Bucher CityCat V20 series

The CityCat V20 is Bucher Municipal's flagship among compact sweepers in the 2 m³ class, and the series is available with a Euro 6d diesel engine (V20) or as a fully electric machine with an 80 kWh battery (V20e). With 2100 kg payload and 4800 kg gross vehicle weight, the machine combines a large load capacity with articulated steering and a driveline adapted to urban driving. Bucher describes the series as the result of many years of experience with compact sweepers: better suction, better connectivity, greater comfort and lower environmental impact.

Engine and driveline

The diesel version has a 2970 cm³ four-cylinder VM engine (R754EU6D) delivering 62 kW and 270 Nm, with AdBlue and exhaust aftertreatment to meet Euro 6d. The engine is also available in a Tier 4 Final version. The fuel tank holds 80 l and the AdBlue tank 14 l. The driveline is infinitely variable hydrostatic with two speed ranges and automatic, load-dependent electronic control. The working speed is 0–15 km/h, the transport speed 0–50 km/h and the gradeability up to 30%.

The electric V20e uses the same chassis, but with an 88 kW traction motor, 8.5 kW fan motor and 12 kW hydraulic power unit. It is powered by an 80 kWh, 335 V Li-ion battery pack with up to 10 hours of operating time, and a 22 kW on-board charger charges the battery in two to three hours.

Articulated steering and sweeping equipment

The articulated steering is the core of the concept. Because the suction mouth always points in the direction of travel, no dirty streaks are left behind in bends, and the rear section follows exactly the same track as the front section. The suction mouth is wide, floats between the front wheels and is mounted on a patented compensation mechanism, so it follows uneven surfaces without losing air speed. The straight suction tube is part of Bucher's “DNA” and gives minimal risk of clogging. With two trailing side brushes, the cleaning width is 2100 mm, with a third front brush 2700 mm, and with a pushed brush system up to 3040 mm. The side brushes are Ø 800 mm with infinitely variable speed 0–120 rpm and impact-protected suspension.

Hopper and water

The 2.0 m³ hopper is made of stainless steel and has a large, easy-to-clean filter screen that keeps the air speed up even in the leaf season. It can be operated both from outside and from the cab, and the discharge height is 1555 mm with a discharge width of 1043 mm. The water system holds 425 l in total – 275 l fresh water plus 150 l service water – and the service water tank can be used as an extension of the fresh water supply for combined sweeping and washing.

Cab and controls

The cab is ROPS-tested, with two full-size seats, a walk-through layout, heated windscreen and glass doors. The controls are gathered in the Smart-Con multifunction armrest with a 4.3-inch display for one-handed operation, supplemented by a CSense 10.1-inch touchscreen for extended settings and visual diagnostics. The machine can be connected to Bucher Connect for fleet management.
