The Wall Whale Classic Swimming Pool Brush

What this brush head does differently

The Wall Whale is an 18-inch brush head whose tail design is listed as forcing the brush against the wall with more than 10x the force. The seller describes it for reliable weekly maintenance and tough algae problems.

• Pole required: The listing says it attaches to your existing pool pole; no hose, pump, filter, or motor is needed.
• Seller claims: The product page presents the tail as the key difference from ordinary brushing, so compare it with conventional brushes if wall contact matters most.

The listing does not state a specific pole diameter, so confirm connector compatibility separately before buying.
