Robotic Pool Cleaners for Pebble Pools: Features
Short answer: Pebble aggregate is a textured pool finish made of plaster with small stones. When you shop for a robotic pool cleaner for this surface, three listing terms matter: the brush type, the suction figure, and the navigation words. The listing title and bullet list state the brush and navigation details, and the suction figure is the seller's own stated number. For each term, read the maker's page next to the listing, and compare robots on those stated details before choosing.
What a pebble aggregate finish is
Pebble aggregate is a pool finish that mixes small stones into a plaster base. The result is a textured surface that is common on inground pools, and the texture is part of the pool's construction, not part of the robot. A listing for a robotic pool cleaner may use the word pebble or aggregate in its title, or it may not name the surface at all. Either way, the surface is not a listed feature of the robot; the robot's listed features are the pool type, the brush, the power source, and the other stated details.
When shoppers ask about pebble pools, they are usually asking whether a robot's brush and drive suit a rough finish. The listing answers part of that question with its brush words, and the maker's page answers the rest. The type of pool finish is closely tied to whether the pool is inground, so the first step is to match the listing's pool type to the pool. The learn article about rough and smooth surfaces explains how surface words appear on listings, and the learn article about gunite pools covers a similar concrete finish.
Brush words on a listing
The brush is the part of a robotic pool cleaner that scrubs the floor and walls. Listings state the brush in a few words: roller brush, brush roller, dual brushes, brush set, rubber brushes, or nylon brushes. These words are the seller's description of the brush material and the brush layout. For a textured finish like pebble aggregate, the brush material is the detail to read, because it is the part that touches the surface.
Some listings name a single brush, others name two or more. The count is a stated detail, and so is the material. A listing that names no brush at all simply has a missing stated detail. The maker's page usually describes what the brush is made for and which pool surfaces the robot is built for. The brush types article walks through the common brush words on this site's listings.
Suction as a stated number
Suction is a term that some listings print as a number, usually in units of flow, such as gallons per hour or a pressure figure. That number is the seller's own stated figure, printed in the listing title or the bullet list. This site does not publish suction figures and does not compare them between robots. When a figure is printed, read it on the listing, then read the maker's page for what the seller says it means for that model.
A listing without a suction number is not a missing feature; it is a listing that does not state that detail. The maker's page and manual are the place to read what the seller claims about the robot's flow. The suction power article explains how this term reads on a listing and what questions to take to the maker's page.
Pool type is the first ordering step
Every robotic pool cleaner listing states a pool type, or it does not. The common words are inground, above ground, or both. A pebble aggregate finish is almost always on an inground pool, because the finish is troweled onto a plaster shell. So the inground word on the listing matters first, and the brush and navigation words come after it.
For an inground pool with pebble walls, the wall climbing word is the next stated detail. For an above ground pool with a textured floor, the above ground word is the match. The site's guides order their picks by these stated details, and the guide for both pool types covers listings that state both. The main robotic pool cleaner guide is the first comparison to read.
Comparing robots by stated details
A shortlist of robots for a pebble pool should compare only the details the listings state. The brush material, the suction figure if one is printed, the navigation words, the pool type, the power source, and the wall climbing words are all stated details. Two listings may use different words for the same feature, so read the maker's page next to each listing.
The site's guides order robots by stated details, not by measured results. If your deck has no outlet near the water, the cordless word is the deciding detail. If you want wall climbing for pebble walls, the wall climbing word is the deciding detail. The cordless guide and the wall climbing guide both compare on those stated details.
Questions for the maker's page
A listing is the first document, and the maker's page is the second. The maker's page states which pool surfaces a robot is built for, what the brush is for, and how the robot's guidance is described. If a listing omits a detail, the maker's page is usually where it appears. When comparing two robots, open both maker pages and read the same detail in both.
Before first use, read the maker's manual for how the robot is placed in the water, how it is charged, and how it is lifted out. For water quality, read the WHO pool water guidelines and the maker's manual, without relying on this article to summarize them. For a cordless robot, the EPA recommends taking used lithium-ion batteries to separate recycling or household hazardous waste collection points, rather than putting them in household garbage or recycling bins. For care between uses, the maintenance tips article follows the maker's manual.

Questions
Does a pebble pool need a special robot?
Listings rarely name pebble. The robot is chosen on stated details: pool type, brush words, suction figure, and navigation words. The maker's page describes the surfaces a robot is built for.
What does the suction figure on a listing mean?
It is the seller's own stated number, usually in units of flow. It is not a comparison this site makes. Read it on the listing and read the maker's page for what it means.
What do brush words tell you?
They state the brush material and count, such as roller, dual brushes, rubber, or nylon. For a textured pebble surface, the material word is the detail to compare.
What are navigation words on a title?
Words like gyro, sensor, ultrasonic, or smart describe how the robot finds its way. They are the seller's description, and the maker's page states more about them.
What if a listing has no brush, suction, or navigation words?
A missing stated detail is common. Read the maker's page next to the listing; it usually states what the listing omits.
Where do you read about battery disposal for a cordless robot?
The EPA recommends taking used lithium-ion batteries to separate recycling or household hazardous waste collection points, not putting them in household garbage or recycling bins.
