Dolphin Carrera 20 - Pool cleaner robot (bottom and walls)

The machine arrived a day earlier than expected. I used it twice already and it has proved to be up to expectations. The filter grading/size collects fine, powder sand size particles and is extremely easy to clean. The machine feels lighter than the declared 6.5kg and can be very comfortably placed in and taken out of the pool.The only problem I faced is from a low, 15cm, step my pool has increasing the depth to about 1/3 of its length. This seems to confuse the machine and it does not do the wall at the shallow end. This is the reason I firstly thought of giving the cleaner only 4 stars. This, shallow end, wall is only 90cm and as such, is easy to brush myself. Overall, an excellent machine that fully meets my expectations.
