POOL BLASTERSpa Vac Plus Cordless Vacuum for Hot Tubs, Tight Spaces & Small Inflatable Kiddie Pools, Hoseless Handheld Cleaner for Sand, Silt, and Small Debris, by Water Tech

Doesn’t look like much and works great. Cleans out all of the debris from out hot tub.

I followed the directions exactly to avoid previous customer problems to no avail.1) It is nearly impossible to open the vac to empty the debris. You are supposed to "pinch" the general sides, but that does nothing.2) A minor complaint: Due to its shape, it rolls over whenever you set it down. (I don't use the stick long handle.)3) There is no "On & Off" switch. Shockingly, to turn ON the vacuum, one is supposed to partially unscrew the battery compartment hatch lid on the end of the handle which would then make the battery compartment conducive to leaking from that lid if one unscrews the lid a full 1/4 turn to the "On" marked on the handle. Just to test my theory, I did as instructed once, without batteries in it, while submersed in the spa. After carefully drying the outside, sure enough, water had seeped through the lid. After that I only turned the handle barely far enough to just get the vac to turn on (about 1/3 inch). But then later, I observed the battery compartment had additional leaks internally, not just from the battery compartment lid, indicating the whole vacuum is probably leaking everywhere including through the motor.4) You are instructed to completely open all the parts up after each use to let it dry out. I even bothered to dry it with a towel, but rust appeared in the battery compartment immediately anyway.5) The suction seriously diminished while vacuuming probably due to the batteries dying. A set of batteries was destroyed with each use due to leaking.I am convinced, with leaking certainly through the motor too, the vacuum would have only worked a couple more times, but I didn't want to waste any more money on batteries.Remember, if you are going to take the gamble of being upset & buy this anyway, they will not pay for your shipping either direction when it is defective, and be careful to return it within the warranty period to the correct address.

Unit is not high quality. Handle is too light weight. Does not hold onto the vac unit tightly enough. The method used for turning on the power is poorly designed. Requires an extreme amount of force. My wife has to use a pair of pliers to tighten enough to turn it on. Should have been designed with a larger "T" type handle or a waterproof push button switch. Would not purchase again.

Suction power is adequate but not impressive. Quite difficult to squeeze and remove cover in order to clean filter.

I bought this to replace my third grit gitter vac which cost $20 and lasts about a year before it becomes unusable. While searching for a fourth grit gitter I found the SpaVac and decided to give it try. I love it, sure beats squeezing the grit gitter bottle a million times to pick up half the dirt. The SpaVac is no super vac, but does a great job when used slowly. As with any vac you stir up the dirt as you move the vac around. Let the remaining dirt settle and a second pass will get the remainder. It appears to be well built and has a very fine filter to trap the real small stuff. It looks like it will last for a quite a while, but as long as it makes it through the season it will be well worth the money.UPDATE: it stopped working

I recieved this product and had problems with the on/off knob. It was hard to turn and would not turn on in the proper setting. Later it would turn on spontaneously. I talked to the seller and they were really great. They immediately sent another vac. I was delighted when I received the second vac. It works, but once again the knob is so very hard that even my husband has trouble changing knob position. We are considering having a pair of pliers out by the hot tub to be able to operate vac.If the knob issue can be resolved, it would be ideal as it has good suction and once it's on, is easy to use.

I bought this vacuum for my inflatable hot tub. I live in Arizona and we get a lot of dust. It worked great the first time I used it. By the second use, it barely suctioned out anything. By the third use, it was dead. I thought Mayne the batteries had died, so I spent $8 on new C batteries and it worked for about 30 seconds and then completely died. It is a complete waste of money.

works perfect in spa tub - lots of sand, misc. debris. i didn't have a lot of faith that this would work well, so pleasantly surprised. the ONLY thing i despise about this is how the vacuum head gets removed from the debrit receptacle - very hard to open. the large arrows on the vacuum head are irrelevant because it is still difficult to open.
