Best Roborock Robotic Vacuums for Water tank

#1

Reviews consistently mention separate clean/dirty water tanks plus onboard water handling that keeps pads wet. Tank refills/empties are a routine task, but capacity and adjustable water use are generally seen...

#2

The clean/dirty water tank setup is a key convenience feature; reviewers cite large tanks (around 4 L clean and ~3.5 L dirty in one real-home test) and automatic onboard refills....

#3

The water tank and flow controls were praised for size and sophistication, especially for frequent mopping.

#4

Large clean/dirty tanks (often 4L) enable hands‑off mopping; robot tank is small but auto-refilled; some docks can be plumbed.

#5

The dock’s clean/dirty water tanks are large in reviews (commonly 4–5L), enabling hands-off mopping for long stretches, though you still need to empty dirty water and refill clean water periodically.

#6

Water tank capacity and the clean/dirty tank system are repeatedly described as generous and convenient, enabling multiple cleans before intervention. Users still need to refill/empty on a cadence based on...

#7

The water tank was viewed positively for its relatively large size and ability to cover a meaningful area before running low.

#8

Clean/dirty tank capacity and usage rate are viewed as competitive; some comparisons suggest it can go longer between water changes than many rivals, though frequency still depends on home size...

#9

The clean/dirty water tank system is frequently described as convenient, with reviewers citing generous capacities (for example, 4 L clean and 3 L dirty in one review) and automatic refilling...

#10

The clean/dirty tank setup is considered convenient and easy to remove, and the robot also carries an onboard water tank that gets refilled at the dock. Multiple reviews warn the...

#11

Large dock tanks reduce refill frequency in some homes, but dirty-water emptying can be frequent if you mop often.

#12

Water tank feedback was mostly positive for ease of use, but the small onboard dirty-water tank requires cleaning after mopping.

#13

The water tank approach works for routine wet cleaning, but several reviewers want an official cleaning-solution option and note tank capacity/cloth management can limit larger jobs. Users who pre-wet or...

#14

Water-tank feedback was mixed: tanks were easy to reach, but the dirty-water tank still needed regular cleaning.

#15

Water-tank feedback is mixed: tanks are easy and efficient, but missing fill lines and ongoing refills remain caveats.

#16

Water tanks were easy to handle in some reviews, but others found them awkward or in need of frequent refilling.

#17

Water-tank feedback was mixed: one reviewer found frequent refilling bothersome, while another framed occasional filling and emptying as simple.

#18

The onboard water tank is commonly described as small, limiting mopping coverage per fill. This pushes users toward room-by-room scheduling or more frequent refills for larger spaces.

#19

Water tank evidence is negative from CNET, which called the tank too small despite the dock's refill system.
