Technical Data & Calculation Methods

Published specifications for two machines, plus the arithmetic behind runtime, productivity and refill intervals. Every formula below is written so that you can substitute your own numbers and re-run it — on our machines or on a competitor's.

What is and is not on this page

The specifications are transcribed from our product documentation. The methods are standard engineering arithmetic — not test results. Where a figure is not published by us or by a competitor, this page says so rather than filling the gap with an estimate.

Published: tank capacities, widths, motor ratings, weights, dimensions — from the product manual.
Not published: price per model (25 of our machines are quoted per order, not from a list), and competitor specifications that their public pages do not state.
Calculated, not measured: every runtime and productivity figure below is derived from published inputs using the stated formula. Your result will differ because your floor, operator and duty cycle differ.

Method 1: calculating runtime from battery capacity

Manufacturers publish voltage and amp-hours. They rarely publish how that becomes hours on the floor. Three steps convert one into the other.

Step 1 — battery energy (Wh) = voltage (V) x capacity (Ah)

Step 2 — usable energy (Wh) = battery energy x depth of discharge x discharge efficiency

Step 3 — runtime (h) = usable energy / average power draw (W)

Chemistry	Depth of discharge	Discharge efficiency
Lead-acid	about 80%	about 85%
Lithium (LiFePO4)	about 90%	about 95%

Worked example — A500, 24 V / 100 Ah

Battery energy: 24 V x 100 Ah = 2,400 Wh
Lead-acid usable: 2,400 x 0.80 x 0.85 = 1,632 Wh → 2.7 h at 600 W
Lithium usable: 2,400 x 0.90 x 0.95 = 2,052 Wh → 3.4 h at 600 W
Our manual states 3 to 4 h working time, which corresponds to an average draw of 600 to 800 W — consistent with a 550 W brush motor and 500 W vacuum motor running below peak.

Method 2: converting rated productivity into realistic output

Rated productivity is a theoretical maximum, usually deck width multiplied by travel speed. No operator achieves it in a real building, and the gap is predictable.

Rated (m²/h) = cleaning width (m) x travel speed (m/h)

A500: 0.5 m x 4,400 m/h = 2,200 m²/h — the figure in our manual.

Time loss	Typical effect
Turning and repositioning at rack ends	loses 10 to 20%
Obstacle diversion around pillars and pallets	loses 10 to 25% in dense racking
Solution refills and recovery empties	loses 5 to 15%, higher with large floor areas
Operator fatigue over a full shift	loses 10 to 20% on a walk-behind

The ranges above are typical field outcomes reported across the industry, not measurements we have taken in your building. Combined, they put realistic output at roughly 50 to 70% of rated for a walk-behind in racked warehouses, with the lower end applying to dense racking and frequent refills. Time one real route with a stopwatch before relying on any published figure, ours included.

Method 3: calculating the refill interval

On most machines the tank runs out before the battery does. The interval is simple arithmetic, and it is often the real limit on shift length.

Tank runtime (h) = solution tank (L) / flow rate (L/min) / 60

Solution flow	A500 (50 L)	B260R60 (200 L)
0.30 L/min — light soil	2.8 h	11.1 h
0.45 L/min — standard	1.9 h	7.4 h
0.60 L/min — heavy soil	1.4 h	5.6 h

Compare the two limits and take the smaller number. On the A500 at standard flow the tank empties in about 1.9 h while a lithium battery is still good for 2.6 to 3.4 h — so the operator stops to refill, not to recharge. On the B260R60 the 200 L tank outlasts most shifts at any of these flow rates, which is the main practical argument for a ride-on of that size.

Three widths that are not interchangeable

A sweeper scrubber states three different widths. They describe three different things, and the largest is not the one that limits your productivity.

Width	What it measures	Use it to calculate
Sweeping width	Full span of the side brushes, which extend beyond the body	Debris collection per pass — not scrubbing
Cleaning width	Scrubbing footprint of the brush deck underneath	Productivity and pass count — this is the binding number
Squeegee width	Water recovery span at the rear	How much water is recovered, not how much is scrubbed

On the B260R60 the difference between 1,350 mm sweeping width and 900 mm cleaning width is 450 mm of floor that is swept but not scrubbed. On a floor with heavy oil film that strip needs a second pass or a wider brush deck.

Data provenance

Specifications transcribed from Aikerui product documentation for the A500 and B260R60. Formulas are standard electrical and operational arithmetic and are stated in full so they can be checked.

The percentage ranges in Method 2 are industry-typical outcomes rather than measurements taken by us, and are labelled as such. If you need a figure you can rely on for procurement, time a route on your own floor.
