Review on 💧 Efficient Pool Cover Pump: Submersible Water Sump Pump for Above Ground Pools - Removes Swimming Water with 850 GPH, includes Extra Long Power Cord & 3 Adapters by Shrikant Ojo

Just emptied my (small) inflatable hot tub with this. Worked fine; He drained a 170 gallon hot tub in maybe 30 or 45 minutes. Shipping was incredibly fast (and free with Prime) and it was packaged well. The included "instructions" were pretty much useless, but thankfully not required as it's a fairly basic device. The only thing I wasn't sure about was how much of the device needed to be submerged in water to keep the water flowing through it all the time (to prevent the motor from getting tangled). The jacuzzi was almost empty when the water started splashing instead of flowing, so it seemed to work fine for my needs. You need to be there to keep an eye on it so you know when to turn it off. (Okay - I went back and read the description on Revain; it says it needs a 1cm indentation to work properly.) Nice long power cord. The plastic hose that came with it was quite long.
