More Power, More Speed: Pumps water 1.9X faster than other pumps. With an open impeller, flow rate of up to 3600 GPH and max hydraulic capacity of 30FT, this 1/2 HP submersible water pump can make standing water disappear quickly, eliminating the danger of flooding..Auto-Flo Technology Saves Time and Effort: Smartbot's US patented Auto-Flo sensing technology detects rising water levels and automatically pumps out water, eliminating the risk of water damage. When Auto-Flo detects a water level of 2” (approximately 50.8 mm), the water pump is immediately turned on. When water level drops to below the normal level, Auto-Flo shuts down the pump to protect the motor from burns due to dry running..Knock Over Operation & Dry Run Protection：Works automatically even when accidentally knocked over. It monitors the water level and stops automatically when the surrounding water level drops to a normal level or if it encounters a blockage. The sensor prevents the machine from dry running and eventual machine failure..Portable and Efficient: Small But Mighty at just 8*7*10 inches. You can easily carry the Smartbot from the basement to the garden or pool at any time, to effectively drain all the water..6 Adaptors (2*2”,1-1⁄2”,1-1⁄4”,1”, 3⁄4”): 6 adaptors depending on the urgency and speed required for draining water. Our largest 2'' adapters need 2'' water pipes to achieve a max 3600 GPH of pumping water, which requires a 2'' hose. Smartbot can handle different types of water including clear water, rainwater, spring water, river water, lake water, etc (with up to 1/4" Diameter Solids).
