Disclosed in the present utility model are an electric tool and a method for operating same. The electric tool comprises a power supply input, a motive power system, a control system and at least one control button, the motive power system comprising a motor and an operating component driven by the motor, the control system comprising a circuit module to which the at least one control button is electrically connected, wherein the control system is configured to selectively supply electric power to the circuit module or cut off electric power to the circuit module, and adjust an output power of the motive power system, based on the number of times that the at least one control button is operated. The method for operating the electric tool comprises: operating the at least one control button; the control system judging whether to supply electric power to the circuit module or cut off electric power to the circuit module, or adjust an output power of the motive power system, based on the number of times that the at least one control button is operated; and the control system supplying electric power to the circuit module or cutting off electric power to the circuit module, and adjusting the output power of the motive power system, based on the judgement result.

A robotic lawn mower includes a first wheel driven by a first electric wheel motor, a second wheel driven by a second electric wheel motor, a cutting implement driven by an electric cutting implement motor, a power system for powering the electric wheel motors and the electric cutting implement motor, and a controller configured to control operation of the electric wheel motors and the electric cutting implement motor to autonomously mow a yard. The power system includes multiple removable rechargeable battery modules and multiple receptacles, each receptacle configured to receive one of the battery modules.

A stand-on debris blower comprising including a main frame, a pair of front wheels, and a pair of rear wheels. The stand-on debris blower also includes an operator standing platform coupled to the main frame, a control pedestal positioned forward of and above the operator standing platform, and a power source, wherein the power source has a vertically-oriented shaft. A blower assembly is also provided, wherein the blower assembly includes a horizontally-oriented impeller configured to rotate about a vertical axis, the horizontally-oriented impeller being coupled to the vertically-oriented shaft of the power source. Additionally, the blower assembly may include a V-shaped deflector assembly configurable to block air flow to at least a first, a second, or both a first and second discharge chute in the blower assembly.

A blowing-suction machine includes a casing, a suction duct arranged at the front portion of the casing. It further includes a motor and a shredder mechanism that are arranged in the casing in order from rear to front. The front end of the shredder mechanism is connected to the rear end of the suction duct. The shredder mechanism includes blades and a cutting assembly that are arranged in order from rear to front. The blades are arranged on an output shaft of the motor. The cutting assembly is arranged at a rear end of the suction duct for shredding fallen leaves. The cutter cooperates with the secondary cutter such that fallen leaves and rigid trashes can be effectively shredded by the blowing-suction machine. Fallen leaves can be effectively separated from air via the collecting cartridge and the filtering unit, such that the amount of the collected leaves is effectively increased.
