What the ST-BX1 Commercial Robotic Pool Cleaner Is
The ST-BX1 is a cordless pool vacuum for scheduled floor cleaning: a 30 W centrifugal pump, a 4,500 mAh lithium battery on 21700 cells, dual brush motors and four driven wheels, in a 3.4 kg body 330 mm across and 219 mm high. No cable runs to the skimmer and no hose hangs off a pole. The unit goes on the pool floor, runs a full cycle, returns and parks when the battery runs low, then lifts out by the handle.
It is a commercial robotic pool cleaner in the operational sense rather than the decorative one. The three numbers a route operator or an importer actually quotes from are runtime, charge time and maximum floor depth, because those decide how many pools one unit covers in a shift and whether a given site can be serviced at all.
Every figure on this page comes from the supplied specification and the product renders. Where the specification is silent, the page says it is silent instead of borrowing a category assumption.
One Charge, One Cycle: The Arithmetic a Route Buyer Runs
Runtime is approximately 100 to 120 minutes on a full charge, and charging takes about 2.5 hours at 12.6 V / 1.8 A. One unit therefore spends roughly four hours per pool: a cleaning cycle in the water, a charge cycle on the deck. In a nine-hour shift that is three pools per unit, and two units working in alternation cover six, because one charges while the other works.
That figure is the whole capacity plan. A service company buying a commercial pool cleaner does not buy units by the shelf metre, it buys them by pools per day, and the ratio here is fixed by the specification rather than by how hard the operator works. Anyone quoting more than three pools per unit per shift without a second battery is quoting a number the machine cannot deliver.
Two practical consequences follow. Each unit needs its own charger, since a 12.6 V / 1.8 A supply is matched to one pack and sharing it queues the day. And the charging point belongs at the van or the plant room, not at the poolside, because a 2.5 hour charge is long enough that the next pool is usually a different address.
30 W Pump, 100–120 Litres per Minute: Which Number to Quote
Wattage describes the motor; flow describes the work. This unit draws 30 W total and moves 100 to 120 litres of water per minute, and it is the flow figure that decides how much debris leaves the floor per pass. A machine can drive quickly and still move little water, which is why a specification sheet quoting only power tells a buyer very little. On a robotic pool vacuum the figure carries more weight than on a hose-fed head, because nothing but the on-board pump is pulling water.
Travel speed is the third number and it is separate again: approximately 18 to 24 metres per minute. Fast travel over a dirty floor is not efficiency, it is a shorter contact time at the intake. On this machine the dual brush motors agitate the floor ahead of the intake, so the robotic pool vacuum lifts loosened material instead of relying on suction alone, and the debris basket under the top lid lifts out for rinsing between pools.
4,500 mAh on 21700 Cells: What the Pack Means for Stock
The pack is 4,500 mAh in a 3S1P arrangement on 21700 cells. That is the larger cell format in this class, and the single-series layout keeps the pack simple to specify: one string, one voltage window, one charger rating of 12.6 V / 1.8 A. For a distributor holding stock, the cell format is the detail that decides whether spares come from the same supply line two seasons later, so it belongs on the purchase record rather than in a brochure.
Runtime moves with load: 100 to 120 minutes is a range, not a fixed figure, because a floor heavy with sand loads the pump harder than a floor needing a light pass. Quote the low end to a customer and the machine will not disappoint them.
The supplied specification lists charger output rather than mains input. A buyer shipping into a specific market should confirm the incoming voltage and plug configuration for that destination before the order is fixed, because neither is stated in the material this page is built from.
IPX8 and 0.3 m to 3 m: Site Checks Before You Quote
The housing is rated IPX8 and the working depth is 0.3 m to 3 m. A 1.2 m pool and a 2.5 m pool both sit inside that window; a floor deeper than 3 m does not, and no setting on the machine changes the rating. That single line settles more pre-sales questions than any other figure here: a commercial pool cleaner quoted against a 4 m hopper is a return rather than a sale.
IPX8 covers continuous immersion within the rated depth. The supplied material makes no statement about storage outside the water, about chemical exposure, or about leaving the unit in a pool between seasons, so this page makes none either. A buyer who needs those answers should get them in writing from the supplier rather than infer them from the rating on a commercial robotic pool cleaner.
Four Driven Wheels, Dual Brush Motors, Random Path Navigation
Four driven wheels hold the body at a stable attitude, which matters on a floor that is not perfectly flat: a body that tilts breaks contact at the intake edge and leaves a strip behind. Wall collision detection turns the unit back into open water when it meets a side, and anti-jam detection keeps the cycle alive when a wheel or brush meets an obstruction.
Navigation is random path, not mapping. The honest reading is that the machine keeps working the floor for the whole runtime instead of stopping when a plan is complete, and it produces overlapping passes rather than a grid. There is no coverage map and no route report, so a route operator judges the cycle by the floor, not by an app. For an automatic pool vacuum bought to work a route that is usually the better trade; where a client wants a printed coverage record, it is not, and a mapping model is the one to ask about.
What the Supplied Specification Does Not List
The specification covers the pump, the battery, the drive, the depth rating, the dimensions and the weight. It lists no app, no remote control, no schedule timer, no mapping or coverage report, no wall climbing and no waterline brushing. It also makes no claim about filtering the full volume of a pool. None of those features should be assumed from the category: what is described here is the machine the specification covers, and a buyer who needs scheduling or mapping should confirm it in writing against the model being quoted rather than assume it from other automatic pool vacuums.
Commercial terms sit outside this page for the same reason. What a buyer pays, how many units an order starts at, and how long production takes all belong in a quotation rather than in product copy, and anything on a product page that looks like a promise on those points should be treated as unconfirmed.
Goods-In Checks a Buyer Can Run in Twenty Minutes
Everything the specification states is testable on arrival with a scale, a tape and a stopwatch. That is the practical value of a narrow spec sheet: it turns an inspection into a checklist rather than an argument.
- Weight. 3.4 kg (7.5 lbs) on a scale, dry.
- Footprint. L330 × W330 × H219 mm measured with a tape, handle folded as shipped.
- Drive. Four wheels, each turning the opposite wheel when rotated by hand.
- Brushes. Both brush motors turning freely, no binding against the housing.
- Rating mark. IPX8 present on the housing and the charger rated 12.6 V / 1.8 A.
- Runtime. A timed full cycle landing inside 100 to 120 minutes on a charged pack.
Who Buys the ST-BX1
This commercial pool cleaner is bought to do a defined job on a route or on a shelf, not as a lifestyle purchase. Five buyer types account for most enquiries:
- Pool service operators running fixed routes, where 100–120 minutes of cleaning against a 2.5 hour charge sets how many pools one unit covers.
- Hotel, resort and villa maintenance teams that need the floor cleaned between scheduled filter runs without a technician entering the water.
- Pool shops and retailers adding a cordless model to a shelf that already carries chemicals, covers and accessories.
- Importers and distributors placing a commercial pool cleaner beside existing suction-side and pressure-side lines, where the cordless unit covers the jobs a hose cannot reach.
- Rental and hire fleets that need a unit a customer can drop into a pool without a cable, a hose or a briefing.
Specifying a Commercial Robotic Pool Cleaner for a Fleet
Four lines settle most fleet specifications, and all four are on the table above:
- Floor depth. 0.3 m to 3 m. A pool with a deeper hopper needs a different model, and discovering that after delivery costs a return.
- Flow. 100–120 litres per minute, which is the working figure behind the 30 W rating.
- Duty cycle. 100–120 minutes of cleaning for 2.5 hours of charging, so three pools per unit per nine-hour shift.
- Scope. Floor only. No wall climbing, no waterline brushing, no claim of full-pool filtration.
Written into a quotation, those four lines answer most of the questions that come back after a container lands. They are also what separates a commercial robotic pool cleaner from a cordless pool vacuum sold on battery life alone, and they keep the commercial pool cleaning equipment conversation on measurable ground rather than on category adjectives.
Frequently Asked Questions
What is the ST-BX1 commercial robotic pool cleaner?
It is a cordless robotic pool cleaner with a 30 W centrifugal pump, a 4,500 mAh lithium battery (3S1P, 21700 cells) and dual brush motors. It runs for approximately 100 to 120 minutes per charge, is rated IPX8 and works on pool floors from 0.3 m to 3 m deep.
How many pools can one ST-BX1 clean in a working day?
One cleaning cycle of 100 to 120 minutes plus a 2.5 hour charge puts one unit at roughly four hours per pool, so three pools in a nine-hour shift. Two units working in alternation cover six, because one charges while the other cleans.
How long does the battery last and how long does charging take?
Runtime is approximately 100 to 120 minutes depending on load on the floor. Charging takes about 2.5 hours at 12.6 V / 1.8 A from the supplied charger.
What water depth can the ST-BX1 work in?
The rating is 0.3 m to 3 m. A floor deeper than 3 m sits outside the specified range, and no setting on the machine extends it.
How much water does the pump move per minute?
The centrifugal pump moves 100 to 120 litres per minute at 30 W total power. On a robotic pool vacuum, flow rate is the figure that decides how much debris leaves the floor per pass, rather than travel speed or wattage alone.
Does the ST-BX1 climb walls or clean the waterline?
No. The supplied specification describes floor cleaning with four driven wheels, dual brush motors and random path navigation. It makes no claim about wall climbing, waterline brushing or filtering the full volume of the pool.
What are the dimensions and the weight?
L330 x W330 x H219 mm at 3.4 kg (7.5 lbs), with a teal carry handle and battery cover on a black body.
What plug type and voltage does the ST-BX1 use?
The unit itself is cordless and carries no plug. The specification lists a charger rated 12.6 V / 1.8 A for a 2.5 hour charge; the mains input and plug configuration are matched to the destination order and should be confirmed in writing for the market being shipped.
What can a buyer check when the container arrives?
Weight at 3.4 kg, the L330 x W330 x H219 mm footprint, four driven wheels turning freely, both brush motors rotating without binding, the IPX8 rating mark, a charger rated 12.6 V / 1.8 A, and a timed cycle landing inside 100 to 120 minutes.
Who is the ST-BX1 built for?
Pool service operators running fixed routes, hotel and resort maintenance teams, pool shops and distributors stocking a cordless model, importers adding to an existing pool equipment range, and rental fleets that need a unit with no cable or hose.
