Betta SE Plus vs Beatbot iSkim Ultra: Key Trade-offs
Betta SE Plus and Beatbot iSkim Ultra represent different buying priorities. SE Plus offers a relatively straightforward automatic routine with backup charging. Ultra adds connected controls and dedicated edge-collection hardware. Our recommendation depends on your pool and maintenance routine, not on a universal winner.

Choose the ownership routine first
SE Plus uses a handheld remote; Ultra offers app control. That is a meaningful convenience difference if you want to manage operation from a phone. It is less meaningful if you already walk beside the pool to inspect equipment each morning.
Write down who will empty the basket and retrieve the robot. If several family members share maintenance, decide whether they prefer a physical remote or an app setup. More controls are useful only when the person doing the work will actually use them. Neither choice removes the need to inspect the machine in person.
Separate edge collection from filtration
Ultra includes dual side brushes. SE Plus is documented with a 200-micrometer basket, while Ultra’s product FAQ states 380 micrometers. A larger micron number is not a finer filter specification.
This creates a more useful decision than comparing a single overall “power” claim. If your main frustration is material floating against the perimeter, investigate how the collection hardware behaves near your pool wall. If fine suspended material is the concern, investigate actual filtration requirements. We have not conducted a matched pickup test and do not turn these specifications into a cleaning-speed ranking.
Confirm fit before comparing extras
Betta publishes a 3.5-inch minimum operating depth for SE Plus. We do not infer an equivalent Ultra limit from a product photograph or its above-ground-pool marketing. Obtain exact guidance if a shelf or unusual edge is accessible to the robot.
One practical approach is to photograph the shallowest area and measure its depth and opening. Keep those details with your shopping notes. A feature-rich robot that repeatedly reaches an unsuitable shelf can create more supervision work than a simpler unit that fits the pool correctly. This is a fit-based inference, not a measured reliability claim.
Compare the complete cost of ownership
Both models support solar power and an additional charging method, but the required hardware differs. Confirm the correct included charger for the actual listing. Do not buy an unrelated adapter because its connector looks similar.
Consider optional consumables separately from the basic job of removing floating debris. Our recommendation is SE Plus for an owner who values direct controls and an uncomplicated surface-cleaning routine. Consider Ultra when its edge hardware and app functions solve specific problems you have identified. Before ordering either, locate the replacement basket and service contact so that routine wear does not become an unexpected dead end.
Common questions
Is Ultra automatically better because it has more features?
No. The useful choice depends on pool fit, debris location and which controls you need.
Which has the finer stated filter?
The cited SE Plus specification is 200 micrometers; Ultra’s product FAQ states 380 micrometers. Lower is finer as a nominal mesh comparison, but not proof of complete particle capture.
Can both charge without sunshine?
Both support an additional charging method. Confirm the correct charger is included with your chosen listing.
Which should I choose for a shallow ledge?
SE Plus has a published 3.5-inch minimum depth. Confirm exact compatibility for the ledge and obtain Ultra’s specific requirements rather than assuming a match.
