picks up standard debris.
Doesn't do steps, but most won't anyway.
Doesn't clean fine particles
Lightweight easy use. upgraded to a dolphin x30 very happy now
Good for price point hough. thanks

Positives:
- The OT15 does the basics of what it should do. It vacuums the bottom of the pool and scrubs the walls.
- It is easy to empty and clean.
- It is easy to operate
Negatives:
- It isn't particularly great at wall climbing a lot of the time
- It doesn't deal well at all with anything too thick on the bottom of the pool. Don't expect to be able to throw it in if your pool is fairly messy - you will need to scrub and vacuum first
- It doesn't deal well with fine dust. Where I live there is a LOT of fine dust.

We have owned the Zodiac OT15 pool cleaner now for just over a year. We bought a robotic cleaner because suction cleaning was not effective especially if the filters were not clean. Manual cleaning also was a pain especially in the middle of summer. The good points about the OT15 is that it will run for about two hours and clean the pool. However, it does not clean the pool 100%. Its logic is meant to clean the entire pool from the entire pool floor and sides but from watching it, it seems to miss alot of the pool floor. At a guess, it cleans a...

Had it since August and I've been constantly disappointed with its performance.

It isn't able to clean rounded corners so you'll need to use a broom to move dirt to the middle of the pool before running, it doesn't have a swivel on the cable so the cord needs to be untangled every-time you run it and it has no intelligence / learning whatsoever.

From observation, it seems to have a fixed 3 step program:
1: Go forward until it climbs above the waterline for a few seconds.
2: Reverse for a few seconds then stop and wait to settle on the floor
3: Reverse for a fixed time then start again

It's just really hopeless and I'd recommend you look for something else.

Not a bad pool cleaner.Got sick of constantly replace parts on my creepy crawler the unit does a good job on pool walls and I havent had to hand vac the pool since buying the unit.
I find it relaxing sitting by the pool Watching it do its thing.

Firstly, the review by RGB is top class and should be cross referenced in the TX30/35 reviews as comprehensive comparison of models.

I've had my OT15 for over a year and can't speak highly enough of it. We have a smallish (7.5m x 3.5) kidney pebblecrete pool. We get a moderate amount of leaves but I just let them sit there and put the robot in every two weeks which probably helps with the life of the unit. I'm amazed but it picks up mostly everything in one cycle, sometimes I put it on for two if there are a lot of leaves. It sometimes misses ...

Here is the bottom line: with a few adjustments to your technique, this robot is reasonably effective as a pool cleaner (3*). It is seemingly without peer below $900 (5*). So overall it earns 4*. Now for the detail. First, note that the Zodiac TX30 (TX 35 without trolley) is with three exceptions identical to the Zodiac OT15 and FX18 cleaners. The exceptions are:
(i) price: the TX30 is intended to be sold through full-service pool shops, so it is much more expensive than the OT15 and FX18 which are intended for on-line stores and available on ...
