Robotic Pool Cleaners for Pools with an Attached Spa
Short answer: A robot is sold by pool type, not by spa. The spa is a separate body of water, usually small and shallow. The listing terms that matter most are cordless (no cable to manage when you lift the robot out and carry it), top-load filter access for quick emptying, and a caddy or lift hook for transport. Read the maker's page for whether a unit suits a small body of water.
Pool and spa: two bodies of water on one property
A property with an attached spa has two bodies of water that share plumbing but hold different water volumes. The spa is the smaller of the two, usually set beside the pool at a slightly higher level. On a robotic cleaner listing, the product is labeled by the pool type it is sold for (inground or above ground), and the spa is rarely named in the title or bullet list.
The Pool & Hot Tub Alliance, the industry association for pools, spas and hot tubs, maintains a national standard for permanently installed residential spas and swim spas, which treats a spa as its own type of water body. For a buyer this means the first question is not whether one robot cleans a spa, but what the listing says about the pool type the unit is sold for.
What a listing can tell you about a pool with a spa
Most robot listings do not mention a spa. The title names the pool type, the power source (cordless or corded), and sometimes surface or wall claims. A missing spa mention is normal. It does not mean the unit is meant for a spa, and it does not mean it is excluded from one.
The pool type label is the first detail to read. A unit labeled for inground pools is sold for inground pools; one labeled for above ground pools is sold for above ground pools. The guide Best Robotic Pool Cleaner for Both Pool Types compares listings that name both pool types.

| Spa suitability | Maker's page and manual |
Cordless models and moving between pool and spa
Cordless is the most useful listing term for a pool with an attached spa. A cordless unit carries its own battery and needs no cable to a power supply at the water. A corded model has a cable that connects to a power supply, and both must be moved if the robot is carried to a second body of water.
A cordless robot is lifted out of the pool and carried to the spa, then lifted back. The word 'cordless' appears in listing titles alongside 'wireless' and 'battery powered.' The Best Cordless Robotic Pool Cleaners guide compares cordless listings by stated details.
Filter access, handles and lifting
A robot that moves between a pool and a spa is lifted out between uses. Listing words that matter for that routine are top-load filter access, a carry handle or lift hook, and a caddy or cart. Top-load access means the filter opens from the top, so the robot can be emptied while it rests on the coping.
Weight is stated on some listings and on the maker's page. Compare that number with your lifting situation. The handle and cart article explains those listing terms.
The filter basket is a listing item. For a robot moved between a pool and a spa, the basket is emptied between uses. The filter types article explains the filter words that appear on listings.
Caddy, storage and charging between uses
A caddy or cart holds the robot out of the water between runs. For a property with a pool and a spa, the caddy matters because the robot is carried between two bodies of water. The maker's manual describes where to set the robot down and how to store the caddy and charger.
Rinsing the robot, emptying the filter basket and storing the unit off season are described in the manual. The storage and maintenance tips articles explain what those instructions cover.
A cordless robot is charged out of the water, as the manual describes. The charging dock or cable is a listing item. At the end of the battery's useful life, the US EPA recommends taking used lithium-ion batteries to a separate collection point rather than putting them in household trash.
Reading the maker's page for the spa question
The maker's page states the intended use of the robot. Model names such as AIPER Scuba and Dolphin Nautilus appear on listings as names, and the maker's page for each model describes the pools it is sold for. The spa is a separate question: read the maker's manual to see whether the unit is intended for a spa.
A listing cannot promise a cleaning outcome. The buyer reads the stated details, then asks the maker about the spa. For water quality in a pool and spa that share plumbing, the WHO guidelines for safe recreational water environments and the maker's manual are the two documents to read.
Why the power outlet position changes the choice
The position of the power outlet decides the practical setup for a pool with a spa. A corded robot needs its power supply near the water. If the spa sits on the other side of the deck from the outlet, a corded unit means moving the supply with the robot. A cordless unit removes that question.

Questions
Can one robot handle both the pool and the attached spa?
In listing terms, a robot is sold by pool type, not by spa. A unit labeled for inground pools is sold for the pool. Whether it suits a small, shallow spa is a question for the maker's page and the manual.
Does a cordless model make it easier to move the robot between the pool and the spa?
Yes, in listing terms. Cordless means the unit carries its own battery and no cable to a power supply. A corded model needs the power supply and cable moved with the robot.
Do you need a robot with wall climbing for a spa?
Wall climbing is a listing claim about what the unit is sold for, not a promise about a specific body of water. Read the maker's page for whether the unit is intended for a spa.
The listing does not mention a spa. What does that mean?
Most listings do not mention spas. The listing names the pool type and features. The spa question is answered on the maker's page and in the manual.
How do you move the robot from the pool to the spa?
A caddy or cart is a listing item for transporting the robot. A lift hook or carry handle is another listing item. The manual describes lifting and setting the robot down.
Should you choose a corded or cordless model when there is no outlet near the spa?
A corded robot needs its power supply near the water. If the spa is away from the outlet, a cordless unit removes the need to move a power supply and cable with the robot.
