🔌Will it get stuck on cords or run over pet poop?
Camera-based avoidance is the fix. On Vacuum Wars’ 24-object course, results ranged from a perfect 24 down to fewer than 10, and the camera-equipped flagships sat at the top. Hide loose cords anyway; it’s the cheapest insurance there is.

🐕Will dog hair, or mine, wrap around the brush?
Look for two scores, not one: pickup and tangles. The Dreame L60 Pro Ultra and Ecovacs T90 Pro Omni both finished Vacuum Wars’ 7-inch hair test with nothing wrapped.
Our pick for this: Dreame L60 Pro Ultra
💧Will the mop soak my rugs?
Check how far the mop lifts and whether it can come off. The T90 Pro Omni raises its roller 0.6 inches on carpet, the X12S also closes a cover over it, and the L60 Pro Ultra can leave its pads in the dock.

🛋️Will it fit under my sofa and bed?
Measure the lowest gap first. The X60 Max is 3.13 inches tall; Vacuum Wars measured the Roomba 105 at 4.1 inches, which rules it out of a lot of living rooms.

🚪Can it get over the threshold between rooms?
Ordinary saddles are fine for most robots. For tall ones, trust tested climbing over box claims: Vacuum Wars saw both the X60 Max and the L60 Pro Ultra clear 51 mm.

💸What will bags, brushes and filters cost me?
In the listings we checked on October 24, 2026, brush-and-filter kits for these robots ran about $17 to $30, and a six-pack of dock bags about $10. Bagless docks drop the bag line entirely.
Fix: Estimate your yearly upkeep
🏢What if the company goes under?
It already happened to iRobot: Chapter 11 in December 2025, then a sale to its contract manufacturer, Picea, in January 2026. iRobot says apps and support continue, but favor brands that still ship app updates and sell parts.
Fix: What it means for Roomba owners
📱Do I have to use an app?
Once, for setup. Mapping, room cleaning and schedules live in the app, but after that most people rarely open it: set a schedule, link Alexa or Google, and use the robot’s own buttons. Most robots here set up on 2.4 GHz Wi-Fi only.
📷Is a robot with cameras a privacy risk?
Treat it like any camera in your home. Dreame’s app, for example, includes privacy settings for its camera models. Turn off remote video if you don’t use it, keep firmware updated, and put smart devices on a guest network if your router offers one.
🔊Is it loud enough to bother me?
The robot runs at a steady hum; eufy, for example, rates the E25 at 61 dB or less even on max suction. The loud part is the dock’s self-empty, a strong burst that lasts a few seconds after each run, so schedule cleaning for when you’re out.
Our pick for this: eufy E25
🏠Will it handle a big or two-story home?
Size mostly changes how long a clean takes. Vacuum Wars measured the X60 Max covering about 950 square feet per charge, and robots recharge and resume where they stopped. For a second floor, choose a robot that saves several maps (the eufy E25 keeps five) and carry it up, or buy a second robot.
Our pick for this: Dreame X60 Max
🧹Will I still need a regular vacuum?
Yes, for stairs, sofa cushions and the occasional deep clean. Consumer Reports notes that uprights and canisters still deep-clean carpet better, so the robot handles the daily dust and a light stick or handheld covers the rest.
Fix: A handheld for the stairs
Where these questions come from: the searches people actually type about robot vacuums (“robot vacuum for pet hair”, “shark robot vacuum troubleshooting”), the failure points independent testers measure (obstacles, hair tangles, thresholds, mop lift) and the problems long-term home tests turned up.
