Mammotion Spino E1 Cordless Robotic Pool Cleaner
The SKIP — A ~$499 budget pick and the one to skip — WIRED scored it 6/10, measuring only ~80% debris pickup, a build that 'suggests a child's toy,' water getting into the charging port, and battery life well under claim; owners sit at 3.7★ / 34

Filtration is rated in microns (µm — millionths of a meter): the smallest particle the filter reliably traps, so a lower number is a finer filter. A human hair is ~70 µm; ultra-fine (~3–10 µm) catches the silt and dead algae that make water hazy. "µm not published" means the maker states no number — which is information in itself.
Pros
- Strong on paper — a claimed 5,800 GPH suction, 4-in-1 floor/wall/waterline cleaning, and a current-model warranty at a ~$499 sale price
- Climbs sloped walls (rated to 110°) and parks itself at the surface for easier retrieval
Cons
- The only contender here with a credentialed independent pan: WIRED scored it 6/10 — 'a budget pool bot that comes up short' — measuring only ~80% debris pickup and concluding the robot 'simply may be underpowered'
- Owners agree it's the weakest of the group — 3.7★ across just 29 ratings (a thin sample, so read it as 'buyer beware,' not a final verdict)
- WIRED found water getting into the charging port after every run and a build that 'suggests a child's toy more than a piece of expensive home equipment'; measured battery life topped out 'between 2.25 and 2.75 hours,' well under Mammotion's 3.5-hour claim
It misses the pool. Three owners report incomplete coverage on plain shapes — "we have a 27 ft round flat bottom pool and it never cleans the entire bottom"; "maybe works if you have no creases in your pool"; "it failed to crawl the walls of my pool". The filter is the second fault and a specific one: "the filter screen is not a small enough micron to capture the fine sedimen[t]", from an owner whose water went cloudy. Battery and reliability round it out — "the charge does not last long enough and it stops working" — and one buyer could not get it running at all after following the quick-start guide.
