We offer a powerful suction "pool cleaner." If you prioritize time efficiency and reliability, we recommend our manual cleaner over fully automatic ones. Calculating the cleaning time for 1(m²) at 5 seconds, it would take about 30 minutes for a 15×25m pool for the entire area, and less than 15 minutes for just the dirty corners and seams. (Fully automatic cleaners can take 2 to 4 hours and may leave some spots uncleaned.) Please feel free to contact us if you have any inquiries. 【Features】 ■ The pump has strong suction power and an adjustable aluminum handle of 2.5 to 4.8m, allowing for cleaning from outside the pool. ■ The included hose floats on water, efficiently cleaning debris from the bottom without stirring it up. ■ The polycarbonate resin head has good adhesion and is equipped with casters, easily removing even fine debris with a light push. ■ The head can bend at a right angle, allowing for cleaning in corners of the pool where debris tends to accumulate. *For more details, please download the PDF or feel free to contact us.
