Suction Power and Cleaning Performance

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Suction performance determines how effectively this robot vacuum Combo lifts dust, pet hair, and small debris before mop mode starts. In everyday use, the vacuum system pulls loose particles from low-pile carpet and hard floors such as tile and wood, with edge cleaning improving after a few passes. For pet hair, performance depends on the brush roller staying clear, as long hair can interfere with airflow. During the iRobot review, crumbs are handled reliably, but fine grit in deeper seams may require revisiting an area to fully clear it.

Roborock Vexilar W9 Robot Vacuum Cleaner With Mop

The Vexilar W9 review begins with a reported 8000 Pa suction level, designed to lift dust, dirt, pet hair, and debris from carpets, tiles, and hard floors, including particles that sit deeper in carpet fibres. Cleaning performance is shaped by three suction modes: Quiet Mode (50 dB), Standard Mode, and Turbo Mode. For daily pickup on hard floors, the standard setting can be sufficient, while turbo is suited to cases where crumbs cling. For embedded debris, the stronger airflow is aimed at carpet edges and high-traffic areas, although fine dust may still require repeat passes.

Navigation and Mapping

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Navigation and mapping on the robot vacuum focuses on how it plans its route before vacuuming, then switches into mop mode. It scans the space and follows an organised pattern to cover open areas, while adjusting when it meets obstacles such as chair legs or rug edges. With mapping working accurately, fewer missed spots typically occur because it tracks areas it has already cleaned and repeats targeted passes in darker or busier zones. When mapping accuracy is lower, tight corners may be skimmed and manual help may be needed.

Roborock Vexilar W9 Robot Vacuum Cleaner With Mop

Thanks to LiDAR laser navigation, the Roborock Vexilar W9 robot vacuum and mop is designed to follow structured movement patterns around the home rather than running random passes. The manufacturer states it can complete full-home mapping in about 15 minutes. The mapping system is designed with millimetre-level obstacle detection, enabling the cleaner to plan efficient routes and adapt to complex layouts. It can store up to five floor maps, supports room zoning, and includes virtual walls or restricted areas. If areas are poorly defined in the app, it may avoid or miss them.

Battery Life and Run Time

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Battery life on the iRobot depends mostly on which tasks it is carrying out, because vacuuming and mopping use different power levels. Vacuum-first cleaning runs typically last longer than combined cleaning, since mopping increases the load. In practical use, it may handle about 90 - 120 minutes before returning to the dock, then recharge cycles restart. For best results, shorter sessions are preferable on heavy debris, and long uninterrupted mopping should be avoided when floors are large. Battery performance decreases in cold rooms and rebounds once the unit is warm.

Battery performance is linked to how long the W9 can clean before it requires recharging, which is relevant because the robot is designed to cover multiple rooms in one run. This robot vacuum uses 4x 2600mAh batteries, and the manufacturer rates run time up to 150 minutes. Actual time can be shorter with heavy dirt or higher suction modes, but the robot auto-docks under 15% battery. After recharging, it resumes where it stopped, helping maintain coverage across floors. This reduces repeated starts, though very large layouts may still need more than one cycle.

Mop Function

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

The Roomba 105 Combo's mop function is designed to add a controlled wet-cleaning step after the floor is vacuumed, so it can handle everyday dust and light spills in one routine. Users get a tank-based mopping pass that follows the same navigation path. For best results, the owner should fill the mop tank with "Just Water, " and avoid hot water and any water plus vinegar mix to protect performance. On uneven areas, dampness may be lighter, and stubborn stains usually need spot cleaning.

With the W9, the mopping function is built into its 3-in-1 design, so the robot can vacuum, sweep, and mop during the same run rather than needing separate passes. The mop uses a 2-in-1 water tank paired with a dustbin. The W9 provides 3-level water adjustment and 3-level suction adjustment, enabling it to suit different floor types such as ceramic tiles, wooden floors, and marble. It is designed to reduce residual water soaking the floor by controlling suction and humidity. Heavy mess may still require spot cleaning.

Self-Empty and Maintenance

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Self-emptying features can reduce how often the Roomba 105 Combo needs user attention, because debris is moved from the robot into a larger container at the dock after each cleaning run. Robot vacuum self empty helps limit emptying during busy weeks. The dock bin still needs periodic emptying, typically when it fills, and users should check airflow and bin contacts if suction drops. Maintenance also includes cleaning the mop roller and wiper, removing hair from the brush, and rinsing the tank with "Just Water" only, avoiding hot water and vinegar to reduce corrosion and warranty risk.

Once the robot has finished a cleaning run, the W9's maintenance mostly comes down to emptying its dustbin and caring for the water tank used for mopping. For mopping, the 2-in-1 water tank should be refilled or emptied as needed, with mop water kept at appropriate levels, as 3 water settings exist. Brushes and wheels also need periodic checks.

App Control and Smart Features

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Once the user connects the Roomba 105 Combo to Wi-Fi, the robot vacuum app acts as the main control hub for scheduling cleaning, starting jobs remotely, and checking basic status such as run progress and alerts. The iRobot Y311 Roomba 105 robovac review notes that the app supports room-by-room planning and zone cleaning, allowing focus on higher-traffic areas. The iRobot app also provides cleaning mode choices, including vacuum-plus-mop steps, and it provides reminders when filters or mop tasks need attention. Smart features are limited to simple visibility and app commands, with potential delays when the connection is weak, and advanced automation options are not as deep as some competitors.

App control is where the W9's mapping features become practical for day-to-day use, and it complements the maintenance routine that follows each clean. In Amazon UK listings for the Vexilar, the app is used to manage multiple floor maps, with storage for up to 5 floor maps. The app allows rooms to be named, scheduled cleaning times to be set, and cleaning routes to be selected to suit different routines. It also supports virtual barriers and "no-go" zones to help keep sensitive areas protected. For best results, after-clean checks are still needed, as dust and water tank care are manual tasks.

Noise Level

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Noise levels from the robot vacuum Combo are typically moderate for a robot vacuum, but they can vary by floor type and by whether the mop function is running. On hard floors, sound may carry more clearly depending on surface firmness. When the mop runs, additional motor and water-pump activity usually raises noise slightly. For quieter operation, mopping on lower-traffic routes and starting cleaning when rooms are empty can help reduce perceived loudness, though cleaning time may increase.

Noise level matters because it affects how comfortable a home feels during cleaning, particularly around children, pets, or during quieter periods. The robot vacuum offers three suction modes, including a Quiet Mode rated at 50 dB, which is the main reason it can be run during the day. In Standard or Turbo modes, it becomes louder. Reviewers weighing the Vexilar pros and cons should note that Quiet Mode helps reduce disruption, while higher-power cleaning may be less suitable for late-night use.

Pet Hair Performance

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Pet hair pickup is a key strength of the iRobot Combo, particularly on low-to-medium pile carpet and on sealed hard floors, where hair tends to sit on the surface or in shallow fibres. On smooth floors, it gathers fur in a mostly complete pass, though clumps near edges may need a second run. On carpets, it lifts hair effectively, but longer fibres can trap some strands between passes. For buyers weighing the robot vacuum price, performance is best when pet-hair loads are moderate and the brush path is unobstructed.

Roborock Vexilar W9 Robot Vacuum Cleaner With Mop

Pet hair performance is one of the Roborock Vexilar W9's main strengths, supported by 8000Pa suction and cleaning capability for carpets, tiles and hard floors. The robot vacuum for pet hair uses multiple suction modes, including Quiet (50dB), Standard and Turbo, to match power to the task. It can lift embedded pet hair on carpet and pick up debris on hard floors, while LiDAR mapping helps it manoeuvre around obstacles such as under tables and along edges. Results can vary where hair is tangled or very thick.

Cleaning and Maintenance

iRobot Y311 Roomba 105 Combo Robot Vacuum Cleaner With Mop Function

Cleaning and maintenance keep this robot vacuum Combo performing well, particularly because it alternates between vacuuming and mopping modes. After each run, the dust bin should be emptied, hair should be removed from the main brush, and the mop area should be checked for debris. For cleaning and mopping solutions, only authorised solutions should be used, as unauthorised cleaners can void warranty and harm parts. For mopping, the tank should be filled with "Just Water" or an approved cleaner, and hot water and vinegar should be avoided. Filters should be tapped weekly and replaced as needed.

Roborock Vexilar W9 Robot Vacuum Cleaner With Mop

Cleaning and maintenance for the Roborock Vexilar W9 is closely linked to how it handles both vacuuming and mopping, particularly after picking up pet hair. The robot vacuum features an 8000Pa suction system with quiet 50dB, which supports stronger dust removal when carpets and hard floors are configured correctly. After each session, the dustbin needs emptying and the 2-in-1 water tank needs refilling, as consistent airflow and hydration are required for cleaning. For routine care, the app can be used to set suction and the 3-level water output by floor type. After mopping, the surfaces should dry properly before the next vacuum pass.
