GRENNIX Robotic Vacuum Cleaner Ground Reviews Summary

Usability

Pros:

• "It is very easy to clean, assemble, and operate."
• "Just drop it in and it will do the rest."
• "It was so easy to use, and was ready right out of the box!"
• "It's very simple as there is not a hose to worry about. It's easy to use. Just charge it up, hold it by the handle and drop it into your pool."
• "It is only 3 pieces total, which is wonderful and makes assembly super easy to clean and take apart."
• "This pool vacuum is simple to use."
• "This is so easy to charge and use."

Cons:

• "I never had a automatic pool vac before, when I got it I was super excited, only to be disappointed, it didn’t work as well as I expected it to."
• "It is not working after one time used."
• "It constantly got stuck in corners and failed to pick up debris effectively."
• "2 problems: weight and material use. because of light weight vacuum is being pushed around by the density of the water, which made cleaning extremely hard."
• "The battery only last 15 minutes or less. If you have any wrinkles in the pool it will not move over them."
• "After 5 minutes of starting to work it shuts down. No power of suction at all."
• "It could have just been mine, however, with that said, it takes 2 hours to charge for just only 1hr of service."

Performance

Pros:

• "Great little helper cleaning the pool. Easy to clean after it’s done and picks up a good bit of debris."
• "Does a good job cleaning up the sediment."
• "This robot vacuum is definitely something to brag about."
• "This vac did great for the price!"
• "Had relatively low expectations however I was blown away with how well this product works. I have an above ground pool and the vacuum makes many passes on a single charge running about an hour completely cleaning all of the debris from my pool."
• "The suction is great and it moves amazing through my above ground pool."
• "This little robot pool vacuum is a beast! Placed it in our 10x16 above ground pool and it went to work."

Cons:

• "I was hoping it would vacuum my pool better but did not work very well."
• "Although it does seem to not have as much suction as I would like for it to pick up."
• "I'll warn against watching it work. It will drive you to drink as its motion is random and it will seem that it will never vacuum everywhere."
• "The vacuum worked 2 times! Rust dropping everywhere!"
• "The suction is not as powerful as I thought."
• "It seemed to have a poor response to obstacle walls and often got stuck in corners."
• "Did not have the suction needed and spend more time trying to get it unstuck from the wall of the pool."

Battery Life

Pros:

• "It comes with charging cord which takes about two hours to charge fully. Which gives it about an hour of operation."
• "The charge last quite a long time, and we do have to empty it after about an hour, but it is full!"
• "The battery actually last for over an hour too."
• "My 10ft round Intex is thoroughly cleaned on one charge."
• "It charges in about 2 hours and is good at picking up leaves on the bottom of the pool."
• "Works fantastic for our 12x22 above-ground pool."
• "We love this vacuum. It leaves the pool floor very clean. Picks up all the debris."
