Questions and answers
how do I know which model of cleaner BWT I have?
Look for the silver or white label attached to the robot chassis (usually near the motor or on the bottom). It will indicate the exact model (ex: BWT D200, P400, Cosmy 150) and the reference number.
are they original spare parts BWT?
Most wear parts (filters, brushes, tracks) are designed to be changed by the user without complex tools (DIY - Do It Yourself system). For engine block changes or complex internal repairs, we recommend contacting our official technical service.
My robot BWT is old (Line Aquabot), do you have parts?
BWT purchased Aquabot a few years ago. Many components are compatible or have modern substitutes. Check with us if you can't find your discontinued model on the web.
how often should I change the 4D filters?
It depends on the use and dirtiness of the pool. Generally, it is recommended to change them every 2 seasons or when you notice that, after washing, the fabric is still stiff or saturated and the robot loses suction.
has your robot cleaner BWT lost suction power or stopped climbing the walls? You don't need to buy new equipment. At Quimipool, as official distributors, we offer you the complete catalog of spare parts for pool cleaners BWT (Best Water Technology).

Parts Catalog: Find what your Robot Needs
To facilitate your purchase, we classify spare parts according to their function in your equipment. Identifying the fault is the first step to solve it.
1. 4D Filters and Filter Baskets
The heart of BWT 's cleaning is its 4D hyperfine microfiber filter technology. If you notice the robot is kicking up dust instead of vacuuming it up, it's time to change the filters.
- Available for: BWT D100, D200, D300, P400, P500 and Cosmy series.
- Recommendation: Always have a spare set of filters to alternate during deep cleaning.
2. Rollers and Brushes (PVA and PVC)
Traction is vital. If your cleaner slips on walls or does not go above the waterline, it is usually due to brush wear.
- PVA brushes: Essential for tiled or ceramic pools (better grip).
- PVC brushes: Ideal for reinforced sheet or liner.
- Vibratory rollers: Help to remove dirt adhered to the bottom.
3. Transmission: Belts, Tracks and Wheels
They are the "tires" of your robot. Over time and with chemicals, the tracks can stretch or break, preventing the robot from moving forward.
- Drive belts: Check if the robot moves slowly.
- Tracks: Replace if they show visible cracks or loss of teeth.
4. Electronics and Power Supply
From the motor block to the floating cable with anti-knot system (Swivel). If the robot does not start or stops mid-cycle, the problem is usually here or in the external power supply.

Professional Maintenance Tips for your BWT
To maximize the profitability of your spare parts, our technicians recommend following this routine. Good maintenance prevents 80% of serious breakdowns.
- Post-Cycle Rinse: Never let the robot dry with dirt inside. Rinse the 4D filters with fresh water after each use to prevent the micro-pores from solidifying with scale and debris.
- Shaded Storage: UV rays are the #1 enemy of plastics and cables. Always store your robot and power supply (transformer) in a dry, shaded place or use a protective cover.
- Cable Care: When removing the robot from the water, never pull on the cable. Use the carrying handle. Pulling on the cable alone can cause connection failures in the motor block.
- Water Chemistry: Extreme levels of chlorine or acidic pH accelerate the wear of the rubber (tracks and brushes). Remove the robot if shock chlorination is to be performed.
doubts about compatibility?
We know that distinguishing between a replacement part for a BWT Tornado D500 and a Cosmy 200 can be confusing. Don't risk ordering the wrong part.
