Water Tank Replacement for Roborock S7 MaxV & Pro Ultra

Replacement Clean and Dirty Water Tanks for Roborock S7 MaxV Ultra and S7 Pro Ultra

Keeping your Roborock S7 MaxV Ultra or S7 Pro Ultra in peak operating condition requires timely maintenance and the occasional replacement of wear-prone components. The clean and dirty water tanks are among the parts that see the most regular use in these self-emptying, self-washing robot vacuum systems, and when they become damaged or degraded, the entire mopping function of the robot can suffer. This replacement water tank accessory set from LDGSUPH provides a direct-fit solution designed to restore your Roborock's mopping capabilities without the need for expensive OEM parts.

What Is Included in the Package

Each order includes two essential components: one clean water tank and one sewage (dirty water) tank. Together, these two tanks form the complete water management system that enables your Roborock S7 MaxV Ultra or S7 Pro Ultra to wet mop floors, rinse its mop pad, and dispose of dirty water automatically. Having both tanks replaced at the same time ensures the entire water circuit is refreshed, preventing issues related to mismatched wear levels between the two components.

Designed for Compatibility with Roborock's Advanced Self-Cleaning Systems

The Roborock S7 MaxV Ultra and S7 Pro Ultra are among the most capable robot vacuums on the market, featuring fully automated self-cleaning base stations that handle mopping, mop washing, and water management without user intervention. The water tanks in these systems are central to that automation. This replacement set is designed to be compatible with those specific models, making installation and integration with the base station straightforward. Users familiar with the original tanks will find the form factor and connection points consistent with what they already know.

Durable Plastic Construction Built to Last

Both tanks are constructed from plastic material, chosen for its lightweight properties and resistance to water degradation over repeated fill and drain cycles. The product name itself emphasizes longevity — these are accessories built to last through the daily demands of an active robot vacuum household. Whether your Roborock runs one cycle per day or multiple cycles, the replacement tanks are designed to hold up under consistent use without cracking, leaking, or warping.

Restore Full Mopping Performance

One of the most common reasons Roborock users experience reduced mopping effectiveness is deterioration of the water tanks over time. Cracks, warping, or mineral buildup can reduce water flow, cause leaks, or compromise the self-cleaning cycle. By replacing both the clean and dirty water tanks simultaneously, you eliminate these potential failure points and give your Roborock S7 MaxV Ultra or S7 Pro Ultra a fresh start. The result is restored mopping suction, consistent water delivery to the mop pad, and reliable dirty water evacuation after each cleaning session.

A Cost-Effective Alternative to OEM Replacement Parts

Official replacement parts from robot vacuum manufacturers can be difficult to find and expensive when available. This compatible replacement tank set offers a practical and affordable alternative for Roborock S7 MaxV Ultra and S7 Pro Ultra owners who need to maintain their machines without breaking their budget. For households that rely on their Roborock daily, having a spare set of water tanks on hand also provides peace of mind — if one set needs cleaning or drying after a deep maintenance session, the backup set can keep the robot running without interruption.

Who Should Consider This Replacement Set

This product is ideal for Roborock S7 MaxV Ultra and S7 Pro Ultra owners whose water tanks have become damaged, cracked, or are no longer performing optimally. It is also a smart purchase for those performing a full preventive maintenance overhaul of their robot vacuum base station. If you notice your Roborock's mop pad is not being adequately wetted, or if dirty water is not being properly removed from the cleaning cycle, replacing the water tanks is a logical and practical first step toward diagnosing and resolving the issue.
