Well, my Blue Pearl arrived last night. My overall review would be incomplete. My pool wasn't very dirty and I have some questions about the robot.

It is fast and light. It kept popping wheelies crossing my 18 X 43 plaster pool. That had me concerned about its scrubbing. Also, it didn't spend much time around the tiles. Usually, it turned around before climbing most walls. When it did climb walls, it spent little time on tile before going back down. The manual says it is important that the handle be parallel with the water when it reaches the surface. It wasn't. It also recommends that the handle be set 1 less than the last slots diagonally. I tried that, the one before it and last slot to see if it made any difference. Didn't notice anyway better than the manner suggested.

I can only compare it to the pool rover plus and the aquabot mark V, that I have owned. It has much more sophisticated steering than both. Preliminarily, it appears to do a good job cleaning the pool floor fast. Its method of turning all the time, changing speeds, appears to really minimze any chance of getting stuck or in a rut. Like posted here before, it didn't remove all of my algae, but did seem to get most dirt and leaves in a cycle that lasted about 90 minutes. For experimantation, I ran another cycle. Pool was clean afterword but pool wasn't dirty enough to be a good test.

Compared ot the mark V original Aquabot, it cleans and moves much faster. As such, it should be in pool for about 1/3rd the time, which means it shoudl go 3 times longer before maintenance issues develop. Mechanically, they are similar. However, that speed might be at some cost. The scrubbign of the aquabot is probably better, given it so slowly moves over and over the pool. Also, although the Aqubot tends to "waste" alot of time on the tiles, the Blue Pearl barely touched them.

As for the Blue Pearl versus the pool rover plus, I can't do much of a comparison since they never did the same pool. However, I still question the pool rovers very basic steering system covering a whole pool floor if the pool has any irregualrities. The Blue Pearl does seem to have good steering, and neither really cleaned the tiles.

For $749 including delivery, brand new, with 2 year warranty, it's probably as good of deal as any. I'd be interested in it how it compares to Aquabot Turbos, especially the new Turbo T's and Turbo T2's. However, those models, even refrubished or blmished run over $100 more.
