How we picked
This guide covers 5 robotic pool cleaner listings whose live prices fell within the under $400 window when the pool was read, per the Owner window rule. The robots are compared on the details stated in each listing title: whether the title names a pool type (inground, above ground, or both), whether it says cordless, and whether it claims wall climbing. The ordering rule ranks listings first by whether a pool type is named, then by the number of other stated details (cordless, wall climbing), then by the order in the pool file. 4 of the 5 picks are WYBOT listings; the guide notes this plainly. No run time, filter, or safety claims are made; read the listing and maker's page for those.
How to choose
Inground, above ground or both in the title
Look at what the listing title names. In this guide, 1 pick names both inground and above ground pools, 2 name inground pools, 1 names above ground pools, and 1 names no pool type. The title's wording is the seller's claim; it does not guarantee a fit for a specific pool size, shape, or depth. If a title names no pool type, that detail is not stated by the seller.
Cordless as a title word, and what not stated means
All 5 picks in this guide say cordless in the title. A cordless robot has no cable to the deck and is charged out of the water as the maker's manual describes. A listing without the word cordless would be 'not stated by the seller', never 'corded'. Here, every pick states cordless, so that detail is consistent.
Wall climbing as the seller's claim
Only 1 pick in this guide states a wall climbing claim in its title. That claim is the seller's wording, not a measure of how well or how high the robot climbs. The other 4 picks do not state wall climbing, so that detail is not stated by the seller for them.
Run time, filter and app: read them on the listing
This guide does not read run time, charge time, filter type, app support, or weight from the catalogue. Those details are not in the listing titles here. To compare them, read the listing page and the maker's page for each robot. The guide cannot say how long a battery lasts or what the filter catches.
Power, water and the maker's manual
For questions about power and water, the maker's manual and a licensed electrician are where to read about them. The Pool & Hot Tub Alliance and UL Solutions pages linked in the sources offer industry standards and safety science. This guide does not give electrical or water safety advice.
What this guide leaves out (and why)
This guide compares robots only on stated details: pool type, cordless, and wall climbing. It does not cover pool size limits, cleaning performance, durability, or warranty terms, because the catalogue has no data for them. Buyers should read the listing and maker's page for those specifics.
Questions
Does this guide cover run time, filters, safety or warranty?
No. This guide compares robots only on details stated in each listing title: pool type, cordless, and wall climbing. The catalogue has no data for run time, charge time, filter type, safety certifications, or warranty terms. Read the listing and the maker's page for those. For power and water questions, consult the maker's manual and a licensed electrician, and see the PHTA and UL pages in the sources.
What does 'not stated by the seller' mean?
When a listing title does not mention a detail, such as pool type or wall climbing, this guide writes 'not stated by the seller'. It does not guess or assume the opposite. For example, a pick without a wall claim is not said to lack wall climbing; it simply has no stated claim. Check the listing page for more details.
Are all these robots cordless?
Yes, all 5 picks in this guide say cordless in their listing titles. That means the seller states they have no cable to the deck and are charged out of the water as the maker's manual describes. This guide does not state run time or charge time, as those are not read from the catalogue.
Which pick is best for an inground pool?
Two picks name inground pools in their titles: the WYBOT B1 Robotic Pool Vacuum Cordless (which also states wall climbing) and the WYBOT B1 Cordless Robotic Pool Vacuum for Inground Pools. The WYBOT C1 names both inground and above ground pools. Choose based on whether you want a wall claim or a both-pool-type listing.
Why are 4 of the 5 picks WYBOT listings?
The pool for this guide, priced within the under $400 window, contains 5 listings, and 4 of them are WYBOT brand. The guide compares these robots on stated details only; it does not rank brands or imply one maker is better. The 1 non-WYBOT pick is the WYBOT C1, which is also WYBOT, so all 5 are WYBOT. This is stated plainly.
