Professional Bosch cordless vacuum repair at the SATER service centre, Silmaču iela 6, Riga. We work with every Bosch cordless vacuum line — the Unlimited Serie 6 and Serie 8, the classic Athlet range, the compact Flexxo and the lightweight Readyy'y. With over 30 years of experience repairing consumer electronics we have built deep expertise in diagnosing and restoring German-engineered battery-powered vacuums. Bosch battery packs use high-quality lithium-ion cells, yet after two to four years of regular use their capacity drops and the BMS (Battery Management System) can lock the pack out after a deep discharge. We rebuild batteries using SONY, MOLICEL, SAMSUNG and PANASONIC cells and always fit a new BMS board — battery warranty is 6 months. Beyond batteries, we repair brushless motors, cyclone assemblies, brush rollers and control electronics. Diagnostics are done on-site — you bring the vacuum to Silmaču iela 6, we identify the fault and quote an exact repair price. SIA "Sadzīves tehnikas remonts SATER" has served thousands of customers and earned 186 Google reviews with an average rating of 4.3 stars. If the repair is not cost-effective, we will tell you honestly and return the unit with no obligation. All work except batteries carries a 3-month warranty.

Bosch Unlimited battery and BMS repair

Battery packs in Bosch Unlimited, Athlet and Flexxo cordless vacuums are built around 18650 or 21700 format lithium-ion cells with an integrated BMS board that monitors each cell's voltage, temperature and charging current. After two to four years of active use, cell capacity declines and the vacuum runs for just 5 to 10 minutes instead of the rated 30 to 60. The most insidious scenario is deep discharge — if the vacuum sits unused with a flat battery, cell voltage drops below the BMS threshold and the board locks the entire pack.

At the SATER service centre we fully disassemble the Bosch battery pack, measure every cell individually and decide whether to unlock the BMS and recover the cells with a controlled charge, or perform a complete rebuild. During a rebuild we replace all cells with new SONY, MOLICEL, SAMSUNG or PANASONIC high-capacity cells and fit a fresh BMS board. This is a full restoration of the vacuum's energy system, not a simple battery swap. Rebuilt batteries carry a 6-month warranty; all other work is covered by our 3-month warranty. We have been at Silmaču iela 6 in Riga since 1993.

Bosch cordless motor and cyclone diagnostics

Bosch cordless vacuums use high-speed brushless DC (BLDC) motors that reach up to 80,000 RPM on max power. These motors are durable, but prolonged use with a dirty filter or blocked airway causes overheating — the thermal sensor trips and shuts the motor down to protect the windings. Repeated overheating episodes can cause irreversible winding damage.

The Bosch cyclone system separates dust from the airflow before it reaches the HEPA filter. A crack in the cyclone cone or deformed seals lets air bypass the cyclone — suction drops and fine dust infiltrates the motor compartment, contaminating the windings and bearings. At SATER we perform a complete teardown of the motor and cyclone block, check every joint for airtightness, inspect rotor bearing condition, measure stator winding resistance and test the motor control electronics. Where needed we replace bearings, restore the cyclone cone and clear accumulated dust from the motor compartment. Call +371 67377002 or visit us at Silmaču iela 6.
