I got this 10 days ago. The water pump broke at the second use today. I am returning it. Total life: 3 hours.

To be fair, I might just got a defective unit. It performs decently before it died. The suction is strong, although not as strong as I was expecting after reading the reviews. The water tanks are non-detachtable. To some this is a handicap but to me it is an advantage. The detachtable tanks, unless vented upward, will develop leaks sooner or later.

The waste tank has a floating valve that will block air flow at certain water level to prevent water being sucked into the motor. The designer's calculation must be a little off because the shut off occurs when the waste tank is less than half full and the clean water tank still has one third of water left. The tanks are already tiny. This miscalculation means a lot of trips to the water tap if you are washing a big area. Each change of water can wash about 3 feet x 3 feet area one pass. This is quite adequate if you only use it to clean up after accidents or wash upholstery. Washing an average room 2 passes will take 20 or more  trips to the tap, not bad if you have a little extra calories/weight to burn/lose...

As for the water pump, It is a clever design. Air is sucked in from an opening at the bottom and channeled through a turbine that drives a centrofugal pump. It is not the most efficient design but save the need for an extra motor. The bearing/seal between the turbine and the pump is just its plastic casing. It will be just a mater of time that the casing gets worn down the water starts to leak out from the turbine;s air intake. My unit's turbine managed to break free from the axle.
