ThAyLa 2-in-1 Water Tank Dust Box for Xiaomi & VIOMI

ThAyLa 2-in-1 Water Tank and Dust Box for Xiaomi and VIOMI Robot Vacuums

Robot vacuums that combine suction and mopping in a single pass are among the most convenient home cleaning tools available today, but they depend on well-maintained components to perform at their best. The ThAyLa 2-in-1 Water Tank Dust Box is a purpose-built replacement accessory designed to restore full mopping and suction capability to compatible Xiaomi and VIOMI robot vacuum models. If your current water tank has cracked, clogged, or simply degraded over time, this replacement unit offers a straightforward path back to optimal performance without requiring a service visit or a costly upgrade to a newer robot.

This accessory is a combined unit that serves two functions simultaneously: it holds the water supply needed for mopping operations while also acting as the dust collection chamber that captures the dry debris vacuumed up during cleaning. This dual-function design is a hallmark of the Xiaomi and VIOMI robot vacuum platform and allows for a compact overall machine footprint without sacrificing either cleaning capability.

Compatibility Overview

Xiaomi Robot Vacuum Mop 2S and 3C

The ThAyLa water tank is designed as a direct replacement for the units found in the Xiaomi Robot Vacuum Mop 2S (model STYTJ02YM) and the Xiaomi Robot Vacuum Mop 3C. These are popular mid-range Xiaomi robot vacuums that combine laser navigation with simultaneous vacuuming and mopping. The 2-in-1 design of the tank is essential to the operation of these robots, and a damaged or degraded tank will directly reduce both mopping coverage and dust collection efficiency.

VIOMI V2 and V3

The VIOMI V2 and V3 robot vacuums use a similar platform to their Xiaomi counterparts and are also covered by this replacement unit. VIOMI models are known for their strong mopping performance and LDS navigation, and keeping the water tank in good condition is essential for consistent water distribution across hard floor surfaces. The ThAyLa replacement is confirmed compatible with both the V2 and V3 variants.

Key Features of the ThAyLa Replacement Tank

Large Capacity Dust and Water Chamber

The combined water tank and dust box is designed with capacity in mind. A larger dust chamber means fewer interruptions to empty the unit mid-clean, allowing the robot to complete longer cleaning cycles without intervention. Similarly, the water reservoir is sized to provide adequate coverage for typical hard floor areas found in apartments and mid-sized homes. The result is a replacement unit that enables the robot vacuum to handle extended cleaning sessions without the frustration of running out of water or filling up with dirt before the job is done.

High-Efficiency Built-In Filter

Included with the water tank replacement is a high-efficiency filter that works within a multi-stage filtration system. This filter captures fine dust particles and microscopic debris as air passes through the dust collection chamber, preventing these particles from being expelled back into the room through the vacuum's exhaust. For households concerned about indoor air quality, particularly those with allergy sufferers or pets, this multi-stage approach to filtration provides meaningful benefits beyond basic debris collection.

Noise Reduction Properties

The water tank module plays an unexpected role in the acoustic performance of robot vacuums. The mass and construction of the tank unit helps dampen the mechanical noise generated by the vacuum motor and cleaning head during operation. Users who run their robot vacuum while family members are sleeping, working from home, or relaxing will appreciate any reduction in operational noise, and the ThAyLa replacement maintains this noise-dampening characteristic of the original component.

Tool-Free Installation

Replacing the water tank on Xiaomi and VIOMI robot vacuums is a straightforward process that requires no tools. The unit slides into position and locks in place using the robot's standard mounting system. ThAyLa designs the replacement to replicate the original component's fit and finish, ensuring a secure, rattle-free installation that maintains the robot's operational integrity.

What Is Included

Each ThAyLa replacement package includes one 2-in-1 water tank dust box unit and one compatible high-efficiency filter. The filter is ready to install from the moment you receive the package, meaning the replacement tank is fully operational right out of the box without needing to source any additional components separately.

Maintenance and Longevity

To extend the life of both the replacement tank and the filter, it is recommended to empty and rinse the dust collection chamber regularly, particularly after sessions in dusty environments. The filter should be tapped clean of loose dust after every few uses and replaced according to the manufacturer's recommended schedule. Keeping the water reservoir clean and free of mineral deposits is also important, particularly in areas with hard tap water. Using filtered or distilled water in the mopping tank can significantly extend the life of both the tank and the robot's internal water distribution components.

Best For

• Xiaomi Robot Vacuum Mop 2S and 3C owners whose original water tank has become damaged, clogged, or cracked
• VIOMI V2 and V3 users looking to restore full vacuuming and mopping capability to their robot
• Households with hard floors that rely on robot mopping for daily floor maintenance
• Anyone seeking an affordable replacement part to extend the useful life of their existing robot vacuum investment
