Our verdict
The roller-less variant of the Rotak 36 R. Same Bosch DNA, slightly cheaper but you lose the stripes. If stripes are not a priority, it is the smarter buy.

Pros
- Bosch quality
- Lighter motor than Rotak 36 R
- Comb edges for cutting close to walls

Buying second-hand
£55–90 used. Same checks as Rotak 36 R — cable condition, motor noise. The lack of rear roller actually means fewer parts to fail; in practice these last longer than the rollered version.
