WOW! This is a review for the 1008. I didn't want to get my hopes up on this one. It is cheaper than most of the horrible "cordless" machines, that work half-assed for an hour, and then get stuck or don't clean the pool. This machine is the bomb. It climbs the walls(until its dirt bin is full, and even then about half the wall; my walls are angled at about 60 degrees), and cleans debris my crappy cordless failed to ever clean. Has a 1-2-3 hour cleaning timer, and seems to have a pattern to how it cleans, as in two 3 hours timed sessions it COMPLETELY cleaned a pool the cordless could never clean. THIS IS THE DEAL OF THE CENTURY. You cannot have it to run continuously, but frankly you won't need to. And the cord NEVER gets tangled. It does NOT have a mechanism to stop it from tangling but the key to it never tangling is to set the jets up so their water goes straight out, and not at an angle. I have not needed that feature as it cleans the pool so well with this one setting. To show you how good it is, I just bought a second unit! i just knew I would get a battery operated one for this price but this is the real deal. You can get 3 or 4 of these for the price of 1 of the other electric cleaners. And as we all know you only get about 2 good years out of them before belts strip, etc. Finally, is the brush attached to the unit as good as the crawlers with motorized movement? Let me say, it cleaned up all the stains, small bits of algae, etc. that the cordless never did. And I can see no belt to strip in 2 years either, so to me, a good trade. It will not scrub the part of your pool that is outside of the water, but again, on most corded units I tried that feature never worked very well, and they just ended up sucking air, and then falling to the bottom of the pool. But if you must have that feature, this unit will not do that. And it's cord is 33 ft., which cleans my 36x18 oval, but it might not work on much larger pools, but it seems to only use about 2/3 of the line, so up to 50x25, you will probably be alright, and that is with about 5 feet out of the pool where I am using it, to reach the power unit. I could get more clearance with an extension cord if I needed to. I cannot speak on complicated shaped pools, however. And it will not climb stairs, but the trade off is, it never gets stuck on them either, like many of the fancier units I have had in the past just loved to do. Haha. Does it ever get stuck anywhere? Only once in many cleanings. And I just tugged on the line and it went back to work. And finally I cannot speak on fine sand; I did not have any of that in the bottom of my pool. However it did pick up ALL debris that was there, and some of it was quite small. My thoughts are it WILL pick up sand. NO MORE PULLING THAT DAMN CORDLESS UNIT OUT OF THE POOL AND HAVING TO CHARGE IT! AND I WON'T BE CRYING WHEN THIS ONE DOES STOP WORKING. I CAN JUST USE MY SPARE. This is a great simple electric pool cleaner that does the job. If that is what you are wanting, it does that in spades. I can leave you with this thought: This unit will not be priced like this for very long. Bet on it. If it does, it will run the other companies that make corded units out of business.
