Can this be used to clean pool walls and steps in an- above ground pool?
Maureen N on May 27, 2017
BEST ANSWER: Yes just don’t pool out of water when it is on
When do you use the fine debris filter bag?
A shopper on Feb 8, 2019
BEST ANSWER: When there is a lot of dirt on the bottom. I also cut a panty hose inside leg off and put inside the fine filter to catch the dirt and sand so it doesn't go back into pool. Have to dump it more but it works better for catching the dirt.
Can batteries be replaced?
Jerry on Jul 6, 2017
BEST ANSWER: The batteries are not replaceable. You will have to replace the motorbox which will include the battery
does this have its own rechargeable battery unit ?
A shopper on May 25, 2019
BEST ANSWER: Yes; an extension cord is provided to use between AC outlet and vacuum head. While the site says "charges in four hours", most of my charges take only 90 minutes to 2 hours. I have had my unit for almost 2 years, and it is a wonderful addition to my swimming experience, that along with skimmer socks, obviates the need to clean the filter frequently (if at all). My water is crystal clear year-round. I love this product!
Can’t connect charger in vac. Not charging?
A shopper on Apr 29, 2021
BEST ANSWER: It is tricky. I had the same problem when I first got it. It takes a little practice. Look again at the instruction book. I think you have to insert the bottom first and squeeze the sides and fit in onto the “outlet” I have had two - and the second one is for some reason I easier to get on so I’d say if you can’t sit down and figure out how to get it t fully seated and connected; to send it back and try another one. Perhaps there is a small defect....
I hope this is helpful.
I need a replacement filter bag?
Bruce on May 24, 2019
BEST ANSWER: I have never had to replace the bag. You need to clean it after each use. Pretty durable bag.
How well does this do getting the algae from the bottom of the pool?
Jeffery D on Jul 18, 2020
I use the Vac for spot cleanup. If there is algae I would shock the pool with chlorine first and run the filter overnight and then use the F8 to vacuum it clean. The Vac is great and I would recommend it but as I have said I don't use it to do a complete clean. I should mention that I have an inground pool with a vinyl liner (16x32 - 3 to 8ft deep), so it' a large area to clean.
How do you clean the stairs if you have to be deeper than 14.25”?
A shopper on May 6, 2020
BEST ANSWER: I normally just brush my top step and continue downward but I do have to put pole down lower so vacuum still under water. Hope this helps
how do you operate?
A shopper on Jun 20, 2019
BEST ANSWER: It is very easy... make sure it is charged, and filter is on, and I put on pool pole Put in water and turn on and vacuum away. It has awesome power to get even sand out of pool. I highly recommend it
How do you winterize your vacuum?
A shopper on Aug 30, 2017
BEST ANSWER: Also charged it once a month,
Can I purchase an extra charging cord?
LAURA L H on Nov 5, 2020
My Volt isn't working this year. Bought it in May of 2019. It won't turn on after the indicator light turned green. Any ideas what the issie could be?
Laurie B W on May 21, 2020
BEST ANSWER: The exact thing happened to ours (also purchased in May 2019) we had to use the 'warranty' on the vacuum and send it back to WaterTech for repairs (I first contacted Pool Supply about the issue and they were quick to reply and sent me the info I needed to contact WaterTech--I called them to get a claim started). They sent us a new charging unit and it's working again. The only warranty requirement was proof of purchase (with date) and we had to pay to ship it back (which was $40 for us), but we got it back within about 10 days.

Impressed so far!
Once I was able to plug in this unit and charge it, I was impressed with the "suction power" -- it was very strong and swallowed up all of the "mesquite residue" at the bottom of my pool.

At this initial stage, I have noted that:
1. the vacuum is powerful;
2. the "debris cup" is sturdy;
3. two passes around the pool filled the "debris cup" half way with mesquite residue;
4. the unit is easy to assemble and use; and
5. I enjoy most that it's fully self-contained, and doesn't draw the debris into the pool filter.

In conclusion, I have used this unit in tandem with a "pool skimmer sock" and the obligatory 3" chlorine tablets, for the last two weeks, and my pool remains sparkling clean.

I heartily recommend this unit.

Great investment
Friends of our recommended this and I have to say it's a great investment. Very easy to use and cleans our pool within minutes. Holding bag is small but it picks up anything and everything that lays in the bottom of our pool. Love the thicker bag because it picks up sand. We live in SC and have more sand then dirt. Battery holds it's charge, although we haven't used it longer then 45 Minutes, worked great . But would definitely recommend the Water Tech Pool Blaster Volt FX-8Li vacuum. Worth the money.

Simple to use
Purchased June 2017 to use in my inground 8ft round spa. Extremely pleased with my purchase. Powerful motor along with using the fine debris bag easily picks up any fine sand or dirt that has blown through my screen enclosure and settled in the spa. This vacuum is both easy to maneuver and easy to clean.

Great for fine volcanic dirt
I highly recommend this Volt FX 8 U for getting that hard to remove very fine dirt out of one's pool. Although I purchased the sand /silt filter as an extra I use a skimmer basket fine mesh sock in this filter bag for extra fine volcanic silt and it works like a charm and is reusable. The volt definitely is a handy tool especially for around my pool stairs where the silt always seems to settle.

Great pool vacuum
I love this vacuum. Everything goes into a small bag, even silt. It is very easy to use and the charge lasts. The reason I gave it 4 stars is because it is hard to plug in the charger to the unit just right.

Got the job done.
I bought this vacuum after power washing my pool deck. ( I have an in ground pool) A good deal of the poly sand from in between the pavers got into the pool. I was advised not to run our normal pool vacuum since the poly sand could damage the filter. After doing some research I bought the Volt. I’m happy to say it got up all the sand using the finer filter that came with it. Now, the job was very slow and tedious but it got it done. The filter in the Volt filled up quickly so we had to stop quite often to hose it out. And the battery only lasts an hour. But over all, I’m happy with it and I’ll continue to use it for quick clean ups throughout the summer.

Love it. A little hard to make sure you have the charging plug in the vacuum right. Other than that it is great.

Love this pool vac!
We love this pool vac. Had one for a few years and just replaced it. Won’t buy another kind or brand, as long as they keep making this one!
