iRobot G185 Roomba 405 Combo + AutoWash Dock Robot Vacuum Cleaner Review UK 2026
Quick verdict
Score: 6.6/10
Best for: Homes wanting hands-off floor cleaning on hard floors and carpet, with mopping and self-empty dock
Not for: Homes with lots of floor clutter, cables or deep high-pile carpet, where a robot struggles
Bottom line: A robot vacuum (vacuum + mop, self-empty), a capable hands-off cleaner with LiDAR laser navigation for everyday floor upkeep.
Sometimes, a "combo" robot vacuum-mop setup like the iRobot G185 Roomba 405 with the AutoWash dock makes sense because it can switch tasks, though the dock handles cleaning of the mopping system. The quick verdict is mixed. For day-to-day floors, it offers practical mopping cycles, and vacuum runs can follow without user resets. However, cleaning results depend on using the right approved solution, and using unauthorised liquids may risk warranty issues. It also needs careful water-only setup, with no hot water, to avoid reliability issues.

Suction Power and Cleaning Performance
Suction power and cleaning performance determine how well this robot vacuum Combo lifts dust before it switches to mopping, and this matters most on carpets, edges and high-traffic lanes. In typical use, this model pulls loose debris well from low pile carpets and collects more grit along baseboards when furniture is kept slightly spaced. Corners may need a second pass because brushes and suction can miss compacted dust, particularly on thick rugs. After vacuuming, the mopping phase runs with less airborne debris, but mopping results depend on drying time.
Navigation and Mapping
Navigation in the iRobot Combo relies on onboard sensors and a planned cleaning pattern to move through rooms efficiently, switching from vacuuming to mopping once it reaches the mapped area. The robot scans walls and obstacles, then charts a route that prioritises coverage over random passes. Users may see it clean in neat lines as it repositions around furniture legs and cables. Mapping accuracy can drop in cluttered, highly reflective, or very dark spaces, since sensor readings drive updates.
Battery Life and Run Time
Battery life on the robot vacuum with AutoWash dock is typically sufficient for cleaning a small-to-medium home in a single session, as the robot can vacuum and then switch to mopping after it reaches the mapped zones. With the AutoWash dock, a standard cycle often completes in one go where floors are mostly open. In cluttered rooms, runtime can be reduced due to more obstacles and slower navigation. When the battery charge drops, the robot returns to the AutoWash dock to recharge and refresh. For larger areas, repeat passes may be needed, particularly around thick rugs and in tighter corners.
Mop Function
After the vacuum phase finishes and the robot returns to its mapped cleaning zones, the Mop Function begins wet-cleaning by switching from vacuuming to mopping. The AutoWash dock refills and refreshes the system, dispensing the approved concentrate and topping up clean water depending on the selected solution. Using the same mapping, the robot moves in steady passes over hard floors. Expect improved pickup of light stains, although results vary with grout depth and sticky residue. For warranty safety, only authorised cleaning solutions should be used, and hot water should be avoided.
Self-Empty and Maintenance
Once the self-empty cycle finishes, routine care becomes the priority for both the robot vacuum and the AutoWash dock, because clean parts help maintain suction and prevent odour build-up. A robot vacuum self-empty workflow reduces how often emptying is required, but filters still need checks, and the dock waste bin must be kept dry. Inspect the bin area weekly, wipe the sensor windows with a dry cloth, and check the brushes for hair tangles. The AutoWash dock also needs periodic rinses, and any cleaning solution must follow the approved instructions, since unauthorised products may corrode parts and void warranty.
App Control and Smart Features
App control and smart features allow owners to manage the Roomba and the AutoWash dock from a phone via the iRobot's companion app. The app supports scheduling, start or stop commands, and status checks including battery level and cleaning progress, as well as monitoring dock wash activity. It also issues alerts when filters need attention. Setup can take several minutes during initial pairing, and smart features depend on Wi-Fi stability.
Noise Level
Noise levels from the robot vacuum with AutoWash Dock are usually noticeable, but they are typically not extreme for a home robot vacuum. In everyday use, it produces a steady operating hum, plus brush and dock sounds during charging. It runs more quietly on open floors, with noise rising slightly when it bumps into edges or changes direction. During AutoWash dock cycles, the unit can sound louder for a short time, so scheduling those cycles can help if the robot is left to run while you are in another room.
Pet Hair Performance
Pet hair performance on the iRobot G185 Roomba 405 with AutoWash Dock is commonly best on hard, open areas, because the main brush and suction can lift loose fur before it mats into carpet fibres. With the iRobot uk, pet hair tends to collect quickly along edges, where the side movement helps sweep it inward. As a robot vacuum for pet hair, it handles light shedding well on low-pile rugs, but deeper carpet can hold onto hair, requiring more passes and wider coverage. Overall, results improve when pets shed frequently, yet stubborn clumps remain a weak spot.
Cleaning and Maintenance
Cleaning and maintenance help the robot vacuum with AutoWash Dock work well over time, particularly when it is used on mixed floors and clears everyday debris daily. Routine care keeps airflow steady: empty the bin when full, rinse the filter when needed, and wipe the sensors with a dry cloth. For the dock area, the dock tank should be filled only with approved products. The recommended approach is to use "Just Water" with no hot water or vinegar, and to follow the stated cap or pour amounts.

Frequently Asked Questions
Is this robot vacuum worth it?
A robot vacuum like the iRobot earns its place for day-to-day floor upkeep, freeing you from routine vacuuming and damp-mopping hard floors. Its self-empty dock means weeks between bag changes. It handles upkeep rather than deep cleans - check the current Amazon UK price, as it changes often.
Can the robot vacuum mop as well as vacuum?
Yes - the iRobot vacuums and damp-mops hard floors in one run. Mopping suits sealed hard floors, not carpet, and is best for light daily marks rather than stuck-on stains.
What are the downsides of the robot vacuum?
Robot vacuums struggle with floor clutter, loose cables and deep high-pile carpet, and the brushes, filter and sensors need regular cleaning. They are for routine upkeep, not a replacement for an occasional deep clean.
Is the iRobot G185 Roomba 405 good for pet hair?
This robot vacuum is designed to lift pet hair from hard floors and low-pile carpet; long-haired pets may still need a periodic brush clean to clear tangles.
Does the iRobot empty itself?
Yes - the robot vacuum comes with a self-empty dock, so the onboard bin is emptied automatically and you only deal with the larger base bag every few weeks.
How does the iRobot navigate?
The robot vacuum uses LiDAR laser navigation to map rooms and plan an efficient path, rather than bouncing around at random.
How long does this robot vacuum run on a charge?
It runs for up to 120 minutes per charge, then resumes after recharging on longer cleans. Real run-time depends on suction level and floor type.
Does the iRobot G185 Roomba 405 work on both carpet and hard floors?
Yes - it moves between hard floors and low-to-medium carpet automatically, though mopping is for hard floors only. Deep or high-pile carpet is the main limitation for any robot vacuum.
