5.0 out of 5 stars
Love the simplicity, July 17, 2009
This review is from: Aquabot ABTTJET Turbo T Jet Robotic In-Ground Pool Cleaner (Lawn & Patio)
With so many things to maintain for a pool already, the last thing I want to do is to maintain an automatic pool cleaner. If I have to replace belts, tracks, booster pumps, and so on, then I might as well spend that time with an old fashioned pole vacuum instead. Before I bought this T-Jet I had a tough time deciding between the Polaris series, T-Jet, and the Turbo T2 model.
I ended up buying the T-Jet because of the simplicity with so few moving parts that can break. I'm happy with the decision. The T-Jet cleans the pool crystal clear. But to get the best performance, first I had to make some adjustments to the setup out of the box. So here are some tips.
The settings on the T-Jet when it first arrives are for impressing you with the speed in which the water jets propel it across the pool - to maximize the water flow but not maximizing the cleaning potential. The changes I made were the following: 1. snap on the intake extender so that the suction port is closer to the pool surface, 2. slide the internal tab to narrow the intake slightly for more suction power, and 3. add two of the foam squares to the inside for more neutral bouyancy.
By increasing the bouyancy with the included foam pieces, the T-Jet more easily jets up the curve from deep to shallow. I also found that by increasing the lap time from 30s to 40-60s (max 90s) this gives it enough time to make the length of the pool (rather than just the width) before it reverses direction.
I read one review where someone said their T-Jet flipped upside down sometimes. I don't understand that because what I observed is that even when I push it around with my hand it wants to stay upright, and the floating power cord keeps vertical tension on it to keep it oriented correctly. I think that must have been user error.
Lately I just drop it in the pool once every few days and let it run all day long, or overnight. I was surprised how much dirt gets collected in the fine filter bag because the pool already looked clean but the filtering is really effective. I can run the main pump less so the DE filter doesn't have to work as much; I noticed that the PSI gauge doesn't increase as fast when I use the T-Jet. So it saves on electricity, since the T-Jet uses a fraction of the electricity as the main pump.
The only negative I found (and this is pretty minor compared to all the positives) is that the cord tends to get twisted up if I leave it in the pool for several days in a row. I have to remove it anyway to rinse out the filter bag. Then I untwist the cord.
I am happy that I bought this instead of the Turbo T2. I don't think the track models like the Turbo T2 can do anything better than this one, at least for my pool. I think those just have more moving parts to maintain.
Update 1/9/2010: I found out why people report sometimes that it stops climbing the wall. Those user-replaceable foam buoyancy squares on the bottom plate soak up water and wear out over time. Just replace them or add some more, takes 10 minutes. When mine wouldn't climb the wall as high anymore I inserted some more styrofoam squares from a shipping box. Now it climbs all the way up again. With this pool cleaner it is important to maintain the neutral buoyancy.

Almost Perfect, June 21, 2009
This review is from: Aquabot ABTTJET Turbo T Jet Robotic In-Ground Pool Cleaner (Lawn & Patio)
**Update: After a year of use, I'd still give it a 4 star rating. Over the past year, I never had to clean the filter cartridges on my pool. All the dirt and debris that usually went into the filter cartridges got vacuumed up by the robot. I also never had to vacuum the pool using a vacuum head connected to by pool's filtration system. This spring my pool was a mess with dirt and leaf debris. I put in the robot with the leaf bag and several hours later all the debris was vacuumed up. Then I switched to the fine filter bag and a few hours later had a pristine looking pool again. For the money, this has been a great purchase. **
Before I bought the turbo, I was cleaning my pool using a conventional vacuum head on a pole that was connected to my filter system. It would take me at least 30 minutes to move the vacuum back and forth across the entire pool to clean it. I have a cartridge filter system so all that dirt I vacuumed up just went into the filter. At times I would have to clean the filters every 4 - 6 weeks if we had a lot of dust blow into the pool. So I finally decided to get a robot to do the cleaning. The great thing about the robot is that it is not connected to my filter system so I don't need to clean the filters as often.
The robot does climb and clean the walls, but not all the time. It also is not computer controlled so it does not learn your pool. One axle on the robot pivots and is locked in place with a pin. As it moves around and runs into a wall, the axle will pivot so the robot follows a different path when it reverses direction. I have a 15' x 30' pool. After about 2 hours, it has cleaned at least 90% of the pool. Some times I will use a pole to give the robot a little nudge to steer it to areas it has missed. It does not do stairs at all so I always brush the stairs first.
Overall I am happy with the robot, especially for the price. A true computer controlled robot will cost almost $1000 and has many parts that wear out. Several pool supply shops have told me that the treads on those robots need to be changed every year. The only thing that will probably wear out on the turbo t-jet is the filter bag. I also like how much dirt it picks up. Sometimes the pool looks very clean, but I will put it in anyway. After 2 hours the filter bag has a lot of dirt in it. So it does vacuum very well. And that's all dirt that would have ended up in my filter cartridge at some point.
So overall, 4 stars because it does a good job. I'd give it 5 stars if it truly cleaned the entire pool with no intervention from me.

Disappointing performance on algae, September 26, 2009
This review is from: Aquabot ABTTJET Turbo T Jet Robotic In-Ground Pool Cleaner (Lawn & Patio)
I purchased the Turbo T Jet primarily to help deal with occasional heavy algae build-up in my in-ground, kidney-shaped pool. Using the fine cloth filter bag the robot does clean up algae from the bottom of the pool, but within 20-30 minutes it stops in its tracks due to loss of suction caused by the collected algae. It takes about five minutes to remove the robot from the pool, clean out the filter bag, reassemble it, and restart the program. I have to do this 3-5 times before the majority of the pool has been cleaned. What I had really hoped for for was something that I could "set and forget". No such luck, unfortunately, at least not with heavy algae. When the pool has just a light amount of algae (i.e., barely visible) the robot will run for 90 minutes or so before it has to be cleaned.
The other drawback is that it does not do a very good job of covering the full pool area -- possibly because of the irregular shape of my pool. I watched it for 10 minutes today as it went back and forth over the same swath; I eventually had to pull it to another area of the pool to get it out of that mode.
Pros:
* Has a variety of controls for changing amount of suction, floatation, type of filtering, and amount of time between direction reversals
* Simple design
* For leaves and larger debris seems to do well
* Picks up algae effectively until it clogs
Cons:
* When cleaning heavy algae build-up, robot clogs up quickly. May have to remove and clean filter bag multiple times before pool is cleaned.
* Does not clean pool sides very well
* Does not have very good coverage with kidney-shaped pools
* The control panel has an interface that only an engineer would love
Bottom line:
For me, it requires too much intervention to be considered a truly useful tool.
