How we picked
This guide pools listings whose live price read under $400 when the pool was read, the window for this budget guide. The pool read 10 priced matches; near-duplicates were folded into 7 listings, and all 7 are picks. The listings are compared on the details each title states: the kind (robotic or suction-side), the pool type (in-ground, above ground or both), cordless operation, and wall climbing. The ordering rule ranks a listing that states a type first, then by the number of other stated details, most first, then by the order of the pool file. One pick, the Pentair Kreepy Krauly Kruiser, states no type in its title and ranks last. Live prices print beside each pick with the time they were read.
How to choose
Robotic, suction-side or no type in the title
6 of the 7 picks state a type in their title: 5 robotic and 1 suction-side. A robotic cleaner has its own motor and filter, while a suction-side cleaner runs on the pool's pump through a skimmer or suction line. The Pentair title states no type, so the type is not stated by the seller; the reader checks the maker's manual for how the cleaner is powered.
In-ground, above ground or both pool types named
The titles name in-ground pools, above ground pools, or both. The C1 title names both pool types; one B1 title names above ground pools alone; four titles name in-ground pools; one title names no pool type. Pool size and shape are not stated and are questions for the maker's page.
Cordless or cord not stated
5 of the 7 picks state cordless in their title. The two non-cordless titles are the Zodiac, which says no batteries, and the Pentair, which states neither cordless nor a battery. Run time and charging time are not stated in any title; the maker's manual covers them.
Wall climbing as a title claim
One pick states wall climbing in its title. Wall climbing is a claim about the cleaner's stated action, not a promise about waterline, steps or a surface. No other title in this list states wall climbing.
Pump, hose and fittings as manual questions
For a suction-side cleaner, the reader checks the pool's pump, suction line and skimmer in the maker's manual. For robotic cleaners, the manual covers charging and placement. The ENERGY STAR pool pump page explains how the pump works in general; no figure from it is restated here.
What this guide leaves out (and why)
The catalogue holds no surface, filter type, run time, coverage, weight, cable length or hose length, and no navigation or app data. None of those appear in this guide. Questions about them belong on the maker's page, and water care questions on the World Health Organization and Pool & Hot Tub Alliance pages listed under sources.
Questions
How are the picks ordered in this guide?
Listings that state a cleaner type in their title rank first. Among them, the count of other stated details (pool type, cordless, wall climbing) decides the order, most first, then the order of the pool file. The Pentair, which states no type, ranks last.
Which pick states the most details in its title?
The WYBOT B1 Cordless Robotic Pool Vacuum with quad-roller brushes is the top pick. Its title states a robotic type, cordless, in-ground pools and wall climbing, which is more stated details than any other listing in this guide.
Does this guide cover surfaces, run time, safety in the water or water care?
No. The catalogue has no data for pool surface, filter type, run time, coverage, or navigation, and this guide makes no claims about safety in the water or water care. The maker's manual answers power and charging questions, and the World Health Organization and Pool & Hot Tub Alliance pages handle water care and standards.
Why is the Pentair Kreepy Krauly listed last?
Its title names in-ground pools but does not state a cleaner type. The ordering rule puts listings with a stated type first, so a title with no type ranks after all six that state robotic or suction-side.
What should a buyer check before choosing a suction-side cleaner?
A suction-side cleaner runs on the pool's pump. The buyer checks the pump, skimmer and fittings in the maker's manual, and reads the ENERGY STAR pool pump page for how pool pumps work in general. This guide's listed detail for the Zodiac is the suction-side type and in-ground pools.
Do any picks state a run time or coverage?
No. None of the 7 listing titles states a run time, coverage, filter type or pool surface. Those details are not stated by the seller and should be read on the maker's page.
