Works great. Exactly what we wanted. Does a great job cleaning the bottom and sides of our pool.

Works amazing!! No issues so far!

Good machine

This unit's been doing a good job so far, keeping the floors and walls clean.

After owning a previous version, this model has some subtle changes. The pleated filters on the sides of the baskets make sense, but the grab handle on the casing is more difficult to hold when removing the unit from the pool. The cable is 10' shorter than the previous model. Not an issue in my case, but noticeable if you have a pool larger than 18'x35'. Cleaning is still good. It still doesn't fit on the Dolphin caddy correctly and the tracks rub against the caddy wheels when tilted. If you want it to last more than 2 years, take it out of the pool and hose it down daily. Store it out of the pool when not in use. Finding spare parts (especially the bushings) are a challenge. They will wear items and will need to be replaced every 2-4 years. Keeping your pool balanced will make it last longer, too. Power cord to robot does not interfere with Skimmi.

This one does okay, but is not as good as our other Dolphin. It only has one roller. It will also raise up and scoot around the bottom of the pool so it's not picking up anything. It doesn't get the corners either. I usually have to run it through three cycles before it gets “most” if the debris.

Plug and play, and works as described. The only downside for me is the cable length. At 12m/40ft, it's too short for my pool. Unless you can place the controller right at the edge of the pool, you won't get full coverage, which unfortunately isn't an option for me.

Control panel had to be replaced after 3rd use. Buttons bubbled up and unit was extremely hot (manufacturer customer service was great and replaced quickly) Has had no issues cleaning pool, actually cleans our water line when it cleans the walls. Has no problems cleaning sand out of pool if you use the fine debris filter. Worth the purchase. Was having to manually vacuum for the past 3 years and this has kept everything crystal clear.

Worked as expected. Great on leaves. Had to run it 3 times in a row to get small sandy debris

I have a small free form Pebbletec pool. I cannot recommend the Explorer E20. It scrubbed the walls successfully 2 out of 10 attempts. It wasn't heavy enough to stay on the wall. It would float off and glide back down. It also slipped around on the floor. On top of the performance failure, it just seemed like very cheap plastic as compared to my old heavy duty Dolphin DX4. Returned immediately.
