Bucher CityCat V20e (80 kWh battery)

The CityCat V20e is Bucher Municipal's second-generation fully electric compact sweeper and can be used around the clock. With 2100 kg payload and 4800 kg gross vehicle weight, it has the same load capacity as the diesel version, but without local emissions and with significantly lower noise. The driveline consists of an electrically driven front axle with a self-locking Torsen differential, an 88 kW traction motor, an 8.5 kW fan motor and an electrically driven 12 kW hydraulic power unit with quiet gear pumps for steering, auxiliary functions and brush drive.

Battery and charging

The battery pack was developed by Bucher specifically for this machine: 80 kWh Li-ion with 335 V nominal voltage and up to 10 hours of operating time on a single charge. The 22 kW on-board charger with Type 2 inlet charges the battery in two to three hours at any public charging station. Depending on the selected regeneration level, the high-voltage battery is also charged during deceleration, extending the range further. Bucher emphasises that the robust, maintenance-free design gives a long service life and minimal cell ageing, and that a patented repair concept ensures safety for both the driver and the workshop. The noise level is 92 dB(A) measured according to 2000/14/EC, which makes night work in residential areas possible.

Articulated steering and sweeping equipment

The articulated steering provides exceptional agility and directional stability: the suction mouth always points in the direction of travel, so no dirty streaks are left behind in bends, and the rear section follows the front section's track exactly. The suction mouth is wide, floats between the front wheels and is mounted on a patented compensation mechanism, with an adjustable high-performance fan and a straight suction tube that minimises the risk of clogging. The three-brush system with trailing side brushes (Ø 800 mm, 0–120 rpm) and a third front brush gives a sweeping width of 2700 mm and makes it possible to sweep at two levels and reach hard-to-access places. The machine is only 1300 mm wide and 1999 mm high, which makes it well suited to multi-storey car parks and narrow streets.

Hopper, water and cab

The 2.0 m³ hopper is made of stainless steel 1.4003 and has a large, easy-to-clean filter screen that keeps the air speed up in the leaf season. It can be operated from outside or from the cab; the discharge height is 1555 mm and the discharge width 1043 mm. The water system holds 425 l in total – 275 l fresh water and 150 l service water under the hopper – and the service water tank can be used as a fresh water extension for combined sweeping and washing. The cab is ROPS-tested with two full-size seats with headrests, a walk-through layout, heated windscreen and glass doors. The machine is operated with the Smart-Con multifunction armrest and a 4.3-inch display for one-handed operation, with a CSense 10.1-inch touchscreen for extended settings and visual diagnostics. It can be equipped with driver assistance systems developed together with enway, and it can be connected to Bucher Connect.
