Roborock Vexilar W9 Robot Vacuum Cleaner With Mop Review UK 2026

Key specifications

Suction Power and Cleaning Performance

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

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

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

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

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

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

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

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

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.

Who Is This Robot Vacuum For?

Who is the Roborock Vexilar W9 robot vacuum best suited for, and what kinds of homes will it fit? It is aimed at people who want automated whole-home coverage, particularly in multi-storey houses, because it maps up to 5 floors and supports 15 no-go zones. It also suits households with mixed flooring, since it can vacuum and mop using a 2-in-1 tank, and it runs for up to 150 minutes before recharging and resuming. Buyers comparing the Vexilar W9 best price UK may also value its quieter operation, with a 50 dB quiet mode.

Where to Buy in the UK

For shoppers in the UK, the next step after weighing the W9's LiDAR mapping, 8000Pa suction, and recharge-and-resume up to 150 minutes is figuring out where it can be bought and what comes with it. In this where to buy in the uk section, buyers typically check the seller's listing for the exact contents. The manufacturer states the package includes a 2-year full warranty and lifetime technical support, plus 24-hour customer service response.
