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
- The highest owner rating in the budget tier — 4.6★ across 139 Amazon ratings on the current (2026) six-roller B1
- A true 4-in-1: floor, walls, and waterline (with a waterline-only mode) plus edge/corner side brushes — coverage you usually pay more for
- Popular Science-reviewed, with a modular quick-release design built for easy part replacement (a durability edge in a tier of disposables)
Cons
- Small-pool rated — up to ~1,150 sq ft, tighter than the WYBOT C1's ~1,615 sq ft; a big-pool robot it isn't
- A thin and heavily incentivised review base — its listing shows 4.7★ but ~77% of visible reviews are free-product Amazon Vine, with no US verified purchasers, against the C1's 4.2★ across 827 paying owners
- ~120-minute runtime, and WYBOT doesn't (yet) document a user-replaceable battery pack — treat the battery as sealed until confirmed
- WYBOT brand flag — three issues (verified 2026-07-20): (1) Questionable customer service — warranty claims frequently go unanswered, clustering right at the 2-year warranty edge ("multiple emails sent to Wybot… no response", "they dont honor their warranty"); one C1 owner is the exception, reporting a fast replacement. (2) Relisting / Amazon-Vine-seeding — WYBOT pads fresh listings with free-product Vine reviews and its ASINs drift often (the B1's rosy 4.7★/65 sits on a ~77%-Vine relisting; the newer C1 listing runs ~80% Vine), so read the review base before trusting any WYBOT star rating. (3) Battery reliability with no genuine replacement — packs fade and WYBOT sells no purchasable genuine replacement (the batteries are user-serviceable, but no pack is sold in its US/EU stores or on Amazon), so the robot is the consumable. Buy where returns are easy and don't count on post-warranty help.
Pro review “It's so easy to use it almost feels like a toy, but it's actually a tool.”— Stan Horaczek, Popular Science
✓ Safety: no active recall — No CPSC recall touches the WYBOT B1 (the Apr 2026 recall was the WYBOT S1/WY200 + the Osprey 700 Max). It's still a lithium battery — buy current stock, use the supplied charger, and charge it away from anything flammable.
