BWT, and B100 Replacement Parts: Complete Parts List with Prices

The B100 is the entry-level model in the Aquatron BWT : 4-wheel drive with a 4D filter and the same mechanical design as the B200; it does not have its own floating cable listed in the replacement parts catalog because this model uses a different power supply system. Wear and tear is concentrated on the transformer—which includes the filter-full indicator light—and on the brush wheels, which serve the dual purpose of providing traction and scrubbing. Here is the complete parts list with prices and links to each part.

The transformer: the part that generates the most inquiries

The B100 uses the same transformer with a filter-full indicator light as the rest of the D-Line series. If the robot won’t start or the indicator isn’t working, this is the first part to check.

Drivetrain: wheels, bearings, and gears

The four drive wheels serve a dual purpose—propulsion and scrubbing—so wear and tear on them directly affects cleaning quality, not just movement.

Motor and filtration: propeller and brush assembly

Quick Diagnosis: From Symptom to Part

Before buying the transformer (€379)

The transformer is the most expensive part in the B100 parts list. Before you decide:

• Check the electrical connector (€35.90), which connects the robot’s cable to the transformer and is the part that fails most often.
• Check the power cord for the transformer (€29.90): a frayed cord can mimic a transformer failure.
• Check the wall outlet and the circuit breaker before assuming the problem is with the robot.

Is it worth repairing or buying a new one?

If the repair cost exceeds 60–70% of the price of a new B100, consider replacing the entire unit. The transformer (€379) is by far the single part that comes closest to that threshold on its own, so if you also need the brush assembly (€78.95), do the math based on the current price of the model. For wheel or propeller failures, repairing is still the most cost-effective option.

Maintenance that prevents almost all breakdowns

• Remove and rinse the 4D filter after each cycle; the filter’s vibration helps, but a clogged filter still puts a strain on the motor.
• Check the propeller for tangled hair or string after each extended use.
• Check the brush wheels periodically: since they serve a dual purpose of propulsion and scrubbing, their wear affects performance sooner than it would on a robot with tracks.
• Store the B100 in the shade and unplugged from the power supply when not in use.
