I gotta say, I'm impressed with this little monster. I've had it just over a week now and used it several times to clean my 16' x 32' rectangular pool. The pool is 3' deep at both ends and 5' deep in the middle, making the slope well within the specified 15 degree limit. My wife named the little guy Herbie, because he looks like the Love Bug from the movie.About the performance: my pool litter is mainly comprised of ash tree leaves, pine needles and fine desert dust. This robot picks it all up, no problem. I've always owned pressure-side cleaners from Ray Vac to Polaris 360. This robot cleans at least as well as they did within its 90 minute cycle. It helps if I use the pole brush to push the silt out of the corners of the pool before it runs, as when the Paxcess gets to the radius at the base of the walls its suction gates are sometimes raised too far from the plaster to pick up everything. But I can't say for sure that it wouldn't eventually scatter the dust and pick it up. I need to try without the brushing to know for sure. But as for leaves and pine needles on the floor of the pool, they're all gone within 90 minutes.What Paxcess doesn't do: It doesn't climb walls, more than just the radius at the base. It also won't get onto steps or ledges. It doesn't brush the surface. It has a single, stationary, brush that's used to help it pick up debris, not to scrub the surface. It doesn't have intelligence to map the pool, its movements are guided by the directional settings you set on its two jets, and it will take some experimentation to get them set right to cover the entire pool. Mine was spending 90% of its time in one half of my pool until I spent an hour or so watching it and fiddling with settings on the jets.. not unlike the pressure-side cleaners I've owned. But once dialed in, it covers every part of the pool. It doesn't stay in the pool and run in the background or on a timer. When you need the pool cleaned, you turn it on, drop it in and let it run, then pull it out after 90 minutes (it stops near the side of the pool where you can grab its string/handle, but sometimes I need to use a pole to reach it, no big issue). Then hose it out and put it back on the charger. It will be ready to go again in about 4 hours.At about half the price of a pressure-side cleaner and about a third the cost of a plug-in robotic cleaner, I think this performs at least as well as the former, and probably nearly as good as the latter, if you don't mind starting and stopping it each time. And cleaning it out is easy. Other reviewers have included photos of the screen and holding area. Both are the size of the entire chassis of the unit, so there is plenty of screen and capacity.As with all rechargeable things, I'm sure the battery will degrade over time, and I'm hopeful that replacement batteries will be available (maybe they already are, I haven't looked). But overall for the price, and if you don't mind manually brushing the walls and steps once in a while, this is a great cleaner. I'm very satisfied with my purchase.I have a 10,000 gallon kidney shaped pool. Shallow side is 3.5 feet deep. Deep side is 6 feet deep. The bottom isn't flat and it curves up on the sides from bottom to top.I'm experienced with maintaining a pool. I have a System 3 diatomaceous earth filter that has 53 sq ft of filter space. Run the pump 12 hours a day at 2200rpm to achieve balance between energy usage and turning the pool over (happens about every 3 hours according to the math).I loath hauling out my pole, sweeper, filter canister, and connecting all of this to the pump via the skimmer to vacuum the floor and sides of my pool. Take too long, too many nuances. Been doing it this way for decades. I figured technology could make it easier for me. Aside - I don't use an auto vacuum since I have dogs that swim all the time. Don't want them to catch a hose and drown.The main things that litter my floor are dog hair, sand / crushed granite from nearby paths, material from the roof of my house, leaves from many trees, and DE powder from when I spray the filters after vacuuming (backs out thru the line).I grew up swimming in creeks so having a perfectly clean pool isn't my goal. I just know I need to clean it from time to time in order to keep algae from forming. In general, I keep my DE filter clean by back washing once a month, I vacuum the floor about once a month, and I skim weekly.I finally decided to try one of the automated, cordless vacuums. These are the ones I tried.POOL BLASTER Max CG, $299https://www.amazon.com/dp/B002L61OGAPaxcess Cordless Robotic Cleaner, $318.09https://www.amazon.com/dp/B088JWRWGMAIPER Cordless Automatic Pool Cleaner, $876.81https://www.amazon.com/dp/B09KY211BPWinner was the Pool Blaster.Paxess- Filter screen is about 180µm which wasn't able to catch all the DE (DE is generally less than 100µm in size). The unit blew much of the DE back into the water. It did filter some.- Wasn't strong enough to climb up from my deep end so it remained in the deep end.- I felt the Paxess performed better than the Aiper in my pool. Might not for yours.- Charging was easy. Battery worked fine. Lasted about an hour.Aiper- Filter screen was much too big. Couldn't catch DE nor sand. Manufacturer didn't disclose size of filter. Blew debris right back into pool.- Unit claims to climb up walls. Mine didn't. It would attempt to climb it, back flip, then try again...over and over as it worked around the pool. Very odd behavior.- Charging was easy. Battery worked fine. Lasted about an hour.Pool Blaster Max CG- I really like this tool. It's different than the robots. It's a self contained, battery operated, cordless device. But, you attach it to the end of your pole.- I'm used to using a pole to work on my pool and I like the exercise of using my legs, arms, and core.- So, this tool really spoke to me.- Comes with 2 filters: one for general debris and one for super fine stuff like DE. The DE one is excellent! It captured all of my DE. However, I had to empty it after every length of the pool (short length of about 6 feet). I had to empty it about 30 times in order to clean all the DE off the entire bottom of my pool. This sucked (<-- pun)- So, I modified my approach. I turned up my pool motor to max RPM and scrubbed the pool to get the DE in solution. Then the next day I vacuumed with the general filter. This seemed to greatly help but it wasn't perfect.- So, I reset my expectations and my process. The next time I sprayed the filters in my DE bubble, I emptied the bubble into my sewer line of my house (very easy and fast for me to do). I don't run backwash / pool water waste to my yard because the chlorinated water damages my trees and vegetation. Then, I capped my line that goes back to my pool. Spray quickly. Then reassemble and I'm done.- Now, when I use the Pool Blaster, I can use the general filter basket and I can vacuum the whole pool in 30 min. Doing it the old way with the hose, vacuum head, canister, etc used to take 2 hours because of how many times I had to stop and tend to the nuances. I also had to backwash / clean the filters in the DE bubble to avoid algae building up in the bubble- Emptying the filter of the pool blaster is super fast. Take me less than 2 min. I shake it out into a bucket, then I rub it while dunking it into the skimmer. Then back to work.Suggestion to Pool BlasterIf they had a filter that was in between the size of the fine one and the general one, it'd be even better.Overall, I'm happy with the Pool Blaster.I'm happy that the time to done is 30 min vs 2 hours. And, I don't have to clean my DE filter after vacuuming the pool to avoid algae building up in the DE canister. The Pool Blaster is a completely separate tool which means my DE filter remains untouched and hence I don't have to clean it every time. We live in a hot, humid environment so fighting algae is always a thing.UPDATE: updating my review from two days ago…. We had an issue with the turn dial where it was stuck on “off” and we could not turn the vacuum “on”. We added a little WD-40 to the dial and it is back to working. Upgrading my review to 4 stars because the vacuum does clean up the floor of the pool very well. I am worried that the dial will malfunction again, but if it does, now I know what to do.I had this product delivered on 8/20/2022. Today is 10/16/2022 as I write this review. Used the pool vacuum 4-6 times over the past two months. Now, when I try to turn the dial from “Off” to “On”, the dial is stuck and will not turn. It is stuck on the “Off” setting, rendering this product useless. I hate writing bad reviews, but this just feels like a complete waste of money right now. Hoping it can be fixed, and if it is, I will update my review.Quería una aspiradora automática para mi pequeña alberca y había visto unas buenas opiniones sobre este modelo, Oh gran error. En primer lugar, sólo funciona para partículas grandes, eso lo aspira bien, pero si quieres aspirar ese polvo fino que se asienta después de echar el clarificador o algicida al agua, olvídate de esta aspiradora, ya que lo único que hará será aspirarlo para volverlo aventar, quedando toda el agua turbia de nuevo hasta q el polvo se vuelve a asentar. Además, si el agua donde vives tiene muchos minerales o es "dura", olvídate también, esta aspiradora tiene unos conectores metálicos que es donde embona la punta del cargador para recargarla, y con los minerales en el agua se le hacen verdes y se llenan de sedimentos minerales (esto sólo después de un sólo uso), y como pueden ver en la imagen, en el cuarto uso, uno de esos conectores simplemente se cayó, ni siquiera supe cómo xq así la saqué de la alberca. He escrito a la garantía (xq la ventana de devolución ya había cerrado) y no he obtenido ninguna respuesta después de exponer mi problema. Así que háganse un favor, ahórrense problemas y dinero y no compren esto.We did everything wrong - we charged it in the ON position and we turned it ON - BECORE we put it in the water - the 2 things you ate Not Supposed to do- it still worked to our relief we did not ruin itIt takes about 4-5 hrs to charge and runs happily for 2-3 hrs in the pool. By turning each of the dials on the ends you can vary the back up turn circle of the robot and we generally get a pretty good clean radius of the pool in 2 cleaning cycles. We don’t have many trees but we had a deck built so the pool got dirty. This is a reliable little robot and worth the $.It’s good for picking up sticks, bugs and rocks and harder type debris. We lasted for months just using the robot waiting for our filtering system to be installed without too much distress until the last hot week of the summer.I would buy it again for sure.Took too long to clean the pool had to charge and re-charging takes 6 hours! Also this unit did not clean the whole pool as promised, even after adjusting the settings many different ways; the cover for the charging prongs is not tight enough therefore it corroded and now is rendered unusable and one of the prongs even fell off! Poor design and poor service (non-existent) will never purchase an expensive item again from Amazon.El PAXCESS no es muy robusto y la garantía es muy basica:el PAXCESS limpiador no funcionó despues de 2 meses. Y sigue no funcionandoLa garantia es basica:1. hicieron auto evaluación por email y photo del problema :2. me mandaron una pieza que instalamos.3. Pero el limpiador sigue no funcionando porque están por mandar un cargador que nunca llego.Entonces cuidado con este producto que es muy caro pero no muy robusto con una garantia parcial y muy básicaEs lo mejor cosa que compre para limpiar mi alberca.Es increible como es facil y rapido a limpiar. No necesito los mangueras y todo para limpiar, ahorita solamente le dejo en mi alberca y 1 hora y media esta lista. Tiene que cargar por casi 5 horas cada vez y dura 1 hora y media por limpiar pero esta una cosa excelente para mi alberca!!
