instructions for your supplied regional version.

Obstacle sensing and cleaning results depend on lighting, surfaces, layout and settings. Follow the manual for safe setup and maintenance; an automated schedule does not eliminate routine care.

DJI ROMO S vs P: what does the extra cost buy?

At the Relia prices reviewed on October 13, 2026, ROMO S is CAD $1,499.99 and ROMO P is CAD $2,099.99 before tax: a CAD $600 difference. The advertised suction figure is the same. The decision is about P’s transparent station design and its additional deodorizer and UV functions, rather than a higher suction rating. Choose S if those extras are not priorities; compare P if they are. These features do not replace routine cleaning and care.

Where does ROMO A fit?

ROMO A is CAD $1,799.99 before tax at the time of review. It sits between S and P in price and pairs the transparent robot with a white station. It does not include P’s floor-deodorizer and dust-bag UV functions. Check each exact listing’s included items before ordering.

Quick buying questions

Do these models need a permanent water connection?

The water tank versions listed by Relia use refillable tanks. Automatic supply and drainage hardware is not included. Confirm space for the station and easy access to refill and empty the tanks.

Does the P model clean every home better than S?

A higher price alone does not establish a better result in your home. Floor types, obstacles, settings and maintenance affect performance. Compare the specific station functions you want instead of treating the price tier as a cleaning guarantee.
