DJI Romo S brings pet hair cleanup into focus

The Romo S pairs substantial suction with an anti-tangle main brush and carpet mop lifting. We see a convincing fit for pet owners managing everyday floor debris. Its appeal rests on regular upkeep, with preparation and maintenance still part of the arrangement.

Verdict

8.9/10

We recommend this robot vacuum for regular floor upkeep

Less fur around the couch and more evening left for yourself: we like the Romo S for that everyday ambition. It ranks among our strongest overall choices. Let the robot handle the repetition.

Our verdict: We recommend it for pet owners who want regular vacuuming support across mixed flooring and accept the upkeep that comes with it. If removing stuck residue is your main goal, keep a manual mop ready rather than expecting automation to take over that chore.

Things to bear in mind Avoid it if you expect its mop to remove persistent kitchen stains without your help. You will still need to scrub those yourself.

Who it's for

Romo S makes sense when pet hair keeps coming back

  • Pet owners managing recurring loose hair
  • Homes combining rugs with hard floors
  • Households seeking help with regular floor upkeep

This robot fits households where pet hair gathers faster than anyone wants to vacuum. If your evening usually includes a pass around the couch before you can relax, its suction specification and anti-tangle main brush make sense together. Carpet mop lifting adds practical appeal when the route between the kitchen and living room crosses different flooring.

Less suitable if

Skip this model if you want floor care to require no preparation or maintenance. You still need to clear loose items before cleaning and inspect the brush regularly. Its suction figure also should not decide the purchase if your main concern is pickup on a particular thick rug.

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.

Charging time: 9.1/10

DJI Romo S scores 9.1/10 on this criterion. Across the 9 product listings on the site with a score for this criterion, the average is 8.2: above average, 2 of 9.

Our full methodology

Detailed analysis

The dog tracks through the living room, someone eats crackers on the couch, and suddenly the floor needs attention again. The DJI Romo S addresses that recurring chore with substantial stated suction, an anti-tangle main brush, and a mop that lifts on carpets. Its appeal is practical: less vacuuming competing with your evening. The buying decision comes down to how much help you want with pet hair, mixed flooring, and everyday upkeep.

The Romo S robot vacuum review starts with the rug

A living room rug can look presentable until the dog gets up and leaves a fuzzy outline behind. The DJI Romo S brings 25000 Pa of stated suction to that familiar problem, placing it among the strongest published figures and suggesting a potential advantage on rugs. We like the ambition. Manufacturers measure suction differently, though, so that figure helps position the robot without telling you how much hair will leave your particular rug.

The anti-tangle main brush is another relevant detail for homes with pets. Its design targets hair wrapping around the brush, a maintenance chore that can otherwise make automated cleaning feel less automatic. Brush checks still belong in your routine. The 2 side brushes add to the pickup arrangement, but their count cannot tell you how thoroughly crumbs beside a cabinet will be collected. Your dog remains exempt from cleanup duty, apparently.

Can the Romo S robot vacuum fit cleaning around your workday?

Would coming home to already cleaned floors make dinner feel less rushed? A stated runtime of 180 min suggests enough endurance for a long cleaning session across several rooms. That makes it appealing for a routine built around your workday, with crumbs beneath the dining chairs and loose hair in the living room on the agenda.

Keep that duration in perspective. The manufacturer's runtime reflects the gentlest operating mode; increasing suction or using the mop draws more from the battery. It cannot tell you the floor area a charge will cover, especially when room layouts and cleaning settings change.

The charging time of 2.5 h suggests a quick recharge between cleaning runs. For a household fitting floor care between breakfast and an evening gathering, that is useful scheduling context. Leave room in your plans for charging, rather than expecting the headline endurance at every setting.

Romo S lifts its mop when the floor becomes a rug

Kitchen tile and a living room rug ask for different treatment during the same cleaning session. The Romo S supports mopping and raises its mop on carpets, a useful feature when your home mixes hard flooring with soft surfaces. You should not have to organize your entire decorating scheme around a cleaning appliance.

We see the mopping function as help with routine floor upkeep. Keeping everyday residue in check is an appealing prospect when you walk into the kitchen wearing socks. But routine mopping leaves stubborn marks for manual cleaning. Dried mess beside the stove still calls for your involvement; automation has limits even when the floor plan cooperates.

Mop lifting does not establish which rug thicknesses will suit the robot. For unfinished, waxed, or poorly sealed hardwood, manufacturers advise checking moisture tolerance before using a mop. That check matters more than the convenience of combining chores in a cleaning run.

No-go zones give Romo S a boundary around the pet bowls

A water bowl beside the kitchen doorway can turn a convenient route into a place you would rather exclude. No-go zones let you set boundaries, giving you a practical way to keep a designated area outside the cleaning routine. That is useful control for a home where the floor serves as a pet dining room, a play space, and a path to the couch.

App compatibility and Bluetooth connectivity are confirmed features. A phone interface will appeal if you prefer managing appliances through an app. Bluetooth alone, however, is no reason to assume you can operate the robot while away from home.

Room preparation remains part of the arrangement. As manufacturer instructions require, clear charging cords, socks, and small objects before a cleaning run. A quick look beneath the dining chairs can become part of leaving the house, alongside grabbing your keys. The robot gets a clearer floor, and yesterday's abandoned sock gets another chance at the laundry basket.

DJI Romo S makes its clearest case in a house with pets

Need a robot chiefly for loose hair and recurring crumbs? The combination of substantial suction, an anti-tangle main brush, and carpet mop lifting makes a coherent case. In our overall assessment, it sits among the site's strongest choices. That standing supports consideration, while your flooring and willingness to maintain the appliance should settle the decision.

For a home dominated by rugs, give the brush design and suction specification particular weight. In a house with kitchen tile and living room hardwood, the mopping function becomes more relevant. Choose around the chore that interrupts your day most often; a longer feature checklist does not automatically make daily life easier.

Before ordering, ask the retailer about the dock's emptying, mop washing, drying, and floor space, plus replacement bags, pads, and brushes, warranty, customer support, repairs, returns, and any app subscription. Those purchase details need confirmation. Knowing where the equipment will sit and how you will maintain it matters when you are trying to remove a chore from your week.

Frequently asked questions

Your questions about living with this robot vacuum

Does the Romo S make sense for a home with pets?

Yes, its pet-focused use and anti-tangle main brush make it relevant to recurring hair cleanup. The substantial suction specification also supports consideration for rugs. Expect to inspect the brush regularly rather than treating the anti-tangle design as freedom from maintenance.

Can Romo S mop hard floors and travel over carpets?

It supports mopping and lifts its mop on carpets, which is useful in homes with mixed flooring. Mop lifting does not establish suitability for every rug thickness. Check moisture tolerance before mopping unfinished, waxed, or poorly sealed hardwood.

How should I interpret the stated runtime?

The stated 180 min suggests a long cleaning run across several rooms under gentle operating settings. Higher suction and mopping use more battery, so allow for shorter sessions when you use those functions. The duration is not a promise about how much of your house gets cleaned.

What maintenance should I plan for before ordering?

Plan to inspect the main brush, remove accumulated hair or debris, and keep mop pads clean. Make those tasks part of your regular household routine. The anti-tangle design addresses a familiar maintenance problem, but it does not eliminate the need to care for the brush.
