Rough surfaces. The combined brush is the difference.
The Dolphin M 500 comes with one of two brushes at the same price. This is the CB — the combined brush, for marbelite, quartz, granite or pebble. Pick by what your pool is lined with, because the price will not decide it for you.

The Maytronics Dolphin M 500 CB is a robotic pool cleaner for South African residential pools up to 12 metres. It cleans floors, walls and the waterline, uses the Combined Brush (CB) for rough surfaces - quartz, granite or pebbles, filters through fine and ultra-fine cartridges, connects to the MyDolphin Plus app and ships with a caddy as standard. It is sold in the store as the Dolphin M500i CB.
Rated to 12 m, floors, walls and waterline, 11 kg with a caddy included as standard. The Combined Brush (CB) is fitted for rough surfaces - quartz, granite or pebbles.
The brush is the whole decision
The M 500 is one machine with two brush options. This is the combined brush, made for quartz, granite, pebble and marbelite — rough surfaces that chew through a softer brush and need the harder compound to scrub properly. Everything else about the two is identical, including the price, so the only way to lose here is to never be asked which surface you have.

Fine and ultra-fine, in cartridges
Two cartridge grades rather than one basket doing both jobs: the fine cartridge for everyday grit, the ultra-fine when the water has gone dusty and you want it polished. They lift out and rinse off.

Eleven kilograms, and a caddy in the box
A wet robot is heavier than a dry one and the lift out of the water is the part people underestimate. At 11 kg with a caddy included as standard, this is one you wheel rather than carry. The swivel cable is the other half of that — an 18 m cable that does not wind itself into a knot over a season.

Floor, walls and waterline, scanned not guessed
A triple-active brush and CleverClean scanning with the Dynamic Dual Drive Motor, so it maps a route instead of bouncing off things. Rated to 12 m and app-connected through MyDolphin Plus.

M 500 CB against M 500 WB
These are the same cleaner. The only difference is the brush, and it is not a preference — it is a match to what your pool is lined with. Both cost the same, so choosing wrong gains you nothing and costs you scrubbing performance. If you are not sure what your surface is, send us a photo before you order.
Questions people ask about the M500i CB (marbelite pools)
What is the difference between the Dolphin M500i CB and the M500i WB?
Only the brush. The CB is made for rough surfaces - quartz, granite or pebbles; the WB is made for fibreglass, tile and vinyl. Pool size, coverage, filtration, caddy, warranty and price are identical.
How do I tell which brush my pool needs?
Run your hand across the wall below the waterline. If it is smooth and slightly glossy it is fibreglass, tile or vinyl and you want the WB. If it is grainy or you can feel the aggregate, it is marbelite, quartz or pebble and you want the CB. If you are not certain, send us a photo of the wall and the waterline and we will tell you.
