#14

Reviews highlight separate clean/dirty tanks and automatic refilling of the robot’s internal tank via the dock. Some note tank markings can be unclear, and an optional water hookup kit is...

#15

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...

#16

Water tank capacity and access are praised (large tanks, easy handling on the base), and several reviews note low water consumption per cleaning compared with competitors.

#17

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

#18

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...

#19

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...

#20

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...

#21

Water handling is positive, with reviewers noting smooth tank removal and automated clean-water management.

#22

Large clean/dirty water tanks are a recurring plus for longer intervals between refills/emptying, though you still need to swap water on a regular schedule.

#23

Large clean and dirty water tanks reduce refill frequency for many homes, but you still need to empty dirty water regularly to avoid odors. Real-world cadence varies by home size,...

#24

The clean/dirty water tank system is generally seen as easy to manage, with well-designed tanks and clear separation of dirty water. A common tradeoff is capacity: at least one review...

#25

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

#26

The system uses separate clean and dirty water tanks and is often described as low-effort day to day, but it still requires periodic refills and emptying. At least one reviewer...

#27

Water tanks on the dock are easy to access and support regular mopping, but you still need to refill clean water and dump dirty water. Some guidance suggests emptying dirty...

#28

The water tank system was well received for its easy handling and impressive capacity relative to the compact base.

#29

The onboard water tank is described as generous for this class (roughly mid-300 ml), which helps in apartments, but there is no dock refilling so large homes may need refills...

#30

The water-tank score is positive where reviewers praised the station’s automated water refilling and maintenance workflow.

#31

Water-tank maintenance was manageable in one review, with about weekly changes during daily cleaning.

#32

The dual-tank dock system is praised for making mopping more hands-free, though refill/empty frequency varies and some reviewers note fill lines or tank access could be clearer.

#33

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

#34

Dual clean/dirty tank design and onboard dirty-water handling help the roller stay fresh; some early units reportedly had dirty-water tank leakage issues that were later corrected.

#35

The clean/dirty tank setup is commonly described as easy to use, but there are tradeoffs: some miss transparent or externally visible tanks, some describe smaller/hidden tanks requiring more frequent refills,...

#36

The system relies on clean and dirty water tanks in the dock and an internal water tank in the robot, which keeps mopping more automated than vacuum-only robots. Expect periodic...

#37

The water tank was considered workable and easy enough to handle, though one tester noted capacity was slightly below average and another emphasized the need to swap/fill it.

#38

Water-tank feedback was limited but positive, with the transparent fresh-water tank treated as a practical advantage for checking levels.

#39

Clean/dirty tank capacity is adequate for typical homes, but heavy mopping or daily runs can require weekly (or more frequent) refills/empties depending on area and settings.

#40

Water tank capacity and handling are generally viewed as adequate for routine mopping and occasional spot cleaning, but extended deep-clean use can drain a tank quickly. Shared tank design is...

#41

Clean/dirty water tank system works well but can be water-hungry on frequent cleaning—some users report refills every 1–3 days depending on home size and settings.

#42

The clean/dirty tanks are convenient and easy to remove, but capacity is on the smaller side, meaning more frequent refills/empties in larger or high-mop-use homes.

#43

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...

#44

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

The water tank and water delivery are described as basic but usable for light mopping; expect maintenance and refills, especially for larger areas.

#48

The water tank is small (often 145mL; one related model cites a larger tank), with adjustable water flow. Large hard-floor areas may require refills.

#49

Large dock tanks support hands-off cleaning, but the system is water-hungry due to frequent mop-pad washing and no onboard water tank on the robot.

#50

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