Robot sweeper replacement motor that delivers predictable rotation across common voltages. Confidence for DIY repairers and maintenance technicians who need measurable swap-in performance. Will Zhixteu RC500-KN Carbon Brush Motor match your sweeper's fittings and cleaning requirements?

⚡ At a Glance
  • Speed Performance: No-load speeds measured at 2600–5500 RPM across test voltages
  • Best for: Replacement motors for robot sweepers and small household robotics
  • Not ideal for: High-torque industrial applications or continuous heavy-load use

Test data lists no-load speeds at 6.0V, 7.4V and 12V, with low corresponding currents. Designed primarily for brush rotation tasks in consumer robot sweepers.


Predictable brush rotation – with a 6–12V tested speed range

No-load test figures show 2600 RPM at 6.0V, 3250 RPM at 7.4V and 5500 RPM at 12V, recorded alongside currents of roughly 30–34 mA. These metrics allow straightforward matching of rotational speed to cleaning head requirements.

Consistent speed data helps choose the right replacement for a sweeper's brush assembly, reducing guesswork during repairs and ensuring cleaning performance aligns with expectations.

Modest idle power draw – thanks to low no-load current

Measured no-load currents remain in a narrow band, approximately 30 mA at lower voltages and up to 34 mA at 12V according to test entries. Low idle draw indicates limited battery drain when the motor is spinning without significant load.

Lower standby consumption helps preserve battery life in cordless sweepers during idle or light operation, improving overall runtime between charges.

Simple mechanical fit for brush shafts – with a round spindle design

Product description specifies a round spindle DC motor intended for robot sweeper machines, indicating a shaft form suited to direct coupling with brush attachments. The round spindle approach commonly simplifies mounting within typical sweeper assemblies.

Direct spindle coupling simplifies replacements and shortens workshop time for routine motor swaps in compatible machines.

✨ The 4 Key Reasons for Zhixteu RC500-KN Carbon Brush Motor
  1. Low idle current – Extends battery life during standby and between cycles
  2. Round spindle shaft – Simplifies swap-in replacement for compatible brush heads
  3. Wide voltage compatibility – Works across common 6–12V robot power systems
  4. Predictable speed scaling – Allows brush rotation to be tuned by supply voltage
