Gisam 250Bar Brushless Electric High Pressure Washer Gun 4Gear Power Home Car Washing Water Spray Gun for Makita 18V Battery Pin

With longer use, the pressure proves lower than the seller claims — users estimate actual values at 100–150 bar instead of 250. Battery runtime for one complete car wash is adequate, but water consumption is very high (5-liter bucket in one minute). The device works better when connected to mains water; when drawing from a bucket, pressure is lower. Some users reported that original Makita batteries fit very tightly.

The main complaint concerns the missing shut-off valve on the hose — water flows even when the device is not in use, so you must turn off the water at the tap. Several buyers complained about lower pressure than expected and the quality of some accessories (e.g., broken rotating nozzle). The share of negative ratings is low (3.7%), but most reviews were written without long-term testing.
